A microwave oven uses electromagnetic radiation to heat water molecules in food or drink. This radiation has a frequency of 2.45 x 10⁹ Hz. Calculate its energy

Answers

Answer:

1.62 × 10⁻²⁴ J

Explanation:

Step 1: Given and required data

Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.s

Step 2: Calculate the energy (E) of this electromagnetic radiation

We will use the Planck-Einstein's relation.

E = h × ν

E = 6.63 × 10⁻³⁴ J.s × 2.45 × 10⁹ s⁻¹ = 1.62 × 10⁻²⁴ J

Answers

Answer:

DNA aka deoxyribonucleic acid is a molecule in cells that holds genetic information. Their main job is to tell the cell what type of protein to make. The other instructions they hold for the organism is instructions on how to develop, survive and reproduce.

Explanation:

DNA is the genetic material made of two polynucleotide chains that coil around one another to create a double helix is called deoxyribonucleic acid (DNA).

All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include ribonucleic acid and DNA.

DNA is the genetic material found inside bodily cells that contribute to an individual's unique genetic makeup. Similar to the game's code or a home's blueprints, it contains the directions for creating the body.

Answer:

[tex]\boxed {\boxed {\sf A. \ 19,320 \ kg/m^3}}[/tex]

Explanation:

We want to find the density. The formula is mass over volume.

[tex]\rho = \frac{m}{v}[/tex]

The mass is 500 kilograms. The volume is 0.026 cubic meters.

[tex]m= 500 \ kg \\v=0.026 \ m^3[/tex]

Substitute the values into the formula.

[tex]\rho= \frac{ 500 \ kg}{ 0.026 \ m^3}[/tex]

Divide.

[tex]\rho = 19230.7692 \ kg/m^3[/tex]

This is just about equal to 19,320 kg/m³, so choice A is correct.

Answer:

A) 19230 kg/ m3

Explanation:

divided it's mass by its volume ti get it's density

500/0.026 = 19230

A 32.14 gram sample of a hydrate of MnSO4 was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, 17.51 grams of the dehydrated compound remained. What is the formula of the hydrate?

Answers

Answer:

MnSO₄.7H₂O

Explanation:

To solve this question, we need to convert the mass of the dehydrated MnSO₄. The difference between mass of the hydrate and dehydrated compound is the mass of water. With the mass we can find the moles of water and the formula of the hydrate:

Moles MnSO₄ -Molar mass: 151g/mol-:

17.51g * (1mol / 151g) = 0.116 moles

Moles H₂O -Molar mass: 18g/mol-:

32.14g-17.51g = 14.63g * (1mol / 18g) = 0.813 moles

The ratio of moles MnSO₄: Moles H₂O represent the amount of water molecules in the hydrate:

0.813mol / 0.116mol = 7 molecules of water.

The hydrate formula is:

MnSO₄.7H₂O
