It'd be an endothermic reaction because it requires an input of heat to occur
Answer:
Explanation:
Hello,
In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:
Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:
Best regards.
Answer:
Molecular formula of aniline is C6H5NH2.
Explanation:
As we know, molecular mass can be calculated as
Molar mass = C6H5NH2
Molar mass = (6*12)+(1*7)+(28)
Molar mass = 93 g/mol
