How many grams are in 3.00 moles of carbon
Answers
Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨
Explanation:
There are 36 grams in 3.00 moles of carbon.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;mass (g) = no. of moles (mol) × molar mass (g/mol)According to this question, 3 moles of carbon was given. The mass can be calculated as follows:atomic mass of Carbon = 12g/molMass = 12g/mol × 3molMass = 36g. Therefore, there are 36 grams in 3.00 moles of carbon.Learn more at: https://brainly.com/question/15743584?referrer=searchResults

High-speed winds transfer more energy to the ocean’s surface, creating bigger waves.
Question 10 options:
True
False
Answers
Answer:
I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing
Answer: True.
Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.

An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will happen to it's temperature?
a. It will halve to T/2.
b. It will increase to 3T.
c. It will increase to 2T.
d. It will remain the same.
Answers
Answer:
It will be halve of T
Explanation:
V1 = V
T1 = T
V2 = ½V
T2 = x
V1/T1 = V2/T2
V/T = ½V/x
Vx = ½VT
2Vx = VT
2x = T
x = ½T

1. 0.488M
2. 7.67mol
3. 7.67M
4. 0.000767M
Answers
Answer:
7.67
Explanation:
According to molar concentration, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.
What is molar concentration?Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution of values in the given formula gives, molarity= 22.41/58.44×1/0.05=7.67 M.
Thus, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.

moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole
Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams
%Yield = Actual Yield/Theoretical Yield x 100%
= 18.5g/20.963g x 100% = 88.25%

When magnesium is added to hydrochloric acid, a gas is formed. Explain what happens in the reaction, how the gas is collected and how it could be tested to prove what it is.
Answers
Answer:
Explained below.
Explanation:
Formula when magnesium reacts with hydrochloric acid is given by;
Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)
So, from the equation, we can see that the gas formed is hydrogen.
This hydrogen gas is collected by a method known as water displacement.
This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
