Answer:- 168 moles of water are formed.
Solution:- The balanced equation for the formation of water from hydrogen and oxygen gases is:
From this equation hydrogen and oxygen react in 2:1 mol ratio.
We have been given with 178 moles of hydrogen and 84 moles of oxygen. We need to figure out the limiting reactant first. For this let's either calculate the moles of oxygen required to react completely with 178 moles of hydrogen or the moles of hydrogen required to react completely with 84 moles of oxygen.
Let's say we calculate the moles of oxygen required to react completely with 178 moles of hydrogen:
=
From the above calculations, 89 moles of oxygen are required to react completely with 178 moles of hydrogen but only 84 moles of oxygen are available, It means oxygen is the limiting reactant and the product yield depends on it.
There is 1:2 mol ratio between oxygen and water. Let's calculate the moles of water for given 84 moles of oxygen:
=
So, the reaction of 178 moles of hydrogen and 84 moles of oxygen gives 168 moles of water.

I'm just tryna get points I'm sorry
goodluck tho❤
Answer:
Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades, and improved operation and maintenance. On a global level, energy use can also be reduced by the stabilization of population growth.
Energy conservation is the key element of this policy because of its potential to reduce overall energy demand, costs, and consumption. ... It is often the most economical strategy to advance climate protection efforts and provides an environmentally safe alternative to increased energy production and consumption.
Here are 10 ways to converse energy:
Take advantage of a home energy audit.
Repair any electrical issues in the home.
Invest in energy-efficient appliances for the home.
Use power strips wherever possible.
Switch to LED light bulbs.
Set the water heater to the lowest comfortable setting.
Do laundry efficiently.
Explanation:
Answer:
224.28 g of W, are in 1.22 moles of it
Explanation:
This can be made by a rule of three:
1 mol of Tungsten (W) weighs 183.84 grams
1.22 mol of W, would weigh 224.28 g (1.22 . 183.84)
