How many grams are in a sample of 0.55 mol of K?

Chemistry
1 answer:
Katyanochek1 [597]3 years ago
4 0
The equation you use here is
mass =moles x Mr

So:
Moles of K - 0.55mol
Mr of K - 39.1

Mass= 0.55x39.1 =21.505g

Draw the best Lewis structure for CH 3 -1. What is the formal charge on the C?
djyliett [7]

Answer :  The formal charge on the C is, (-1) charge.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, CH_3^{-1}

As we know that carbon has '4' valence electrons and hydrogen has '1' valence electron.

Therefore, the total number of valence electrons in CH_3^{-1} = 4 + 3(1) + 1 = 8

According to Lewis-dot structure, there are 6 number of bonding electrons and 2 number of non-bonding electrons.

Now we have to determine the formal charge on carbon atom.

Formula for formal charge :

\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}

\text{Formal charge on C}=4-2-\frac{6}{2}=-1

The formal charge on the C is, (-1) charge.

Susan uses Doppler radar to analyze wind patterns in five cities and determine how windy it is. Which statement describes how sh
andrezito [222]

Answer

Susan can process wind speed data from different regions.

Explanation

A Doppler radar is used in weather forecasting in measuring the direction and speed of objects such as drops of precipitation. It determines if the movement occurring in the atmosphere is horizontally towards or way from the radar. Susan can obtain velocity data about objects at a distance which might be water droplets thus be able to predict a coming weather
