What is the law of conservation of mass? How it is related to balancing chemical equations

Answers

Answer 1

Answer: The law of conservation of mass states that whatever goes in comes out the same. That's not the exact concept, but it'll help you remember it.

Here's another way of thinking about it.

Okay, so, we have:

Reactants ⇒ Products

The reactants form into products, but stay the same.

What does this mean?

This means that the mass is conserved. When mass is conserved, the energy is also conserved.

In other words, nothing has changed.

Now, lets relate that to balancing equations.

When you try to balance an equation, what is your goal? ⇒ To get the reactants to equal the products..? Right?

Ah, yes!

Now we have the exact meaning→→→→

The law of conservation of mass states that mass is always conserved in a chemical reaction.

Hope I helped! Please feel free to comment with questions! :)

Answer 2

Answer: Law that states that mass is neither created or destroyed in ordinary chemical and physical changes.

What is a significant advantage to the cell in having pyruvate dehydrogenase consist of a large

Answers

Answer: Pyruvate dehydrogenase consists of three enzymes: -Pyruvate dehydrogenase, Dihydrolipoyl transacetylase, and Dihydrolipoyl dehydrogenase. The short distance between these enzymes allows channeling of substrates which minimizes the side reactions.

Glycolysis or glycolysis (from glycos, sugar, lysis, breakdown) is the metabolic pathway responsible for oxidizing glucose to obtain energy for the cell. It consists of 10 consecutive enzymatic reactions that convert glucose into two molecules of pyruvate, which is able to follow other metabolic pathways and thus continue to deliver energy to the body

How do you tell if a reaction is endothermic or exothermic using only the written formula

Answers

You know if it's endothermic or exothermic by doing the enthalpy reaction. If the change of temperature is negative then it is exothermic, while positive is endothermic. If you get -22K then its exothermic, but if you get +22 its endothermic.

Describe the chemical process of fermentation.

Answers

Fermentation is a metabolic process. The molecules like glucose are breaks down anaerobically.

What is Fermentation ?

Fermentation is a metabolic process which converts sugars to alcohol, acids or gases. Fermentation is observed in bacteria,yeast cell and also in the muscle of animals. An Example is lactate fermentation which produces lactic acid.

What is Chemical process of fermentation ?

Fermentation is a chemical process in which molecules like glucose are breaks down anaerobically. Fermentation is chemical change. In chemical changea new substance is formed.

Thus, from above conclusion we can say that Fermentation is a metabolic process. The molecules like glucose are breaks down anaerobically.

#SPJ2

Answer:

Fermentation is a chemical process in which complex organic molecules are broken down into simpler compounds like ethanol. This process is catalyzed by certain enzymes. Enzymes are complex chemical catalysts produced by living cells. The sugars used for fermentation are often formed by enzymatic decomposition of starches from corn, potatoes, rice, or grain.
