It is important because you wouldn’t want your immune system attacking cells that you need, and i think they tag the foreign cells, that way everytime it enters the body, its getting taken care of. I hope i help a little! I guess

<u>Answer:</u> The final volume of the reaction is 4.69 L

<u>Explanation:</u>

The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.

The equation used to calculate number of moles is given by:

\frac{V_1}{n_1}=\frac{V_2}{n_2}

where,

V_1\text{ and }n_1 are the initial volume and number of moles

V_2\text{ and }n_2 are the final volume and number of moles

We are given:

V_1=2.05L\\n_1=0.280mol\\V_2=?L\\n_2=0.641mol

Putting values in above equation, we get:

\frac{2.05}{0.280}=\frac{V_2}{0.641}\\\\V_2=\frac{2.05\times 0.641}{0.280}=4.69L

Hence, the final volume of the reaction is 4.69 L

How many grams of calcium phosphate are theoretically produced if we start with 552.2 grams of Ca(NO3)2 and 285.4 grams of Li3PO
Sedbober [7]
<span>molecular weight of Ca(NO3)2 --> 164 Ca=40 N=14 O=16 molecular weight of Li3PO4 --> 115.8 molecular weight of LiNO3 --> 68.9 Ca3(PO4)2 produced ---> 310.2 g/mol molecular weight Hence the answer would be 310.2 g/mol of calcium phosphate will be produced</span>

What basic equation is used to calculate the ph of a solution
Norma-Jean [14]

Answer: You can calculate the pH of an acid or base solution given the hydronium ion concentration by using the formula pH = -log [H3O+] or if given the hydroxide ion concentration by the formula [H3O+] = Kw / [OH-], then using the pH = -log [H3O+] formula.
