Area of a Rectangle A = l × b

Answer:

The temperature will be 384.7 K

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Having an initial state 1 and a final state 2, the following is true:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]

Solving:

[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]

T2= 384.7 K

The temperature will be 384.7 K

Answer:

2Mg + O2 → 2MgO

Explanation:

Answer:

Standard acid-base reaction in two stages:

Na2CO3 + HCl → NaHCO3 +NaCl

NaHCO3 + HCl → NaCl + CO2 + H2O

If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.

Explanation:

Answer:21 moles of PbCl2 formed

Explanation: 3Pb(NO3)2(aq) + 2AlCl3(aq) --> 3PbCl2(s) + 2Al(NO3)3(aq)

14 moles AlCl3 x 3 moles PbCl2/2 moles AlCl3 =21 moles of PbCl2 formed

The number of moles of PbCl₂ produced when 14 moles of AlCl₃ are consumed in the reaction is 21 moles

3Pb(NO₃)₂ + 2AlCl₃ —> 3PbCl₂ + 2Al(NO₃)₃

From the balanced equation above,

2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.

From the balanced equation above,

2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.

Therefore,

14 moles of AlCl₃ will react to produce = (14 × 3) / 2 = 21 moles of PbCl₂.

Thus, 21 moles of PbCl₂ were obtained from the reaction.

1. No reaction.

2. ZnCl₂ + H₂

3. CaCl₂ + H₂

Explanation:

1. Cu + HCl —> ___

From the reactivity series of metals, H is higher that Cu in the series and so, Cu can not displace H from solution.

Therefore, no reaction will occur.

2. Zn + HCl —> ___

Zn is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.

The balanced equation is given below:

Zn + 2HCl —> ZnCl₂ + H₂

3. Ca + HCl —> ___

Ca is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.

The balanced equation is given below:

Ca + 2HCl —> CaCl₂ + H₂

Answer:

19.32 g/cm³

Explanation:

The density will remain the same no matter how many times you cut the gold.  The density is g/cm³ or g/mL.  Density is essentially how many grams 1 mL of a compound weighs.

Answer:

[tex]\boxed {\boxed {\sf 19.32 \ g/cm^3}}[/tex]

Explanation:

Density is the mass per volume (g/mL or g/cm³). It is an intrinsic property. This means it is not dependent on the amount and all samples of the same substance have the same density.

Therefore, if a piece of gold has a density of 19.32 grams per cubic centimeter and it is cut in half, the two pieces will have the same density.

Explanation:

The Cl-Cl bond will react more readily because it has a lower bond energy than the C- H bond.

The bond energy refers to the energy required to break the bonds that links two atoms together in a molecule. It is equal to the energy that is evolved when the bond is formed.

In comparing the Cl-Cl bond with the C-H bond, we will find out that the Cl-Cl bond will react more readily because it has a lower bond energy than the C- H bond.

Mitochondria

Explanation:

Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.

The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of  3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.

In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.
