Answer: The ability to be dissolved
Explanation:
Answer:
Explanation:
Hello,
In this case, given the described concept regarding the Avogadro's number, we can easily notice that 27.0 g of aluminium foil has 6.022x10²³ atoms as shown below based on the mass-mole-particles relationship:
Notice this is backed up by the fact that aluminium molar mass if 27.0 g/mol.
Best regards.
The value for this aqueous reaction at 298 k? a b↽−−⇀c dδ°=20. 46 KJ/mol is 9.91 mol. in equilibrium
<h3>What is an aqueous reaction in
equilibrium?</h3>
When a chemical reaction happens at the liquid state and the formation of reactant and product is the same then the reaction is known as an aqueous reaction in equilibrium denoted by K.
δG = − R T ln
R = universal gas constant 8.313
δG= 20. 46 kj/mol
T = 298 k or 24.4 in celcius.
substituting the value in the equation.
20. 46 kj/mol = 8.313 × 24.4 in celcius × K
K = 8.313 × 24.4 in celcius / 20. 46 kj/mo
k = 9.91 mol .
Therefore, The value of this aqueous reaction at 298 k? a b↽−−⇀c dδ°=20. 46 KJ/mol is 9.91 mol. in equilibrium

The correct answer would be the third option. In order for the equilibrium of the reaction to shift to the left, we must decrease the concentration of a reactant or increase the concentration of the product. This is based on Le Chatelier's principle which describes the effect on equilibrium of changes in concentration or pressure of a product or a reactant. Adding more product in a system, would disturbed the equilibrium thus it would cause to reestablish it by shifting the reaction to the left producing the reactants. This would also be the same when you decrease the amount of reactant in the system.
Answer: Temperature was kept as an independent variable to observe the changes in the heart beat.
Explanation:
Independent variable can be defined as the variable which can be changed to induce change in an dependent variable which is the outcome of the experiment.
According to the given situation, the temperature in which the frogs were kept changed to observe the changes in the rate of heart functioning. So, the temperature is the independent variable which changed before the experiment began.
