Hypothesis: Which materials do you think will meet the special needs of Parvus' house? Use the drop-down selections to create yo

ur hypotheses. Be sure to record your hypotheses on your lab report. If we use Select to build the roof of the house, then the temperature inside the house will remain cooler. If we use Select to build the walls and floors of the house, then the temperature inside the house will remain cooler. If we use Select to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. If we use Select to construct the latches on the windows and doors, then the magnetism will keep the latches secure.

Answer:

This question is incomplete as it lacks the options for each hypothetical statement. The options for each hypothesis are:

wood, clay brick, iron, aluminum, copper, or nickel

The answers to each hypothesis are:

1. Wood

2. Clay brick

3. Copper

4. Iron

Explanation:

Firstly, a hypothesis is a testable explanation given to explain an observed problem or to answer a question. In this case, "which materials will meet the special needs of Parvus' house?" is the question.

The question requires one to complete the given hypotheses using the options given.

- If we use WOOD to build the roof of the house, then the temperature inside the house will remain cooler. The best answer is "wood" because wood conducts/absorbs heat the least among the materials that can be used for roofing, hence, it will make the inside of the house cooler.

- If we use CLAY BRICK to build the walls and floors of the house, then the temperature inside the house will remain cooler. Clay brick is the best material for building walls and floors of a house among the option. Also, it conducts heat fairly making the interior of the house cool.

- If we use COPPER to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. Copper, among all other metal, is the best conductor of electricity due to its properties including low resistivity. Hence, using copper will make electricity to flow into the home at a faster rate.

- If we use IRON to construct the latches on the windows and doors, then the magnetism will keep the latches secure. Iron is the metal with the best magnetic property. Therefore, using it to construct the latches on the windows and doors will guarantee magnetic security.

What mass of salt would you need to add to 1.00kg of water to achieve a freezing point of -5 degrees C
Serga [27]

Answer:

The type of salt to be added to the water is not known from the question but no worries, I will try to give you the step by step procedure to answer any type of question similar to this.

To answer this question, we should know some facts.

1. the molar freezing point depression constant of water (Kf) = 1.86 K kg/mol

2. the molar mass of the salt if NaCl = 58.5 g/mol ; KCl = 74.5 g/mol

3. since the salt can dissociate if NaCl or KCl into two ions, the Van't Hoff factor ( i )= 2

Note that: the change in freezing point, molarity, deepression constant and van't Hoff factor are related by this formula;

                ΔTf = i Kf m

So lets take NaCl as the salt:

Molar mass = 58.5 g/mol

Van't Hoff factor = 2

1. calculate the number of moles

So we can calculate the molarity of the salt NaCl from the formula;

m = ΔTf / i Kf

m = 5 / 2 * 1.86

m = 5 / 3.72

m = 1.344 mol/kg

2. calculate the number of moles of the salt required

Next is to multiply the molarity by the mass of water. Density of water = 1kg/L

number of moles = 1.344 mol/kg * 1 Kg/L * 1 kg water

number of moles = 1.344 moles.

3. calculate the mass of the salt.

numner of moles = mass / molar mass

mass = number of moles * molar mass

mass = 1.344 * 58.5

mass = 78.624 g of NaCl salt.

You can follow these steps to solve for the type of salt you are given in the question.

How long does it take for only one eighth of a sample of radon-222 to remain
Alex17521 [72]
1/8=(1/2)^3 and the half life of radon is 3.8days

Half life is the time it takes for half of any amount of a radioactive substance to decay into something else.

Therefore for a sample of radon to decay to 1/8 of its original amount, it would take 3 x 3.8days=11.4 days

How can you make a 250 ml 0.5 m solution of NaCl<br>show steps
GarryVolchara [31]

Answer:

Add water to 29.22 grams of salt until you get 1 liter of volume, stir it until the salt completely dissolves and mixes and voila! you will have a 0.5 M NaCl solution.
