Gaseous methane (ch4) reacts with gaseous oxygen gas (o2) to produce gaseous carbon dioxide (co2) and gaseous water (h2o) . if 0.122g of water is produced from the reaction of 0.16g of methane and 0.25g of oxygen gas, calculate the percent yield of water.

The percent yield of water is 84.72 %

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

For methane:

Given mass of methane= 0.16 g

Molar mass of methane = 16 g/mol

Putting values in equation 1, we get:

For oxygen gas:

Given mass of oxygen gas = 0.25 g

Molar mass of oxygen gas = 32 g/mol

Putting values in equation 1, we get:

The chemical equation for the reaction is

By Stoichiometry of the reaction:

2 moles of oxygen gas reacts with 1 mole of methane

So, 0.008 moles of oxygen gas will react with = of methane

As, given amount of methane is more than the required amount. So, it is considered as an excess reagent.

Thus, oxygen gas is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of oxygen gas produces = 2 moles of water

So, 0.008 moles of oxygen gas will produce = of water

Mass of water=

To calculate the percentage yield of titanium (IV) chloride, we use the equation:

Experimental yield of water = 0.122

Theoretical yield of water = 0.144 g

Putting values in above equation, we get:

Hence, the percent yield of water is 84.72%.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
