What specifically determines how much energy is available in a molecular
HACTEHA [7]

C  The number and types of bonds within the molecule.

Explanation:

In a molecule, the number and types of bonds present determines the amount of available energy therein.

When bonds are broken or formed, energy is usually released.

  • Elements combine with one another in order to attain stability in this state.
  • Through this process, they form bonds by attraction.
  • Where atoms exchange their valence electrons by losing or gaining it, electrovalent bonds form.
  • In covalent molecules, electrons are usually shared between atoms.
  • An attraction result from this type of interaction.
  • The bond formed stores energy in the process.
  • When bonds are broken, energy is usually released. The energy accrues when the bond was being formed.
  • In molecules, we have covalent bond.

Sergio039 [100]

Answer:

The accuracy can be improved by making sure no external force is applied, i.e the marbles should accelerate under gravity only during each trial.

Explanation:

Accuracy is a term used to describe the relationship between a measured value to the real value. When a measured value is accurate, it implies that there is little or no error in the value; thus it is equal to the real value or very close to it.

Since this experiment is to determine the speed with which the marble roll down the plane, they should ensure uniform acceleration through out the  trials. The marbles should be allowed to move under the influence of gravity only without applying any external force.

2. The ions in an ionic compound separate from each other when
kkurt [141]

Answer:

A. when dissolved in water

Explanation:

Water is an extremely polar molecule, meaning it has a positive end a negative end. When an ionic compound is dissolved, the positive pole of water will be attracted to the negative ion and attach itself to it. The same goes for the positive ions. That's how water breaks down ionic compounds
