Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the expe

rimental record. Use complete sentences to explain the trend you predicted. You do not have to determine exact values for time; just describe the trend you would expect (increase or decrease) and why it occurs

Answer:

See explanation

Explanation:

The rate of reaction depends on on the concentration of reactants. As the concentration of reactants increases, the rate of reaction increases likewise.

If we look at the table, we will discover that the concentration of the thiosulphate is increasing because the volume of water added is decreasing. As such, the rate of reaction increases simultaneously.

Since the rate of reaction increases, the time taken for the cross to disappear decreases steadily. Hence, the values in the last column of the table decreases steadily.

What is the oxidation state of each element in the species Mn(ClO4)3?
gayaneshka [121]
The oxidation state of the compound Mn (ClO4)3 is to be determined in this problem. For oxygen, the charge is 2-, the total considering its number of atoms is -24. Mn has a charge of +3. TO compute for Mn, we must achieve zero charge overall hence 3+3x-24=0 where x is the Cl charge. Cl charge, x is +7.

For changing potential energy; When you drop a book, gravitational potential energy is transformed into kinetic energy. Your car transforms the chemical potential energy stored in gasoline into the kinetic energy of the car's motion.

For Kinetic Energy; kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a car.

Explain why the column of a fractional distillation apparatus should be aligned as near to the vertical as possible
____ [38]
<span><span>The column of a fractional distillation apparatus should be aligned vertical to get better separation because the column is essentially longer. It will prevent channeling in the column. </span>Therefore column efficiency will be higher if it is as vertical as possible instead of tilted.<span> Distillation is a process used to separate a mixture of two (or more) components. In a typical </span>fractional distillation, a liquid mixture is heated in the distilling flask and the process begins.</span>

Which characteristics are common to the three isotopes of hydrogen?
allsm [11]
D should be the correct answer.  isotopes are atoms that have the same atomic number (number of protons) but different atomic masses (number of protons and neutrons).  isotopes also have the same number of electrons since atoms need to have equal numbers of protons and electrons to not be considered ions.  Since the number of protons determines the chemical properties of the atom, we can say that all isotopes have the same chemical properties due to the fact that all isotopes have the same atomic number.

I hope this helps.  Let me know in the comments if anything is unclear.
