If the hydrate gets too hot it could start splattering and cause a loss of sample.
Answer:
See explanation and image attached
Explanation:
The reaction between benzophenone and phenylmagnesium bromide is a Grignard reaction.
A Grignard reagent is any alkyl magnesium halide compound. In this case, the Grignard reagent is phenylmagnesium bromide.
Reaction of Grignard reagent with a ketone yields all alcohol. Thus, the reaction of benzophenone with phenylmagnesium bromide yields triphenyl methanol.
The mechanism of the reaction and all electron movements are shown in the image attached to this answer.

Answer: 59 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of hydrogen = 6.6 g
mass of oxygen = 52.4 g
Mass of products = Mass of hydrogen + mass of oxygen = 6.6 +52.4 = 59 g grams
Thus mass or reactant = mass of water
Mass of reactants = mass of products = 59 g
Thus the mass of water initially present was 59 g.
Answer:
As Per Given Information
Given mass of H₂O₂ ( Hydrogen Peroxide) 4.0 gm
We've been asked to find the number of moles in Hydrogen Peroxide .
First we calculate molecular mass of Hydrogen Peroxide .
Molecular mass of H₂O₂ = 1×2 + 16 × 2
Molecular mass of H₂O₂ = 2 + 32
Molecular mass of H₂O₂ = 34 gm
Now find the number of moles in given hydrogen peroxide .
Put the given value we obtain
So, the number of moles is 0.117 .
