When a covalent or an ionic bond is formed a chemical change has occurred. Which of these is not associated with a chemical change?A) The atoms of the substance produced have been rearranged.
B) The substances produced are identical to the substances that reacted except that they're isomers.
C) The total mass of the reacting substances is the same as the total mass of the substance produced by the reaction.
D) The chemical properties of the substances produced by the reaction are different from those of the reacting substances.

Answers

Answer 1

Answer:

Answer: B) The substances produced are identical to the substances that reacted except that they're isomers.

Explanation: Chemical change is a change in which atoms of the reactants are rearranged ,thus leading to formation of new products.

The new substances formed are different compounds from the original reactants and thus they have different properties.

$2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)$

This is an example of chemical reaction in which the bond between chlorine molecule is broken and a new bond between sodium and chlorine gets formed.

$NaCl$ formed is an ionic compound whereas chlorine is a covalent compound and sodium is a metal.

Answer 2

Answer: The answer is B). The total mass and the atom numbers of reacts and products are the same in the reaction. But that does not mean the production are identical to the reactants.

Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals. Which term do scientist use to describe these orbits

Answers

Planets in our solar system do not revolve around the sun in perfect circles. They revolve in the elliptical orbits.

What is the solar system?

The solar system consists of the planet's satellites, as well as numerous comets, asteroids, and meteoroids, as well as the interplanetary medium.

Planets in our solar system do not revolve around the sun in perfect circles. They revolve in the elliptical orbits.

Hence, option D is correct.

Answer:

It is most likely the word elliptical.

Explanation:

Usually the term elliptical refers to the oval-like shape of a substance or path of an object. The question states, "Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals." Because the planets orbit around the sun in an oval-like path, those orbits can be described as elliptical. Scientists also normally use this word to describe the same thing; Therefore, your answer is elliptical.

Which air pressure reading is likely an indicator of clear weather?a. 900 mb
b. 950 mb
c. 1000 mb
d. 1050 mb

Answers

1050 mb of air pressure is likely an indicator of clear weather. The correct option among all the options given in the question is option "d". In reality, higher pressure is mostly associated with clear and good weather while stormy or bad weather is often associated with low air pressure.

A quantity of gas has a volume of 0.20 cubic meter and an absolute temperature of 333 degrees kelvin. When the temperature of the gas is raised to 533 degrees kelvin, what is the new volume of the gas? (Assume that there's no change in pressure.) A. 0.0006 m3
B. 0.2333 m3
C. 0.2146 m3
D. 0.3198 m3

Answers

pV = n R T => if pressure is constant => p = n R T / V = const. => p / n R = T/ V = const. => T / V = const. T1 = 333 K T2 = 533 K V1 = 0.2 m3
T1 / V1 = T2 / V2 => V2 = V1 x T2 / V2 = 0.2 x 533 / 333 = 0.32 m^3 answer D is correct
