Argument 1
The water in the puddle that Claire observed evaporated. The highest temperature was 32°C (90°F). Since the puddle was there in the morning and gone later in the day, it must have evaporated.



Argument 2
The water in the puddle that Claire observed evaporated. Since the highest temperature was 32°C (90°F), we know that it was a warm day. When water gets hot, it can change from liquid to gas. This is called evaporation. I think the water became so warm that it became water vapor (gas), and that’s why the puddle was gone by the afternoon.

Answer: C2H4 + 3O2 > 2CO2 + 2H2O

Explanation:

The law of conservation of mass has been given as the mass cannot be created nor be destroyed in a chemical reaction. The law of conservation of mass has equal weight of the reactants and the products.

The mass of following reactions can be given as:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

12g + 4(2)g   =   16g

20g = 16g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

3(18)   = 3(2) + 3(32)

54g = 102g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

2(23) + 36.5 = 58.5 g

81.5g = 58.5g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

The reaction that has been following the law of conservation of mass has been reaction 1. Thus, option 3 is correct.

Which of the following equations follows the Law of Conservation of Mass?

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

C2H4 + 3O2 > 2CO2 + 2H2O

The mass of the following reactions can be given:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.

Answer:

d)

Explanation:

The answer is D as the new substances formed are always on the right of the equations. They are called Products.

hope it helps.

no problem

New substances formed during a chemical reaction are indicated- "on the right side of the equation and are called products."

The right side of the equation indicates new compounds created during a chemical reaction, and these substances are referred to as products in the correct response. This is due to the fact that during a chemical reaction, reactants change to create new substances, which are the reaction's products. This transformation is represented by the chemical equation, which lists the reactants on the left and the products on the right. The direction of the reaction is shown by the arrow in the equation, demonstrating how reactants are changed into products.

The following factors make the other options incorrect:

The statement "On the left side of the equation and are called products" is untrue since products are created after a reaction, not before it occurs. They cannot therefore be indicated on the left side of the equation.

Reactants are the beginning compounds that engage in the reaction, not the newly created substances, hence the statement "On the right side of the equation and are called reactants" is likewise false. To demonstrate the reactants' presence before the reaction takes place, they are mentioned on the left side of the equation.

The answer "On the left side of the equation and are called reactants" is also untrue since reactants are substances that exist independently of reactions; they do not arise from them. In order to indicate their presence before the reaction occurs, they are listed on the left side of the equation.

In summary, new substances formed during a chemical reaction are indicated on the right side of the equation and are called products, while reactants are listed on the left side to show their presence before the reaction.

Answer:The force that the person needs to apply to accelerate the sledgehammer is 14N.

What is a Force?

A force is an influence that can cause an object's motion to alter. A force can cause a mass item to change its velocity, or accelerate. Intuitively, force may be characterized as a push or a pull. A force is a vector quantity since it has both magnitude and direction. Its SI unit is Newton.

Force = Mass × Acceleration

Given that the mass of the sledgehammer is 3.5 kgs, the sledgehammer is needed to be accelerated at a rate of 4 m/sec².

Mass = 3.5 kgs

Acceleration = 4 m/sec²

Now,  the net force that the person needs to apply to accelerate the "sledgehammer" at a rate of 4.0 m/sec² is,

Force = Mass × Acceleration

        = 3.5 kg × 4 m/sec²

        = 14 N

Hence, the force that the person needs to apply to accelerate the sledgehammer is 14N.

Answer:

The same thing (B - The second option listed)

Explanation:

The genetic materials of the offspring of new plants grown from cuttings and that of the parent plant are usually the same.

The type of reproduction at play here is asexual. Asexual reproduction involves only a single parent and ensures that both the resulting offspring and the parent share the same genetic material.

The process of asexual reproduction involves mitosis - the division of vegetative cells. Both the parent cells and the daughter cells of mitosis are identical - phenotypically and genotypically.

Answer:

The answer is Equal amount of genetic material and identical.

method 3 for number 2

method 2 for number 1 , 3 , 4

Answer:

The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Explanation:

If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.

The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.

As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.

Seafloor spreading is simply the idea that volcanic activity forms new oceanic crust.

In order to understand what seafloor spreading is in depth, it's important that we understand a few concepts and terms.

If we can understand these terms, we can easily comprehend what seafloor spreading is.

If we take a look at the attached image, the image represents what occurs during sea floor spreading. First we must note that sea floor spreading occurs in mid ocean ridges. Because we know that mid ocean ridges is a continuous range of underwater volcanoes , we know that the mid ocean ridges are formed on divergent boundaries (as volcanoes under water are formed by divergent boundaries) . As we know, at divergent boundaries, the tectonic plates move away from each other. As the tectonic plates move away from each other, magma pushes itself up and as the magma touches the water it cools and hardens forming the crust as shown in the image. (Note that this takes several years to happen)
