Given

Reaction

C+02 = CO2

Required

The equilibrium constant

Solution

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction  

pA + qB -----> mC + nD  

[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]

So for the reaction :

C+O₂ ⇔ CO₂

[tex]\tt Kc=\dfrac{[CO_2]}{[C][O_2]}[/tex]

Answer:

The manner in which objects will move is determined by the answer to this question. Unbalanced forces will cause objects to change their state of motion

Explanation:

Since these two forces are of equal magnitude and in opposite directions, they balance each other.

Answer:

balance force are those force whose resultant force is zero and unbalanced force are those whose resultant are non zero

Stock solutions contain a standardized concentration of the solute in a solution. To prepare 50 mL of solution with a ratio of 1:1000 solution, 5 gms of the drug will be required.

Dilution is the property of the solution with a less amount of solute concentration than the stock solution. A dilute solution is prepared by the addition of more solvent.

The addition of the solvent in a solution decreases the molar concentration which leads to dilution.

The ratio of 1:1000 means that 1 gm of the drug is present in 1000 mL (1L) of solution.

1000 mL = 1 gm × 500 mL × X gm

Here, the X represents the 0.5 gm of drug dissolved in 500 mL.

The amount of drug used is calculated as,

5 mL ÷ 50 ml = 0.5 g ÷ X g

X = 0.5 × 50 ÷ 5

= 5 gm

Therefore, 5 gm of the drug is required to prepare 50 mL of solution.

Answer:

¹/3 C3H8(g) + ⁵/3 O2(g)

Explanation:

The coefficient before every molecule is representative of the number of moles. We can represent it in ration form so as to calculate the question;

C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(l) means;

For every 1 mole of C₃H₈(g) and 5 moles of  O₂(g) produces  3 moles of  CO₂(g) and 4 moles of H₂O(l).

Therefore to produce 1.00 mole of CO₂(g);

We represent it in ratio;

C₃H₈(g) : CO₂(g)

We can write:

5/4 = 3,8/x

Solving for x:

x = 3,04 mols of H2O

Calculating the H2O mass:

M H2O = 18 g/mol

n = m/M

Solving for m:

m = 54,72 g of water

****************************

Using the same, but with molar mass:

M CO2 = 44 g/mol => 3 x 44 = 132 g

M O2 = 32 g/mol => 5 x 32 = 160 g

160/132 = x/90,6

solving for x:

x = 109,82 g if CO2

Molecular solid

Explanation:

A molecular solid has a low melting point, they are soft and do not conduct electricity.

We have been told in the question that the solid does not really dissolve in water and it's solution does not improve the electrical conductivity of water. Hence, it must be a molecular solid.

Answer:

Its particles are evenly distributed.

Explanation:

Solutions are homogenous mixtures of solutes and solvents. In a solution the solute particles are evenly distributed in the solvent.

Here are some characteristics of solutions:

A characteristic of a solution is that its particles are evenly distributed.

A characteristic of a solution is that its particles are evenly distributed. In a solution, the solute (substance being dissolved) is uniformly distributed and mixed with the solvent (the substance doing the dissolving) at the molecular or ionic level.

The particles of the solute become thoroughly dispersed and do not settle out over time. Solutions are generally clear and do not scatter light, unlike suspensions or colloids which may exhibit light scattering due to the presence of larger particles.

Answer:

1.593 moles

Explanation:

Therefore, 1.593 moles are equal to 89.23 g of calcium oxide.

Answer:

9.64 × 10²³ molecules

Explanation:

Given data:

Mass of calcium oxide = 89.23 g

Number of molecules = ?

Solution:

First of all we will calculate the number of moles of calcium oxide.

Number of moles = mass/molar mass

Number of moles = 89.23 g/ 56.1 g/mol

Number of moles = 1.6 mol

Number of molecules;

1 mole contain 6.022 × 10²³ molecules

1.6 mol × 6.022 × 10²³ molecules / 1mol

9.64 × 10²³ molecules

The number 6.022 × 10²³ is called Avogadro number.

When converting from liters to moles or moles to liters, you will use the equality 1 mole=22.4 L for a gas at STP.

If you have moles and want to convert to (Volume) liters, 1 mole = 22.4 L is the conversion factor that can be used.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Various forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how we can determine the volume for each of these shapes. One mole of any gas have 22.4 L at STP.

Answer:

d. Urea nitrate

Explanation:

Urea nitrate is a fertilizer-based explosive that is produced in one step by reaction of urea with nitric acid. The is an exothermic reaction, therefore, necessary steps and precautions must be taken to ensure safety during the process. The equation of the reaction is given below:

(NH₂)₂CO (aq) + HNO₃ (aq) → (NH₂)₂COHNO₃ (s)

It is as easily-made explosive and can also be used as a catalyst in Diels-Alder reactions of aromatic amines.

In the presence of water, urea nitrate readily decomposes to its original components, urea and nitric acid.

On its own, urea  is commonly used as a deicer for sidewalks as it is a noncorrosive de-icing material. However, it is a more costly method of deicing,  compared to other methods and it is best used where water runs off into vegetation than into a water-body or a storm drain because of its high-oxygen demand which could result in its reducing the oxygen level of the water body. It It is readily found in nature (in our urine) and is also  synthesized artificially.  It has a very high nitrogen content, and is most often used as a nitrogen‐based fertilizer.

The volume of carbon monoxide is produced when 1.20 L of dicyanoacetylene reacts is

Stoichiometry of any reaction tells about rhe relative amount of substance present before and after the completion of any chemical reaction.

Given balanced chemical reaction between dicyanoacetylene and ozone to produce carbon monoxide and nitrogen is:

3C₄N₂ + 4O₃ → 12CO + 3N₂

From the stoichiometry of the reaction it is clear that:
3 liters of C₄N₂ =  produces 12 liters of CO

1.20 liters of C₄N₂ =  produces 12/3×1.20=4.8 liters of CO

Answer:

NaOH + HCl —> NaCl + H₂O

Explanation:

From the question given above, we obtained the following equation:

4NaOH + 4HCl —> NaCl + H₂O

The equation can be balance as follow:

4NaOH + 4HCl —> NaCl + H₂O

There are 4 atoms of Na on the left side and 1 atom on the right side. It can be balance by putting 4 in front of NaCl as shown below:

4NaOH + 4HCl —> 4NaCl + H₂O

There are a total of 8 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 4 in front of H₂O as shown below:

4NaOH + 4HCl —> 4NaCl + 4H₂O

Next, divide through by 4 to express the equation with the lowest coefficients.

NaOH + HCl —> NaCl + H₂O

Now the equation is balanced.
