Answer: because its more scientific and "formal"? I guess.
Explanation:
Which of the following chemical reactions produces water via a
synthesis reaction?
a 2H2 + O2 + 2H2O
b NaOH + HCI - NaCl + H2O
C CuO + H2 - Cu + H2O
d H2CO3 → CO2 + H2O
Answer:
Should be A, but also I think there should be an arrow between O2 and 2H2O
Finally, what mass of Na2HPO4 is required? Again, assume a 1.00 L volume buffer solution. Target pH = 7.49 Acid/Base pair: NaH2PO4 Na2HPO4 PK = 7.21 [Na2HPO4] > [NaH2PO4] (NaH2PO4) = 0.100 M 12.0 g NaH2PO4 required [base] [acid] = 1.91 [Na2HPO4) = 0.191 M. There is 1.00 L of solution. Use the molar mass of the base (141.95 g/mol)to find the mass required. Cubmit Answer Try Another Version 3 item attempts remaining

How many energy levels contain electrons in an atom of zirconium (Zr)?
The number of energy levels of zirconium is 5, and I know this because it is located in family five. Families are the rows across on the periodic table. The family number is always equal to the number of energy levels.Zirconium: properties of free atoms. Zirconium atoms have 40 electrons and the shell structure is 2.8.

Explanation:
C7H6O3+ C4H6O3=C9H8O4+H20
- Balance the above equation.
Answer:
2C7H6O3 + C4H6O3 - - - > 2C9H8O4 + H2O
Explanation:
Reactants:
2C7H6O3 + C4H6O3
C = 18
H = 18
O = 9
Products:
2C9H8O4 + H2O
C = 18
H = 18
O = 9
