Answer:
149.6 grams
Explanation:
Mass in gram = molar mass * number of moles
Massof CO2 in gram = 44*3.4=149.6 grams
Answer:
Scientific Explanation of weather change and cause storms is described below in detail.
Explanation:
The weather is just the nature of the environment at any time, including items such as warmth, rainfall, air pressure, and cloud shelter. Daily variations in the weather are due to storms and winds. Seasonal variations are due to the Earth spinning nearby the sun. Warm beginnings often produce stormy weather as the heated air mass at the exterior rises above the cool air mass, creating clouds and storms.
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.
2. They all have 1 valence electron, they form ions with a +1 charge.
3. cation
4. Lithium, Li
5. Francium, Fr
6. Cesium has a melting point of 28.5 C so I’m assuming that’s the correct answer, Francium is radioactive
7. Sodium, Rubidium, Lithium, and Cesium are all soft metals that can be cut with a knife.
