1) ionic compound
there should be motive ions or free movable electrons to conduct electricity. The ionic compounds in the solid state, has no motive ions or free electrons as the ions are tightly attracted to each other. But in liquid state, the ions separate and move freely.
Answer:
1.54grams
Explanation:
Molarity of a solution = n/V
Where;
n = number of moles (mol)
V = volume (L)
Based on the information given in this question;
Volume of NaOH solution = 5.0 × 10ml
= 50ml = 50/1000 = 0.050 L
Molarity = 0. 77 M
Using; Molarity = n/V
0.77 = n/0.05
n = 0.77 × 0.05
n = 0.0385mol
To find the mass (grams) of NaOH in the solution, we use the following formula:
mole (n) = mass/molar mass
Molar mass of NaOH = 23 + 1 + 16 = 40g/mol
0.0385 = mass/40
mass = 0.0385 × 40
mass = 1.54grams.
The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.
<h3>What is radioactivity?</h3>
Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.
The radioactive particles that are usually emitted include:
- alpha particles
- beta particles and
- neutrons
The neutron has a mass of 1.
When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.

The plants will die and decay because they have no oxygen and plants will block sunlight to deeper water
Sulfuric acid (H2SO4) is a strong acid which should be neutralized with a base. Ideally, sodium bicarbonate (NaHCO3) is used to treat acid spills. The reaction is as follows:
H2SO4 + 2NaHCO3 → Na2SO4 + 2H2O + 2CO2
Bubbles will be formed as CO2 is released. Once all H2SO4 has been neutralized the bubbles will stop. The pH of the spill after neutralization can be checked with a pH and should be between 6-9. If optimal pH is observed the waste can be disposed into a proper container and the work station can be cleaned with a paper towel.
