Identify what type of reaction each of the following is - synthesis (S), decomposition (D), combustion (C), single-displacement (SD), or double-displacement (DD). Note: one of the
problems below is NOT a chemical change - it is physical!
1.
NaCl + H2SO4 → Na2SO4 + HCI
6.
Al(OH)3 + HC2H302 → Al(C2H302)3 + HOH
C2H5SH + O2 + CO2 + H20 + SO2 7.
C6H12O6 + O2 → CO2 + H2O

.
3.
Ni(CIO3)2 → NiCl2 + O2
8.
Cd3(PO4)2 + (NH4)2S → CdS + (NH4)3PO4
4.
P205 + H2O → H3PO4
9.
CO2 (s) → CO2 (g)
5.

10.
HNO3 → N205 + H2O

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry

About 70 percent of the earth's surface is water-covered, and about 96.5 percent of all earth's water is salt water. identify the watery feature on earth that is made of freshwater rather than salt water. a) bay b) glacier c) ocean d) sea it is not incomplete this is the true question

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
