What happens when a solid is dissolved in a liquid

jolli1 [7]

Answer:

B. first level consumers.

Explanation:

The first level consumers are also the primary consumers. They are the animals that depends or rely on plants to transform chemical energy into carbohydrates and sugar.

Primary consumers are mostly herbivores. They feed on plant matter by which they derive their nutrition. They have special enzymes that helps to convert plant materials into substances needed for their body.

So, the first level consumer takes plant matter and convert them into useful food materials for their own nutrition.

The second level consumers depend on the first level consumers for nutrition.

Which energy carries are formed by light dependent reaction

ad-work [718]

Answer: "In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom."

Select the coefficients necessary to balance each equation. Choose a coefficient for every compound.

ivolga24 [154]

Answer:

See below

Explanation:

2C2H6 + 7O2 = 4CO2 + 6H2O

2C2H2 + 5O2 = 4CO2 + 2H2O

A lot of this is trial and error. I start from left to right. For the first reaction, you had

C2H6 + O2 = CO2 + H2O

You have 2 carbons on the left so you can try adding a 2 in front of the carbons on the right and keep going from there. Now you have

C2H6 + O2 = 2CO2 + H2O

You now have 2 C on each side. C2 is the same as 2C.

The next step is to look at the hydrogens on the left. You have 6 so you need 6 on the right. You can add a 3 in front of the H on the right. The H already has a subscript of a 2 so having the 3 in front will now make it 6H. You now have this

C2H6 + O2 = 2CO2 + 3H2O

So your C are equal (2 on each side) and your H is equal (6 on each side). All that is left is the O. So far you have 2 on the left but you have 7 on the right (4 from the 2CO2 and 3 more from 3H2O). Since you have an even number on one side and an odd number on the other, there is no way to make this work. So it's time to start over.

My next step was to put a 2 in front of C2H6 and keep going as we did above. Start with this

2C2H6 + O2 = CO2 + H2O

You have 4 C on the left. So you need to add a 4 in front of CO2 to get 4 C on the right. Now you have this

2C2H6 + O2 = 4CO2 + H2O

Now on the left you have 12 H (2 in front times the 6 subscript on the H). You need to have 12 on the right. We can get that by putting a 6 in front of the H2O ( again the 6 in front times the 2 subscript of the H is 12 total). You have this now

2C2H6 + O2 = 4CO2 + 6H2O

You now have 4 C on both sides, 12 H on both sides. All that is left now is the O.

On the right side, you have a total of 14 ( 8 from the 4CO2 and 6 from 6H2O). So you'd need to add 7 in front of the O2 to make it 14.

You're done. 4 C on both sides, 12 H on both sides and 14 O on both sides.

The second equation I just did the same process.

Why were more than 2 total atoms needed to create this compound?

Ksivusya [100]

Answer:

Compound is like a community and needed more than 2 atoms.

Explanation:

1 atom

2 atoms= 1 molecule

3 atoms (either of same or different elements)= compound

Under conditions of "feasting", the body favors oxidation/utilization of which source for energy production

mezya [45]

During feasting, there is an increase in the supply of carbohydrates, fats and proteins in the body. Since these macronutrients are in excess, carbohydrates and proteins are utilized or oxidized as a source for energy production. On the otherhand, fats are accumulated as the rate of oxidation of this source does not increase during feasting.
