This is an example of Innovation.
<h3>What is an
Innovation?</h3>
Innovation is the application of concepts in a way that results in the creation of new products or services or enhances the provision of existing ones. Innovation is defined as "a new or altered entity realizing or dispersing value" by ISO TC 279 in the standard ISO 56000:2020. Others have different definitions, but they all place an emphasis on the novelty, development, and dissemination of concepts or technologies.
The creation of more efficient goods, procedures, services, technology, works of art, or business models, which innovators then make available to consumers, governments, and society as a whole, is a common way that innovation occurs. Innovation and invention are not the same thing, but they are related.

Answer:
C. at low temperature and low pressure.
Explanation:
- <em>Le Châtelier's principle </em><em>states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>
<em />
<em>2CO₂(g) ⇄ 2CO(g) + O₂(g), ΔH = -514 kJ.</em>
<em></em>
<em><u>Effect of pressure:</u></em>
- When there is an increase in pressure, the equilibrium will shift towards the side with fewer moles of gas of the reaction. And when there is a decrease in pressure, the equilibrium will shift towards the side with more moles of gas of the reaction.
- The reactants side (left) has 2.0 moles of gases and the products side (right) has 3.0 moles of gases.
<em>So, decreasing the pressure will shift the reaction to the side with higher no. of moles of gas (right side, products), </em><em>so the equilibrium partial pressure of CO (g) can be maximized at low pressure.</em>
<em></em>
<u><em>Effect of temperature:</em></u>
- The reaction is exothermic because the sign of ΔH is (negative).
- So, we can write the reaction as:
<em>2CO₂(g) ⇄ 2CO(g) + O₂(g) + heat.</em>
- Decreasing the temperature will decrease the concentration of the products side, so the reaction will be shifted to the right side to suppress the decrease in the temperature, <em>so the equilibrium partial pressure of CO (g) can be maximized at low temperature.</em>
<em></em>
<em>C. at low temperature and low pressure.</em>

Answer: 4.86 x 10⁻³ mole.
Explanation:
- The number of moles can be calculated using the relation; n = mass / molar mass.
- n is the number of moles, mass is the mass of the substance in g (m = 0.5 g), and molar mass of NaBr = 102.894 g/mole.
- n = mass / molar mass = (0.5 g) / (102.894 g/mole) = 4.86 x 10⁻³ mole.
If matters mix and it doesn’t make a material it’s called physical change. But, if maters are mixed and they do make a material it’s called chemical change.
