What happens when additional electrons were placed in the atom?

1 answer:

3 0

They aren't actually placed into the atom, they surround it in the "electron cloud" but if you add electrons, the charge of your atom becomes negative. If your remove them, the charge becomes positive

What is the percent composition of hydrogen in vinegar (CH3COOH)?

barxatty [35]

Answer:

%H = 6.72 %

Explanation:

Percent composition of an element is the total mass of that element divided by the molecular mass of compound (or molecular mass) of which it is present in.

So,

Percent composition of Hydrogen will be given as,

%H = Total mass of H / Molecular Mass of Acetic Acid × 100

So,

Total Mass of H = 1.01 × 4 = 4.04 g

Molecular Mass of Acetic acid = 60.052 g/mol

Putting values in above formula,

%H = 4.04 g/mol ÷ 60.052 g/mol × 100

%H = 6.72 %

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?

Marysya12 [62]

4 moles of water are produced

Explanation:

4 moles of water are produced when 5 moles of hydrogen is reacted with 2 moles of oxygen gas
The balanced equation given is when 2 moles of hydrogen reacts with 1 mole of oxygen and it forms 2 moles of water.
The equation we have to solve is the 5 moles of hydrogen is reacting with 2 moles of oxygen gas, we can write the equation as $5H_{2} +2O_{2} --> 4H_{2} O + H_{2}$
This is the balanced equation when 5 moles of hydrogen reacts with 2 moles of oxygen. The balanced equation means the number of hydrogen atoms and oxygen atoms on both sides would be equal in number.
