Answer:
H3PO4 + 3NaOH ----> Na3PO4 + 3H2O
Explanation:
The balanced equation is given below
H3PO4 + 3NaOH ----> Na3PO4 + 3H2O
Its 100% B. my dude because the atomic theory doesn't state anything else
Answer:
The answer to your question is 194 g
Explanation:
Molecular mass is the sum of all the masses of the atoms that form a molecule.
In the problem, we have C₈H₁₀N₄O₂ which means
atomic mass number of atoms total
Carbon 12 8 12 x 8 = 96
Hydrogen 1 10 1 x 10 = 10
Nitrogen 14 4 14 x 4 = 56
Oxygen 16 2 16 x 2 = 32
194 g
Answer:
299.83°K
Explanation:
So, kelvin is a means of measuring temperature, as the question implies. To convert Celsius, one form of measuring temperature, to Kelvin, another form of measuring temperature, we must know the conversion median. Our median is that 0°C = 273.15°K. So, now, as we know that 0°C = 273.15°K, 26.68°C = 273.15°K + 26.68°. Because 273.15K might as well be zero degrees celsius (according to our median 0°C = 273.15°K), we simply add 26.68° to 273.15K and get 299.83°K
