Inorganic compounds make ionic bonds.
Sodium Chloride or NaCl is a ionic bond
Answer:
After 4 days 10 g will left
After 8 days 5 g will left.
Explanation:
Given data:
Half life of isotope = 4 days
Total amount of sample = 20 g
Amount left after each time period = ?
Solution:
The half life of radioactive isotope is 4 days it means after 4 days the amount left will be half of total amount.
20 g/2 = 10 g
The half amount which is left will be consume in next 4 days and remaining amount will be,
10 g/2 = 5 g
After 4 days 10 g will left
After 8 days 5 g will left.
I’m pretty sure the answer is stir the water
Answer:
B) conducts electricity
Explanation:
Metals are conductors, literally meaning they conduct electricity.
One metal is liquid at room temp (there might be one more but I only know of mercury).
The reactivity depends on the placement in the periodic table.
If it conducts electricity, it can't be an insulator.
