Second ionization energy is defined by the equation: it is the energy needed to remove second electron from each job in 1 mole of gaseous 1+ ions to give gaseous 2+ ions. More ionization energies. You can then have as many successive ionization energies as there are electrons in the original atom.
Answer:
see below
Explanation:
1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms
calculate the number of atomsin 80.45g Mg
Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g
= 1.99*10^24 atoms
2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms
calculate the mass using
= 12.01 g C / 6.02*10^23 atoms * 100 atoms
= 1.99 * 10^-21 g
Answer:
The answer to your question is 6.54 g of H₂O
Explanation:
Data
mass of water = ?
mass of carbon dioxide = 16 g
Balanced chemical reaction
H₂CO₃ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the products
H₂O = (1 x 2) + (1 x 16) = 2 + 16 = 18 g
CO₂ = (1 x 12) + (16 x 2) = 12 + 32 = 44 g
2.- Use proportions and cross multiplication to solve this problem.
18 g of H₂O -------------------- 44 g of CO₂
x -------------------- 16 g of CO₂
x = (16 x 18) / 44
x = 288/44
x = 6.54 g of H₂O
Answer:
sound is given off
Explanation:
due to a number of scientific research sound that is given off of an object is not due to a chemical reaction.
<span>if we have 10.50 g of sugar we have 1050 mg In 5 g of the chocolate bar, we have 5/17 x 1050 = 308.8 mg
% sugar = 10.50 / 17 % = 61.76 %</span>
