How would the will too small, or not affected? explain your answer a. b. in step 12 the ketone caught on fire and the filter paper was scorched in step 9 not enough magnesium was added to result in bubbles of h, c. 2. the % by weight of cu in a salt with one cu atom per formula unit is 33.9%. calculate the formula weight

The formula weight of the salt is 187.46 g/mol.

Explanation:

Let the formula weight of the salt = M

Number of copper atom per formula unit = 1

Atomic mass of copper = 63.55 g/mol

Percentage of copper in single formula unit = 33.9%

Percentage of an element in a compound:

M =187.46 g/mol

The formula weight of the salt is 187.46 g/mol.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
