Making an apple pie is different from making lead iodide as lead iodide is a chemical compound and requires chemical process which is poisonous to eat while an apple pie is an eatable which is safe to eat.

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.

The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.

The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.

As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.

Therefore, in option C. the reaction rate decreases with a decrease in concentration.

Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.

Explanation:

Option A is correct. The statement that best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".

The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".

The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).

In conclusion, the statement best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".

Explanation:

The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:

Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.

In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.

The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.

Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

Answer:

Aerobic respiration is metabolic process in which food ( glucose) is metabolized ( in presence of oxygen) to derive large amount of energy ( in the form of ATP) through a series of three stages that is glycolysis, kreb cycle, and electron transport chain.

Anaerobic respiration another from of cellular respiration where food is broken down to derive energy in the absence of oxygen.

Alcoholic fermentation is a metabolic process by which sugar is converted into cellular energy ( in the form of ATP), ethanol, and carbon dioxide.

Lactic acid fermentation is a metabolic process by which glucose is converted into cellular energy and lactic acid.

Thus, the correct match is-

Aerobic respiration- A) The breakdown of food to create energy in the presence of oxygen.

Alcoholic fermentation- C) A process that converts sugars into cellular energy, ethanol, and carbon dioxide.

Anaerobic respiration- B) The production of energy without the presence of oxygen.

Lactic acid fermentation- D) A process that converts glucose into cellular energy and lactic acid.

Explanation:

Answer:

Aerobic respiration – The breakdown of food to create energy in the presence of oxygen

Alcoholic fermentation – A process that converts sugars into cellular energy, ethanol, and carbon dioxide

Anaerobic respiration – The production of energy without the presence of oxygen

Explanation: 150 lb * 1/6 = 25 lb

Chiara knows that weight is affected by gravitational pull. The weight of the dog on the moon is 25 lb. The correct option is A.

Gravitational pull is the force of gravitation that pulls all the objects towards themselves. The force of gravitation is different on different planets, and on the moon, the gravitational pull of the moon is lesser than the earth.

The weight of the dog on the earth is 150 lb

The weight of any object on the moon is 1/6th of the weight of any object on the earth.

So to calculate the weight of the object on the moon, we should multiply the given weight of the dog on the moon by 1/6 to get the result.

150 lb x 1/6 = 25 lb

Thus, the weight of the dog on the moon is 25 lb. The correct option is A.

Explanation:

The minnows is an abiotic factor in the ecosystem Hence option 3 is correct.

Ecosystem is defined as a structural and functional area of ecology where living things engage in interactions with one another and their surroundings. Ecosystem function refers to a system's capacity to directly or indirectly satisfy human wants for goods and services. Ecosystem functions are thought of as a subset of ecological processes and ecosystem structures.

The non-living elements of an ecosystem known as abiotic variables have an impact on their surroundings. Examples include temperature, light, and water in a terrestrial setting. Ocean currents and salinity are examples of abiotic components in a marine ecosystem.

Answer:

7.5 pounds per square-inch

At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.

The air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. than the pressure will be 7.5 pounds per square-inch.

At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.

As the altitude increases, the atmospheric pressure increases. It's actually the opposite: from the graph, we see that as the altitude increases (going towards right on the graph), the pressure decreases.

The atmospheric pressure is 14 pounds per square inch at sea level.If we take altitude=0, we see that the value of the pressure is 14 pounds per square inch. As the altitude approaches sea level, the atmospheric pressure increases.

As the altitude approaches sea level we see that the value of the pressure increases. The atmospheric pressure gets close to 14 pounds per square foot as the altitude continues to increase.The pressure is 14 pounds per square inch only when the altitude is 0 miles above sea level.

Therefore, The air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. than the pressure will be 7.5 pounds per square-inch.
