What happened to the mixture as it is poured into the strainer with cloth?​

zzz [600]3 years ago

Answer:

The solid particles will be trapped behind on the strainer while the liquid molecules will pass or filter through.

Explanation:

Filtration is a process of separation of mixtures involving an insoluble solid and a fluid such as liquids or gases using a filtering medium such as paper or cloth or any other material. During the process, the liquid molecules pass through the filtering medium whereas the solid particles are not allowed to pass through but are retained by the medium. The reason is that the pores on the filtering medium are only small enough for the liquid molecules to pass through but not the solid particles.

An example of a mixture that can be separated through filtration is a suspension of chalk and water. Also, a mixture of water and solid particles such as water and tea leaves can also be separated using a strainer with cloth.

In the question, if a mixture of insoluble solids in a liquid is passed through a strainer with cloth, the solid particles will be trapped behind on the strainer while the liquid molecules will pass through.

When a sodium (Na) atom forms an ion so that it looks like a noble gas with a full valence shell, what will its charge be?
Setler79 [48]

Answer:

I believe 1+

Explanation:

when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1

When a solution of ammonium chloride, NH4Cl, is added to a solution of lead (II) nitrate , Pb(NO3)2, a white precipitate, PbCl2,
slavikrds [6]

Answer:

B) 2NH_4^+_{(aq)}+2Cl^-_{(aq)}+Pb^{2+}_{(aq)}+2NO_3^-_{(aq)}\rightarrow PbCl_2_{(s)}+2NH^{4+}_{(aq)}+2NO_3^-_{(aq)}

Explanation:

The total ionic equation contains all the species in the reaction in the ionic form.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

Spectator ions are also written in total ionic equations.

The chemical equation is:

2NH_4Cl_{(aq)}+Pb(NO_3)_2_{(aq)}\rightarrow PbCl_2_{(s)}+2NH_4NO_3_{(aq)}

The total ionic equation is -

2NH_4^+_{(aq)}+2Cl^-_{(aq)}+Pb^{2+}_{(aq)}+2NO_3^-_{(aq)}\rightarrow PbCl_2_{(s)}+2NH^{4+}_{(aq)}+2NO_3^-_{(aq)}

What mass of Cu(s) is electroplated by running 30.0 A of current through a Cu2 (aq) solution for 4.00 h
Alborosie

Answer:

The correct answer is "142 g".

Explanation:

According to the question,

⇒ Cu^2+(aq)+2e^  ------> Cu(s)

where,

Z = 2

F = 96500c

C = 30 A

t = 4h

 = 4\times 60\times 60

 = 14400 \ sec

We know that,

Atomic mass of Cu(M) = 63.5 g/mole

Now,

⇒ W=\frac{Mct}{ZF}

On putting the values, we get

        =\frac{63.5\times 30\times 14400}{2\times 96500}

        =\frac{27432000}{193000}

        =142 \ g

A hot air balloon contains 5.30 kL of helium gas when the temperature is 12°C. At what temperature will the balloon's volume hav
frosja888 [35]

Answer:

(A) 50 °C

Explanation:

Ideal gas law:

PV = nRT

If pressure is held constant, then:

V₁ / T₁ = V₂ / T₂

Substituting values:

(5.30 kL) / (12 + 273 K) = (6.00 kL) / T

T = 323 K

T = 50 °C
