1 answer:
gladu [14]3 years ago
4 0

Answer:

c. Many of their bonds are C-C and C-H

Explanation:

The majority of bonds in  carbohydrates and lipids( being an organic compound) are C-C and C-H. Like glucose, fructose or galactose ,etc.

These bonds are strong and do require a lot of energy to break. Thus, a lot of energy are required to break carbs and lipids into simpler compounds.Therefore, carbohydrates and lipids have high potential energy.

The correct answer is c.

Strike441 [17]
When a solvent has as much of the dilute dissolved in it as possible, then it is saturated.

If you were to heat the water, its capacity would increase and would then be super-saturated because it has more dissolved in it than possible as room temp.

Since there is no heating being done, the water is just saturated.

Hope that helps!

Which polyatomic ion is found in the compound represented by the formula NaHCO3?
olga nikolaevna [1]

Answer is (2) - hydrogen carbonate


<em>Explanation:</em>


NaHCO₃ is an ionic compound which is made from Na⁺ and HCO₃⁻ ions. The decomposition is

NaHCO₃ → Na⁺ + HCO₃⁻


Among the resulted ions, Na⁺ is a monatomic ion while HCO₃⁻ is a polyatomic ion.


<em>Polyatomic ions mean ions which are made of two or more different atoms.</em>


HCO₃⁻ is made from 3 atoms as H, C and O. The name of HCO₃⁻ ion is bicarbonate or hydrogen carbonate.

Based on molecular orbital theory, the bond orders of the H—H bonds in H 2 , H 2 + , and H 2 - are _________, respectively
vodka [1.7K]

Answer:

H2-1

H2+-1/2

H22- zero

Explanation:

Bond order= Bonding electrons-antibonding electrons/2

In H2, there are two bonding electrons and no antibonding electrons. In H2+ there is only one bonding electron and no antibonding electron while in H22- there are two bonding and two antibonding electrons respectively.

Identify the type of reaction: 2AgCl + BaBr2 -&gt; 2AgBr + BaCl2
Marta_Voda [28]

Answer:

C

Explanation:

Just look at the reactants.

2AgCl + BaBr2

The first reactant is made of 2 elements.

The second reactant is made of 2 elements.

It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like

2MgO ===> 2Mg + O2

is a decomposition.  One compound breaking down into 2 elements Mg and O.

It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like

C3H8 + 5O2 ==> 3CO2 + 4H2O

That would be what a combustion looks like

It can't be a single replacement. They look like

Mg + CuO ===> Cu + MgO

There are elements on both sides of the reaction.

that leaves a double replacement which I wrote about how you distinguish it.

List three ways in witch the water reaches the atmosphere
meriva
Three ways water reaches from earth to atmosphere are
1. direct evaporation from the water bodies like sea,river,oceans
2. moisture from the land(you must have seen land dries out)
3.moisture from the plant(small capillaries from the plants sucks water from land n goes to atmosphere in form of vapour from leaves)
