A solution with a pH less than 7 is considered _____, a solution with a pH of 7 is considered _____, and a solution with pH greater than 7 is considered _____. The pH is a measure of a solution\'s _____, hydrogen concentration oxygen concentration action concentration hydrogen ion concentration A buffer is a chemical that keeps the pH of a solution neutral. resists a large or dramatic change in pH adds hydrogen wins to a solution when the pH decreases. removes hydrogen ions from a solution when the pH increases. A chemical reaction takes place when: A chemical bonds are formed. chemical bonds are broken. chemical bonds are rearranged. electrons are transferred between molecules. All of the above. _____ the rate of reactions, and decreasing the temperature generally _____ the rate of reactions. Which of the following is not a property of enzymes? They increase the rate of a reaction, They are not consumed in the reaction, They change the products of a reaction, They are biological catalysts.

Solution

1 a solution with ph less than 7 is acidic ....a solution with ph =7 is neutral and a solution with ph greater than 7 is basic .

2.answer is D. the ph is a measure of solutions hydrogen ion concentration.

3. aanswer is B buffer is a chemical that resists a large or dramatic change in ph.

fill in the blanks

increase in temperature generally increases the rate of reaction and decreasein temperature generally decreases the rate of reaction.

4. answer is E . all the things said happen in a chemical relation.

WHICH OF THE FOLOWING IS NOT PROPERTY OF ENZYMES

answer is C ... ENZYMES DO NOT CHANGE THE PRODUCTS IN THE REACTION
