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

If you flow a solution of Mg CO3-- in water over a Cation resin, what will be in the outlet stream leaving the bed
vodka [1.7K]

In a a cation-exchange resin, the outlet stream leaving the bed will contain H^{+} and CO_3 ^{2-}.

<h3>What is cation-exchange resin?</h3>
  • A resin or polymer that serves as a medium for ion exchange is known as an ion-exchange resin or cation-exchange resin.
  • It is an insoluble matrix (or support structure) made from an organic polymer substrate, typically appearing as tiny (0.25-1.43 mm radius) microbeads that are white or yellowish in color.
  • The process is known as cation-exchange resin because the beads are often porous, providing a wide surface area on and inside them where the trapping of ions takes place along with the concomitant release of other ions.
  • cation-exchange resin comes in many different varieties. Polystyrene sulfonate is the main ingredient in most commercial resins. Many diverse separation, purification, and decontamination techniques use cation-exchange resin.
  • The most typical examples are water filtration and water softening.

How can helium exist in three different forms
saul85 [17]

Explanation:

Helium exists in three different forms due to the phenomenon of isotopy. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nuclei.

  • The atoms of these elements are called isotopes.
  • This is why Helium can exist in three different forms.
  • Isotopes have the same electronic configuration but with the same chemical properties.

An antacid tablet weighing 0.853g contained calcium carbonate as the active ingredient, in addition to an inert binder. When an
ArbitrLikvidat [17]

Answer:

0.22 g of CO2 were produced.

Explanation:

First, let's represent what is happening with an hypothetical chemical equation just to have a clearer vision of the presented process:

CaCO3 (aq) + 2 HAc (aq) → CaAc2 (aq) + H2O (l] + CO2 (g)

We have a tablet that has CaCO3 as the active ingredient that when combined with an acid, in this case represented as HAc, reacts producing a Calcium salt, water and carbon dioxide that will leave the solution as gas.

Having said that, we know that the initial mass of the reactants will have to maintain during the chemical reaction, or what is the same, the quantity of matter during the process will not change. So, if we have a tablet that weighs 0.853 g and we add an acid solution of 56.519 g, then we have that the initial mass of the reactants will be:

0.853 g from tablet + 56.519 g from acid solution = 57.372 g

This amount of matter should be the same after the reaction, but we know that the CO2 gas will leave the solution once it's formed, so considering that the resulting solution weighs 57.152 g we could calculate the mass of CO2 produced:

57.372 g of initial mass - 57.152 g of resulting solution = 0.22 g of CO2 that left the aqueous solution as gas.
