Balanced chemical reaction:
4C₅H₉O + 27O₂ → 20CO₂ + 18H₂O.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
Type of reaction is combustion.
Combustion is reaction with oxygen.
Organic compound reacts with oxygen and produce carbon dioxide and water.
Answer:
I think its B im not sure
but i hope this helps
1.Magnesium (Mg) has two electrons in its outer shell. Mg will <span>try to give two electrons to another atom (because the Mg is metal).
</span>2. When an atom loses electrons, it becomes <span>positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)</span>
Answer:
E. The number of moles of solute in both solutions is the same.
Explanation:
The dilution of a solution consist in increase the volume of solution decreasing, thus, the concentration of the solution. The moles of solute doesn't change in a dilution process.
Thus, when a solution is diluted, the relationship of the number of moles of solute in the more concentrated initial volume of solution to the number of moles of solute in the less concentrated final volume of solution is that:
E. The number of moles of solute in both solutions is the same. TRUE.

Answer:
8J
Explanation:
From the question, the gravitational stored energy is 8J.
So Mgh=8J.
The kinetic energy is ?
When we use the law of conservation of energy, as the apple is moving and about to it the ground, it has 0m speed.
Which means that the potential energy at rest i.e when the apple is on the ground is zero. When the apple is getting to the ground, KE +PE is conserves.
At the top of the tree, the Apple has zero potential energy because velocity is zero at rest and on hitting the ground, the apple has kinetic energy.
So, the maximum Kinetic energy is 8J.
