What is molarity of a solution containing 0.34 moles of FeCl3 in the 0.45 liters of water
Minchanka [31]
Hello!

Molarity is defined as the number of moles of a substance that can be found in 1 liter of solution. That is expressed mathematically as M=mol/L

For the FeCl₃ solution:

M= \frac{mol FeCl_3}{L sol}= \frac{0,34 moles FeCl_3}{0,45 L}= 0,756 M

So, the concentration of this solution is 0,756 M

At the top of a hill, an athlete on a skateboard has X joules of mechanical energy. How much mechanical energy will she have at
ExtremeBDS [4]

If an athlete has X joules of mechanical energy at the top of the hill, he will have the same X amount of energy at the bottom of the hill.

<h3>What is mechanical energy?</h3>

Mechanical energy is the addition of kinetic and potential energy. It can be either kinetic or potential energy.

It is the energy possessed by the position or the motion of the body.

It is the energy present to perform any work.

So, the athlete will have X joule of energy at the top and bottom of the hill.

Thus, the correct option is a, X joules.

When a capacitor has a potential difference between the plates it is said to be ? . one plate has an excess of electrons and one
Ede4ka [16]

When a capacitor has a potential difference between the plates it is said to be Constant.

Both plates have different charge which signifies that one has higher potential than the other.

Therefore, when we join them in parallel, charge will flow from higher to lower. and it continued to flow until equilibrium (the entire process took only a few seconds), indicating that the potential remains constant.

To learn more about constant potential difference in capacitor visit:

PLEASE HELP!! (I will mark brainiest) (REAL ANSWERS ONLY PLEASE!)
Inessa [10]

The phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a “backbone” for each single strand of DNA, and the nucleotide bases stick out from this backbone. The carbon atoms of the five-carbon sugar are numbered clockwise from the oxygen as 1′, 2′, 3′, 4′, and 5′ (1′ is read as “one prime”). The phosphate group is attached to the 5′ carbon of one nucleotide and the 3′ carbon of the next nucleotide. In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases.
