What do mass and weight have in common?
Answer:
Mass is a measure of how much matter an object contains, while weight is a measure of the force of gravity on the object. An object has the same composition, and therefore mass, regardless of its location.

What is the process called that living things perform to make useable energy from
sugar?
-photosynthesis
-exercise
-heterotrophs
-cellular Respiration
Answer:
cellular respiration
Explanation:
Organisms ingest large molecules, like carbohydrates, proteins, and fats, and convert them into smaller molecules like carbon dioxide and water. This process is called cellular respiration, a form of catabolism, and makes energy available for the cell to use.

. Name three types of energy that exist in a large piece of charcoal on a grill in the sunlight. Explain why the charcoal has each type of energy. (3 points)
Answer:
Chemical Energy, Heat Energy, Radiant(Solar) Energy
Explanation:
First of all, in the large piece of charcoal, there is Chemical energy is stored in it's hydrocarbon molecules. Now, when the charcoal is placed under the grill, it is combusted and then the chemical energy is transformed into heat energy.
Also since it's exposed under sunlight, the charcoal will experience the effect of radiant(solar) energy.

How many hours are in 7 months? (assume 30 days in a month)
Answer:
there is about 5110.01 hours in 7 months
Explanation:
because no 7 months in a row have the same amount of months so about 730.001428571 days in 7 months times the number of months. Hope this helps!
Answer: 730.08 hours x 7= will get you your answer
Explanation: Because, the average month is 30.42 days. A day is 24 hours, so the average month is 730.08 hours ( 30.42 days * 24 hours ). Just do the math above and that should be your answer.

How many moles of gold (Au) are there in 3.01 X 10^23 atoms of gold (Au)?
are sand and water a heterogeneous or homogeneous
Answer:
Salt is soluble in water, which would give a homogeneous mixture. But, when you add sand, which is insoluble, you will have a mixture of two different phases, a solid and a liquid, therefore this is a heterogenous mixture.
Explanation:

if 125g of KClO3 is heated, what is the total mass of the products?
Given parameters:
Mass of KClO₃ = 125g
Unknown:
Total mass of the products = ?
When KClO₃ is heated, it thermally decomposes to KCl and O₂ according to the chemical equation below;
2KClO₃ → 2KCl + 3O₂
All chemical equations obeys the law of conservation of matter and with this regard, we know that the amount of reactants used is the same as that of the product.
The total mass of the products must give us 125g according to this law of conservation of matter.
Now to find the masses of each product,
Find the number of moles of the given reactant:Number of moles = [tex]\frac{mass}{molar mass}[/tex]
molar mass of KClO₃ = 39 + 35.5 + 3(16) = 122.5g/mol
So number of moles of KClO₃ = [tex]\frac{125}{122.5}[/tex] = 1.02moles
2. Now, using this number of moles, find the number of moles of the products using this value;
2 moles of KClO₃ produced 2 moles of KCl
1.02 moles of KClO₃ will also produce 1.02moles of KCl
2 moles of KClO₃ produced 3 moles of O₂
1.02 moles of KClO₃ will produce [tex]\frac{1.02 x 3} {2}[/tex] mole = 1.53 moles of O₂
3. Now find the masses of each product;
Mass = number of moles x molar mass
molar mass of KCl = 39 + 35.5 = 74.5g/mol
molar mass of O₂ = 16 x 2 = 32g/mol
Mass of KCl = 74.5 x 1.02 = 75.99g
Mass of O₂ = 32 x 1.53 = 48.96g
Total mass of products = mass of KCl + Mass of O₂ = 75.99g + 48.96g
= 124.95g
This value is approximately the same as that of mass of KClO₃
Is Salt and pepper an example of a homogenous mixture?
Answer:
no it is a heterogeneous mixture because salt and pepper are not mixed uniformly.
L is the midpoint of VC
LV = 9 find VC
Answer:
VC = 18
Explanation:
Since L is the midpoint and you have LV, you know that LC is also 9.
When a force sets an object in motion, the moving object has kinetic energy.
True or false
Answer:
I think it's true but I'm not to positive on it <3
Explanation:
Answer: True
Remember, Kinetic Energy is anything that moves and not that stops. Let’s make something up, Steve is playing Jacks.When Steve bounces the ball it has kinetic energy when he releases it from his hand, when the ball hits the ground it’s called Potential Energy because it stops.

how objects with different masses and volumes have the same density?
Answer:
mass and volume are independent. Two objects with the same volume can have different masses hence they can have different densities

What is the definition of a Lewis acid?
a substance that accepts electrons to form a covalent bond
a substance that donates electrons to form a covalent bond
a substance that accepts a proton
a substance that donates a proton
Lewis acid is:
A. a substance that accepts electrons to form a covalent bond
What is a Lewis acid?A Lewis acid is accordingly any substance, for example, the H+ particle, that can acknowledge a couple of nonbonding electrons. At the end of the day, a Lewis acid is an electron-pair acceptor.
Thus, option A is correct.
