Reaction rate is the speed with which reactants are converted to products in a chemical reaction. True or False?

Answers

Answer 1

Answer: True. Except that it is per unit of time. Units are important in order for our chemical reactions speed to be determined properly.

Answer 2

Answer:

Final answer:

The statement is true; reaction rate in chemistry refers to the speed at which reactants are transformed into products. Its rate is influenced by factors like concentration, temperature, and the presence of catalysts.

Explanation:

"Reaction rate is the speed with which reactants are converted to products in a chemical reaction," as stated above, is correct. In chemistry, the term Reaction Rate is used to describe how rapidly or slowly changes occur in a chemical reaction. It essentially provides information about how quickly reactants are transformed into products. Factors such as concentration, temperature, and presence of catalysts can influence the rate of a reaction.

How does calcium and potassium react differently with water and why

Answers

calcium with water:
When a metal reacts with water( cold water or hot water) then the products formed are metal hydroxide and hydrogen gas.

Metal + steam --------> Metal hydroxide + Hydrogen

Calcium reacts with cold water to form calcium hydroxide and hydrogen gas:

potassium with water.

Potassium reacts violently with cold water to form potassium hydroxide and hydrogen gas:

2K(s)+ 2H2O(l) --------> 2KOH(aq) + H2(g) + heat.
In this reaction so much heat is produced get hydrogen gas formed catches fire and burns explosively.

What is the process of breaking down glycogen without the presence of oxygen?

Answers

Answer:

anaerobic glycolysis

In my knowledge, this would be called anaerobic respiration – anaerobic meaning without oxygen and the respiration process is through glycolysis, the breaking down of glucose to form (with generalisations) 2 ATP molecules and lactic acid (with probably some other bits and pieces). I thought this was a biology concept? :D

One problem with using pesticides to control insects on crops is that the insects can develop resistance to the chemicals. How is this similar to the overuse of antibiotics?

Answers

Answer:

Explanation:

Overuse of antibiotics leads to bacteria's resistance against our drugs. This is increasing at an alarming rate and the reason is that overuse of antibiotics kills bacteria that lack the "resistance" gene or gene that can help them survive the antibiotics (similar is the case for insects that die to insecticides). But, some bacteria can have random mutations in their gene that can help them survive the antibiotic (similar is the case for some insects that can survive the insecticide), thus the surviving bacteria give rise to next generation of bacteria that are resistant to the given antibiotic (similar to how insects that survive the insecticide give birth to new insects that are resistant to insecticide too). Soon, every generation adds new antibiotic resistant bacteria (or new insecticide resistant insects in the case of insects) which is dangerous for all of life on this planet. Therefore, both are similar in the sense that new generations of these organisms will be resistant to our weapons against them.

Can Sodium be used to distinguish between cyclobutanol and butanoic acid

Answers

Answer:

$\boxed{\text{No}}$

Explanation:

Na reacts with all OH groups to produce hydrogen.

The reaction with cyclobutanol is shown below.

The reaction with butanoic acid is

$\rm CH_(3)CH_(2)CH_(2)COOH\xrightarrow{\text{Na}} CH_(3)CH_(2)CH_(2)COO^(-) + H_(2)$

Both compounds release bubbles of hydrogen, so you can't use sodium to distinguish between them.

Every substance melts at 0 degrees Celsius and boils at 100 degrees Celsius.True
False

Answers

False, that only applies to water as far as I know, but I know for a fact that gold does not melt at 0 degrees Celsius

Hello! It is true that water boils at 100% C, however, this is not true for any substance. Take steel, for instance, steel would take MUCH higher temperatures to melt, and to boil. As it says "ANY SUBSTANCE" this would be false.

I hope this helped!

I am, yours most sincerely,
