Question

Someone please take a look at this and tell me if I'm right or wrong.

Write the formula unit equations
1) Iron reacts with hydrochloric acid to form aqueous iron (II) chloride and gaseous hydrogen.
my answer: Fe +HCl --> Fe(II) Cl + H

2) Chromium reacts with sulfuric acid to form aqueous chromium (III) sulfate and gaseous hydrogen

answer: Cr + H2SO4 --> Cr (II) SO4 + H

3) Tin reacts with concentrated nitric acid to form tin (IV) oxide, nitrogen dioxide and water.
my answer : Sn +HNO3 --> Sn (IV) O + NO2 + H2O

Answer 1

@EngrChong can you check my work? :)

Answer 2

4 ) Carbon reacts with hot concentrated nitric acid to form carbon dioxide, nitrogen dioxide, and water.
my answer is: C + HNO3 --> CO2 + NO2 + H2O

5) Sodium reacts with water to form aqueous sodium hydroxide and gaseous hydrogen.
my answer is: Na + H2O --> NaOH + H

Answer 3

thats just the 5

Answer 4

Your better than me

Answer 5

so you mean, I'm right ? is that a yes? :O

Answer 6

Wait let me ask a friend

Answer 7

thanks man :)

Answer 8

you first question: hydrogen gas is H2 not H.iron(II)chloride is Fe(II)Cl2.

Answer 9

chromium(III)sulfate is (Cr)2(SO4)3 and H2 is hydrogen gas.

Answer 10

Ohh I see

Answer 11

am i right @yamyam70 ?

Answer 12

are there more mistakes?

Answer 13

you can balance equations and i think if you write compound like this (FeCl2) is better than Fe(II)Cl and you can write state of compounds like (aq,s,g)

Answer 14

so , the terms aqueous, gaseous and s( don't know what s is) really affects the formula

Answer 15

s is solid. they are completeness. I hope my answer helped you.

Answer 16

and sorry if i answered late. english isn't my first language

Answer 17
