What else can I help you with?
Does heat transfer with the same temperature?
No. When two bodies or regions are at the same temperature, equilibrium is already reached & no transfer of heat occurs.
What is the order of a reaction if the graph is curve horizontal?
If the graph of a reaction's concentration versus time is a horizontal curve, it indicates that the concentration of the reactant is not changing over time, suggesting that the reaction has reached completion or is at equilibrium. This typically corresponds to a zero-order reaction, where the rate of reaction is constant and independent of the concentration of the reactants. In such cases, the rate remains constant until the reactants are depleted.
What is the importance of geometric progression?
It appears in any system where the growth (or decrease), at any stage is dependent on the level reached. Common examples: Compound interest (surely, nobody, except elementary maths pupils, uses simple interest!). Depreciation. Radioactive decay. Also, Pyramid selling schemes - until they hit the buffers of saturation!
In Suppose you have experimented to test the effects of temperature on seed germination as outlined in the study guide. If you do not reject your null hypothesis what conclusion can be reached?
If you do not reject your null hypothesis in the experiment testing the effects of temperature on seed germination, you can conclude that there is no significant effect of temperature on the germination rates of the seeds tested. This suggests that variations in temperature did not lead to measurable differences in the germination outcomes. Consequently, any observed changes in germination can be attributed to random chance rather than the temperature conditions applied in the study.
Suppose you have experimented to test the effects of temperature on seed germination as outlined in the study guide. If you do not reject your null hypothesis what conclusion can be reached?
If you do not reject your null hypothesis in the experiment testing the effects of temperature on seed germination, you can conclude that there is insufficient evidence to suggest that temperature significantly affects seed germination rates. This means that any observed differences in germination may be due to random chance rather than a temperature effect. Consequently, the results indicate that temperature may not be a critical factor influencing seed germination in the conditions tested.
The reaction mgf2s mg2 aq 2f-aq has reached saturation with concentrations mg2 2.8 x 10-5 and f- 1.5 x 10-2 what is the value of ksp for mgf2 at this temperature?
6.4 x 10-9
How can one tell if a reaction has reached equilibrium?
All motion ceases
The reaction alpo4s al3 plus aq plus po43 has reached saturation with concentrations al3 plus equals 1.14 x 10-10 and po43- equals 1.14 x 10-10 what is the value of ksp for alpo4 at this temperature?
1.3 x 10-20
What does it mean to say that a reaction has reached equililibrium?
When a reaction has reached equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but the reaction is still ongoing.
When a solution has gained as much solute as it can at a given temperature it has reached the point of?
When a solution has gained as much solute as it can at a given temperature, it has reached the point of saturation. At this point, no more solute can dissolve in the solvent, and any excess solute will remain undissolved in the solution.
What temperature is saturation reached?
it doesn't depend on the temperature but depends on how much water was evaporated
The reaction pbbr2s pb2 plus aq plus 2br-aq has reached saturation with concentrations pb2 plus equals 2.5 x 10-3 and br- equals 5.0 x 10-2 what is the value of ksp for pbbr2 at this temperatur?
6.3 x 10-6
What happens if solute is diluted?
As you add solute to a dilute If_you_add_solute_to_a_dilute_solution_what_does_the_solution_become, the solution becomes more concentrated until the solution has reached its saturation concentration. At the saturation concentration, no more solute can dissolve into the solution.Read more: If_you_add_solute_to_a_dilute_solution_what_does_the_solution_become
When a substance has reached the point where it can no longer dissolve a material's it has reached?
saturation
Solution where more solute will dissolve?
Such a solution is called is called unsaturated solution. In such a solution the salt dissolved hasn't reached the level of saturation. Also, more solute can be dissolved if temperature is increased after reaching the saturation.
The reaction pbbr2s pb2 aq 2br-aq has reached saturation with concentrations pb2 2.5 x 10-3 and br- 5.0 x 10-2 what is the value of ksp for pbbr2 at this temperature?
The formula for the solubility product constant (Ksp) for a saturated solution of PbBr2 is Ksp = [Pb2+][Br-]^2. Substituting the given concentrations into the formula, we get Ksp = (2.5 x 10^-3)(5.0 x 10^-2)^2 = 6.25 x 10^-5. Therefore, the value of Ksp for PbBr2 at this temperature is 6.25 x 10^-5.
What is a property of a reaction that has reached equilibrium?
the rate of the forward reaction is greater than the rate of the reverse reaction.
