These methods are:
Observation ----- Hypothesis --------- Theory ------------ Law
A hypothesis is a scientific explanation to an observation. It provides a platform for carrying out experiments to test ideas and to see how repeatable an observation can be.
The answer is covalent bond!
Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Answer:
14g
Explanation:
assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles
then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass
so, 0.5 x 28 = 14g
