Answer:
Van der waal's force of attraction
Explanation:
Van der waal's force of attraction
Forces of Van der Waals involve attraction and repulsion among atoms, particles, and surfaces as well as many other intermolecular forces. These vary from covalent and ionic bonding in that they are caused by similarities in surrounding particle fluctuating polarizations (a result of quantum dynamics).
Answer:
13
Explanation:
1 proton/neutron has an atomic mass of 1. We ignore the electrons because they are too small. Protons and Neutrons have the same atomic mass, therefore the answer s 6+7=13
Answer:
Explanation:
.65 M H₂SO₄
H₂SO₄ ⇄ 2H⁺ + SO₄⁻²
C(1-x) 2xC xC
(2xC)². xC /C( 1- x ) = 1.1 x 10⁻²
4 x³C² = 1.1 x 10⁻²
4 . x³ .65² = 1.1 x 10⁻²
x³ = .0065 = 6.5 x 10⁻³
x = 1.867 x 10⁻¹
H⁺ ion concentration =
2xC = 2 x 1.867 x 10⁻¹ x .65
= .2427
pH = - log ( .2427 )
= 0 .615 .
