Explanation:
Answer:
Valence electron pairs are the total sum of lone pairs and bond pairs in the molecule. The electrons possess negative charge on them. They repel each other due to the presence of same charge. The lone pairs repel other electrons strongly, which are present around the central atom.
Answer:
They mostly dissolve in water, and they are poor conductors of heat.
Answer:
1 x 10^13 stadiums
Explanation:
We are given that;
1 stadium holds = 1 × 10^5 people
Number of iron atoms is 1 × 10^18 atoms
Assuming the stadium would carry an equivalent number of atoms as people.
Then, 1 stadium will carry 1 × 10^5 atoms
Therefore,
To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium. Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18
atoms ÷ 1 × 10^5 atoms/stadium =
1 × 10^13 Stadiums
Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
Answer:
Situation B indicates the significant depression of temperature in the wet bulb thermometer.
Answer Statement: B
Explanation:
Temperature Depression & Relative Humidity
As we can see that there are four cases to study the affect of relative humidity on the temperature measured by thermometers, set up in different situations i.e., one is dry and the other one is dry.
As situation B describes the most admissible temperature drop in the wet bulb thermometer with a relative humidity of approximately 17% i.e., this can be the appropriate to reflect the lowest relative humidity with a fact that the relative humidity reduces with a larger count of temperature depression. Whereas, the relative humidity for other situations are resulting much higher.
