Ilya [14]3 years ago
8 0

Answer:

100 cal

Explanation:

Given data:

Mass of carbohydrate = 19 g

Mass of protein = 1 g

Mass of fats = 4 g

Solution:

The average calories content of

Protein 4 cal/g

Carbohydrate 4 cal/g

Fat 9 cal/g

Then,

1 g protein × 4 cal/g =  4 cal

4 g fat × 9 cal/g = 36 cal

19 g carb. × 4 cal/g = 76 cal

               Total calories = 116 cal  

Round to one significant figure = 100 cal

Identify and describe the three ways that mutations affect organisms?
Soloha48 [4]

Answer:

The ways that mutation can affect an organism include:

Changing the physical characteristics of the organism.

It can impact the way that the DNA is able to code the genetic information.

Also, mutation can lead to the death of an organism.

What is mutation?

Mutation simply means a change in the DNA sequence of an organism. It can result from DNA copying mistakes that were made during the cell division.

Mutation can affect an organism as it changes the phenotype of the organism. It can also impact the way that the DNA is able to code the genetic information and lead to the death of an organism.

The greatest amount of energy released per gram of reactants occurs during a(1) redox reaction
masya89 [10]

Answer : The correct option is, (2) Fission reaction.

Explanation :

  • Fission reaction : This is a type of nuclear reaction in which the splitting of bigger nuclei into two smaller nuclei takes place. During this process, the large amount of energy is released.
  • Redox reaction : This is an oxidation-reduction reaction in which the electrons transferred between the two molecules.
  • Substitution reaction : In this reaction, one functional group is replaced by the another functional group in a chemical compound.
  • Neutralization reaction : In this reaction, the acid and base react to give water and a salt.

Redox reaction, substitution reaction and neutralization reaction are the chemical reactions in which the heat releases when the chemical bonds are breaking and forming.

Therefore, the greatest amount of energy released per gram of reactants occurs during the fission reaction.

How many atoms are there in each of the following
oee [108]
<h3>Answer:</h3><h3>a) 9.033 × 10²³ particles</h3><h3>b) 4.068 × 10²⁴ particles</h3><h3>c) 1.51 × 10²³ particles</h3>

Explanation:

For us to answer these questions, we have to know two formulas:

  1. Number of particles = moles × Avogadro's Number
  2. Moles = Mass ÷ Molar Mass

Therefore:

a) particles of Na = 1.50 mol × (6.022 × 10²³) particles/mol

                            = 9.033 × 10²³ particles

b) particles of Pb = 6.755 mol × (6.022 × 10²³) particles/mol

                            = 4.068 × 10²⁴ particles

c) particles of Si

             = (7.02 g ÷ 28.085 g/mol) × (6.022 × 10²³) particles/mol

             = 1.51 × 10²³ particles
