___Zn (S )+___ HCl (AQ a) + return ___ZnCl2 (AQ a) + ___h2 It (g) STP in, H2, etc., not volume (g) 98g is the production of zinc from? Within 30 minutes as soon as possible .. Please explain your post, Otherwise, you'll be useless. I had a stomach disorder, 1.5 months, my chemistry teacher left me miss school, the T With a hat on my grades, I'm all class ...

Okay, first I need to balance the equation. There's one for the H2, and HCl in the other, so it is multiplied by the HCL 2 on each side of the 2 H Zhao said. Then, on each side of each element of Count the number of ... They are, so are you're okay. Zn + 2HCl yields ZnCl2 + H2, etc. Now we all know the mole ratio. 2 For the problem, we in the H2 zinc, and these two Coefficients are 1, the mole ratio of 1:01 means that now is the problem To start. H2 and the 98g of zinc, we have switched into the mole. So, The mass of the mass of our zinc, 65.4 g / Mall is a mall by a zinc 1.498 98g divided zinc. We multiply by the mole ratio of any 1:01 to get ... H2 and 1.498 mole. Now the volume should be such as H2. STP = NRT supplied to the PV, we (1atm) * (? L) = (1.498 Mall) * (ATM machines over 0.0821 Get in, drive-k) * (273.15 K). By any other pressure, and you .... 33.6 paebateul 1 ATM term) by the (right, multiply and divide
