<h3>Answer:</h3>

Final volume is 120 L

<h3>Explanation:</h3>
  • Using the dilution concept, dilution involves adding more solvent to a concentrated solution to make it dilute. This results to a dilute solution with less solute concentration and more solvent.

According to the dilution equation;

M1V1 = M2V2

Where, M1 is the molarity  and V1 is the volume of the concentrated solution, while M2 and V2 are the molarity and volume of the diluted solution respectively.

In this case;

M1 = 12.0 M

V1 = 30 L

M2 = 3.0 M

V2 = ?

Therefore;

V2 = M1V1 ÷ M2

    = (12 × 30) ÷ 3

   = 120 L

Hence, the final volume will be 120 liters

A photon has an energy of 1.10 x 10 -13 j. What is the photon's wavelength? What type of electromagnetic radiation is it?
lawyer [7]

Answer:

λ  = 0.002 nm

The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.

Explanation:

Given data:

Energy of photon = 1.10 × 10⁻¹³ J.

Wavelength of photon = ?

Solution:

Formula:

E = h.c / λ

λ  = h. c / E

λ  = 6.626 × 10⁻³⁴ j. s × 3×10⁸ m/s / 1.10 × 10⁻¹³ J.

λ  = 19.878 × 10⁻²⁶m /  1.10 × 10⁻¹³ J

λ  = 18.071 × 10⁻¹³ m

λ  = 18.071 × 10⁻¹³  × 10⁹

λ  = 18.071 × 10⁻⁴ nm

λ  = 0.002 nm

The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.

The class measured the density of a copper block to be 8.6 +/-0.2 g/cm3 at the 95% confidence interval with a standard deviation
mezya [45]

Answer: kindly check explanation

Explanation:

Given the following :

Measured density of copper block:

8.6+/-0.2 g/cm3

True density = 8.96g/cm3

Standard deviation = 0.4g/cm

a. What is the high and low number of the confidence interval range?

High : 8.6 + 0.2 g/cm3 = 8.8g/cm³

Low : 8.6 - 0.2 g/cm3 = 8.4g/cm³

Does the true value fall within the confidence interval? NO

Actual density = 8.96g/cm³ doses not lie in between (8.4 - 8.8)g/cm³

B.) High and low of the standard deviation range?

High = 8.6 + 0.4 = 9.0g/cm³

Low = 8.6 - 0.4 = 8.2g/cm³

Value falls within range of the true density value of copper block.

8.96g/cm³ falls in-between (8.2-9.0)g/cm³

What happens when you increase the temperature of a reaction?
aalyn [17]
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
