Answer:
It is a reactant that produces smaller amount of product.
Explanation:
" The limiting reactant is a reactant that control the amount of product in chemical reaction because of its smaller amount"
Consider the example:
2 H₂ + O₂ → 2H₂O
two moles of hydrogen react with one moles of oxygen and produces two moles of water. when we take two mole of hydrogen and two mole of oxygen than again two mole of water is produced because hydrogen is limiting reactant and one mole of oxygen left un reacted.
Identification of limiting reactant:
Calculate the number of moles of reactant.
compare it with number of moles of product with help of balance chemical equation.
identify the reactant which produces less number of moles of product.
1.17×6×1023
Wich equals 7.02×1023
Your final answer is 7.02×1023
Answer:

d) True
e) False (Non metals are bad conductor of heat and electricity )
Answer:Number of proton present in the nucleus of an atom of sulfur is 16.
Explanation:
Protons, neutrons and electrons are subatomic particles of an atom.
Atomic number of an atom is equal to the total number of protons present in the nucleus of an atom.
Z = total number of protons
Atomic mass of an atom is defined as sum of the number of protons and neutrons present in the nucleus of an atom.
In neutral atom there are equal number of protons and electron.
A = number of proton + number of neutrons
According to question, there are 16 electrons in neutral atom of Sulfur.
in a neutral atom:
Number of electrons = Number of protons = 16
Number of proton present in the nucleus of an atom of sulfur is 16.
