Answer:
a
Explanation:
it is an electrolyte because of its strong polar chemical bond
4 grams , mass cannot be created or destroyed. it has to be the same on both sides of the equation
Answer:
29.8 mg
Explanation:
Just slightly less than 1/2 decay
Answer:
2365.0 g
Explanation:
First we <u>convert 1.2 x 10²⁵ particles into moles</u>, using <em>Avogadro's number</em>:
- 1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol
Then we <u>convert 19.9 moles of NiCO₃ into grams</u>, using the <em>molar mass of NiCO₃</em>:
- NiCO₃ Molar Mass = 118.702 g/mol
- 19.9 mol * 118.702 g/mol = 2365.0 g
I believe this would be a chemical compound, yet it is not one of the options present.
