Answer:
0.0077 moles KI
Explanation:
From the definition of Molarity (M) solve for moles, substitute and determine #moles. That is, Molarity (M) = moles solute/Liter solution => moles solute = Molarity(M) x Volume(L) = 0.0296M x 0.2586L = 0.0077 moles KI.
First of all, we convert the amount of item given in moles into grams. Each mol of steam is 18 grams of steam. Such that the heat released during the evolution of per gram of steam is,
H = (2.01 J/goC)(160 - 100) + 2260 J/g + (4.179 J/gC)(100 - 0) + (333.5 J/g) + (2.09 J/gC)(45oC)
H = 3226.05 J/g
Then, we multiply this value by 18 g to get the final answer which is equal to 58068.9 Joules.
answer: bits of rock rusting when exposed to oxygen and water
Explanation: i think because when it rains the water is left and freezes and night making the rock expand or start to Rust
Answer: The answer would be 6247.142 g
Explanation:
A bimolecular reaction typically takes twice as long as a unimolecular reaction. The answer is true
<h3>
How is activation energy related to temperature?</h3>
- Consider what must occur for ClNO2 to react with NO to understand why reactions have an activation energy.
- First and foremost, these two molecules must clash in order to organise the system.
- Not only must they be brought together, but they must also be kept in precisely the appropriate orientation relative to one other in order for the reaction to occur.
- Some energy must also be used in order to break the Cl-NO2 bond and allow the Cl-NO bond to form.
