The ______ force is equal to the weight of the fluid displaced by an object. gravitational friction buoyant
Tju [1.3M]
Buoyant



Buoyancy is the ability to float in fluids.
Gravity is the force of all objects attracted to one.
Friction is the force caused when two objects rub against each other causing them to slow

<span>Archimedes principle explains that the magnitude of that force is proportional to the difference in the pressure between the top and the bottom of the column, and</span> is also equivalent to the weight of the fluid that would otherwise occupy the column, i.e. the displaced fluid.

What effect does a) increasing the total pressure and b) increasing the temperature have on the equilibrium H2(g) CO2(g) D H2O(g
Rama09 [41]

Answer:

d. a) no change in the equilibrium and

   b) equilibrium shifts towards products.

Explanation:

Hello.

In this case, for the reaction:

H_2(g) +CO_2(g) \rightleftharpoons H_2O(g)+ CO(g);\ \ \ \ \Delta H=41.2kJ/mol

Which is endothermic due to the positive enthalpy of reaction. In such a way, based on the Le Chatelier's principle which states that increasing the temperature of an endothermic chemical reaction shifts the equilibrium towards products as heat is understood as a reactant, we can see, this is the case.

Moreover, since the change in the number of gaseous moles in the chemical reaction (coefficients balancing the reaction) is 0 (1+1-1-1), we can see that increasing the total pressure does not have any effect over equilibrium.

Therefore answer is d. a) no change in the equilibrium and b) equilibrium shifts towards products.

Best regards!
