Answer 1

Answer:

d)

Explanation:

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

Answer 2

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.

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

Answers

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.

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

Answers

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.
