Answer:
It does not always retain the properties of the substances that make it up
Explanation:
The chemical formula of the ionic compound is XY₂.
<h3>Ionic compounds</h3>
- Ionic compounds are compounds which are formed from the combination of negatively charged and positively charged ion.
- Positively charged ions are formed by loss of electrons
- Negatively-charged ions are formed from gain of electrons
<h3>Formation of ionic compounds</h3>
During the formation of the ionic compound between an ion X that has a charge of 2+ and ion Y has a charge of 1-, two negatively charged ions of Y are required to form a neutral ionic ionic compound when they react with X.
The chemical the formula of the ionic compound they form is as follows;
X²⁺ + 2Y⁻ ---> XY₂
Therefore, the chemical formula of the ionic compound is XY₂.

Answer:
(a) 
(b)
(c) 
Explanation:
Hello,
(a) In this case, with the given formula we easily compute the mass of gold contained in the sovereign as shown below:
(b) Now, by knowing the density of gold and copper, 19.32 and 8.94 g/cm³ respectively, we compute each volume, by also knowing that the rest of the coin contains copper:
(c) Finally, the volume is computed by dividing the total mass over the total volume containing both gold and copper:
Best regards.
The key enzyme in the regulation of the citric acid cycle is citrate synthase. It functions in the mitochondria.
<h3>Citrate synthase and cellular respiration </h3>
Cellular respiration is a series of reactions that produce ATP by using the energy stores in the chemical bonds of foods.
Cellular respiration is divided into glycolysis, the citric-acid cycle and oxidative phosphorylation.
Citrate synthase is an enzyme found in the mitochondrial matrix, which is involved in the citric acid cycle.

Answer:
A region on top of a mountain is cooler than at the base.
Explanation:
Pressure and temperature have direct relationship with each other. With the decrease in pressure, the temperature decreases and vice versa. When the air rises in the atmosphere, the pressure starts to fall. The low pressure at the peak of the mountains tends to cause the fall in temperature. It is because of this reason that it is cooler at the top of the mountain while the temperature is less cool in the foothills.
