An aqueous solution made from solid sodium carbonate (Na2CO3) would be basic.

The best description for an aqueous solution made from solid sodium carbonate (Na2CO3) is:

Your answer: basic

Sodium carbonate is a salt of a strong base (sodium hydroxide) and a weak acid (carbonic acid). When it dissolves in water, it undergoes hydrolysis and forms sodium hydroxide (NaOH) and carbonic acid (H2CO3). Since sodium hydroxide is a strong base and carbonic acid is a weak acid, the resulting solution will be more basic than acidic, making the aqueous solution basic.

The specific heat of olive oil (2 J/g·°C) is less than that of water (4.18 J/g·°C). This indicates that olive oil requires less heat energy to raise its temperature compared to an equal mass of water.

To describe the specific heat of olive oil compared to water, we can use the given information that it takes approximately 420 J of heat to raise the temperature of 7 g of olive oil by 30°C.

The specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of 1 gram of the substance by 1 degree Celsius (or Kelvin).

In this case, we can calculate the specific heat of olive oil by dividing the amount of heat (420 J) by the mass (7 g) and the temperature change (30°C):

Specific heat of olive oil = (Amount of heat)/(Mass * Temperature change)

                          = 420 J / (7 g * 30°C)

                          ≈ 2 J/g·°C

Comparing this specific heat value to the specific heat of water (which is approximately 4.18 J/g·°C), we can conclude that the specific heat of olive oil (2 J/g·°C) is less than the specific heat of water. This means that olive oil requires less heat energy to raise its temperature compared to an equal mass of water.

The half-life of a certain radioactive isotope is 5 days. After 3 days, we need to estimate the percentage of the original amount of the isotope that remains.

To find the percentage remaining, we can use the formula: Percentage remaining = (1/2)^(number of half-lives) * 100%
In this case, since 3 days have passed and the half-life is 5 days, we can determine the number of half-lives as: Number of half-lives = 3 days / 5 days = 0.6 half-lives

Plugging this into the formula, we get: Percentage remaining = (1/2)^(0.6) * 100%
Using a calculator, we find that (1/2)^(0.6) is approximately 0.796, so: Percentage remaining = 0.796 * 100% = 79.6%
Therefore, approximately 79.6% of the original amount of the isotope released by the explosion remains 3 days after the explosion.

The correct answer is option 2: 2 atm.

To solve this problem, we can use the combined gas law, which states that the ratio of the initial pressure (P1) to the final pressure (P2) is equal to the ratio of the initial volume (V1) to the final volume (V2).

According to the problem, the initial volume (V1) is 3.0 ml, and the final volume (V2) is 6 ml. Since the temperature is constant, the combined gas law simplifies to:

P1 / P2 = V1 / V2

Substituting the given values into the equation, we have:

P1 / P2 = 3.0 ml / 6 ml

Simplifying further, we get:

P1 / P2 = 0.5

To find the new pressure of the gas (P2), we need to determine the reciprocal of the ratio obtained:

P2 = 1 / (P1 / P2) = 1 / 0.5 = 2

Therefore, the new pressure of the gas is 2 atm.

So, the correct answer is option 2: 2 atm.

Explanation:

If the temperature on Earth starts to lower then a "positive feedback" will start to begin trying to make Earth heat up.

Clouds can trap that heat from the Sun therefore the clouds wrap Earth in a blanket. Therefore clouds have both a cooling effect as well as a warming effect.

Solar radiation makes it from our sun to the Earth and through the atmosphere. Solar radiation refers to electromagnetic waves or light. Solar radiation comes in three major classes: visible light, infrared light, and ultraviolet light.

The full electromagnetic spectrum features 7 types of light from lowest frequency to highest: radio waves, microwaves, infrared light, visible light, UV light, X-rays, and γ-rays. The ozone layer in the atmosphere prevents the passage of UV light through it.

The human eyeball can only detect visible light. The ultraviolet, "beyond violet," is invisible. The solar radiation coming from the sun can increase the temperature of the earth. The clouds prevent them to reach the surface. Therefore, it is positive feedback.

a unique set of solubility curves is used to illustrate the relationship between a substance's solubility and temperature or pressure. solubility curves are employed in sectors like food, pharmaceuticals, and chemical manufacture.

A graph illustrating the relationship between a substance's solubility and temperature or pressure is called a solubility curve. The solubility (measured in grammes of solute per 100 grammes of solvent) is often plotted versus temperature (or pressure) on the x-axis in solubility curves, which are particular to each solute and solvent system. The solubility of a substance changes with temperature or pressure, and this fact makes solubility curves crucial in the study of chemistry and related subjects. They can be used to forecast how a solution will behave under certain situations, such as whether a solute will dissolve or precipitate out of solution.

Answer: 24g

Explanation: bc

The freezing point of the solution is -11.8 °C.

The boiling point of the solution is 103.31 °C.

To determine the freezing point of the solution, we can use the equation:

ΔTf = Kf * m

where:

ΔTf is the freezing point depression,

Kf is the cryoscopic constant (for water, Kf = 1.86 °C/m),

m is the molality of the solution (moles of solute per kilogram of solvent).

First, let's calculate the molality (m) of the solution:

Molar mass of ethylene glycol (C2H6O2):

C = 12.01 g/mol

H = 1.01 g/mol (x 6) = 6.06 g/mol

O = 16.00 g/mol (x 2) = 32.00 g/mol

Total molar mass = 12.01 g/mol + 6.06 g/mol + 32.00 g/mol = 50.07 g/mol

Number of moles of ethylene glycol (C2H6O2) = mass / molar mass

Number of moles = 30.8 g / 50.07 g/mol = 0.615 mol

Mass of water = volume x density = 96.6 mL x 1.00 g/mL = 96.6 g

Now, let's calculate the molality:

Molality (m) = moles of solute / mass of solvent (in kg)

Molality = 0.615 mol / 0.0966 kg = 6.36 mol/kg

Now we can calculate the freezing point depression (ΔTf):

ΔTf = Kf * m

ΔTf = 1.86 °C/m * 6.36 mol/kg = 11.8 °C

To find the freezing point of the solution, subtract the freezing point depression from the freezing point of pure water (0 °C):

Freezing point = 0 °C - 11.8 °C = -11.8 °C

To determine the boiling point of the solution, we can use the equation:

ΔTb = Kb * m

where:

ΔTb is the boiling point elevation,

Kb is the ebullioscopic constant (for water, Kb = 0.52 °C/m),

m is the molality of the solution (same value as calculated before: 6.36 mol/kg).

ΔTb = 0.52 °C/m * 6.36 mol/kg = 3.31 °C

To find the boiling point of the solution, add the boiling point elevation to the boiling point of pure water (100 °C):

Boiling point = 100 °C + 3.31 °C = 103.31 °C

In the titration of 50.0 ml of 0.020 M aqueous salicylic acid with 0.020 M KOH(aq), the pH after the addition of 55.0 ml of KOH(aq) can be calculated.

Salicylic acid is a weak acid with a pKa value of 2.97.  After the addition of 55.0 ml of KOH(aq), the solution will contain an excess of OH- ions due to the neutralization reaction between salicylic acid and KOH. The OH- ions will react with the weak acid, converting it to its conjugate base, salicylate. The pH of the resulting solution will depend on the relative concentrations of the acid and its conjugate base, as well as the pKa value.

To calculate the pH, we need to determine the concentrations of the acid and its conjugate base. The initial moles of salicylic acid can be calculated using the given volume and concentration. Since the acid and base react in a 1:1 ratio, the moles of KOH added will be equal to the moles of salicylic acid at the equivalence point.

Next, we calculate the moles of salicylic acid remaining after the reaction. Since 55.0 ml of KOH(aq) is added to the initial 50.0 ml of salicylic acid, the total volume becomes 105.0 ml. We subtract the moles of KOH added from the initial moles of salicylic acid to find the moles of salicylic acid left.

Using the moles of salicylic acid and its conjugate base, we can determine their concentrations. The concentration of the acid is obtained by dividing the moles of acid remaining by the final volume of the solution. The concentration of the conjugate base is determined in a similar manner.

Finally, we can calculate the pH using the Henderson-Hasselbalch equation:

pH = pKa + log10([conjugate base]/[acid])

Substituting the calculated values, we can find the pH of the solution after the addition of 55.0 ml of KOH(aq) to the titration of salicylic acid.
