Answer:
Na + CaSO4 = Na2SO4 + Ca
Explanation:
single displacement (substitution)
Explanation:
Small intestine.
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
Idk..if there is any other system that works....
Hope it helps really..
Answer:
Explanation:
Deal with 1 mole first.
The chemical formula of Magnesium Phosphate is
Mg3(PO4)2
The 2 tells you that there are 2 mols of Phosphorus in the chemical.
1 mol of anything is 6.02 * 10^23 (in this case) atoms.
2 mols of anything is 12.04 * 10^23 atoms
2 moles of anything is 1.204 * 10^24 (the 2 answers are the same. This one is more correct in scientific notation.)
Now we come to the 5.01. Where does that go?
5.01 * Mg3(PO4)2
So multiply 1.204 * 10^24 by 5.01 When you do, you get
7.26 * 10^24 atoms
Half reaction N_2 H_4 (aq) → N_2 (g)Balancing atoms except O and H N_2 H_4 (aq) → N_2 (g)Balancing charge N_2 H_4 (aq)→N_2 (g)+4H^+ (aq)Balanced half reaction for oxidation of hydrazine to gaseous nitrogen is N_2 H_4 (aq)→N_2 (g)+4 H^+ (aq)+ 4e^-
