Answer:
D
Explanation:
A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. Solids molecules stay close to eachother maintaining its shape meaning it is in a ordered pattern.
In commensalism the smaller partner benefits from the relationship, with no fitness effect on the host. There are fitness gains for both partners in mutualism, and a parasite benefits by exploiting but not directly killing its host.
hope this helps ^^
Answer:
Adding more of gas C to the system
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>
1) Adding more of gas C to the system:
Adding more C gas will increase the concentration of the products side. So, the reaction will be shifted to the left to attain the equilibrium again.
2) Heating the system:
Heating the system will increase the concentration of the reactants side as the reaction is endothermic. so, the reaction will be shifted to the right to attain the equilibrium again.
3) Increasing the volume:
has no effect since the no. of moles of gases is the same in both reactants and products sides.
4) Removing some of gas C from the system:
Removing some of gas C from the system will decrease the concentration of the products side. So, the reaction will be shifted to the right to attain the equilibrium again.
<em>So, the right choice is: Adding more of gas C to the system.</em>

Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.
