The chemical equation below shows the reaction between tin (sn) and hydrogen fluoride (hf). sn + 2hf snf2 + h2 the molar mass of hf is 20.01 g/mol. how many moles of sn are required to react with 40 g of hf? 1 2 3 4

1 mole

Explanation:

Moles of

Given mass= 40 g

Molar mass= 20.01 g/mol

Moles of

From the given balanced chemical equation, it can be seen that 2 moles of HF react with 1 mole of Sn.

Thus 1 mole of Sn are required to react with 40 g of HF.

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
