1 When 25 cm of 1.0 mol/dmº copper sulfate solution was mixed vith an excess of zinc
powder, the temperature of the solution rose by 50.6 °C. Calculate the energy change
for the reaction in kJ/mol.
CuSO4(aq) + Zn(s) + Cu(s) + ZnSO4(aq)
?

Answers

Answer:

See explanation

Explanation:

From the formula for heat;

q (enthalpy change) = (mass of solution) x (specific heat capacity) x (temperature change)

Since the density and heat capacity of the solution are the same as that of pure water.

Mass of copper sulphate solution = 50 g

Heat = 50 * 4.18 * 50.6°C

Heat = 10575.4 J

Number of moles = 1 * 25/1000 = 0.025 moles

10575.4 J/ 0.025 moles = 432016 J/mol/1000

= 423 KJ/mol

or

q = - 423 KJ/mol

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.

Explanation:

We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.

All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!

 The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space! 

I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan.  Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced  from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.

Oxycodone (C18H21NO4), a narcotic analgesic, is a weak base with pKb = 5.47. Calculate the pH of a .00250 M oxycodone solution.

Answers

Answer: The pH of a 0.00250 M oxycodone solution is 9.96

Explanation:

[tex]C_{18}H_{21}NO_4\rightarrow C_{18}H_{20}NO_3^++OH^-[/tex]

 cM                     0  M         0 M

[tex]c-c\alpha[/tex]        [tex]c\alpha[/tex]         [tex]c\times \alpha[/tex]

So dissociation constant will be:

[tex]K_b=\frac{(c\alpha)^{2}}{c-c\alpha}[/tex]

Give c= 0.00250 M and [tex]pK_b[/tex] = 5.47

[tex]pK_b=-log(K_b)[/tex]

[tex]K_b=3.38\times 10^{-6}[/tex]

Putting in the values we get:

[tex]3.38\times 10^{-6}=\frac{(0.00250\times \alpha)^2}{(0.00250-0.00250\times \alpha)}[/tex]

[tex](\alpha)=0.036[/tex]

[tex][OH^-]=c\times \alpha[/tex]

[tex][OH^-]=0.00250\times 0.0369=9\times 10^{-5}[/tex]

Also [tex]pOH=-log[OH^-][/tex]

[tex]pOH=-log[9\times 10^{-5}]=4.04[/tex]

[tex]pH+pOH=14[/tex]

[tex]pH=14-404=9.96[/tex]

Thus pH of a 0.00250 M oxycodone solution is 9.96

Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. Titanium tetrachloride (TiCl4) is extracted from titanium oxide using chlorine and coke (carbon). TiO2(s) + C(s) + 2 Cl2(g) TiCl4(s) + CO2(g) (a) What mass of Cl2 gas is needed to react with 1.60 mol TiO2? g (b) What mass of C is needed to react with 1.60 mol of TiO2? g (c) What is the mass of all the products formed by reaction with 1.60 mol of TiO2? g

Answers

Answer:

a) 226.6 grams of Cl₂

b) 19.2 grams of C

c) 303.2 grams of TiCl₄ and 70.4 grams of CO₂

Explanation:

The balanced chemical reaction is the following:

TiO₂(s) + C(s) + 2 Cl₂(g) → TiCl₄(s) + CO₂(g)

(a) What mass of Cl₂ gas is needed to react with 1.60 mol TiO₂?

From the chemical equation, 1 mol of TiO₂ reacts with 2 moles of Cl₂. So, the stoichiometric ratio is 2 mol Cl₂/1 mol TiO₂. We multiply this ratio by the moles of TiO₂ we have to calculate the moles of Cl₂ we need:

1.60 mol TiO₂ x 2 mol Cl₂/1 mol TiO₂ = 3.2 mol Cl₂

Now, we convert from moles to mass by using the molecular weight (MW) of Cl₂:

MW(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol

mass of Cl₂= 3.2 mol x 70.8 g/mol = 226.6 g

Therefore, 226.6 grams of Cl₂ are needed to react with 1.6 mol of TiO₂.

(b) What mass of C is needed to react with 1.60 mol of TiO₂?

From the chemical equation, 1 mol of TiO₂ reacts with 1 moles of C(s). So, the stoichiometric ratio is 1 mol C/1 mol TiO₂. We multiply this ratio by the moles of TiO₂ we have to calculate the moles of C(s) we need:

1.60 mol TiO₂ x 1 mol C(s)/1 mol TiO₂ = 1.60 mol C(s)

So, we convert the moles of C(s) to grams as follows:

MW(C) = 12 g/mol

1.60 mol x 12 g/mol = 19.2 g C(s)

Therefore, a mass of 19.2 grams of C is needed to react with 1.60 mol of TiO₂.

(c) What is the mass of all the products formed by reaction with 1.60 mol of TiO₂?

From the chemical equation, we can notice that 1 mol of TiO₂ produces 1 mol of TiCl₄ and 1 mol of CO₂. So, from 1.60 moles of TiO₂, 1 mol of each product will be produced:

1 mol TiO₂/1 mol TiCl₄ ⇒ 1.60 mol TiO₂/1.60 mol TiCl₄

1 mol TiO₂/1 mol CO₂ ⇒ 1.60 mol TiO₂/1.60 mol CO₂

Finally, we convert the moles to grams by using the molecular weight of each compound:

MW(TiCl₄) = 47.9 g/mol Ti + (35.4 g/mol x 4 Cl) = 189.5 g/mol

1.60 mol x 189.5 g/mol = 303.2 g

MW(CO₂) = 12 g/mol C + (16 g/mol x 2 O) = 44 g/mol

1.60 mol x 44 g/mol = 70.4 g

Therefore, from the reaction of 1.60 mol of TiO₂ are formed 303.2 grams of TiCl₄ and 70.4 grams of CO₂.

Explanation:

A wildfire destroys most of the plant life in a forest. Animals would be pushed out and lose their homes.

What is wildfire?

An unplanned, uncontrolled, and unpredictable fire inside an area of flammable vegetation is known by several names, including wildfire, bushfire, bushfire, wildland fire, and rural fire. A wildfire may be more precisely referred to by the terms bushfire, desert fire, forest fire, hill fire, peatland fire, prairie fire, vegetable fire, or veld fire, depending on the kind of vegetation that is present.

Wildfires are separate from controlled and prescribed burning, which is a good human use of wildland fire, even though controlled burns have the potential to turn into wildfires. Wildfires likely started shortly after terrestrial plants first appeared, which occurred in the Silurian epoch 419 million years ago, according to fossil charcoal. A wildfire destroys most of the plant life in a forest. Animals would be pushed out and lose their homes.

Therefore, animals would be pushed out and lose their homes.

In the atmosphere, it is more common to find two oxygen molecules joined together than to find a single atom of oxygen. Why? What would that molecule look like? What would this molecule be called?

Answers

Answer:

See explanation

Explanation:

Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.

In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.

An image of the oxygen molecule is attached to this answer.

This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).

how is it proved that carbon is present in sugar?​

Answers

Answer:

In all living organisms, in substances like carbohydrate, starch, urea etc. To prove sugar contains carbon, take a little amount of sugar in spoon and heat it gently till it melts and turned into yellowish color. On further heating it changes into brown colored mass and then black, which is charcoal.

Take a small bit of sugar on a spoon and slowly heat it until it melts and turns a yellowish tint to demonstrate that it contains carbon. As it continues to heat up, it transforms into charcoal, which is a black mass first.

What is Charcoal ?

Strongly heating wood with little oxygen produces charcoal, a light black carbon residue that has been stripped of all water and volatile components.

Since the beginning of time, charcoal has been used for a wide variety of reasons, including art and healing, but its most significant usage has been as a metallurgical fuel. The typical fuel for a blacksmith's forge and other uses requiring high heat is charcoal.

Sugar breaks down into carbon and water when it is heated. Water is still a chemical, but it can't be heated

Thus,  As it continues to heat up, it transforms into charcoal, which is a black mass first.
