Science help

[Lord Bowser]

So I got this assignment in science where we have to balance chemical equations, and there are two that I want to confirm that I'm right about before I turn it in. Please correct me if I'm wrong.

The first one I had to balance was...
Na3PO4 + Ba(NO3)2 ------> Ba(PO4)2 + NaNO3
...and that I said was impossible because no matter what I did, I'd always end up with too many or too few oxygen atoms. The teacher himself said he might've typed it wrong.

The second one I had to balance was...
H3AsO4 + Pb(NO3)2 ------> HNO3 + PbHAsO4
...and I got this answer;
3H3AsO4 + 3Pb(NO3)2 ------> 6HNO3 + 3PbHAsO4

All help is appreciated, and thank you in advance!

you couldn't do the first one because it was missing the correct number of Barium atoms in Barium Phosphate

the last one can be simplified

Spoiler: answers if you can't be stuffed

2Na3PO4 + 3Ba(NO3)2 ------> Ba3(PO4)2 + 6NaNO3

H3AsO4 + Pb(NO3)2 ------> 2HNO3 + PbHAsO4

I knew the first one was written wrong! Thanks so much for helping me; I'll simplify the oher one too.

no problem, funny enough we were balancing chemical equations in Chem today lol

Isn't chemistry a high school class? If so, it's kind of weird that an 8th grade non-Honors class is doing this already...

We did this earlier this year.
