Answer:

The answer is c) 1e-

Explanation:

The chemical change is the loss of 1 electron (1 e-) in 1 atom of sodium (Na) to give a sodium cation (Na⁺). You have to put the electron in the cation side of the equation. In this way, the overall process is electrically neutral (1 positive charge is neutralized by 1 negative charge and the other side has not charges):

Na → Na⁺ + 1 e-

Consider the ionic compound that is the combination of the Chromium (III) and hydroxide ions. How many chromium atoms would be p
kobusy [5.1K]

An ionic compound forms when a metal bonds with a non-metallic element. Metals usually form the cation and non-metal anions. Chromium has an oxidation number of +3 in the compound and charge on hydroxide ion is -1.

Cation here is Cr^{3+}

Anion is the hydroxide ion OH^{-}

So the formula of the compound will be: Cr(OH)_{3}. The compound has one chromium atom and two hydroxide ions.

Therefore, there will be one Chromium atom per each chromium hydroxide compound.

If a diatomic molecule has a vibrational force constant of k=240 kg s-2 and a reduced mass of 1.627x10-27 kg, its vibrational fr
asambeis [7]

Answer:

2040 cm-1

Explanation:

The vibrations frequency is obtained from;

v=1/2πc √k/μ

Where;

k= force constant = 240kgs-2

μ= reduced mass = 1.627×10^-27 kg

c= speed of light= 3×10^10cms-1

v= 1/2×3.142×3×10^10√240/1.627×10^-27

v= 5.3×10^-12 × 3.84×10^14

v= 20.4×10^2

v= 2040 cm-1

What is the acceleration due to gravity of the moon<br>​
sashaice [31]

Answer:

Earth's average surface gravity is about 9.8 meters per second per second. When an object is tossed off a building top or a cliff apex, for instance, it accelerates toward the ground at 9.8 meters per second per second. The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second per second,
