Answer:
20 + CIPb
Explanation:
Use the commutateive proptery to reoder the terms
Answer:
0.26 ml
Explanation:
d = m/V
=> V = m/d = 15.2/58 = 0.26 ml
Answer:
2.16 MeV
Explanation:
To determine the amount of work done that is needed to assemble the atomic mass; we need to apply the equation;
U = 
where:
= proportionality constant = 
e = magnitude of the charge of each electron = 
r = length of each side of the vertex = 
So; replacing our values into above equation; we have:
U = 
U = 3.456 × 10 ⁻¹³ J
If we have to convert our unit from J to Mev; then we are going to have:
U = 3.456 × 10 ⁻¹³ J 
U = 2.16 MeV
Therefore, the amount of work done needed to assemble an atomic nucleus = 2.16 MeV
Answer:
The net ionic equation will be MgCl₂ + 2 NaOH → Mg(OH)₂ + 2 NaCl
Explanation:
Ionization of MgCl₂ is as follows
MgCl₂ → Mg²⁺ + 2 Cl⁻
Ionization of NaOH is as follows
NaOH → Na⁺ + OH⁻
It is a one type of substitution reaction where OH⁻ combined with Mg²⁺ to give magnesium hydroxide .
On the other hand Cl⁻ combined with Na⁺ to give sodium chloride as product.
Using proper stoichiometry to balanced the number of atoms in both side .
The reactants of the reaction will be solid gold (III) sulfide and hydrogen gas, while the products will be pure solid gold and hydrogen sulfide gas.
<h3>Chemical reactions</h3>
Reactants react together during reactions to arrive at products.
In this case, solid gold (III) sulfide and hydrogen gas react according to the following equation:

Reactants = solid gold (III) sulfide, hydrogen gas
Products: pure solid gold, hydrogen sulfide gas
