Answer:

Carbon has a total of four bonded pairs of electrons around it.

Explanation:

Since there are four "lines" around the C (which stands for Carbon), we can conclude that Carbon has a total of four bonded pairs of electrons around it.

What are the potential problems for nearby water sources when using nuclear energy? Check all that apply.
Usimov [2.4K]

The energy discharged at the time of nuclear fusion or fission, mainly when used to produce electricity is known as nuclear energy. Although nuclear energy has become one of the most potent sources of energy in the present time, it also brings some harmful effects along with it, mainly by affecting the surrounding environment like the water bodies present nearby.  

Some of the potential problems for the nearby water sources when using nuclear energy are:  

1. It contaminates water with radioactive waste.  

2. It creates hazardous conditions for the species living in the water.  

3. It adds very hot water to cool water environments.  

4. It utilizes a resource, which becomes scarce at the time of drought.

If 4.35 grams of zinc metal react with 35.8 grams of silver nitrate, how many grams of silver metal can be formed and how many g
vaieri [72.5K]
The balanced chemical reaction is written as:

<span>Zn + 2AgNO3 = Zn(NO3)2 + 2Ag

To determine the grams of silver metal that is being produced, it is important to first determine which is the limiting reactant and the excess reactant from the given initial amounts. We do as follows:

4.35 g Zn ( 1 mol / 65.38 g ) ( 2 mol AgNO3 / 1 mol Zn ) = 0.1331 mol AgNO3 needed
35.8 g AgNO3 ( 1 mol / 169.87 g ) ( 1 mol Zn / 2 mol AgNO3 ) = 0.1054 mol Zn needed

Therefore, the limiting reactant would be the zinc metal since it would be consumed completely in the reaction. The excess amount of AgNO3 would be:

0.2107 mol AgNO3 - 0.1331 mol AgNO3 = 0.0776 mol AgNO3 left ( 169.87 g / 1 mol ) = 13.19 g AgNO3 left

0.0665 mol Zn ( 2 mol Ag / 1 mol Zn) ( 107.9 g / 1 mol) = 14.3581 g Ag produced</span>
