N and ca can mix with each othe to make compound-explain
postnew [5]

Answer:

Yes, the formed product is calcium nitride, Ca_3N_2.

Explanation:

Hello,

In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

N_2+Ca\rightarrow Ca_3N_2

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.

Best regards.

grin007 [14]

Answer:

1 mole of P₄ consumed:4 moles of PBr₃ produced

Explanation:

Look at the coefficients in the balanced chemical equation to determine the ratios. For every 1 mole of P₄ consumed (P₄ has a coefficient of 1), 4 moles of PBr₃ would be produced (PBr₃ has a coefficient of 4).

The chance of their baby being blue is a 25% chance. There is a 50% chance that their baby will carry the trait but not have the feature. Since SpongeBob is heterozygus he carries the blue trait so his kid has a 50% chance of being blue from his genes. SpongeSusie is blue so she has a 100% of her child being blue.

So I am lost and I don't know how what any of those conversion factor things are and I'm wondering how to do #2,3, and 4. (I did
dalvyx [7]

Explanation:

#2.

A centigram is 1/100 of a gram, so that means a gram equals 100 centigrams.

Therefore you multiply 72.4 grams by 100/1 (or just 100), and get 7240 cg.

You did that one right but put the wrong unit in the answer. It is is cg ( centigrams).

#3.

1 liter is equal to 1000 milliliters, and I kiloliter is equal to 1000 liters. So one kiloliter is 1000*1000 milliliters or 1,000,000 milliliters.

The conversion factor would be

1/1000000

#4.

1 gigabyte is equal to 10^9 bytes.

I byte is equal to 10^9 bytes.

So 1 gigabyte is 10^9 * 10^9 nanobytes, or 10^18.

The conversion factor would be (1*10^18)/1.
