The number of moles present in the FeSO4 are 0.055 mol.
<u>Explanation:</u>
- The mass of a substance containing the same number atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to 6.023 x 10^23. The moles of a substance can be determined by using the formula,
Number of moles = mass in grams / molecular mass
Given,
mass = 8.36 g,
molecular mass of FeSO4 = 151.908 g / mol
number of moles = 8.36 / 151.908
= 0.055 mol.
Answer:Hydrogen bonds
Explanation:
Hydrogen bonds occur between molecules when hydrogen is covalently bonded to a highly electronegative element in each molecule of the compound E.g water. Hydrogen bonds are intermolecular bond forces. They hold molecules of a substance together in a particular state of matter. They do not link atoms together but they form bridges between molecules. Hydrogen bonds exist in liquid, solid and gaseous states of matter.

Answer:
C3H8 + 5O2 => 3CO2 + 4H2O
Explanation:
Hydrocarbon combustion is the reaction between a hydrocarbon and O2 producing CO2 and water.
C3H8 + O2 => CO2 + H2O
First we balance the C and H.
C3H8 + O2 => 3CO2 + 4H2O
Now we balance O for the answer!
C3H8 + 5O2 => 3CO2 + 4H2O
