The mass of a substance is 10 grams. In magnitude, the volume is three more than the density, which is measured in g/cm3. What is the density of this substance?

Answers

Answer:

Explanation:

The expression to use to calculate the density of any substance is the following:

d = m/V (1)

Where:

m: mass (g)

V: Volume (mL or cm³)

Now, we don't have data for the volume of the substance, but the problem states that volume of the substance is three times more than the density, in other words, it means:

V = 3d (2)

With this, we can replace it in (1), and we can calculate the density still:

d = m / 3d (3)

Solving for d, we have the following:

m = 3d²

d² = m/3

d = √m/3 (4)

All we have to do now, is replace the value of the mass here and solve for density:

d = √10/3

d = √3.33

d = 1.82 g/cm³

This is the density of the substance

you have to use the equation d=m/v. Since we are told that volume is three times that of density, we can write v=3d. Dince we are also told that mass is 10g we can make the equation d=10/3d. That means that 3d^2=10 which can be turned to d^2=3.33. That means that d=1.83g/cm^2. I hope that helps. Let me know if anything is unclear.

The scattering of light by a colloid is called the Brownian lighting, Tyndall effect, colloidal scattering, or aggregate reflection.

Answers

The correct answer is the Tyndall effect. This is also known as the Tyndall scattering. It is the light scattering by the particles in a colloid or in a suspension. This phenomenon is used to determine size and density of particles in colloidal matter.

A rigid cylinder contains a sample of gas at STP. What is the pressure of this gas after the sample is heated to 410 K?(1) 1.0 atm (3) 0.67 atm
(2) 0.50 atm (4) 1.5 atm

Answers

Answer:(4) 1.5 atm

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$(P_1V_1)/(T_1)=(P_2V_2)/(T_2)$

where,

$P_1$ = initial pressure of gas at STP= 1 atm

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas at STP = V L

$V_2$ = final volume of gas = V L

$T_1$ = initial temperature of gas at STP= 273K

$T_2$ = final temperature of gas = 410 K

Now put all the given values in the above equation, we get the final pressure of gas.

$(1atm* VL)/(273K)=(P_2* VL)/(410K)$

$P_2=1.50atm$

Therefore, the pressure of gas will be 1.50 atm.

To solve the problem, we assume the sample to be ideal. Then, we use the ideal gas equation which is expressed as PV = nRT. From the conditions of the gas sample, we calculate the pressure as follows: (NOTE: At STP 1 mol is equal to 22.4 L of a molecule)

P = nRT / V
P = (1 mol) (8.314 Pa m^3/ mol K) (298.15 K) / .0224 L
P = 110660 Pa or 1.0 atm

Thus, the answer is the value in option 1.

When one compound dissolves in water, the only positive ion produced in the solution is H3O+(aq). This compound is classified as(1) a salt
(2) a hydrocarbon
(3) an Arrhenius acid
(4) an Arrhenius base

Answers

Answer : The correct option is, (3) an Arrhenius acid

Explanation :

According to the Arrhenius concept, an acid is a substance which ionizes in the water to give hydronium ion $(H_3O^+)$ or hydrogen ion $(H^+)$ and a base is a substance which ionizes in the water to give hydroxide ion $(OH^-)$ .

When one compound dissolves in water, then only positive ion produced in the solution is $(H_3O^+)$ . This compound is classified as an Arrhenius acid.

Hence, the correct option is, (3) an Arrhenius acid

When one compound dissolves in water, the only positive ion produced in the solution is (aq). This compound is classified as an Arrhenius acid.

Calculate the number of moles of Al2O3 that are produced when 0.60 mol of Fe is produced in the following reaction: 2Al(s)+3FeO(s) = 3Fe(s)+Al2O3(s)

Answers

2 Al(s) + 3 FeO(s) = 3 Fe(s)+Al₂O₃(s)

3 moles Fe ------------> 1 mole Al₂O₃
0.60 moles Fe ------- > ?

moles Al₂O3 = 0.60 x 1 / 3

moles Al₂O₃ = 0.60 / 3

= 0.2 moles of Al₂O₃

hope this helps!

The number of mole of ${\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}$ produced is $\boxed{{\text{0}}{\text{.20 mol}}}$ .

Further explanation:

A balanced chemical reaction is a chemical reaction that has equal number of atoms of the different elements in the reactant as well as on the product side. The chemical equation is required to be balanced to follow the Law of the conservation of mass.

Stoichiometry of a reaction is used to determine the number of species present in the reaction by the relationship between the reactants and products. It can be used to determine the moles of a compound when the moles of another compound in the reaction are given.

The general reaction is as follows:

${\text{A}}+2{\text{B}}\to3{\text{C}}$

Here,

A and B are reactants.

C is the product.

One mole of Aand two moles of B react to form three moles of C. The stoichiometric ratio between A and B is 1:2, between A and C is 1:3 and between B and C is 2:3.

The given chemical reaction is as follows:

${\text{2\;Al}}\left({\text{s}}\right)\;+\;{\text{3\;FeO}}\left({\text{s}}\right)\to {\text{3\;Fe}}\left({\text{s}}\right)+{\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}\left({\text{s}}\right)$

According to the stoichiometry of the above-balanced chemical reaction, 2 moles of Al react with 3 moles of FeO to produce 3 moles of Fe and 1 mole of ${\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}$ .

Therefore, the ratio of the moles of Fe and ${\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}$ will be 3:1.

The formula to determine the number of moles of ${\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}$ is written as follows:

${\text{Number of moles }}\left({{\text{A}}{{\text{l}}_2}{{\text{O}}_{\text{3}}}} \right)=(1)/(3){\text{(number of moles of Fe}})$ …… (1)

Substitute 0.60 mol for number of moles of Fe in equation (1).

$\begin{aligned}{\text{Number of moles}}\left({{\text{A}}{{\text{l}}_{\text{2}}}{{\text{O}}_{\text{3}}}}\right)&=\frac{{\text{1}}}{{\text{3}}}\left({{\text{0}}{\text{.60 mol}}}\right)\n&={\text{0}}{\text{.20 mol}}\n\end{aligned}$

Hence, 0.20 mol of ${\mathbf{A}}{{\mathbf{l}}_{\mathbf{2}}}{{\mathbf{O}}_{\mathbf{3}}}$ is produced when 0.60 mol of Fe is produced in the reaction.
