One half of a balanced chemical equation is shown. 3mg(oh)2 + 2h3po4 which lists the numbers of each atom the other half of the equation would contain? a.) 3 mg, 2 p, 14 o, 12 h b.) mg, 2 p, 14 o, 6 h c.) 3 mg, 8 p, 7 o, 6 h d.) 6 mg, 6 p, 2 o, 12 h

3 Mg, 2 P, 14 O and 12 H

Explanation:

The relation between magnesium hydroxide and phosphoric acid is :

The number of each atom on both side of chemical equation must be same as per law of conservation of atoms.

No of Mg (magnesium) atoms are 3

No. of P (phosphorous) atoms are 2

No. of O (oxygen) atoms are 2 × 3 + 4 × 2 = 14

No. of H (hydrogen) atoms are 2 × 3 + 2 × 3 = 12

Hence, the correct option is (A) " 3 Mg, 2 P, 14 O, 12 H ".

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
