Molly inflates a beach ball to a volume of 8 liters in her air-conditioned house where
the temperature is 19°C. Later that day, Molly takes the beach ball to the beach. The
temperature at the beach was 33°C, and the air pressure at the beach is the same as
it was at the house.
What will happen to Molly's beach ball when she is at the beach?

Answer:

soft water can leath with soap whiles hard water cannot be leathers with soap

Answer:

Hard water is water with excess calcium and magnesium, while soft water lacks harsh minerals that can hurt your body.

Explanation:

Also, in hard water, soap is not so effective (little or no foam) and in soft water soap is easily effecive (foams easily).

The observation in the illustration remains in accordance with the law of conservation of mass assuming that moisture is present in the container.

The law state that mass can neither be created nor destroyed. However, mass can be converted from one form to another.

In this case, the ion was placed in a container of pure oxygen. Assuming that moisture is present, iron reacts with oxygen to form rust according to the following equation:

[tex]4Fe + 3O_2 + 6H_2O --- > 4Fe(OH)_3[/tex]

The rust formed will weigh more than the initial weight of the iron.

Without the presence of moisture, one can effectively conclude that the observation violates the law of conservation of mass.

Organelles are the components of the cells with various functions and roles. The correct blanks are chloroplast, cell wall and vacuole, vacuoles, and mitochondria.

The organelles are the cell components that have well-defined structures and functions to perform the designated task in the cell activity. Chloroplast is the organelle that converts solar energy into chemical energy through photosynthesis.

The cell wall and the vacuoles provide the structural framework and shape of the cell. The vacuoles also store food pigments in the cell. The mitochondria of the cell convert the food source into energy like ATP.

Therefore, the correct blanks are chloroplast, cell wall and vacuole, vacuoles, and mitochondria.

Yes, at high temperature and pressure (1011 kpa), diamond can change directly (sublime) into gaseous form.

Diamond is a solid form of the carbon element with its atoms arranged in a crystal structure called diamond cubic.

Diamond has some interesting properties, which is written below;

A diamond interacts with oxygen in the air and disappears to form carbon dioxide.

Thus, at high temperature and pressure (1011 kpa), diamond can change directly (sublime) into gaseous form.

Using the given formula, the density of the material is 2.015 g/mL

From the question, we are to determine the density of the material

From the given formula

Density = Mass / Volume

And from the given information,

Mass = 65.5 g

and volume = 32.5 mL

Putting the parameters into the equation,

Density = 65.5/32.5

Density = 2.015 g/mL

Hence, the density of the material is 2.015 g/mL.

Explanation:

The partial pressure of the hydrogen gas, if the water vapor pressure is 3.17kPa is 91.83 kPa.

Dalton's law of gas states that total pressure of the mixture of gas is equal to the sun of the partial pressure of the individual gas.

Given that,

Total pressure of hydrogen gas = 95 kPa

Partial pressure of water vapor = 3.17 kPa

Partial pressure of hydrogen gas will be calculated as:
Partial pressure = 95 - 3.17 = 91.83 kPa

Hence required partial pressure is 91.83 kPa.

Answer:

744.0 mL

Explanation:

Formula obtained from Charles Law :

⇒ [tex]\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }[/tex]

===============================================================

Given :

⇒ V₁ = 780.0 mL

⇒ T₁ = 30 °C = 303 K

⇒ T₂ = 16 °C = 289 K

=============================================================

Solving :

⇒ V₂ = 780 × 289 / 303

⇒ V₂ = 225420 / 303

⇒ V₂ = 744.0 mL (approximately)
