Hydrogen gas has been suggested as a clean fuel because it produces only water vapor when it burns. If the reaction has a 88.9%

GaryK [48]

Answer:

Mass of hydrogen = 667 kg (Approx)

Explanation:

Given:

Mass of water = 593 kg

Yield rate = 88.9%

Find:

Mass of hydrogen

Computation:

Mass of hydrogen = [Mass of water / Yield rate]100

Mass of hydrogen = [593 / 88.9]100

Mass of hydrogen = 667.04162

Mass of hydrogen = 667 kg (Approx)

What is the most effective method for monitoring the effects of global warming?

balu736 [363]

Answer: D) Monitor the sea level over set period of time.

Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.

Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.

4 NH3 +5 02 +4NO + 6H2O When 70.25 grams of NH3 react, how many moles of H20 are produced?

romanna [79]

Answer:

6.19 mol H₂O

Explanation:

4 NH₃ + 5O₂ → 4NO + 6H₂O

First, we convert 70.25 grams of NH₃ into moles, using its molar mass:

70.25 g ÷ 17 g/mol = 4.13 mol NH₃

Then we convert 4.13 moles of NH₃ into moles of H₂O, using the stoichiometric coefficients of the balanced reaction:

4.13 mol NH₃ * $\frac{6molH_2O}{4molNH_3}$ = 6.19 mol H₂O

What is the mass of 3.2 moles of h2O ?

Arturiano [62]

Answer:

$\boxed{\text{57.7 g} }$

Explanation:

The first step is to calculate the molar mass of H₂O:

$\begin{array}{rcr}\text{2 H} & = & 2.02\\\text{1 O} & = & 16.00\\\text{TOTAL} & = & \mathbf{18.02}\\\end{array}$

So, 1 mol has a mass of 18.02 g.

Next you calculate the mass of 3.2 mol of H₂O

$\begin{array}{rcl}m & = & \text{3.2 mol H$_{2}$O} \times \dfrac{\text{18.02 g H$_{2}$O}}{\text{1 mol H$_{2}$O}}\\ & = &\boxed{\textbf{57.7 g H$_{2}$O}} \\\end{array}$
