Based on the given compound formula Al2X3, the most likely element for X is: D. Cl. The compound with the formula Al2X3 suggests that there are two aluminum atoms and three atoms of a particular element represented by "X".

To determine which element "X" could be, we need to consider the valency of aluminum and the other elements. Aluminum has a valency of +3, which means it can bond with three other atoms to complete its valence shell. Among the given options, sulfur (S) and chlorine (Cl) have a valency of -2, while phosphorus (P) and hydrogen (H) have a valency of -3 and +1, respectively.

Therefore, the correct answer would be D. Cl, as it can form a compound with Al in the ratio of 2:3 by gaining three electrons to attain a noble gas configuration. The compound would be Al2Cl3, which is aluminum chloride, a well-known and stable compound. The other options (A. P, B. S, C. H) do not form stable compounds with aluminum in a 2:3 ratio.

As substances travel from the small intestines to the large intestine, the H+ ion concentration would increase. This is because the pH of a solution is determined by the concentration of H+ ions. A lower pH indicates a higher concentration of H+ ions, while a higher pH indicates a lower concentration of H+ ions.

In this case, the pH of the small intestines is 7.5, which suggests a lower concentration of H+ ions compared to the pH of 5.5 in the large intestine. The decrease in pH from the small intestines to the large intestine indicates an increase in the concentration of H+ ions.

The change in pH along the digestive tract is primarily due to the secretion and absorption of various substances in different regions. The large intestine, for example, contains bacteria that can produce acids as byproducts of their metabolism, leading to a lower pH.

Overall, the transition from the small intestines to the large intestine results in an increase in the H+ ion concentration, leading to a lower pH in the large intestine compared to the small intestines.

Answer:

86.91757 amu

Explanation:

From the question given above, the following data were obtained:

Isotope A (rubidium-85)

Mass of A = 84.91179 amu

Abundance of A = 72.17%

Atomic mass of rubidium = 85.47 amu

Isotope B (rubidium-87):

Abundance of B = 27.83%

Mass of B =?

The actual mass of rubidium-87 can be obtained as follow:

Atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]

85.47 = [(84.91179 × 72.17)/100] + [(Mass of B × 27.83)/100]

85.47 = 61.28084 + (Mass of B × 0.2783)

Collect like terms

85.47 – 61.28084 = Mass of B × 0.2783

24.18916 = Mass of B × 0.2783

Divide both side by 0.2783

Mass of B = 24.18916 / 0.2783

Mass of B = 86.91757 amu

Thus, the mass of rubidium-87 is 86.91757 amu

The work done by the gas is -0.0124 L·atm and the heat absorbed from the thermostat is also -0.0124 L·atm.

To find the work done by the gas and the heat absorbed from the thermostat, we can use the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat absorbed by the system minus the work done by the system.

First, let's calculate the change in volume. The gas is allowed to double in volume, so the final volume will be 2 times the initial volume. The initial volume is 0.0124 dm^3, so the final volume will be 2 * 0.0124 dm^3 = 0.0248 dm^3.

Next, we need to calculate the work done by the gas. The work done by a gas expanding or contracting against a constant external pressure can be calculated using the equation: work = -P * ΔV, where P is the constant external pressure and ΔV is the change in volume.

In this case, the external pressure is 1.0 atm and the change in volume is (0.0248 dm^3 - 0.0124 dm^3) = 0.0124 dm^3. So, the work done by the gas is: work = -1.0 atm * 0.0124 dm^3 = -0.0124 L·atm.

To find the heat absorbed from the thermostat, we can rearrange the first law of thermodynamics equation: heat = change in internal energy + work. Since the problem states that the gas is an ideal gas, we can assume that the internal energy change is only due to changes in temperature, which means the change in internal energy is zero.

Therefore, the heat absorbed from the thermostat is equal to the work done by the gas: heat = -0.0124 L·atm.

Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy. Pure monosaccharides, such as glucose, attract water.

An animal's body breaks down carbohydrates and converts them into simple sugar such as glucose. Glucose in the form of energy is carried through the blood and delivered to every cell of the body.

Carbohydrates are an important compound of all life on this planet. Both plants and animals utilize carbohydrates as a source of energy to keep their body functioning at the most basic level.

Carbohydrates fulfill needs by helping in the synthesizing of other chemicals and giving structure to cells within the body. Carbohydrates are carrying out normal functions such as growth, movement, and metabolism.

Carbohydrates store energy in the form of starch and provide either simple or complex sugars. Polysaccharides, give a steady supply of energy while sugars, monosaccharides, and disaccharides, supply quick energy on dissolving.

Explanation:

The mass percent of the sucrose solution is 46% which is made by mixing 8.37 grams of sucrose into water until the solution has a mass of 17.9 grams.

Given, Mass of sucrose = 8.37 g

Mass of solution = 17.9 g

We can calculate the mass of water as follows:

Mass of water = Mass of the solution - Mass of sucrose= 17.9 g - 8.37 g= 9.53 g

We can then use the formula for mass percent to calculate the answer:

Mass percent = (Mass of solute / Mass of solution) × 100%

Substitute the values of the mass of sucrose and mass of solution in the above formula,

Mass percent = (8.37 / 17.9) × 100%= 46.81%

Therefore, the mass percent of the sucrose solution is 46%.

Answer:

Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).

Explanation:

:)

Flashpoints for flammable liquids are at 100°F. Lower flash points allow for easier ignition of liquids. A liquid's flash point is the lowest temperature at which a concentrated enough layer of vapor accumulates on top of its surface to allow for ignition.

A liquid that is flammable has a flash point* below 37.8 ° C (100 ° F). A flammable liquid has a flash point that ranges from 37.8 to 93.3° C (100 to 200° F), which is above the standard working temperature. Flammable liquids emit a vapor that, at standard working temperatures, is easily ignitable.

The substance ignites more readily the lower the flash point. For instance, petrol is more flammable than ethylene glycol and has a flash point of about -40 degrees C (-40 °F).
