<u>Answer:</u> The mass of oxygen reacted is
<u>Explanation:</u>
We are given:
Moles of propane = 9.98 mol
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of propane reacts with 5 moles of oxygen.
So, 9.98 moles of propane will react with = of oxygen.
To calculate the mass of carbon dioxide, we use the equation:
Moles of oxygen = 49.9 moles
Molar mass of oxygen gas = 32 g/mol
Putting values in above equation:
Hence, the mass of oxygen reacted is
<span>Hydrogen bonding between water molecules is the foundation of multiple properties of water such as cohesion, adhesion, surface tension, water's high specific heat, three states, and low freezing point which all contribute to water sustaining life. The three states of water coupled with the low freezing point allows organisms living in aquatic systems in cold climates to be protected from the freezing air temperatures by the layer of ice that forms across the surface of lakes and rivers. The high specific heat of water allows it to be a wonderful cooling agent for people, the water molecules can absorb large quantities of heat before evaporating of our skin when we sweat carrying the heat away as well. The cohesion and adhesion properties of water allow the tips of the tallest trees in the Amazon and Sequoia National Park to still receive water.</span>
Answer:
Question: The Haber-Bosch process involves the combination of nitrogen and hydrogen at high temperatures in the presence of a catalyst to produce ammonia. It is currently the main industrial source of ammonia.
Explanation:
Answer:
2.05 × 10²³ formula units
Explanation:
Given data:
Mass of AgF = 43.15 g
Number of formula units = ?
Solution:
Number of moles of AgF:
Number of moles = mass/ molar mass
Number of moles = 43.15 g/ 126.87 g/mol
Number of moles = 0.34 mol
Now Number of formula units will be determine by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number
1 mole = 6.022 × 10²³ formula units
0.34 mol × 6.022 × 10²³ formula units
2.05 × 10²³ formula units
