Explanation:
Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.
Answer:
85.34g of NH3
Explanation:
Step 1:
The balanced equation for the reaction. This is given below:
N2 + 3H2 —> 2NH3
Step 2:
Determination of the number of moles of NH3 produced by the reaction of 2.51 moles of N2. This is illustrated below:
From the balanced equation above,
1 mole of N2 reacted to produce 2 moles of NH3.
Therefore, 2.51 moles of N2 will react to produce = (2.51 x 2)/1 = 5.02 moles of NH3.
Therefore, 5.02 moles of NH3 is produced from the reaction.
Step 3:
Conversion of 5.02 moles of NH3 to grams. This is illustrated below:
Molar mass of NH3 = 14 + (3x1) = 17g/mol
Number of mole of NH3 = 5.02 moles
Mass of NH3 =..?
Mass = mole x molar Mass
Mass of NH3 = 5.02 x 17
Mass of NH3 = 85.34g
Therefore, 85.34g of NH3 is produced.
Answer:
The answer is below
Explanation:
1. With the aid of natural hues, the fox can change its color based on the environment it found itself in. For example, during summer and spring, fox color changes to dark to provide itself cover in the environment that is characterized by the brown dirt. Similarly, the fox color changes to white during winter and fall to blend with the snow.
2. In a bid to domesticate fox, it has been observed over many generations that the domesticated fox compared to wild fox has floppy ears and curly tails. The stress hormone level has reduced significantly and they possess a smaller adrenal gland.
The molarity of this should be around 0.846
-----
Formula: M= mols/liters
-----
So… M= 11.6/13.7⇒ 0.846
-----
The base conjugate acid pair when strong acid is added to methylamine CH3NH2 is
base CH3NH2; conjugate acid: CH3NH3 +
Explanation
When a base CH3CH2 accept proton it form its conjugate acid which known as methyl ammonium ion. Therefore conjugate acid of CH3CH2 is CH3NH3+ ion
For example when CH3CH2 react with HCl
CH3CH2 +HCl → CH3CH3+ + Cl-
