What is 1500 in scientific notation

Answers

Answer 1

Answer: To form the value of 1500 in scientific notation, it is
1.    By simply moving the period which separates the whole numbers from the decimal numbers between 1 and 5.
2.    Thus, it then becomes 1.5
3.    Next, is you have to count how many moves the period made from its point of origin hence, for this value is 3
4.    Therefore, the scientific notation for the number is 1.5 x 10^3

A solution that is at equilibrium must be(1) concentrated (3) saturated(2) dilute (4) unsaturated

Answers

Answer:

(3) saturated

Explanation:

Hello,

In this case, a solution that is at equilibrium must be (3) saturated as at the equilibrium, the entire solute is completely dissolved into the solvent, so no leftovers are present. Unsaturated solutions are not at equilibrium since there is a portion of solvent that is not contributing to equilibrium. Concentrated solutions are not at equilibrium since they could have more solution than allowed into the solvent.

Best regards.

A solution that is at equilibrium must be saturated.

Which Pair Of Compounds Are Isomers?1) CH3CH2CH3 and CH2CHCH3
2) CH2CH2 and CH3COCH3
3) Ch3OCH3 and CH3COCH3
4) CH3COCH3 and CH3CH2CHO

I'd like to know the steps to answering this question. Thanks!

Answers

The correct pair of compounds that are isomers is CH₃COCH₃ and CH₃CH₂CHO and the correct option is option 4.

Isomers are compounds that have the same molecular formula but different structural arrangements or connectivity of atoms.

Among the given options, the pair of compounds that are isomers is CH₃COCH₃ (acetone) and CH₃CH₃CHO (propanal). Both compounds have the molecular formula C₃H₆O, but they differ in their structural arrangement.

Acetone is a ketone, with a carbonyl group located in the middle of the carbon chain, while propanal is an aldehyde, with the carbonyl group located at the end of the carbon chain.

These structural differences result in distinct chemical properties and reactivities of the compounds.

Thus, the ideal selection is option 4.

The Pair Of Compounds that Are Isomers are CH3COCH3 and CH3CH2CHO. The answer is number 4. Isomers have the same formula but different structures. In number 4, both compounds contains three carbon atoms, one oxygen and 6 hydrogen atoms that makes them isomers.

A compound is formed when 171.2 g of carbon reacts with 28.8 g of hydrogen. What is the mass percent of hydrogen in the compound

Answers

Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:

mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%

Answer:

For Edmentum/Plato users, the correct answer is A. 14.4%
