3 electrons are located in the 2p level
Well, 1st, you need to take the Fahrenheit temperature and subtract it from 32, make sure you put it in parentheses. Then, 2nd, you multiply it by it by 5/9. Here's an example of my explanation didn't make since:
T(°C) = (68°F - 32) × 5/9 = 20 °C
And that's how you convert Fahrenheit to Celsius temperatures.
Methane has the alkane functional group, so the name is composed of meth- for the carbon chain, and –ane for the alkane functional group
Answer:
Object 4 in the example
Explanation:
For simplicity and a clearer view of this problem, let's assume that four masses from 1 to 4 have the the masses 2 kg, 4 kg, 6 kg, 8 kg respectively.
According to the second Newton's law, we know that force is directly proportional to both mass and acceleration. The equation representing this is 
.
Notice that all of them have the same acceleration. This means, the greater the mass, the greater the force for a fixed acceleration. Simply speaking, the forces for each of the objects would be 2a, 4a, 6a and 8a respectively.
Since we're interested in the magnitude of the force and not direction, we neglect whether acceleration is positive or negative. This means that object 4 will require the greatest force to move, as it has the greatest mass.
Answer:
See explanation for details
Explanation:
6) C is false. What is going on there is actually a transformation of mechanical energy to the chemical energy stored in carbon dioxide in the atmosphere. The burning of the fossil fuel produces mechanical energy which is stored in the chemical bonds of CO2 hence the statement is false
7) A is true. Solar energy refers to energy from the sun, this energy is trapped from Tue sun and stored in chemical bonds in glucose, and starch molecules during photosynthesis.
8) C represents the release of carbon dioxide by the burning of fossil fuels.
9) B,C,D, E
B refers to photosynthesis in which plants take in atmospheric carbon dioxide
C refers to the burning of fossil rules which releases atmospheric carbon dioxide
D refers to the dissolution of atmospheric carbon dioxide in water bodies to form carbonates in water.
E refers refers the return of organic carbon to the soil by dead organisms
10) A and C
A shows the conversion of solar energy to chemical energy
C shows the conversion of mechanical energy to chemical energy
