2. Ca10F2(PO4)6 + H2SO4 → Ca(H2PO4)2 + CaSO4 + HF

3. SiC + Cl2 → SiCl4 + C

4. NaCl + F2 → NaF + Cl2

5.Al + HCl → AlCl3 + H2

6.Ca3(PO4)2 + SiO2 → P4O10 + CaSiO3

7. C2H5OH + O2 → CO2 + H2O

What three natural resources are found in the great lakes region

Which part of earth’s surface receives the most direct rays from the sun? a) equator b) ocean c) poles d) mountains

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall. (use the words "first, second, third, fourth" to fill each blank)experimentinitial conc of a, mol/l initial conc of b, mol/l initial conc of c, mol/l initial rate, mol/l.s1 0.1 0.1 0.2 2 x 10-32 0.2 0.3 0.2 6 x 10-33 0.3 0.1 0.2 2 x 10-34 0.4 0.3 0.4 1.2 x 10-2
