Wich has more energy rolling down a hill - a bowling ball or soccer ball? Explain your answer
Answer:
Bowling ball
Explanation:
They are traveling at the same speed, but the bowling ball has more mass. The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.
Answer:
Explanation:
As a ball rolls downhill, its potential energy from its height is converted into kinetic energy of its motion. Potential energy is given by mass x gravity x height. So for the same height, a ball with higher mass will have more energy. A bowling ball is heavier than a soccer ball and will have more energy.

The Theory of Continental Drift says that the continents were once joined together and are drifting apart, Alfred Wegener is given credit for coming up with this theory.
What is continental drift?Continental drift is a kind of illusion in which it looks like that continents changes their places over the surface of the earth. The Theory of Continental Drift was given by Alfred Wegener, it is a hypothesis and according to this theory the continents will move with respect to the geological time relative to each other. And due to their movement on the non planar or dynamic geographical base it looks like a drift.

The molar mass of nitrogen (n2) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n2? 0.164 grams 6.09 grams 23.4 grams 129 grams
The mass in grams of 4.60 mol of nitrogen is 129g.
How we calculate mass from moles?Mass of any substance will be calculated by using their moles as:
n = W/M, where
W = required mass
M = molar mass
Given molar mass of nitrogen (N₂) = 28.02 g/mol
Given moles of nitrogen (N₂) = 4.60 mole
On putting these values on the above equation and calculated for W, we get
W = (4.60 mol)(28.02 g/mol)
W = 128.89g = 129g
Hence the required mass is 129g.

PLSSS HELP Which reaction is endothermic? *
2 points
HCl + NaOH → NaCl + H₂O + 58 kJ
2Na + Cl₂ → 2NaCl + energy
6CO₂ + 12H₂O + energy → C₆H₁₂O₆ + 6O₂ + 6H₂O
The last one is endothermic, as you can notice we are using up energy (absorbing energy) in order for the reaction to occur.
Whereas the other ones release energy, as they are considered exothermic.

A 0.770 M solution of potassium nitrate (KNO3) contains 1.75 mol of solute. Calculate the volume of the solution.
Stoichiometry can be used to determine the molality, molarity and volume of substances in a reaction.
What is concentration?
The term concentration refers to the amount of substance present in a solution.
1. Number of moles of NaCl = 142.8 g /52 gg/mol = 2.7 moles
Molarity = 2.7 moles/ 2.3 L = 1.17 M
2. 67.5 % of magnesium chloride implies 67.5 g of MgCl2 in 100 g of solution.
Number of moles of MgCl2 = 67.5 g/95 g/mol = 0.7 moles
molality = 0.7 moles/32.5 * 10^-3 = 21.5 m
3. Number of moles of the sugar = 62.5 g/342 g/mol = 0.18 moles
Number of moles of water = 250 g/18 g/mol = 13.9 moles
Since 1 g of water = 1 cm^3 water
Molarity = 0.18 moles/250 * 10^-3 = 0.72M
Molality = 0.18 moles/250 * 10^-3 = 0.72m
Mole fraction of sugar = 0.18/(0.18 + 13.9 ) = 0.01
Mole fraction of water = 13.9 /(0.18 + 13.9 ) = 0.99
4. A 48% solution of HCl contains 48 g of HCl in 100 g of water.
Number of moles of HCl = 48 g/36.5 g/mol = 1.3 moles
Number of moles of water = 52g/18 g/mol = 2.9 moles
Mole fraction of HCl = 1.3/(1.3 + 2.9) = 0.31
Mole fraction of water = 2.9/(1.3 + 2.9) =0.69

A container holds 500 mL of Co, at 742 torr. What will be the volume of the Co, if the
pressure is increased to 795 torr?
GIVEN
WORK
Answer:
V2 = 0.465
Explanation:
To solve this question, we need to follow the equation below:
P1V1 = P2V2
We know that:
V1 = 500ml = 0.5L (must be convert to L)
P1 = 742 torr (must be convert to atm by divided by 760) = 0.976 atm
P2 = 795 torr = 1.05 atm
V2 = ?
P1V1 = P2V2
0.976 x 0.5 = 1.05 x V2
0.488 = 1.05 x V2
(Divided by side by 1.05 to get rid of it)
V2 = 0.465
How many moles of ammonium nitrate are in 335 mL of 0.425 M NH4NO3?
Answer:
0.142
Explanation:
Answer:
0.142 moles.
You would have to convert the algorithm to a broken down version of the compound.
NH4NO3(aq] → NH+4(aq] + NO−3(aq]
The ammonium is removed for this case, concentration gets broken down to zero.
So here, if 1 liter is equal to 10 x 10 x 10 milliliters...
use the formula of n and c to help you figure out the moles.
C is equal to N divided by V, so in that case...
N equals C times V.
C times V is 0.425, or 17 over 40 in simplest form.
From there, multiply 17 over 40 by the current moles, cross out the liters, and multiply by 335, then, 10 to the power of -3. You have to flip it to negative, because it will cancel out either way. Change the equation by the liters, and you have 0.125
Hence, your correct answer is 0.125
