242 g/mol...... hope it helps :)
Answer:
The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat.
They’re going to increase in atomic size based on how many electrons they have. You should be able to look at a periodic table or just look up how many electrons each of them has and then you can put it in that order
The theoretical mass of
is 110.
<u>Explanation:</u>
Mass of one atom of calcium = 40 .
Mass of one atom of chlorine=35.5 .
Hence , two atoms would be 
Therefore, mass of calcium chloride would be net sum both constituent atoms
= 
So the theoretical mass of
is 110.
The theoretical mass is the measure of item coming about because of an ideal chemical reaction, and in this manner not equivalent to the sum you'll really get from a response in the lab. It is the measure of item coming about because of an ideal chemical reaction, and therefore not equivalent to the sum you'll really get from a response in the lab.
