Chemistry
1 answer:
Dominik [7]3 years ago
3 0

Answer:

C

Explanation:

Calcium is an element with a total of 20 electrons.

 It has 4 shells with a configuration of:

          2, 8, 8, 2

Option C is the most similar to calcium but the number of shells is not complete.

It still requires two more shells with 8 and two electrons respectively.

A compound with the empirical formula ch2 has a molar mass of 98 g/mol what is the molecular formula for this compound ?
madam [21]
Approximate molecular masses:
Molecular mass of C = 12
Molecular mass of H = 1

Let n = moles required for CH₂.
Then
nCH₂ = 98
n(12 + 2*1) = 98
14n = 98
n = 7

Answer: The molecular formula is 7CH₂

The definition of heat transfer through convection involves the movement of a fluid that causes heat to move away from a hear source. That being said, convection can take place in a lake, air inside, and air outside since both liquids and gasses are considered to be fluids. I hope this helps. Let me know if anything is unclear.
