Due in 30 MINUTES! A single-replacement reaction of zinc and hydrochloric acid occurs.

Zn + 2HCl → ZnCl2 + H2
If 2.5 moles of HCl react with excess Zn, how many moles of H2 will be produced?

What is the formula that this ionic compounds could form sr2+p3-o2-

All cells are made of four types of acids, lipids, proteins, and carbohydrates.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
