Mass of Oxygen is: 0.784gm

Potassium chlorate is KClO3 and the decomposition looks like this...

2KClO3 ==> 2KCl + 3O2

4.50 g KClO3 x 1 mole/122.55 g = 0.0367 moles

0.0367 moles KClO3 x 3 moles O2/2 moles KClO3 = 0.0245 moles O2 (see mole ratio in balanced equation)

mass of O2 = 0.0245 moles O2 x 32 g/mole = 0.784 g O2 formed

<h3>What is the pressure of a mixture of CO2 and KR?</h3>

A mixture of CO2 and Kr weighs 37.0 g and exerts a pressure of 0.737 atm in its container. is expensive, you wish to recover it from the mixture.

<h3>How much oxygen is created when one mole of potassium chlorate breaks down?</h3>

in the reaction 2K C lO3 2K C l + 3O2 K C lO3? This demonstrates that 3 moles of oxygen gas are created for every 2 moles of degraded potassium chlorate.

<h3>How is high pressure liquid CO2 produced?</h3>

High pressure liquid CO 2 is produced by compressing the gaseous CO 2 in multistage compressors to pressures in the neighbourhood of 69 bar (1000,76 psi) pressure, then cooling it to around 18 °C (64,4 °F). It is customarily filled into specially constructed steel cylinders.

A piece of unknown metal with mass 68.6 g is heated to an initial temperature of 100 °C and dropped into 84 g of water (with an
laila [671]

The specific heat of metal is c = 3.433 J/g*⁰C.

<h3>Further explanation</h3>

Given

mass of metal = 68.6 g

t metal = 100 °C

mass water = 84 g

t water = 20 °C

final temperature = 52.1  °C

Required

The specific heat

Solution

Heat can be formulated :

Q = m.c.Δt

Q absorbed by water = Q released by metal

84 x 4.184 x (52.1-20)=68.6 x c x (100-52.1)

11281.738=3285.94 x c

c = 3.433 J/g*⁰C.

A reaction is in equilibrium as shown: A + B C + D. Calculate the equilibrium constant in the final concentrations stabilized at
Butoxors [25]

Answer:

K = 0.167

Explanation:

The equilibrium constant, K of a reaction, is defined as the ratio of the concentrations of products and concentrations of reactants.

For the reactions:

A + B ⇄ C + D

For the definition, K is:

K = [C] [D] / [A] [B]

K = [4.0M] [4.0M] / [9.6M] [10.0M]

<h3>K = 0.167</h3>
