Answer: Heat associated with the formation of 100.0 g of carbon dioxide is 1563.2 kJ.
Explanation:
Reaction equation will be as follows.
; 
= -11018 kJ
Mass of 
= 100 g
Hence, moles of present will be calculated as follows.
No. of moles = 
= 
= 2.27 mol
Therefore, heat produced by 2.27 mol for the given reaction will be calculated as follows.
= 1563.2 kJ
Thus, we can conclude that heat associated with the formation of 100.0 g of carbon dioxide is 1563.2 kJ.
A substance that readily burns
when it comes into contact with a flame has the chemical property of
reactivity. The answer is letter C. Reactivity is a chemical property of a
substance. According to EPA regulations, it is normally unstable and readily undergoes
violent change without detonating. it can explode or violently react when
exposed to water, when heated, or under STP.
Answer:
How much sunlight each flashlight gets (or doesn't get)
Explanation:
The independent variable is the variable that the investigator changes.
You are controlling the amount of sunlight each flashlight gets (or doesn't get).
B is wrong. The amount of decay is the dependent variable.
C is wrong. The type of plastic should be a controlled variable.
Cl2 has a molar mass of 71g/mole.
75g/71g/mole=1.06moles of cl2
2Na+Cl2→2NaCl
therefore, for every one mole of cl2 there are 2 moles of Na.
1.06*2=2.12moles of Na
every mole of Na is 22.98g
2.12moles *22.98g/mole= 48.72g Na
answer is 42.72grams
Molar Mass is the mass of a given substance, referring to the Atomic Weight of elements. Therefore, the Molar Mass of Iron (Fe) would be 55.845 gmol-1
