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:
i think that the wet cloth will keep the coolness inside the water instead of evaporating and getting warm
Explanation:
Hand soap It’s a a basicccc
He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.
