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.
<span>The
immediate destructive action of a nuclear explosion is caused by shock. The answer
is letter D. The shock wave cause an instantaneous jump in pressure at the
schock front. The combination of the pressure produced in the front and the
jump causes the damage.</span>
Answer:
1528.3L
Explanation:
To solve this problem we should know this formula:
V₁ / T₁ = V₂ / T₂
We must convert the values of T° to Absolute T° (T° in K)
21°C + 273 = 294K
70°C + 273 = 343K
Now we can replace the data
1310L / 294K = V₂ / 343K
V₂ = (1310L / 294K) . 343K → 1528.3L
If the pressure keeps on constant, volume is modified directly proportional to absolute temperature. As T° has increased, the volume increased too
The balanced reaction is
2CH3OH (g) + 3O2 (g) ⟶ 2CO2 (g) + 4H2O (g)
as per equation two moles of methanol gas will react with 3 moles of oxygen
one mole of gas occupies 22.4 L of volume
so the moles and volume goes in same ratio
it means two unit volume of methanol will react with three unit volume of oxygen
therefore 1L of methanol gas will react with 3 /2 L of oxygen
Or 18 L of methanol gas will react with 3 x 18 /2 = 27 L of oxygen
So here oxygen is limiting reagent
As per balanced equation
10L of oxygen will react with = 2 X 10 /3 L of methanol = 6.67 L of methanol gas to give 6.67 L of CO2 gas and 13.33 L of water gas
So overall there will be = 18 - 6.67 L of left out methanol = 11.33 L
And 6.67 L of CO2 + 13.33 L of water = 20 L
Total volume of gas = 11.33+ 20 = 31.33 L
When water molecules align with each other, a weak bond is established between the negatively charged oxygen atom<span> of one water molecule and the positively charged </span>hydrogen atoms<span> of a neighboring water molecule. The weak bond that often forms between </span>hydrogen atoms<span> and neighboring atoms is the hydrogen bond.</span>
