For the following hypothetical reaction:

3A + 12B --> 3C

How many moles of B will you need to convert 5 moles of A into as many moles of C as possible?

Answers

Answer 1

Answer:

20

Explanation:

You need 4 times the amount of B, compared to a (there is a 3A:12B which reduces to 1:4), so 4 times 5 is 20.

Write out a correctly formatted hypothesis that describes how the amount of hydrogen gas produced with be affected by the concentration of acid.

Answers

When creating mixture the amount of hydrogen gas is directly related to the concentration of the acid mixture, the higher the concentration level The more hydrogen gas would be produced.

To solve such this we must know the concept of acid and base reaction. Therefore, the concentration of acid decides the concentration of hydrogen gas evolved.

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

The overall shape of a plant cell is most directly related to which of its parts?

Answers

Cell wall is the answer

Cell wall is a unique structure found in some organisms.

Answer: Cell wall

Explanation: Cell wall is a unique structure found only in some specific organisms like plants, bacteria, fungi etc. The cell wall in plants is predominantly made up of a polysaccharide called CELLULOSE. This carbohydrate confers upon the cell "rigidity".

The cell wall is an additive material including the cell membrane that coats the external part of the cell of plants, hence, it gives plant cells their characteristic shape. The cell wall contributes to the overall flexible but rigid shape of the plant cell, protecting the cell against physical or chemical stresses.

do Plants and animals create energy the same way?

Answers

Answer:

Yes

Step By Step Explanation:

Plants extract energy from food molecules the same way animals do — by cellular respiration.

Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called "photosynthesis". ... Plants get their energy in form of starch whereas animals get it in form of glycogen. Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.

Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.

Hopes This Helps

Plants extract energy from food molecules the same way animals do — by cellular respiration. When plants do cellular respiration, they produce carbon dioxide and use oxygen just like animals do.

If substances B and C are both in the gas phase and are at the same energy level, which of the two substances will need to have more energy transferred out in order to change to the liquid phase? Substance B or Substance C? Explain your answer below.
For Science

Answers

Answer:

Substances can change phase—often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.

The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance. It requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance, represented as ΔHfus. Some ΔHfus values are listed in Table 10.2 “Enthalpies of Fusion for Various Substances”; it is assumed that these values are for the melting point of the substance. Note that the unit of ΔHfus is kilojoules per mole, so we need to know the quantity of material to know how much energy is involved. The ΔHfus is always tabulated as a positive number. However, it can be used for both the melting and the solidification processes as long as you keep in mind that melting is always endothermic (so ΔH will be positive), while solidification is always exothermic (so ΔH will be negative).

Describe how a frog grows. Why do you think the eggs are found in the water? Where do you think fertilization happens?​

Answers

The process of fertilization occurs externally in frogs.

Stages of lifecycle

A full growth of frog occurs when it passes through five stages of its life cycle. During a frog's metamorphosis, an egg will hatch and a tadpole appear in which the back legs emerge first, then front legs, and finally it become a full grown adult frog.

Eggs of frog

A frog's eggs are found in water because they do not have a hard protective shell like birds and reptiles. The frog's eggs are covered with a glycoprotein, which helps to keep the eggs moist so that's why the frog lays its eggs in water in order to prevent them from drying.

Fertilization

In most species of frogs, fertilization occurs externally. The male frog grabs the female's back and fertilizes the eggs as the female frog releases the eggs. Those eggs which receives the sperm will fertilized so we can conclude that the process of fertilization occurs externally in frogs.
