Chemistry

Answer:

Yes!

Explanation:

The Earth takes 365.24 days to orbit the sun, as we move around the Sun during the year, the amount of light each area of the planet receives varies in length. When the Earth’s axis points towards the Sun it is summer and when the Earth’s axis points away from the sun it is summer. So while the sun is rotating in between the times of the 6mths to get from one season to the other we have spring and autumn. The earth’s movement around the sun causes the seasons, but it does not affect the temperatures during the seasons. Fun fact many people believe that the temperature changes based on the sun, however during the summer months the earth is further away from the sun in July and closest to the sun in January in the winter months.

Answer:

Yes

Explanation:

The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The North pole always points the same way as the Earth revolves around the Sun.

A mixture of 18 % 18% disinfectant solution is to be made from 16 % 16% and 23 % 23% disinfectant solutions. How much of each so
jeka94

Answer: 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.

Explanation:

According to the dilution law,

C_1V_1+C_2V_2=C_3V_3

where,

C_1 = concentration of ist disinfectant solution = 16 %

V_1 = volume of pure acid solution = x gallons

C_2 = concentration of another disinfectant solution= 23%

V_2 = volume of another acid solution= (28-x) gallons

C_3 = concentration of resulting disinfectant solution = 18 %

V_1 = volume of resulting acid solution = 28 gallons

16\times x+23\times (28-x)=18\times 28

x=20galllons

(28-x) = (28-20) = 8 gallons

Thus 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.

What is the molarity of 200 mL of solution in which 2.0<br> molesof sodium bromide is dissolved?
vodomira [7]

Answer:

10 M

Explanation:

Molarity -

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

n = moles of solute ,

From the question,

V = 200mL

Since, 1L = 1000mL ,

1 mL = 0.001 L

Hence,

V = 200mL = 0.2 L

n = 2.0 mol

Hence, to calculate the molarity of the solution, the above formula can be used as -

M = n / V

M = 2.0 mol / 0.2 L = 10 M

The volume of a sample of water is 2.5 milliliters (mL). The volume of this sample in liters (L) is
Masteriza [31]

Answer:

2.5 Times . 10–3 L.

Explanation:

1 L = 1000 mL

1 mL = 1×10⁻³ L

2.5 mL / 1000 = 2.5×10⁻³ L

2.5 mL . 1×10⁻³ = 2.5×10⁻³ L
