Which of the following will experience induced magnetism most easily

Answers

Answer 1

Answer:

The statement, Sunlight is a form of electromagnetic energy, is true. The answer is letter A. Electromagnetic energy is a form of radiant energy that released by electromagnetic radiation. One example of an electromagnetic radiation is the visible light. And visible light can be radio waves, infrared light and X - rays. The rays of the sun are a form of visible light. It has an electromagnetic radiation of UV (ultra violet) rays. That is why the radiation at day is greater than at day due to sun’s rays.

How can states of matter be helpful in life?

Answers

you will know that there is a long period where the temperature stays the same before any change in state of matter, and will not appear stupid in conversations

States of matter is useful in life because without solids we would have no cups shoes or tables and without liquids we wont be able to survive because we need water aka LIQUID to survive and without gases we wouldnt be able to breathe.

Na+ + Cl– NaCl Which statement best describes the relationship between the substances in the equation?

Answers

Answer : The number of sodium ions is equal to the number of formula units of salt.

Explanation : In the given reaction of NaCl the statement which describes it the best is that the number of sodium ions is found to be same along with the formula units in the product side.

$Na^(+)$ + $Cl^(-)$ ----> NaCl.

Its clear from the equation that one mole of Na and one mole of Cl combines together to give the product, which is one mole of NaCl. The number of ions on both the sides are equal.

The correct answer for the question that is being presented above is this one: "The number of sodium ions is equal to the number of formula units of salt." The statement that best describes the relationship between the substances in the equation is that the number of sodium ions is equal to the number of formula units of salt.

The equation shows the reaction between zinc metal and hydrochloric acid.Zn(s) + 2HCl(aq) mc014-1.jpg ZnCl2(aq) + H2(g)

What is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid?
5.05 g
10.1 g
182 g
682 g

Answers

The balanced chemical reaction is written as:

Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)

We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:

5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2

Therefore, the correct answer is the second option.

Answer:

B. 10.1g

Molecules of 1-bromopropane and 2-bromopropane differ in(1) molecular formula(2) structural formula(3) number of carbon atoms per molecule(4) number of bromine atoms per molecule

Answers

Answer: (2) structural formula

Explanation:-

The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.

1-bromopropane and 2-bromopropane are position isomers which have same molecular formula but different position of the functional groups attached.

The chemical formula for both the compounds 1-bromopropane and 2-bromopropane is $CH_3CH_2CH_2Br$ . Thus both have same molecular formula , 3 carbon atoms per molecule and 1 bromine atom per molecule.
