Answer:

2.652 g/h.

Explanation:

Burn rate (in mg/min) = 44.2 mg/min

Burn rate (in m/h) =?

We'll begin by converting 44.2 mg/min to g/min. This can be obtained as follow:

1 mg/min = 0.001 g/min

Therefore,

44.2 mg/min = 44.2 mg/min × 0.001 g/min / 1 mg/min

44.2 mg/min = 0.0442 g/min

Finally, we shall convert 0.0442 g/min to g/h. This can be obtained as follow:

1 g/min = 60 g/h

Therefore,

0.0442 g/min = 0.0442 g/min × 60 g/h / 1 g/min

0.0442 g/min = 2.652 g/h

Therefore, 44.2 mg/min is equivalent to 2.652 g/h.

Thus, the burn rate (in m/h) is 2.652 g/h.

Answer:

Option C. 4.03 g

Explanation:

Firstly we analyse data.

12 % by mass, is a sort of concentration. It indicates that in 100 g of SOLUTION, we have 12 g of SOLUTE.

Density is the data that indicates grams of solution in volume of solution.

We need to determine, the volume of solution for the concentration

Density = mass / volume

1.05 g/mL = 100 g / volume

Volume =  100 g / 1.05 g/mL → 95.24 mL

Therefore our 12 g of solute are contained in 95.24 mL

Let's finish this by a rule of three.

95.24 mL contain 12 g of sucrose

Our sample of 32 mL may contain ( 32 . 12) / 95.24 = 4.03 g

Answer:

2.41 * 10^24 atoms of carbon present in the products.

Explanation:

First, we need to find the moles of carbon in the products in order to find the number of atoms.

We see that in the chemical formula, carbon belongs to the compound known as glucose. To get the amount of moles of carbon, we need to divide my the amount of carbon within glucose (in grams) from the total amu ( or grams) of glucose to get the moles.

C6 = 72.066.

C6H12O6 = 180.156

72.066/180.156 = 0.4000199827 moles of Carbon within the Glucose compound

Now we will convert to atoms/molecules by multiplying the moles by avogadro's number..

0.4000199827 moles C * 6.022*[tex]10^{23}[/tex] = 2.408920336 *[tex]10^{24}[/tex] atoms of Carbon present in the products

*Note --> this can be estimated to 2.41 * [tex]10^{24}[/tex] atoms of Carbon

Answer:

Gibbs free energy equation

Explanation:

Answer:

0.36M HCl

Explanation:

The reaction of Mg(OH)₂ with HCl is:

Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O

Where 1 mole of magnesium hydroxide reacts with 2 moles of HCl

To solve this question, we need to find the moles of Mg(OH)₂ that reacted and, with chemical equation, solve for the moles of HCl and its molarity (Using the 10.00mL = 0.01000L) as follows:

Moles of Mg(OH)₂:

18mL = 0.018L * (0.100mol / L) = 0.0018 moles Mg(OH)₂

Moles HCl:

0.0018 moles Mg(OH)₂ * (2 moles HCl / mol Mg(OH)₂) = 0.0036 moles HCl

Molarity HCl:

0.0036 moles HCl / 0.0100L =

Answer:

253.5mL of Ba(OH)₂ are required to neutralize the HCl solution

The pH at equivalence point is = 7

Explanation:

The reaction of Ba(OH)₂ with HCl is:

Ba(OH)₂ + 2HCl → BaCl₂ + 2H₂O

First, we need to find moles of HCl. With these moles and the chemical equation we can find the moles of Ba(OH)₂ and the volume required:

Moles HCl:

75.0mL = 0.075L * (0.845mol / 1L) = 0.063375moles HCl

Moles Ba(OH)₂:

0.06338moles HCl * (1mol Ba(OH)₂ / 2mol HCl) = 0.03169 moles Ba(OH)₂

Volume of the 0.125M Ba(OH)₂:

0.03169 moles Ba(OH)₂ * (1L / 0.125mol) = 0.2535L are required =

253.5mL of Ba(OH)₂ are required to neutralize the HCl solution

As the titration was of a strong acid, HCl, with a strong base, Ba(OH)₂, the pH at equivalence point is = 7

Answer:

the Product

Explanation:

Answer:

PCl3 - trigonal pyramidal <109 degrees

SCl2 - bent<109 degrees

SiF4 - tetrahedral 109 degrees

Explanation:

The shape of all three molecules derive from a tetrahedral arrangement of electron pairs.

However, in PCl3 there is a lone pair of electrons on P and three bond pairs. This leads to the observance of a trigonal pyramidal geometry with bond angle <109 degrees.

In SCl2, there are four regions of electron density around S, two lone pairs and two bond pairs leading to a bent molecular geometry with bond angle <109 degrees.

In SiF4, there are four bond pairs and no lone pair. The molecular geometry is tetrahedral with a bond angle of 109 degrees.

One major characteristic they have in common is they are metals.

All solutions are mixtures of two or more substances, but unless the mixture has a homogeneous distribution of solutes in the solvent, then the mixture is not a solution. Therefore, all mixtures are not solutions.

Answer:

377mL is the volume of the solution

Explanation:

A 0.140M solution of CuNO₃ contains 0.140 moles of CuNO₃ per liter of solution. Thus, we need to convert first the mass of CuNO₃ to moles using its molar mass and, with the moles available, we can find the volume of the solution, thus:

Moles CuNO₃ -Molar mass: 125.55g/mol:

6.63g * (1mol / 125.55g) = 0.0528 moles of CuNO₃.

Volume of solution:

0.0528 moles of CuNO₃ * (1L / 0.140 moles CuNO₃) = 0.377L

0.377L * (1000mL / 1L) =

d. Mg and HCl(Magnesium and Hydrochloric acid)

When magnesium reacts with Hydrochloric acid, It leads to the formation of Magnesium chloride as a salt, and hydrogen gas is liberated.

[tex]Mg+2HCl--- > MgCl_2+H_2[/tex]

When a metal reacts with an acid, it leads to the liberation of hydrogen gas and the production of their respective salt.

Answer:

Molarity = 0.3 M

Explanation:

Given data:

Moles of NaOH = 0.720 mol

Volume of water = 2.40 L

Molarity = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 0.720 mol / 2.40 L

Molarity = 0.3 mol/L

Molarity = 0.3 M

Answer:

Answer:

1. They will react.

2. 2HCI + Zn —> ZnCl2 + H2

Explanation:

1. From the question given above,

We can see that Zn is higher than H in the activity series.

NOTE: Elements higher (i.e at the top) in the activity series will displace those lower (i.e at the bottom) in the series. Thus, Zn is higher in the series than H. Therefore, Zn will displace H from solution. Hence, they will react.

2. The product obtained from the reaction can be seen as follow:

HCI + Zn —> ZnCl2 + H2

The above equation can be balance as follow:

There are 2 atoms of H on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:

2HCI + Zn —> ZnCl2 + H2

Answer:

0.9612 g

Explanation:

First we calculate how many moles are there in 3.00 g of CCl₃F, using its molar mass:

Now, we need to calculate how many grams of N₂O would have that same number of molecules, or in other words, the same amount of moles.

Thus we calculate how many grams would 0.0218 moles of N₂O weigh, using the molar mass of N₂O :

The  mass of dinitrogen monoxide is 0.9612 g

The number of  moles are there in 3.00 g of CCl₃F, using its molar mass:

= 3.00 g CCl₃F ÷ 137.37 g/mol

= 0.0218 mol CCl₃F

Now the mass should be

=[ 0.0218 mol N₂O ×  44.013 g/mol

= 0.9612 g N₂O

Answer:

Heat the molecule

Explanation:

Since most bonds require energy to form, they also give off energy when they are broken. But before most bonds break, the molecule has to be heated. Then the atoms start to move, and when they move too much, the bond breaks. Molecules that require less energy to break than they give off when broken are called fuels.

Answer:

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
