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.

<h3>Answer;</h3>
= 13.629 g of ZnCl2
<h3><u>Explanation;</u></h3>
The equation for the reaction.
Zn(s)+2HCL(aq)=>ZnCl2(aq)+H2(g)
Number of moles of Zinc;
Moles = mass/RAM
= 6.5 g/65g/mol
= 0.1 moles
The mole ration of Zn : ZnCl2 is 1 : 1
Therefore, number of moles of ZnCl2 is 0.1 moles
Mass = moles × Molar mass
= 0.1 ×136.286 g/mol
<u> = 13.629 g</u>
