Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

Balance each reaction and write its reaction quotient, Qc:(a) NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)
AleksAgata [21]

When we balance the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We will get

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

Solution:

Balancing the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of Cl

2NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of N, O.

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

We will get the balanced equation

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

The reaction quotient will be

    Qc = [product] / [reactant]

     Qc ​= [NO₂(g) + Cl₂(g)] / [NO₂Cl(g)]

How many liters would you need to make a 0.8 M solution with 20 grams of lithium chloride?
worty [1.4K]

Answer:

0.5875L

Explanation:

concentration = mole/ volume

n(LiCl) = 20 / (7 + 35.5) = 0.47 mol

volume = mole / conc.

volume = 0.47 /0.8

= 0.5875 dm³ = 0.5875L

What is the percentage of hydrogen in c2h4
jarptica [38.1K]

Ethylene- C2H4 = 85.7% Carbon and 14.3% Hydrogen


Find the atomic masses for each element and multiply it by the number of atoms in the compound, then add.


C- 12.0 * 2= 24.0


H- 1.00 * 4= 4.00


-----------------------


28.0


Take the masses for each element and divide it by the total mass. Then change the answer to get the percent.


C 24.0 / 28.0= .857 = 85.7%


H 4.00 / 28.0= .143 = 14.3%


<h3>Ethylene is 85.7% Carbon and 14.3% Hydrogen </h3>
