Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3

The Yellow River is the most important water resource for the dry north of China, playing an irreplaceable role in economic development, and agriculture. Since 1960 over 14 dams have been constructed on the river for hydroelectric power, which is vital to northern China's infrastructure.
Answer:
The atomic mass of an atom is the number of protons plus neutrons.
Fact: In case you get it confused with atomic number, atomic number is the number of protons in the atom.
Explanation: It could have been electrons plus neutrons since electrons equals protons but electrons aren't stable which is why it is protons and neutrons.
Answer:
rate = k [H2O] [NO]²
Explanation:
[H2] (M) [NO] (M) Rate (M/s)
Trial 1 0.35 0.30 2.835 x 10-3
Trial 2 0.35 0.60 1.134 x 10-2
Trial 3 0.70 0.60 2.268 x 10-2
Comparing Trial 1 and 2 , the rate of the reaction increases by a factor of 4 when the concentration of NO was doubled. This means that the reaction is second order with respect to NO
Comparing Trial 2 and Trial 3, the rate of reaction increased by a factor of 2 when the concentration of H2O was doubled. This means that the reaction is first order with respect to H2O
The rate law fr the reaction is given as;
rate = k [H2O] [NO]²
