The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dioxide gas. Write the balanced chemical equation

Answers

Answer 1

Answer:

C6H12O6 —> 2C2H5OH + 2CO2

Explanation:

The equation for the reaction is given below:

C6H12O6 —> C2H5OH + CO2

We can balance the equation above as follow:

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

Now the equation is balanced.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection

Which type of selection is shown in the graph above? A. Disruptive selectionB. Stabilizing selectionC.

Answers

The anwser is A Disruptive selection

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

Nitrogen has an atomic number of 7. Its atomic mass is 14. Nitrogen has _____.

seven electrons
seven neutrons
seven electron shells
23 neutrons
14 electrons

Please help (:

Answers

Seven electrons. The atomic number of a element is also the amount of protons and electrons it has.
As atomic Number is number of protons Or number of electrons so
N has 7 electrons
Neutrons= Mass no.- Atomic Number
= 14-7
N has 7 neutrons
N doesn’t have 7 electron shells because shell 1 can hold 2 electrons and shell 2 can hold 8 electrons
It doesn’t have 23 neutrons and 14 electrons

So, Seven Electrons and seven neutrons is correct

Answers

Following the scenario, the spheres of the earth that interacts would be the geosphere, the hydrosphere, and the biosphere.

Think about "The Law of Conservation of Mass" (In a chemical change, the total mass of the new substances is always the same as the total mass of the original substances.) Why might it be difficult to demonstrate this law in chemical changes where one or more of the products is a gas?

Answers

Answer:

The Law of Conservation of Mass states matter cannot be created/destroyed in a chemical reaction

It is hard to prove the law because the gas molecules move out the area quickly, at a higher speed than liquid or solid particles.

If their appears to be a loss in mass, it is because of the above, and that is why it may be difficult to demonstrate this 'law'.
