Which of the following best represents potential energy being converted to kinetic energy? (2 points) The chemical energy in a b
Ilia_Sergeevich [38]

Answer: A woman kicks a soccer ball and scores a goal.

Explanation:

Potential energy: it is the energy possessed by the body due to its position.

Kinetic energy: it is the energy possessed by the the body  due to its motion.

When a woman kick's a soccer ball she transferred her potential energy to soccer ball.Due to this action soccer ball comes into motion which means potential energy imparted to the ball starts getting converted into kinetic energy.

If 45.0 mL of a 0.0500 M HNO3, 10.0 mL of a 0.0500 M KSCN, and 30.0 mL of a 0.0500 M Fe(NO3)3 are combined, what is the initial
jeka94

Answer:

the  initial concentration of SCN- in the mixture is 0.00588 M

Explanation:

The computation of the initial concentration of the SCN^- in the mixture is as follows:

As we know that

KSCN \rightarrow K^ + SCN^-

As it is mentioned in the question that KSCN is present 10 mL of 0.05 M

So, the total milimoles of SCN^- is

= 10 × 0.05

= 0.5  m moles

The total volume in mixture is

= 45 + 10 + 30

= 85 mL

Now the initial concentration of the SCN^- is

= 0.5 ÷ 85

= 0.00588 M

hence, the  initial concentration of SCN- in the mixture is 0.00588 M

Nucleotide bases bonded to a sugar phosphate backbone make up _____.
Alchen [17]
Nucleotide bases bonded to a sugar phosphate backbone make up nucleic acids such as DNA (deoxyribonucleic acid) and RNA (<span>ribonucleic acid)</span>. Nucleotides have three major parts: sugars, phosphates, and a nitrogenous base. DNA uses four nitrogenous bases: Adenine, Guanine, Cytosine, and Thymine. RNA uses the same bases except for Thymine, which is replaced by Uracil.
