kcl is the salt koh is the base
You must react 5.3 g H_2 to produce 47 g H_2O.
<em>Step 1</em>. Calculate the <em>moles of H_2O</em>
Moles of H_2O = 47 g H_2O × (1 mol H_2O/18.02 g H_2O) =2.61 mol H_2O
<em>Step 2</em>. Calculate the <em>moles of H_2
</em>
Moles of H_2 = 2.61 mol H_2O × (2mol H_2/2 mol H_2O) = 2.61 mol H_2
<em>Step 3</em>. Calculate the <em>mass of H_2</em>
Mass of H_2 = 2.61 mol H_2 × (2.016 g H_2/1 mol H_2) = 5.3 g H_2
Answer:
Explanation:
<u>Given the following data;</u>
Initial volume = 400 mL
Final volume = 2000 mL
Initial pressure = 3 atm
To find the final pressure P2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
Answer:
d. solar winds
Explanation:
Dr. Tate and Dr. Ramirez are observing solar winds coming from the sun. Solar winds occurs naturally in which the particles such as electrons and photons releases from the surface of the sun into the space. These solar winds moves in the solar system and interact with planets of the solar system. Dr. Tate and Dr. Ramirez are the two well known scientist observing the effects of solar winds that has reached the planet Jupiter.
