Atoms are the particles that all matter is made from.

Based on this reaction, find how many moles of co can be obtained starting with 7 mol ch4?

Klio2033 [76]

I will solve the question assuming the reaction used as below
1 CH4(g) + 1 H2O(g) ==> 1 CO(g) + 3 H<span>2(g)

In the reaction, CH4 is the reactant and CO is the wanted product. If you look at the coefficient of the substance, for every 1 mol of CH4 react there will be 1 mol of CO produced. So, if you have 7 moles of CH4 the amount of CO produced would be: 7 moles * 1/1= 7 moles of CO</span>

How many liters of carbon dioxide will 0.5 moles of lithium hydroxide (LiOH) absorb?

Elden [556K]

Answer : The volume of carbon dioxide will be, 5.6122 L

Solution : Given,

Moles of LiOH = 0.5 moles

Molar mass of carbon dioxide = 44 g/mole

Density of carbon dioxide = 0.00196 g/ml

First we have to calculate the mass of carbon dioxide.

The balanced reaction will be,

$2LiOH+CO_2\rightarrow Li_2CO_3+H_2O$

From the reaction we conclude that

As, 2 moles of LiOH absorbs 44 grams of carbon dioxide

So, 0.5 moles of LiOH absorbs $\frac{0.5moles}{2moles}\times 44g=11$ grams of carbon dioxide

Mass of carbon dioxide = 11 g

Density of carbon dioxide = 0.00196 g/ml

Now we have to calculate the volume of carbon dioxide.

$Density=\frac{Mass}{volume}$

$0.00196g/ml=\frac{11g}{volume}$

Volume of carbon dioxide = 5612.24 ml = 5.6122 L (1 L = 1000 ml)

Therefore, the volume of carbon dioxide will be, 5.6122 L

Which action will slow down the rate of a reaction

Burka [1]

Answer is - Decreasing surface area of a solid reactant, rate of reaction can be slowed down.

Explanation: The quantity of a reactant species consumed or the quantity of product species formed in unit time in a chemical reaction is called rate of reaction. With passage of time, concentration of reactant decreases and concentration of product increases. Rate of reaction depends on various factors like- concentration of reactant, temperature, nature of reactant, catalyst and surface area of reactant.

By increasing the concentration of the reactants, rate of the reaction increases.

Presence of catalyst increases the rate of reaction.

With increase in temperature, kinetic energy of molecules increases which results to more number of effective collisions, so, rate of reaction increases.

With increase in the surface area of reactant, more number of molecules can react at a time and by decreasing the surface area of solid reactant rate of the reaction will diminish/ decrease.
