One mole Hydrogen need 1/2mol O_2 .
Moles of Hydrogen
Moles of O_2
Answer:
NaI
Explanation:
Sodium has a charge of 1+ and iodine has a charge of 1-. They exist in a one-to-one ratio. Because they are ionic compounds, they go for the lowest ratio available.
Answer:
The least similar to a real gas found in the environment would be B.
Explanation:
Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.
Answer:
a. 6mL of ethanol and 35mL of water: the solute is ethanol (smallest volume) and the solvent is water (greater volume).
b. 300 g of water containing 8g of NaHCO3: the solute is NaHCO3 (smallest mass) and the solvent is water (greater mass).
c. 0.005L of CO2 and 2L of O2: the solute is CO2 (smallest volume) and the solvent is O2 (greater volume).
Explanation:
Hello there!
In this case, according to the given problem, it turns out possible for us to solve these questions by bearing to mind the fact that in a solution, we can find two substances, solute and solvent, whereas the former is in a smaller proportion in comparison to the latter; in such a way, we infer the following:
a. 6mL of ethanol and 35mL of water: the solute is ethanol (smallest volume) and the solvent is water (greater volume).
b. 300 g of water containing 8g of NaHCO3: the solute is NaHCO3 (smallest mass) and the solvent is water (greater mass).
c. 0.005L of CO2 and 2L of O2: the solute is CO2 (smallest volume) and the solvent is O2 (greater volume).
Regards!
