if 12 molecules of methane reacted with plenty of oxygen, we should expect to produce____ molecules of car on dioxide and _____

ziro4ka [17]

Answer:

12 molecules of carbon dioxide

24 molecules of water

Explanation:

Given parameters:

Number of molecules of methane = 12 molecules

Unknown:

Number of molecules of carbon dioxide = ?

Number of molecules of water = ?

Solution:

The given amount of methane is the limiting reagent in this reaction. By this, we can ascertain the amount of products that will be formed and the extent of the reaction.

We first write the balanced chemical equation for this reaction;

CH₄ + 2O₂ → CO₂ + 2H₂O

From balanced equation;

1 mole of methane produced 1 mole of carbon dioxide

12 molecules of methane will produce 12 molecules of carbon dioxide

Also;

1 mole of methane produced 2 moles of water;

12 molecules of methane will produce (12 x 2)molecules = 24 molecules of water

Write an equation for the hydrogenation of glyceryl trilinolenate, a fat formed from glycerol and three linolenic acid molecules

Tomtit [17]

Balanced chemical equation for the hydrogenation of glyceryl trilinolenate:

C₅₇H₉₂O₆ + 9H₂ → C₅₇H₁₁₀O₆.

Linolenic acid (octadecatrienoic acids ) is a type of fatty acid. It has 18 carbon atoms chain and three double bonds. So trilinolenate has nine double bonds.

Trilinolenate is the form of triglyceride esters of linolenic acid.

Hydrogenation is addition of hydrogen atoms at both sides of a double bond.

Why are the levels at the top smaller and the ones on the bottom larger in the energy pyramid? HELP ASAP

nalin [4]

Because as each organism goes up, there's less energy being given. Here's an example.

Take a plant, it has 100% of its energy. Then it's eaten by a deer, which could be the Primary Consumer. The deer has 10% of the beginning energy. Then, the deer is eaten by a wolf, a Secondary Consumer, which then has 1% of the energy.
