vazorg [7]3 years ago
5 0

Answer:

The answer to your question is: i have to answer correct first number three and second number one.

Explanation:

1.-regulate cell processes : Nucleic acids are located inside the nucleus and the nucleus is the brain of the cell, it says what functions must be done, then I think this option is correct.

2.- provide structure : Nucleic acids are large molecules but very weak, the couldn't be able to give structure. This option is wrong.

3.- transmit genetic information : The main function of nucleic acids is transmit genetic information, so this option is correct.

4.- fight disease: Nucleic acids are useful to transmit genetic information, and saying the functions a cell must do but fight against diseases is not one of their functions.

What is the gram formula mass of Ca3(PO4)2
Georgia [21]
Mass Molar of Ca_{3} (PO_4)_2
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of Ca_{3} (PO_4)_2 = 120 + 62 + 128 = 310 g/mol

Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?

III. For the following four sections: If you are given the formula, name the
serious [3.7K]

Answer:

15.Potassium oxide

16.Calcium chloride

17.Aluminium sulphide

18.CaS

Explanation:

15.K is the chemical symbol of Potassium and generally the name of the non-metal at the end of a formula has the suffix '-ide' and since O is oxygen, the name becomes Potassium oxide.

16. The same applies here. Ca is Calcium and Cl is Chlorine but since its the non-metal at the end, it ends in -ide. So Calcium chloride.

17.The same applies here too. Al is Aluminium and S is Sulphur so Aluminium sulphide.

18. Calcium's symbol is Ca and that of Sulphur is S and that gives the formula CaS.
