Answer:
16Ag + 2C2 ---> 4 Ag4C
Explanation:
Ag + C2 ----> AgC2
The valence of Ag is one
Valence of Carbon is four
A balanced equation would be
16Ag + 2C2 ---> 4 Ag4C
Group 6 elements usually have extra electrons to make give them an octet. So, they have 6 electrons to start and when they have an octet, they have 8.
We can find the charge by doing simple math 6 - 8 = -2
Answer is D)
2K + Br2 ===> 2KBr
It's very ionic. The transfer of 2 electrons from K to Br2 is nearly as complete as it can be.
Answer:
0.12 mL of the epinephrine solution.
Explanation:
We have:
A bottle of epinephrine labeled 1 mg in 1 mL of solution,
We need to prepare:
An injection of 0.12 mg of epinephrine
Hence:
Therefore, to prepare an injection of 0.12 mg of epinephrine labeled 1 mg in 1 mL we need to inject 0.12 mL of the epinephrine solution.
I hope it helps you!
Answer:
Explanation: As with any substance, oxygen takes up much less space as a liquid than it does as a gas, so engineers can fit more oxygen into the same tank.
