Both of them have high electronegativity. Hence they both tend to gain electrons to gain stability.
Answer:A
Explanation:
The solar system consist of the sun, the planets, stars and other objects. The chemical composition of the Sun consist mainly of Hydrogen and helium.
The sun is the largest object in the Solar system, it comprises nearly all the matter in the Solar System, Also the largest planet after the Sun are Jupiter and Saturn are giant planets forming almost the remaining matter of the solar system.
Like the Sun, the mass of Jupiter and Saturn are composed of roughly 98% hydrogen and helium with 2% of all the other elements combined.
Answer:
New volume V2 = 120.4 ml
Explanation:
Given:
Pressure P1 = 1.12 atm
New pressure P2 = 1.12[1+0.25] = 1.4 atm
Old volume V1 = 150.5 ml
Find:
New volume V2
Computation:
P1V1 = P2V2
(1.12)(150.5) = (1.4)(V2)
V2 = 120.4 ml
New volume V2 = 120.4 ml
Answer:
Option b. 9.59
Explanation:
First, let us calculate the pH. This is illustrated below:
[H3O+] = 3.9 x 10-5 M
pH = —Log [H3O+]
pH = —Log [3.9 x 10-5]
pH = 4.41
Recall: pH + pOH = 14
4.41 + pOH = 14
Collect like terms
pOH = 14 — 4.41
pOH = 9.59
False. This is a covalent bond. You can tell because it uses the prefix “hexa-“ you don’t use prefixes when it’s an ionic compound.
