Question

I actually don't know what I'm suppose to be doing, can someone explain what I'm suppose to to do and/or the answers? Will answer with the Brainyist

Answer 1

blanks are for numbers:

2 HCl + 1 CaCO3 --> 1 CaCl2 + 1 H2O + 1 CO2

1 HNO3 + 1 NaHCO3 --> 1 NaNO2 + 1 H2O + 1 CO2

2 H2O + 1 O2 --> 2 H2O2

2 NaBr + 1 CaF2 --> 2 NaF + 1 CaBr2

1 H2SO4 + 2 NaNO2 --> 2 HNO2 + 1 Na2SO4

Edit: forgot to mention, this is called "balance the reaction equation" in chemistry.

Answer 2

Hey there.

I understand how hard this can be. So. . .What we are doing here is we are going to (Give the compound name for each compound. Your following will be there answers.

HCI compound name:
`\boxed{Hydrogen \ chloride}`

CaCo3 compound name:
`\boxed{Calcium \ carbonate}`

CaCl2 compound name:
`\boxed{Calcium \ chloride}`

H2O compound name:
`\boxed{Water}`

HN03 compound name:
`\boxed{Nitric \ acid}`

NAHCo3 compound name:
`\boxed{Sodium \ hydrogen \ carbonate}`

NaNo3 compound name:
`\boxed{Sodium \ Nitrate}`

o2 compound name:
`\boxed{Molecular \ Formula}`

H2o2 compound name:
`\boxed{hydrogen \ peroxide}`

NaBr compound name:
`\boxed{Sodium \ Bromide}`

CaF2 compound name:
`\boxed{Calcium \ difluoride}`

Naf compound name:
`\boxed{Sodium \ fluoride}`

Cabr2 compound name:
`\boxed{Calcium \ Bromide}`

H2so4 compound name:
`\boxed{Sulfuric \ acid}`

Nano2 compound name:
`\boxed{Sodium \ nitrite}`

HNo2 compound name:
`\boxed{Nitrous \ acid}`

NA2So4 compound name:
`\boxed{Sodium \ sulfate}`

Sorry, That took a very long time. It takes a while to box in my answers. I hope this could really help you.

Hope this helps.
