In the covalent compound CH3, the Greek prefix used to represent the anion is Answer here​
Contact [7]

Answer:

Tri.

Explanation:

''Tri'' is the Greek prefix used to represent the CH3 because there are three hydrogen atoms to form the covalent compound so in Greek method ''Tri'' is used for three. In Greek system, there are certain names for prefixes such as ''di'' is used for two, ''tri'' is used for three, ''tetra'' is used for four etc. This method only provides information about the number of atoms that form the covalent compound.

Why was the clean air act of 1990 so important and how specifically did it change what factors were doing?
Charra [1.4K]
The clean air act of 1990 was important because it helped reduce pollution and keep the enviornment safe. The act organized the idea's of 'safe' in regards to the ozone layer and also the air (generally). This meant that the amount of acid rainfall was controlled. It set rules and policies regarding polluting. Basically, people needed to wake up and think about the enviornment. Companies, people, and even communities were all now responsible for keeping what they breathe (air) clean.

Does this explain it pretty well? If not, please feel free to comment! Thanks for being part of Brainly. :)

A solution was prepared by dissolving 195.0 g of KCl in 215 g of water. Calculate the mole fraction of KCl. (The formula weight
defon

Answer:

Approximately 0.180.

Explanation:

The mole fraction of a compound in a solution is:

\displaystyle \frac{\text{Number of moles of compound in question}}{\text{Number of moles of all particles in the solution}}.

In this question, the mole fraction of \rm KCl in this solution would be:

\displaystyle X_\mathrm{KCl} = \frac{n(\mathrm{KCl})}{n(\text{All particles in this soluton})}.

This solution consist of only \rm KCl and water (i.e., \rm H_2O.) Hence:

\begin{aligned} X_\mathrm{KCl} &= \frac{n(\mathrm{KCl})}{n(\text{All particles in this soluton})}\\ &= \frac{n(\mathrm{KCl})}{n(\mathrm{KCl}) + n(\mathrm{H_2O})}\end{aligned}.

From the question:

  • Mass of \rm KCl: m(\mathrm{KCl}) = 195.0\; \rm g.
  • Molar mass of \rm KCl: M(\mathrm{KCl}) = 74.6\; \rm g \cdot mol^{-1}.
  • Mass of \rm H_2O: m(\mathrm{H_2O}) = 215\; \rm g.
  • Molar mass of \rm H_2O: M(\mathrm{H_2O}) = 18.0\; \rm g\cdot mol^{-1}.

Apply the formula \displaystyle n = \frac{m}{M} to find the number of moles of \rm KCl and \rm H_2O in this solution.

\begin{aligned}n(\mathrm{KCl}) &= \frac{m(\mathrm{KCl})}{M(\mathrm{KCl})} \\ &= \frac{195.0\; \rm g}{74.6\; \rm g \cdot mol^{-1}} \approx 2.61\; \em \rm mol\end{aligned}.

\begin{aligned}n(\mathrm{H_2O}) &= \frac{m(\mathrm{H_2O})}{M(\mathrm{H_2O})} \\ &= \frac{215\; \rm g}{18.0\; \rm g \cdot mol^{-1}} \approx 11.9\; \em \rm mol\end{aligned}.

The molar fraction of \rm KCl in this solution would be:

\begin{aligned} X_\mathrm{KCl} &= \frac{n(\mathrm{KCl})}{n(\text{All particles in this soluton})}\\ &= \frac{n(\mathrm{KCl})}{n(\mathrm{KCl}) + n(\mathrm{H_2O})} \\ &\approx \frac{2.61 \; \rm mol}{2.61\; \rm mol + 11.9\; \rm mol} \approx 0.180\end{aligned}.

(Rounded to three significant figures.)
