mass is the amount of matter in an object, and volume is the amount of space something takes up
<h3>
Answer:</h3>
- Balanced Equation; 2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
- Why balance?: To obey the law of conservation of mass
- Subscripts can not be changed, since they show the actual number of atoms of each element in a compound.
<h3>
Explanation:</h3>
- The balanced equation for the reaction between the iron metal and sulfuric acid to produces iron (III) sulfate and hydrogen gas is given by;
2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
- Balancing chemical equations ensures that they obey the law of conservation of mass which requires the mass of reactants and the mass of products to be equal.
- Balancing is done by putting coefficients on reactants and products while not affecting the subscripts as subscripts show the actual number of atoms of an element in a compound.
Answer: 0.887 g of
should be added to excess HCl(aq).
Explanation:
According to ideal gas equation:

P = pressure of gas = 805 torr = 1.06 atm (760torr=1atm)
V = Volume of gas = 235 ml = 0.235 L
n = number of moles = ?
R = gas constant =
T =temperature =



According to stoichiometry:
1 mole of chlorine is produced by = 1 mole of 
Thus 0.0102 moles of chlorine is produced by =
moles of 
Mass of
=
0.887 g of
should be added to excess HCl(aq).
That means that the amount of energy can only be certain numbers, as if
energy came in tiny packets, and the in-between amounts don't exist.
Another example of a measurement in nature that is quantized is
electric charge.
