Fun question; Naurto or sauske​

Answer:

A: Add a substance to the wash that reduces the number of charges transferred.

Explanation:

The attraction between opposite charges make the clothes attract together. To reduce them Increase the temperature of the air in the dryer to weaken the electric forces. Hence, option A is correct.

An electric dryer is used to dry the clothes and hair or other substances using electric current. A substance can have both negative and positive charges. The opposite charges will attract together while the negative charges repel.

By exposing clothes to electric dryer it will gain electrons from the dryer and the positive poles of the clothes will attracts it. The electric current from the dryer will make clothes temporarily polarised.

If temperature increases, the intermolecular force of attraction decreases by making the kinetic energy of molecules raised. Therefore by increasing the temperature of air from the dryer the attraction can be reduced.

The products in the reaction HCI + NaOH → NaCl + H20, are C. NaCl and H20.

The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is a neutralization reaction, which means that it produces a salt and water. In this case, the salt is sodium chloride (NaCl) and the water is H2O.

The other options are not correct because they do not include all of the products of the reaction. Option (A) includes HCl and NaOH, but it does not include H2O. Option (B) only includes HCl and NaOH. Option (D) only includes NaOH and H2O.

In conclusion, option C is correct.

Answer:

  1.7700×10^-22 g

Explanation:

A face-centered-cubic cell contains 4 atoms, so the volume per atom is ...

  (389.80×10^-12 m)³/(4 atoms) ≈ 1.4725×10^-29 m³

Then the mass of 1 atom is ...

  (12020 kg/m³)(1.4725×10^-29 m³) ≈ 1.76995×10^-25 kg

Complete question is;

When solid materials are heated.the heat absorbed/added to the materials caused the materials to change its form from?

Answer:

From solid to liquid

Explanation:

When we heat solid materials, the heat causes the forces of attraction between the molecules to become weaker and as such, the material becomes more loose than it was in the solid state. As a result, the material now becomes a liquid because the molecules now have lesser forces of attraction and are a bit loose.

NaHCO3 + HC2H3O2

Answer: NaC2H3O2 + CO2 + H2O

Answer: a) Temperature of [tex]170^0C[/tex]

b) [tex]C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O[/tex]

c) dehydrating agent

Explanation:

Ethanol is heated with an excess of concentrated sulfuric acid at a temperature of 170°C to produce ethene.

The balanced chemical reaction is:

[tex]C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O[/tex]

Here concentrated sulfuric acid removes a water molecule from ethanol and thus acts as a dehydrating agent.

Explanation:

Answer:

28 g CO

Explanation:

First convert grams to moles.

1 mole C = 12.011 g (I'm just going to round to 12 for the sake of this problem)

12 g C • [tex]\frac{1 mol C}{12 g C}[/tex] = 1 mol C

1 mol O = 15.996 g (I'm just going to round to 16)

16 g O • [tex]\frac{1 mol O}{16 g O}[/tex] = 1 mol O

So the unbalanced equation is:

[tex]C + O_{2}[/tex] -> [tex]CO[/tex] (the oxygen has a 2 subscript because it is part of HONClBrIF meaning when not in a compound these elements appear in pairs - called diatomic elements)

The balanced equation is:

[tex]2 C + O_2[/tex] -> [tex]2 CO[/tex]

However, carbon is the limiting reactant in this equation and two moles cannot react because only 12 g (1 mole) are present. Therefore, use the equation

[tex]C + \frac{1}{2} O_2[/tex] -> [tex]CO[/tex].

1 mole of CO is formed, therefore 12 g + 16 g = 28 g CO.

Answer:

1. 35g NaCl.

2. 234g sugar.

3. 0.506L of concentrated nitric acid are needed.

4. 1.67L of 9.0M copper (II) sulfate are needed

Explanation:

Molarity is defined as the ratio between moles of solute and the volume of the solution.

1. 1.00L * (0.60mol / L) = 0.60 moles NaCl are dissolved

To convert moles to mass we must use its molar mass:

0.60mol NaCl * (58.44g/mol) =

35g NaCl

2. 2L * (0.342mol / L) = 0.684 moles Sugar = moles sucrose

0.684 mol * (342.30g / mol) = 234g sugar

3. 4L of a 2.0M are:

4L * (2.0mol/L) = 8moles

8mol * (1L / 15.8mol) = 0.506L of concentrated nitric acid are needed

4. 3.0L  * (5.0 mol / L) = 15.0 moles copper (II) sulfate.

15.0mol * (1L / 9.0mol) = 1.67L of 9.0M copper (II) sulfate are needed

Explanation:

Answer:

for brass

mass m1 =150g

t1=90°c

specific heat of brass s1=0.380 J/gC.

for water

t2=20°c

mass m2=230g

Specific heat of water s2= 4.18 J/gC,

Explanation:

we have

Q1=Q2

m1s1{t-t1)=m2s2(t2-t)

150×0.380(t-90)=230×4.18(20-t)

57t-5130=961.4×20-961.4t

57t +961.4t=19228+5130

1018.4t=24358

t=24358/1018.4=23.91=24°c is final temperature

Answer:

[tex]\frac{15}{7}N[/tex]

Explanation:

We already know that the mass number of an atom is the sum of the number of protons and the number of neutrons.

So, the mass number of this isotope is;

Number of protons = 7

Number of neutrons = 8

Mass number = 7 + 8 = 15

Hence, the isotope is;

[tex]\frac{15}{7}N[/tex]

Answer:

24

Explanation:

In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6.

Similarly, since an atom of chromium contains 24 protons, it also contains the same amount of electrons, which is 24.

Answer:

24 is your answer
