Sandstone and slate are used for building, but these rocks have different properties. Which rock would you use for a use for roof? Which would you use the walls of a building? Explain. Please help ty

Answers

Answer 1

Answer: Slate is a natural stone that splits easily into thin sheets. A sheet of slate can be cut into shingles that provide excellent protection against rain and melting snow, and it is very dense and hard, therefore it is highly resistant to being reshaped or damaged by weather. Sandstone can be broken into flat layers that can then be broken into squared-off chances. These pieces of squared-off sandstone serve well in construction of walls for buildings.

1. If you have a 1-g sample of Po-218, how many grams would youhave after 6 minutes? After 18 minutes?

Answers

Answer:

a) 0.25 g b) 0.01542 g

Explanation:

Half life of Po-218 = 3.04 minutes

initial mass = 1 g

after 3.04 minutes it will remain 0.5 g

after another 3.04 minutes it will remain 0.25 g

After 6 minutes it will remain approx 0.25 g

B) after another 3.04 minutes it will remain 0.125 g

after another 3.04 minutes it will remain 0.0625 g

after another 3.04 minutes it will remain 0.03125 g

after another 3.04 minutes it will remain 0.015625 g

After 18 minutes it will remain approx 0.01542 g

How do we separate sugar solution with sand

Answers

A sugar solution with sand can be separated by dissolving the solution into water, then the sugar will be dissolved with the water and the sand will stay on the bottom of the water.

you can separate both sand and sugar by adding water because sugar will dissolve sand cannot

Indicate whether each of the following substances would be more soluble in H2O or C6H14:(a) KI

(b) C8H18

(c) grease

(d) CH3(CH2)12OH

(e) NaC2H3O2

Answers

Answer:

H2O-a,e, C6H14 - b,c,d

Explanation:

H2O - (a) KI, e(NaC2H3O2) because they are ionic compounds

C6H14 -(b) C8H18, (c) grease, (d) CH3(CH2)12OH because they are mostly un-polar.

Final answer:

KI and NaC2H3O2 are ionic and therefore more soluble in polar solvents like H2O, while C8H18, grease, and CH3(CH2)12OH are nonpolar and more soluble in nonpolar solvents like C6H14.

Explanation:

The solubility of a substance generally follows the principle of 'like dissolves like'. That means polar substances are more soluble in polar solvents (like H2O) and nonpolar substances are more soluble in nonpolar solvents (like C6H14).

KI is ionic, therefore it is polar and more soluble in H2O.
C8H18 is nonpolar, hence more soluble in C6H14.
Grease is nonpolar, so it is more soluble in C6H14.
CH3(CH2)12OH is nonpolar due to the long hydrocarbon chain, making it more soluble in C6H14, despite the polar OH group at the end.
NaC2H3O2 is ionic, hence it is polar and more soluble in H2O.
