Soil is built up of clastic particles, organics, and clay while sand is a combination of rocks, minerals, and fragments of rotting shells.

Soil particles are larger in size and mass together, Sand particles are tinier and individual.

Explanation:

So, the soil is weaker than sand particles. When we mix soil and sand into the water, we acknowledge that soil particles somewhat settle at the bottom while designing parts mixed into water. Sand is almost heavier than water so it settles down at the base.

Soil particles settle faster and will be on the bottom while the sand particles will be on top. And no this is not a great method to define particle size distribution.

Answer:

1. The larger and heavier particles settled first and settled at the bottom.

2. Gravel is settled at the very bottom because it is heavier than sand and clay.

3. No, because each layer has smaller and lighter particles in it.

4. No, because the amount of each type of particle is different in every location.

Giselle is working with a chemical substance in a laboratory. She observes that when the chemical is heated, it gives off a gas.

Phoenix [80]

The correct answer is option B, that is, hypothesis.

A hypothesis refers to an anticipated illustration for an occurrence. It refers to a proposed illustration or a supposition made on the groundwork of inadequate proof as an initiation point for further investigation. In order for a hypothesis to be a scientific hypothesis, the scientific method needs that one can examine it.

Consider the neutralization reaction 2 HNO 3 ( aq ) + Ba ( OH ) 2 ( aq ) ⟶ 2 H 2 O ( l ) + Ba ( NO 3 ) 2 ( aq ) A 0.120 L sample

k0ka [10]

Answer:

The concentration of the HNO3 solution is 0.150 M

Explanation:

Step 1: Data given

Volume of the unknown HNO3 sample = 0.120 L

Volume of the 0.200 M Ba(OH)2 = 45.1 mL

Step 2: The balanced equation

2HNO3 + Ba(OH)2 ⟶ Ba(NO3)2 + 2H2O

Step 3: Calculate moles Ba(OH)2

moles Ba(OH)2 = molarity * volume

moles Ba(OH)2 = 0.200 M * 0.0451 L

moles Ba(OH)2 = 0.00902 moles

Step 4: Calculate moles of HNO3

For 1 mole of Ba(OH)2 we need 2 moles of HNO3

For 0.00902 moles of Ba(OH)2 we need 2*0.00902 = 0.01804 moles

Step 5: Calculate molarity of HNO3

molarity = moles / volume

molarity = 0.01804 / 0.120 L

Molarity = 0.150 M HNO3

The concentration of the HNO3 solution is 0.150 M
