A chemist determines by measurements that 0.0800 moles of bromine liquid participate in a chemical reaction. Calculate the mass

guajiro [1.7K]

Answer:

The mass of bromine liquid that participates in a chemical reaction=12.8 g

Explanation:

We are given that

Total number of moles of bromine liquid participate in chemical reaction=0.0800 moles

We have to find the mass of bromine liquid that participates.

Atomic mass of Br=79.9 g

1 mole of bromine liquid=2 atomic mass of bromine (Br)

1 mole of bromine liquid ( $Br_2$ ) = $2\times 79.9=159.8 g$

0.0800 moles of bromine liquid= $159.8\times 0.0800$ g

0.0800 moles of bromine liquid=12.784 g

0.0800 moles of bromine liquid $\approx 12.8$ g

Hence, the mass of bromine liquid that participates in a chemical reaction=12.8 g

Is melting sugar a chemical or physical change? Please provide an explanation

liraira [26]

Answer:

Hola Amigo! Here's Ur Answer :D

Explanation:

The chemical reaction we are most familiar with is that of melting: sugar decomposes at a temperature ranging between 184 and 186°C. This is a very recent discovery we owe to a team of researchers in Illinois. Basically, when we heat sucrose gently, this produces a phenomenon known as “ apparent melting ”.
