<span>To determine if changing the egg size affects the drop height. hope this helps</span>
I think the answer is 2Mg + H2O4 = Cu12O4 + 2H
I’m really not sure though so it might be wrong… I’m not the best at balancing equations lol
Answer:
2.13atm
Explanation:
The following information were obtained from the question:
P1 (initial pressure) = 2atm
T1 (initial temperature) = 27°C = 27 + 273 = 300K
T2 (final temperature) = 47°C = 47 + 273 = 320K
P2 (final pressure) =?
Using the equation P1/T1 = P2/T2, the final pressure within the tyre can be obtained as illustrated below:
P1/T1 = P2/T2
2/300 = P2/320
Cross multiply to express in linear form
300 x P2 = 2 x 320
Divide both side by 300
P2 = (2 x 320)/300
P2 = 2.13atm
Therefore, the pressure within the tyre at 47°C is 2.13atm
33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.
<h3>HOW TO CALCULATE MASS?</h3>
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
However, the number of moles of magnesium hydroxide must be calculated by dividing the formula units by Avogadro's number.
no. of moles = 3.421 X 10²⁶ ÷ 6.02 × 10²³
no. of moles = 0.57 × 10³
no. of moles = 5.7 × 10²moles
Molar mass of Mg(OH)2 = 24 + 34 = 58g/mol
mass of Mg(OH)2 = 570 moles × 58g/mol
mass of Mg(OH)2 = 33060g
Therefore, 33060 grams of magnesium nitrate would be produced from with 3.421 X 10²⁶ formula units of magnesium hydroxide.
