Which set of coefficients would balance the following equation?

Mg + AlCl3 → Al + MgCl2
A. 2Mg + AlCl3 → Al + 2MgCl2
B. 3Mg + 2AlCl3 → 2Al + 3MgCl2
C. Mg + 2AlCl3 → 2Al + MgCl2
D. 3Mg + 4AlCl3 → 4Al + 3MgCl2

Answers

Answer 1
Answer : B 3Mg + 2AlCl3 - 2Al + 3MgCl2

Explanation:

Reactants side Products side
Mg - 3 Mg - 3
Al - 2. Al - 2
Cl - 6 Cl - 6

Answer 2

The chemical equation  which is balanced according to law of conservation of mass  is 3 Mg + 2 AlCl₃ → 2 Al + 3 MgCl₂.

What is chemical equation?

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

What happens to the motion of an object if forces acting on the object are equal and balanced?

A. The object begins to move

B. The object begins to slow down

C. The motion of the object does not change

Answers

Answer:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.

So I think its C

You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.

Answers

Answer:

A and E.

Explanation:

 When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the  evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

Explanation:

Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

You can often tell by disturbances in the fossils bones. Maybe like dust or particles symbolize harm or mass extinction in a prehistoric animal or maybe even new fossils like some animals that went extinct recently like 200 years.

Explanation:

A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.

What are parts of a flower?

The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.

Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.

Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.

Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.

Thus the given parts are petal, stigma and stamen.

Why is it necessary to see a similar pattern of change in fossils from several places in order to conclude that an extinction happened?

Answers

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

One can learn a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.

What are fossils ?

Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.

Scientists use the fossil record to seek for patterns that may be used to infer which creatures are related to one another, how groups of organisms evolved through time, and how the Earth's climate affected the kinds of plants and animals that could survive for a very long time.

Thus,  a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity.
