Answer:
<h2>8.92 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4.75 g
volume = 0.5325 cm³
We have
We have the final answer as
<h3>8.92 g/cm³</h3>
Hope this helps you
Answer:
The list of elements from increasing electronegativity: Calcium < magnesium < chlorine < argon < boron.
Explanation:
In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.
Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.
D. oxygen is used to break down glucose into energy
Explanation:
During respiration, oxygen is used to break down glucose into energy:
C₆H₁₂O₆ + O₂ → CO₂ + H₂O + energy
In the process of respiration, oxygen gas combines with glucose to liberate energy.
- Respiratory system in the body is responsible for the metabolic break down of food to provide energy for the working of the human body.
- Chemical energy in glucose is broken down to produce other forms of energy most especially heat.
- The by product is usually carbon dioxide and water vapor.

Evaporation occurred between the reaction of the hydrochloric acid and the arsenic group because there is a formation of gas. A
liquid is cooled if condensation exceeds evaporation. This is because the cooling of the liquid decreases the kinetic energy of the
molecules. Their movement is being restricted by the colder temperature. The
molecules tend to be closer with each other. Also, because of their restricted
movement, the liquid may turn into solid due the colder temperature. An example
of this is the cooling of liquid water by placing it into the refrigerator into
solid water (ice).</span>
