Answer:
mass of S₈ = 96.1146 grams
Explanation:
The balanced equation that describe the reaction is as follows:
8 Fe + S₈ ..............> 8 FeS
From the equation, we can note that:
8 moles of Fe react with 1 mole of S₈
This means that:
8 * 55.8 grams of iron react with 8 * 32 grams of S₈.
To know the mass of S₈ that will react with 167.6 grams of Fe, we will simply do cross multiplication as follows:
mass of S₈ = (167.6 * 8 * 32) / (8 * 55.8)
mass of S₈ = 96.1146 grams
Hope this helps :)
To solve this problem, we make use of the Faraday’s law
for Electrolysis. The formula is given as:
I t = m F / e
where the variables are,
I = current = 24.4 A
t = time = 46 min = 2760 s
m = mass produced = (unknown)
F = Faraday’s constant = 96500 C/equivalent
e = gram equivalent weight of gold
The gram equivalent weight is calculated by dividing the
molar mass with the amount of charge produced per atom. Gold has charge of 3+
therefore the gram equivalent weight is:
e = (196.97 g/mol)(1 mol/3 equivalents) = 65.66
g/equivalents
Solving for the mass m:
m = e I t / F
m = (65.66 g) (24.4 A) (2760 s) / (96500 C)
m = 45.82 g
<span>The correct answer should be Oak becaue of the climate. Spruces usually grow in places that are really cold, the more north you go the higher the chance of finding a spruce forest. South of it is usually an Oak forest because the climate is warmer and oaks grow in warmer climates that are not as harsh as those with spruces.</span>
Hey there!
Density = 2.67 g/cm³
volume = 30.5 mL
Mass = density *volume
Mass = 2.67 * 30.5
Mass = 81.435 g
Therefore:
Mass in kg :
1 kg -------------- 1000 g
?? ----------------- 81.435 g
mass = 81.435 * 1 / 1000
mass = 0.081435 kg
