Answer:

C₃H₈ has a higher boiling point than C₂H₆

Explanation:

The boiling point is the temperature at which the intermolecular bonds holding molecules in liquid form are overcome and change the state into a gas. C₃H₈ experiences stronger intermolecular bonds then C₂H₆ because it has more carbons. While the strength of each bond is the same between the two molecules, C₃H₈ has more opportunities to create these bonds due to the higher carbon count. The more bountiful the intermolecular bonds, the more energy is needed to overcome them all. Thus, C₃H₈ has a higher boiling point.

Answer:

Rate law: = $k[CS_2]^1$

Explanation:

Given:

t $[CS_2]$

0.100 $2.7 \times 10^{-7}$

0.080 $2.2 \times 10^{-7}$

0.055 $1.5\times 10^{-7}$

0.044 $1.2\times 10^{-7}$

Rate law for the given reaction: $k[CS_2]^n$

Where, n is the order of the reaction.

Divide rate 1 with rate 3

$\frac{0.100}{0.055} =\frac{k[CS_2 (1)]^n}{k[CS_2 (3)]^n} \\\frac{0.100}{0.055} =\frac{k[2.7 \times 10^{-7}]^n}{k[1.5\times 10^{-7}]^n}\\1.81=[1.8]^n\\ n=1$

So, rate law = $k[CS_2]^1$

What is the word equation of photodecomposition?

Oksi-84 [34.3K]

Answer:

I have for Decompostion

Explanation:

A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation: AB → A + B. In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction

What are the missing coefficients for the skeleton equation below?

Kruka [31]

Answer:

4, 3 , 2 and 6

Explanation:

The reaction equation is given as;

NH₃ + O₂ → N₂ + H₂O

Now, we need to balance the reaction equation;

NH₃ + O₂ → N₂ + H₂O

put the numbers a,b,c and d;

aNH₃ + bO₂ → cN₂ + dH₂O

We need to balance the equation algebraically, ;

Conserving N;

a = 2c

Conserving H;

3a = 2d

Conserving O;

2b = d

Now, let c = 1, a = 2, d = 3 and b = $\frac{3}{2}$

multiply through by 2;

a = 4, b = 3, c = 2 and d = 6

Insert the parameters:

4NH₃ + 3O₂ → 2N₂ + 6H₂O
