Answers

Answer 1

The molarity of the solution that contains 87.75 g of NaCl in 500 mL of the solution is 3 M

What is molarity?

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

How to determine the mole of NaCl Mass of NaCl = 87.75 g ofMolar mass of NaCl = 23 + 35.5 = 58.5 g/mol Mole of NaCl =?

Mole = mass / molar mass

Mole of NaCl = 87.75 / 58.5

Mole of NaCl = 1.5 mole

How to determine the molarity Mole of NaCl = 1.5 mole Volume = 500 mL = 500 / 1000 = 0.5 L Molarity =?

Molarity = mole / Volume

Molarity = 1.5 / 0.5

Molarity = 3 M

The statement about the design that is correct is that; This a block design with fields as blocks and seed types as treatments.

What is random block design?

From the complete question seen online, we see that the researchers in this agricultural testing divide each field into six sections and then randomly assign one variety of corn seed to each section in that field.

Now, we are further told that this procedure above is repeated for each field and at the end of the growing season, the corn will be harvested, and the yield measured in tons per acre will be compared.

Finally, we can say that this is a block design because it is an experiment where the fields that have certain characteristics are grouped together to form blocks, while the treatments are the variety of corn seeds that are randomly assigned within each block.

Describe the energy conversions that occur as a microwave oven heats a cup of water

Answers

The conversions are:

Electrical to electromagnetic and mechanical (when we turn on the microwave).

Electromagnetic to thermal (as the microwave heats up the cup of water).

What energy conversions occur?

We will describe the process in which you already have a cup of water inside the microwave.

First, you turn on the microwave. Here you are giving the microwave electrical energy so it can work.

The microwave rotates the cup of water, so there is a transformation of electric energy into mechanical energy.

The microwave also creates electromagnetic radiation which affects the cup, so there is a change from electric energy to electromagnetic energy.

This electromagnetic energy interacts with the water by increasing the temperature, so finally we have a change from electromagnetic energy to thermal energy.
