C. A central body is the center of the universe.
Answer:
B. Charges ( a slight positive charge on one end, and a slight negative charge on the other).
Answer:
if you tell me how much is needed and how much you have then i can answer it, but there is not enough information provided to answer to that question.
Explanation:
Answer:
0.57 moles (NH4)3PO4 (2 sig. figs.)
Explanation:
To quote, J.R.
"Note: liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.
H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O
Assuming that H3PO4 is not limiting, i.e. it is present in excess
1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"
Answer:
Chemical change
Explanation:
There are types of changes in nature namely: physical change and chemical change. A physical change is a change that does not alter the chemical composition of the substances involved, hence, no new substances are formed. On the other hand, a chemical change changes the chemical composition of the involved substances to form new substances.
Based on the definition of the types of changes below, the equation depicted in this question is a CHEMICAL CHANGE because it involves a rearrangement of the atoms of each element in the reactants to produce new sets of products with a new chemical formula.
C17H17ON3(s) + 2C4H6O3(l) → C21H21O5N(s) + 2C2H4O2(l)
