Answer:
True, in as far as greater magnitude = greater power.
Answer:
Chromium-51 has 24 protons, 28 neutrons, and 24 electrons.
Explanation:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
Answer is: 89 g of CaCO₃ is <span>equired to prepare 50.0g of CaO.
</span>Chemical reaction: CaCO₃ → CaO + CO₂.
m(CaO) = 50,0 g.
m(CaCO₃) = ?
n(CaO) = m(CaO) ÷ M(CaO).
n(CaO) = 50,0 g ÷ 56 g/mol.
n(CaO) = 0,89 mol.
from reaction: n(CaCO₃) : n(CaO) = 1 : 1.
n(CaCO₃) = n(CaO).
n(CaCO₃) = 0,89 mol.
m(CaCO₃) = m(CaCO₃) · M(CaCO₃).
m(CaCO₃) = 0,89 mol · 100 g/mol
m(CaCO₃) = 89 g.
n - amount of substance.
Explanation:
The source of energy in nuclear weapons is to make the weapons god and make them nice and strong but I dont know so thanks for the points
(4)2-8-7-1
The maximum number of electrons in the second two shells is 8, but since there is 7 in the third she'll and 1 in the fourth, that means that one electron was moved to the last shell, putting the atom in the excited state.
