Answer:
the correct answer is E
Explanation:
None of the options is correct, because entropy is the thermodynamic magnitude that indicates the degree of molecular disorder of a system, in exothermic processes energy or heat is released to the medium and energy is taken from the medium in endothermic processes, entropy if it depends of the temperature since the temperature is what sometimes determines if the process is spontaneous or not, and the delta universe in spontaneous processes is not always greater than zero, it is more frequently less than zero with negative values.
Answer:
it natural gas or fossil fuels
Hey there!:
Molar mass CO2 = 44.01 g/mol
44.01 g CO2 ------------------- 6.02*10²² molecules CO2
88 g CO2 ------------------------ y
y = 88 * ( 6.02*10²² ) / 44.01
y = 5.29*10²⁵ / 44.01
y = 1.2 * 10²⁴ molecules of CO2
Answer A
Hope that helps!
Answer:
7.208 g
Explanation:
0.4mol x 
= 7.208 g
You are using molar mass of H20 to find the mass. Moles of 0.4 and 1 mol cancel out leaving you with just grams. You get the values in the numerator from the periodic table and the 2(1.01) is because you have 2 of the H in H20
