Answer:
Bullet has more kinetic energy then baseball.
Explanation:
Mass of the bullet , m = 150 g = 0.150 kg
Velocity of the bullet = v = 440 m/s
Kinetic energy =
Kinetic energy of the bullet = K.E


Mass of the baseball, m' =
= 0.36146 kg
(1 ounce = 0.0283495 kg)
Velocity of the baseball= v' = 105.1 mph
1 mile = 1609.34 m
1 hour = 3600 seconds

Kinetic energy of the baseball = K.E'


14,520 Joules > 398.83 Joules
K.E > K.E'
Bullet has more kinetic energy then baseball.
Heat of combustion is a chemical property that can be measured.
Answer:
Assuming the product is AlCl3
Assuming its 1008 g of metalic Al
It will yeld 4234 g of aluminium chloride.
Explanation:
Al molar mass is 26.98 g/mol, so in 1008 g of Al there is 37.36 mols of Al
The stoichometry ratio between Al and AlCl3 is 1:1, so 37.36 mols of Al would form 37.36 mols of AlCl3 if the reaction were complete, but only 85% yelds, so 1008 g of Al makes up to 0.85x37.36 mols of AlCl3 (31.76 moles)
AlCl3 molar mas is 133.33 g/mol, so 31.76 moles has 4234 g
Hey there!:
Given % of Mn=59.1% means 59.1 g of Mn present in 100 g of manganese fluoride.
Molar mass of Mn= 54.938 g/mol
Moles of Mn = mass / molar mass
59.1 /54.938 => 1.07 ≈ 1 mol.
and % of F=40.9% means 40.9 g of of F present in 100 g of manganese fluoride.
Molar mass of F=18.998 g/mol
Moles of F :
40.9 / 18.999 => 2.15 mol ≈ 2 mol.
The mole ratio between Mn:F= 1 : 2
Therefore the empirical formula of manganese fluoride:
=> MnF2=Mn1F2
Hope that helps!
