Answers

The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 1 x 10^6 microliters (mL) in 1 L. Multply 35 by 1000/1x10^6

35 kL (1000 liters/ 1 kL) (1 x 10^6 mL/ 1 L) = 3.5 x 10^9 microliters

l. Given the balanced equation representing a reaction:What occurs during this reaction?1) Energy is absorbed as bonds are broken.2) Energy is absorbed as bonds are formed.3) Energy is released as bonds are broken4) Energy is released as bonds are formed.

Answers

1) energy is absorbed and bonds are broken

This is due to two reasons
1. The breaking of bonds requires and input energy. The formation of bonds is a release on energy. As bond breaking requires energy, it is only natural that once of the answers would involve the absorption of energy.
2. O2 is the covalent bond between two oxygen molecules. When these molecules are separated the bond is broken. As such the answer must be 1

What particles in an atom are involved in chemical reactions

Answers

Answer: Electrons

Explanation: In chemical reactions, elements and compounds change in order to form different substances. This changes can be:

1. oxidation state: which is define as the charge of the atom

2. bonding: atoms in a compound are bonded, this bonds can break so atoms rearrange to form different substances

In this changes electrons are involve. The charge depends on the amount of negative charge of electron respect to positive charge of proton in nucleus which remain the same, otherwise we would be talking about nuclear reactions.

Also, bonding depends on the electrons that atoms can give, receive or share to form ionic or covalent bonds.

Explanation:

What is a disadvantage of using a structural model to show a chemical compound? Structural models provide minimal three-dimensional information. Structural models do not identify the number and type of each atom. Structural models cannot distinguish between single, double, and triple bonds. Structural models cannot distinguish between different isomers of a compound.

Answers

The answer is the first: that structural models provide minimal three-dimensional information. This is because the ball-and-stick model cannot show the actual size of the atoms depicted in the model. You also cannot see the actual bond lengths between the atoms. This, then, limits the accuracy of the model and fails to precisely portray how the chemical compounds being shown are like in all actuality. Thus, though you do see a three-dimensional picture of the chemical compound, this picture is not completely accurate and is not scaled to size.

Answer: A - Structural models provide minimal three-dimensional information.
