carbon dioxide is added to the atmosphere naturally when organisms respire or decompose,
Explanation:
Answer:
294 moles of P
Explanation:
For every 1 mol of P4O10 contains 4 mol of P
so;
73.5 mol P4O10 × <u> </u><u> </u><u> </u><u> </u><u> </u><u>4 mol P</u><u> </u><u> </u><u> </u><u> </u><u> </u>
1 mol P4O10
= 73.5 × 4
= 294 moles of P
Answer:
this option is correct the amount of heat required to turn a mole of a solid into a liquid
Option 4. ratio of electrons to protons
Isotope that has atomic number of 82 is stable. An element that has an atomic number ∠82 more stable except Tc and Pm. Also there is the concept that isotopes consisting a combination of even-even,even-odd,odd-even, and odd-odd are all stable. Many isotopes with no magic numbers of nucleons are stable
No, it is very unlikely for that to happen.
