I won't give you the answer, but I will give you the process and then you can plug in the numbers. I'm guessing you are looking for how many MOLES are in 63.658g of Carbon. What you need to do to solve this is to use the molar mass of Carbon plugged into the dimensional analysis process. That might sound confusing, so let me give you a sample question.
Now, you plug in the numbers in your problem into that sample process. And if you don't know where to find the molar mass, it's simple.
The Molar mass of an element is the same as the atomic mass. So Hydrogen has the atomic mass of 1.01u, and it also has the molar mass of 1.01 grams per mole.
Answer:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
Explanation:
Answer:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them.
Explanation:
H = mCpT
H = (500 grams water)( 4.18 J/ g - degrees C) (65 - 50)
H =31,350 J
since 1 cal = 4184 joules
31,350 Joules (1 calorie/ 4184 joules) = 7.49 calories
Answer:
A balanced chemical equation not only describes some of the chemical properties of substances—by showing us what substances react with what other substances to make what products—but also shows numerical relationships between the reactants and the products.
(2) 2-chloropropane (4) 2-pentene
Answer: Both technicians are correct
Explanation: A chemical tester and exhaust gas analyzer are two important ways to check for gasket leakage
G. Does the material feel hard to the touch?
H. Will the material float in water?
J. Does the material feel rough or smooth?
Answer:
i think the answer is f as metals are malleable and ductile
Answer:
F
Explanation: Most metals carry the trait that they are malleable and ductile.
