Answer:
A
Explanation:
because if you bond postitive and positive they would repell
Answer: 15.850
Explanation:
The conversion used from liters to gallons is:
1 L = 0.264172 gallon
The conversion used from sec to min is:
60 sec = 1 min
1 sec =
We are asked: liters/sec = gallons/min
Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.
4.2 × 10²² atoms Al × (1 mol Al / 6.022 × 10²³) = moles Al
Last one: fraction 1 mole Al over 6.022 × 10²³ atoms Al
Answer:
a) W = 820J, Q = 3314J =
b) For Path A ; ∆U= -2494J, ∆S = -8.85J/K
For Path B ; ∆U = -2494J, ∆S = -8.85J/K
Explanation:
The step by step and mathematical application is as shown in the attached files.
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.
