Magnesium plays a vital role in the function and structure of the body.
The adult human body consist of 25 grams of magnesium i.e. 0.25 % of the human body composition approximately.
Therefore, for a 60 kg adult, then the amount of magnesium in their body would be
= 0.15 kg
Convert kg to g:
1 kg = 1000 g
So, 0.15 kg = 
= 150 grams
Thus, amount of magnesium in 60 kg adult is equal to 150 grams
Hello!! My answer would be that they should add the solar panels that faces the south. Since the sun rises in the east and sets in the west, the south portion would get both sunlight from the east and west sides. I hope this helps!!
Answer:
1 mole ozone gas
Explanation:
Since atomicity of Ozone (3) is maximum so, it will contain maximum number of atoms.
Answer:
b) The total moles of each element present in the reactants and in the products.
Explanation:
Hello there!
In this case, since the law of conservation of mass is used to realize that the mass, atoms and molecules of all the species involved in a chemical reaction must be the same at both reactants and products, we can see that a and c stand for those that must be equal; thus, we infer that the moles can be different as they stand for the amount of substance which is related to the mass via molar masses. Therefore, the answer would be b) The total moles of each element present in the reactants and in the products.

Answer:
Her acceleration was 0.8 m/s².
Explanation:
Given data:
Final speed v₂ = 5.4 m/s
Initial speed v₁= 3.0 m/s
Initial time t₁ = 2 s
Final time t₂ = 5 s
Acceleration = ?
Solution:
acceleration = (v₂- v₁) / (t₂ - t₁)
acceleration = 5.4 - 3 / 5-2
acceleration = 2.4 / 3 = 0.8 m/s²
