How many moles of kf are contained in 244 ml of 0.135 m kf solution? the density of the solution is 1.22 g/ml?
galben [10]
The Molarity of a solution = number of moles / volume.  
Volume = 244ml = 0.244L
 So it follows that number of moles = Molarity * volume 
 Number of moles = 0.135 * 0.244 = 0.03945.
 Hence the number of moles = 0.03945

match the number of negative charges to the number of positive charges to make each combination balanced (see image for answer)
BartSMP [9]

Answer : The correct match is:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges

Explanation :

As we now that there are three subatomic particles which are protons, electrons and neutrons.

The protons and neutrons are located inside the nucleus and electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and neutrons are neutral.

As we know that all the things are made up of charges and opposite charges attract to each other.

In a neutral atom, the positive charges and negative charges are balanced in an object. That means, in neutral atom the number of positive charges are equal to the negative charges.

So we can say that:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges

What is the percent yield of alum if 0.4000 grams of aluminum is used in the synthesis of alum and 4.8946 grams of alum is actua
slamgirl [31]
% yield = actual yield/ theoretical yield x 100%

4.8946 / 0.4 = 12.2365 

% yield = 12.2365 x 100 = 1223.65%
