It takes about 38 m3 of boards and plywood to build an average-size, single-family home. Can an average-size, single-family home

be built with one day’s output from the saw mill? About how many days will it take for the saw mill to produce enough lumber to build a neighborhood of 100 average-size homes?

A) The answer to whether an average-size, single-family home be built with one day’s output from the saw mill is; No, it can't be built from one days output

B) The number of days will it take for the saw mill to produce enough lumber to build a neighborhood of 100 average-size homes is; 1100 days

A) From research, the average size capacity saw mill usually produces around 1500 board feet of boards per day.

Now, converting board ft to cubic meter gives;

1 board feet = 1/424 m³

Thus; 1500 board feet = 1500 * 1/424 ≈ 3.54 m³

Now, we are told that it takes 38 m³ of boards and plywood to build an average size single family home.

Since one days output = 3.54 m³

It is less than the volume required for the average sized house and so the daily output will not be sufficient.

B) Number of days to produce enough boards and plywood for the average sized family home = 38/3.54 ≈ 11 days

Thus, for 100  homes;

Number of days = 100 * 11 = 1100 days

Answer: option D) hypothesis

Explanation:

Kim proposal is an hypothesis, because it is an assumption that will ONLY be accepted as true (i.e becomes a theory) when butadiene successfully makes the glue stickier in several conducted experiments.

But, at the moment Kim proposal is an hypothesis.

What is the minimum pressure in kPa that must be applied at 25 °C to obtain pure water by reverse osmosis from water that is 0.2
Nadya [2.5K]

This is an application of osmotic pressure which is one of the colligative properties of substances. The formula of osmotic pressure is expressed as P = MRT where M is molarity , R is the gas constant and T is temperature. When M is equal to a total of 0.305 M and T is equal to 298 K ,  P should be equal to 7.46 atm

How many moles of potassium sulfate are present in a sample that weighs 45.8g?
Nikitich [7]

Answer:

0.263 mol

Explanation:

K2SO4 - potassium sulfate

Molar mass (K2SO4) = 2*39.0983 + 32.065 + 4*15.9994 =

= 174.2592≈174.26 g/mol

45.8 g * 1 mol/174.26 g = 0.263 mol

A sample of ethanol (C2H6O) has a mass of 0.2301 g. Complete combustion of this sample causes the temperature of a bomb calorime
Keith_Richards [23]

Answer:  4.994\times 10^{-3}  moles

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

Given mass of ethanol = 0.2301

Molar mass of ethanol = 46.07 g/mol

\text{Number of moles of ethanol}=\frac{0.2301g}{46.07g/mol}=4.994\times 10^{-3}

Thus there are 4.994\times 10^{-3}  moles of ethanol are present in the sample.

Calculate the pH of a buffer solution prepared by mixing 75.0 mL of 1.00 M lactic acid and 25.0 mL of 0.50 M sodium lactate.
max2010maxim [7]

From the calculations, the pH of the buffer is 3.1.

<h3>What is the pH of the buffer solution?</h3>

The  Henderson-Hasselbach equation comes in handy when we deal with the pH of a buffer solution. From that equation;

pH = pKa + log[(salt/acid]

Amount of the salt = 25/1000 *  0.50 M = 0.0125 moles

Amount of the acid = 75/1000 *  1.00 M = 0.075 moles

Total volume = ( 25 + 75)/1000 = 0.1 L

Molarity of salt = 0.0125 moles/0.1 L = 0.125 M

Molarity of the acid = 0.075 moles/0.1 L = 0.75 M

Given that the pKa of lactic acid is 3.86

pH = 3.86 + log( 0.125/0.75)

pH = 3.1
