Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.
Answer:- The substance is Propane and right choice is C.
Solution:- 10140000 J of heat is used to boil 28.47 kg at 298 K. Here, the important thing is, the liquid is changing to vapor and the temperature is not changing means it's a phase change. So, the formula used for this is:
where, q is the heat energy, m is mass and is the enthalpy of vaporization.
Let's rearrange the formula for as:
=
Let's plug in the values:
=
=
If we round this then it is . Hence, the right choice is C. propane.
