Answer:
2 electrons
Explanation:
The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons.
Answer:
d is the answer bc I know it is the answer
Yes because if it has different number of neutrons it could be a type of isotope
The percent yield : 81.5%
<h3>Further explanation</h3>
Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
2CO+O₂⇒2CO₂
mol CO(MW=28,01 g/mol)
mass CO₂ (theoretical)(MW=44,01 g/mol)
the percent yield :
<u>Answer:</u> The enthalpy of the reaction for given amount of ammonia will be -3431.3 kJ.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
<u>For ammonia:</u>
Given mass of ammonia =
Molar mass of ammonia = 17 g/mol
Putting values in above equation, we get:
We are given:
Moles of ammonia = 74.11 moles
For the given chemical reaction:
By Stoichiometry of the reaction:
If 2 moles of ammonia produces -92.6 kJ of energy.
Then, 74.11 moles of ammonia will produce = of energy.
Thus, the enthalpy of the reaction for given amount of ammonia will be -3431.3 kJ.
