Answer:
Zinc
Explanation:
The specific heat capacity can be described as the amount of heat required to raise the temperature of a substance by one degrees Celsius. It is represented by C or S. The greater the carrying capacity of a substance, the more will be the heat required for that substance.
As we can see in the information given in the question, the specific heat capacity of zinc is the lowest as compared to steel, water and aluminium. Hence, zinc is the correct option.
Molecular weight it stands for molecular weight
Answer:
The mass of water is 36 g.
Explanation:
Mass of hydrogen = 4 g
Mass of water = ?
Solution:
First of all we will write the balance chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen = mass / molar mass
Number of moles of hydrogen = 4 g/ 2 g/mol
Number of moles of hydrogen = 2 mol
Now we compare the moles of water with hydrogen from balance chemical equation.
H₂ : H₂O
2 : 2
Mass of water = moles × molar mass
Mass of water = 2 mol × 18 g/mol
Mass of water = 36 g
If the water oxygen is in excess than mass of water would be 36 g.
Obviously since plant cell contains chloroplasts.
Answer:
21091mg of aspirin the person need to consume
Explanation:
To solve this question we must find the mass of the person in kg. Knowing the lethal dose for aspirin is 400mg/kg of person, we can find the amount of aspirin that the person need to consume to get a lethal dose:
<em>Mass person:</em>
116lb * (1kg / 2.2lb) = 52.7kg
<em>Lethal dose:</em>
52.7kg * (400mg / kg) =
<h3>21091mg of aspirin the person need to consume</h3>
