What is the temperature of o3 gas if the average speed(actually the root mean square speed of the molecules is 750 m/s

Given the following balanced equation, determine the rate of reaction with respect to [Cl2]. If the rate of Cl2 loss is 4.44 × 1

PolarNik [594]

Answer:

8.88 x 10⁻² M/s

Explanation:

The rate of reaction for:

NO(g) + Cl₂ (g) ⇒ 2NOCl(g)

is rate = -ΔNO/Δt = -ΔCl2/Δt = 1/2 ΔNOCl/Δt

so ΔNOCl/Δt = 2 ΔCl2/Δt = 2 x 4.44 × 10⁻² M/s = 8.88 x 10⁻² M/s

In general given a reaction

aA + bB ⇒ cC + dD

rate = -1/a ΔA/Δt = -1/b ΔB/Δt = 1/c ΔC/Δt = 1/d ΔD/Δt

You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ioni

Phoenix [80]

Answer: Oil: covalent

Cornstarch: Covalent

Sodium chloride: Ionic

Sodium bicarbonate: Ionic

Explanation: Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.

1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.

4. Sodium bicarbonate, whose formula is $NaHCO_3$ is formed by transfer of electrons from sodium to $HCO_3$ .Ionic compounds are soluble in water.

A mixture of gaseous sulfur dioxide and oxygen are added to a reaction vessel and heated to 1000 K where they react to form SO3

nasty-shy [4]

Answer:

$Kp = 0.0410$

Explanation:

The reaction of gaseous sulfur dioxide and oxygen to form SO3 (g) is:

2SO₂(g) + O₂(g) ⇄ 2SO₃(g)

Kp is defined as the ratio of pressure of products and pressure of reactants:

$Kp = \frac{P_{SO_3}^2}{P_{SO_2}^2P_{O_2}}$

$Kp = \frac{0.0851atm^2}{0.669atm^2*0.395atm}$

$Kp = 0.0410$

I hope it helps!

Conditions for an experimental chemistry reaction require a temperature of 300 K. The temperature in the lab is 55 F. Which of t

OLga [1]

The suggested answers are for K=298 degrees and the nearest correct answer seems to be increase the room temperature by 22 degrees Fahrenheit. But by calculation, for 300 K, then convert 300k to degrees Celsius = 300-273.15=26.85 degrees celsius. Then convert the 26.85 to degrees F, so F=9/5C + 32= 48.33+32=80.33-55F (present room temperature)=25.33 degrees F to increase the room temperature by.
