Answers

Answer 1

Answer: the type of mixture that scatters light and cannot be filtered is : A colloid

Colloids include gels, sols, and emulsions and it consist of non-crystalline substance that has large molecules

hope this helps

Answer 2

Answer: Colloids. The particles are usually clumpy.

Answers

A soluble ionic compound in aqueous form will be able to 4. conduct current

An aqueous ionic compound is able to conduct current because:

They possess charged ions
They are able to move around

As a result of being able to move around in a solution, the ions of aqueous compound will be able to carry electricity from one point to another and so will be able to conduct electricity.

In conclusion, aqueous solutions of ionic compounds can conduct current.

Find the number of moles of argon in 452 g of argon

Answers

no. of moles = given mass/atomic mass

= 452/40

= 11.3.

Thus, there are 11.3 moles

nó of moles =given mass/molar mass
no of moles=452/39.9
therefore no of moles=11.3moles

3 Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change?
A It doubles.
B It stays the same.
C It increases greatly.
D It decreases slightly.

Answers

1) Answer is: B They both dissociate completely, with little or no reverse reactions.

Some of strong acids: HNO₃(nitric acid), HCl(hydrochloric acid), H₂SO₄(sulfuric acid), HI(hydroiodic acid). Strong bases are: sodium hydroxide (NaOH), barium hydroxide (Ba(OH)₂).

For example, hydrochloric acid, completely dissociate in water and give large amount of hydrogen ions (H⁺): HCl(aq) → H⁺(aq) + Cl⁻(aq).

Sodium hydroxide completely dissociate in water:

NaOH(aq) → Na⁺(aq) + OH⁻(aq).

2) Answer is: C Matter changes to a plasma state.

Plasma is a an ionised gas with highly electrical conductivity.

In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container.

Liquids have definite volume, but no fixed shape.

Gases (for example nitrogen and neon) not have definite volume and fixed shape, it depends on its container.

3) Answer is: B It stays the same.

p₁ = P; initial pressure.

p₂ = 15.5 P; final pressure.

V₁ = V: initial volume.

V₂ = ?: final volume.

T₁ = T; initial temperature.

T₂ = 15.5T; final temperature.

The combinated gas law: The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure: p₁·V₁/T₁ = p₂·V₂/T₂.

P·V/T = (15.5P · V₂) / 15.5 T.

V₂ = V₁ = V.
