The answer must show the lowest number of significant number of significant places in the decimal region

Explanation:

5.67 + 0.00032 adds up to 5.67 because the least number of significant figures in the decimal place 2.

  • To add up two numbers, that are in decimal places.
  • Identify the number of significant figures in them
  • Their addition should sum up to a value no more than the significant figures to the right of the decimal having the lowest accuracy.

           5.67

        + 0.00032

to the right of the decimal, they have two significant numbers.

The answer should also be this way.

A blue whale has a length of 28,578 millimeters. What is the length of a blue whale in kilometers? Show your work below by writi
kotegsom [21]

Answer:

Length of whale in km = 0.028578 km

Explanation:

Given:

Length of whale = 28,578 millimeter

Find:

Length of whale in km

Computation:

We know that;

1 km = 1,000,000 mm

So,

Length of whale in km = 28,578 / 1,000,000

Length of whale in km = 0.028578 km

Balance each reaction and write its reaction quotient, Qc:(b) SF₆(g) + SO₃(g) → SO₂F₂(g)
IceJOKER [234]

When we balance the given equation

      SF₆(g) + SO₃(g) → SO₂F₂(g)

We will get

      SF₆(g) + 2SO₃(g) → 3SO₂F₂(g)

Solution:

Balancing the given equaation

      SF₆(g) + SO₃(g) → SO₂F₂(g)

We have to balance the given number of O

      SF₆(g) + 2SO₃(g) → 3SO₂F₂(g)

We get balanced equation

      SF₆(g) + 2SO₃(g) → 3SO₂F₂(g)

The reaction quotient will be

     Qc = [product] / [reactant]

     Qc ​= [SO₂F₂(g)] / [SF₆(g) + SO₃(g)]

Why can’t there be a temperature lower than absolute zero
Firdavs [7]
Atoms cannot physically get more compact (temperature lowering increases the space between atoms) At absolute zero, the atoms are as physically close together as allowed by the physical laws governing it.

Which best explains what happens to the carbon atoms in carbon dioxide during photosynthesis?A They are incorporated into molecu
Mademuasel [1]

Answer:

A They are incorporated into molecules of sugar.

Explanation:

Photosynthesis is the metabolic process whereby sugar molecules are synthesized by plants in the presence of sunlight (light energy). For this process to occur, carbon dioxide (CO2) and water (H2O) are needed as reactants from external sources. Hence, the photosynthetic equation is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

According to this question, the carbon atoms in carbon dioxide are incorporated into sugar molecule (glucose). It takes 6 carbon atoms to produce one glucose molecule (C6H12O6). This process involves series of reaction in the light-independent stage of photosynthesis to occur.

The concentration of dye in Solution A is 26.609 M. You have 13 mL of water at your disposal to make the dilutions. The solution
exis [7]

Answer:

6,613 M

Explanation:

Dilution is the process of reducing the concentration of a solute in solution, mixing initial solution with more solvent.

The concentration of Solution B is:

23,881 M ×  = 9,552 M

Because the initial eight parts are diluted to 12+8 parts.

Thus, concentration of solution C is:

9,552 M ×  = 6,613 M

I hope it helps!
