<span>Isotopes are atoms of the same element with the same number of protons and a different number of:
</span><span>c. neutrons.</span>
<span>523 grams
First, calculate the molar mass of CH3OH
Atomic weight of carbon = 12.0107
Atomic weight of hydrogen = 1.00794
Atomic weight of oxygen = 15.999
Molar mass of CH3OH = 12.0107 + 4 * 1.00794 + 15.999 = 32.04146
Now determine how many moles you have by dividing the number of atoms by avogadro's number
moles = 9.83 x 10^24 / 6.0221409 x 10^23 = 16.3231
Now multiply the number of moles by the molar mass
16.3231 * 32.04146 = 523.0159557
Since we only have 3 significant figures, round the result to 3 significant figures.
523.0159557 grams = 523 grams</span>
Answer: [tex]CO_2(s)\rightarrow CO_2(g)[/tex]
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
a) 
2 molesof gas are converting to 2 moles of another gas , thus is zero.
b) 
1 mole of solid is converting to 1 mole of liquid, the randomness increases and thus is positive.
b) 
2 moles of ions are converting to 1 mole of solid, the randomness decreases and thus is negative
d) 
1 mole of solid is converting to 1 mole of gas, the randomness increases drastically and thus is highly positive.
Answer:
Option (C). Write the complete balanced chemical equation.
Explanation:
Writing a balanced chemical equation is the key to arriving at the correct stoichiometric calculations because it gives a fore knowledge of the correct amount of reactants needed to generate a predicted products for a given reaction
