Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
The desirable soil pH for corn ranges from 5.8 to 7.0.
Answer:
D. Incinerating or incineration
Explanation:
Burning trash to reduce the amount of waste on land is called incineration.
Answer: Distillation is a process in which we use the boiling point, condensation of the substances to separate them from each other, it is a physical separation not the chemical because physical property of substance is used in it.
Now, the distinction in between a laboratory distillation and an industrial distillation is that, the distillation process in laboratory distillation works in batches, while in the industrial distillation it occurs in continuous manner, industrial distillation is the large scale distillation.
Answer:
The denominator B = P1V1
Explanation:
We'll begin by writing the combine gas equation. This is shown below:
P1V1/T1 = P2V2/T2
Where:
P1 is the initial pressure.
V1 is the initial volume.
T1 is the initial temperature.
P2 is the final pressure.
V2 is the final volume.
T2 is the final temperature.
Now let us make T2 the subject of the formula to obtain our desired result. This is illustrated below:
P1V1/T1 = P2V2/T2
Cross multiply to express in linear form
P1V1T2 = P2V2T1
Divide both side by P1V1
T2 = P2V2T1/P1V1
From the above illustration,
The numerator A = P2V2T1
The denominator B = P1V1
