Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

What is a chemical reaction?

A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.

The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.

Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.

Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Read the passage and examine the photos. Then, suggest two reasons that scientists think developing pollen grains made vascular plants the most successful plants that live on land.


Passage
These mosses are nonvascular plants that grow closely packed together in moist places. The sperm they produce for sexual reproduction must swim to a nearby plant that has an egg that the sperm may fertilize.
Seed plants, such as these conifers, are vascular plants that live in both moist and dry places. For sexual reproduction, conifers produce pollen grains that contain sperm that cannot swim. Conifers produce massive amounts of pollen grains that can be carried by wind.

Answers

Answer:

Vascular plants are successful due to better transportation for water, nutrients and reproduction.

Explanation:

I got it right at school and hope this helps you learn to STUDY.jk

According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Sperm can be more effectively and widely distributed for sexual reproduction, thanks to pollen grains.Vascular plants can reproduce without the need for a moist environment because they can make pollen grains.

What are Pollen grains?

Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.

They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.

Therefore, according to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Sperm can be more effectively and widely distributed for sexual reproduction, thanks to pollen grains.Vascular plants can reproduce without the need for a moist environment because they can make pollen grains.

O They have different masses and different electrical charges.
They have the same mass but different electrical charges.

Answers

Answer:

They have the same mass but different electrical charges.

Explanation:

Protons have a positive charge while neutrons have a neutral charge. Although they have different charges, they have the same amount of mass.

The protons and neutrons have the same mass but different electrical charges. THerefore, option (D) is correct.

What is a proton?

A proton is described as a stable subatomic particle, a chemical symbol with +1e elementary charge. The mass of the proton is approximately equal to the mass of the neutron but 1836 times the mass of an electron.

Protons and neutrons are jointly together termed "nucleons" each with masses of approximately one atomic mass unit (a.m.u.). There will be one or more than one proton present in the nucleus of an atom. There is an attractive electrostatic central force that holds the atomic electrons.

The number of protons in the atom is referred to as the atomic number and is expressed by the symbol Z. Since each element in the periodic table has a unique number of protons, determines the chemical characteristics of the element.

As the neutrons present in the nucleus of an atom are neutral and do not carry any charge while the protons are positively charged.

How do the products of chemical reactions compare to their reactants? Question 5 options: The products usually weigh more than the reactants. The products often have completely different properties than the reactants. The products usually have more atoms than the reactants. The products are usually more toxic than the reactants.

Answers

Answer:

The products often have completely different properties than the reactants.

Explanation:

In a chemical reaction, the products are often completely different from the reactants.

When chemical reactions takes place, the species rearranges to form new bonds and to attain stability.

Therefore, the new products formed usually have completely different properties when compared to the reactants.

Also, in chemical reactions, mass is always conserved. The mass of the products and reactants are usually the same.

How many grams of H2SO4 are needed to react with 78.86 grams of AI(NO3)3 ?
I

Answers

Answer:

53.18 grams of H₂SO₄ are needed to react with 78.86 grams of Al(NO₃)₃.

Explanation:

The balanced reaction between Al(NO₃)₃ and H₂SO₄ is:

2 Al(NO₃)₃ + 3 H₂SO₄ → Al₂(SO₄)₃ + 6 HNO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reagents are required:

Al(NO₃)₃: 2 molesH₂SO₄: 3 moles

Being the molar mass of the elements:

Al: 27 g/moleN: 14 g/moleO: 16 g/moleH: 1 g/moleS: 32 g/mole

then the molar mass of the reactants are:

Al(NO₃)₃: 27 g/mole + 3*(14 g/mole + 3*16 g/mole)= 213 g/moleH₂SO₄: 2*1 g/mole + 32 g/mole +4*16 g/mole= 98 g/mole

Then, by reaction stoichiometry, the following reagent mass amounts are required:

Al(NO₃)₃: 2 moles* 213 g/mole= 436 g H₂SO₄: 3 moles*98 g/mole= 294 g

Then you can apply the following rule of three:  If by stoichiometry 436 g of Al(NO₃)₃ react with 294 g of H₂SO₄, 78.86 g of Al(NO₃)₃ with how much mass of H₂SO₄ will it react?

[tex]mass of H_{2} SO_{4} =\frac{78.86 grams of Al(NO_{3} )_{3}*294gramsofH_{2} SO_{4} }{436 grams of Al(NO_{3} )_{3}}[/tex]

mass of H₂SO₄=53.18 g

53.18 grams of H₂SO₄ are needed to react with 78.86 grams of Al(NO₃)₃.

Using the three words below (cell wall, cell membrane and animal cell) construct your own sentence using what you have learned about plant and animal cells. PLEASE HELP ME IT WILL BE

Answers

Answer:

Explanation:

Both eukaryotic and prokaryotic cells have a cell membrane, which defines the limit between the environment surrounding the cell and the cell itself.

Eukaryotic cells can be either animal cells or plant cells. Plant cells, apart from the membrane, are surrounded by a cell wall that is thick and conformed by carbohydrates and peptides. This cell wall makes the cell resistant and gives it its shape. Animal cells, on the other hand, do not have cell walls, they only have the cell membrane, that regulates the entrance of nutrients and the exit of metabolic products.

The diagram below shows what happens to an atom of uranium-235 when bombarded by a neutron. Which isotope is represented by X in the diagram?

Answers

Answer:

X represents barium - 141 nucleus.

Written as: (141, 56) Ba

Explanation:

In nuclear fission reaction, due to the fact that the process produces more neutrons, a nuclear chain reaction can possibly occurr. Now, a chain reaction is a one whereby the material that begins the reaction will also be one of the products and it can start another reaction.

Now, for the nuclear chain reaction for the fission of uranium-235, its nucleus absorbs a neutron after which it splits into a krypton - 92 nucleus and a barium - 141 nucleus. Thereafter it releases three more neutrons.

Thus, X is the image represents barium - 141 nucleus.
