4Ga + 3S2 → 2Ga2S3 1. How many grams of Gallium Sulfide would form if 20.5 moles of Gallium burned?
In this case, for the given chemical reaction, we can notice there is a 4:2 molar ratio between the burned moles of gallium and the yielded moles of gallium sulfide, therefore, we compute them as shown below:
Then, by using the molar mass of gallium sulfide (235.64 g/mol), we directly compute the grams:
Why do organisms evolve?Organisms make changes to help them survive and reproduce in their environment
Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Changes in the environment cause organisms to change. Organisms naturally select traits that help them survive and reproduce
In an ecosystem, organisms evolve to make changes to help them survive and reproduce in their environment.
What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
Consider the reaction at 25 °C. H2O(l) ↔ H2O(g) ΔG° = 8.6 kJ/mol Calculate the pressure of water at 25 °C (Hint: Get K eq)
H₂O(ℓ) ⟶ H₂O(g)
T = 25 °C
ΔG° = 8.6 kJ·mol⁻¹
T = (25 + 273.15) K = 298.15 K
Standard pressure is 1 bar.
In both industry and research there are often times when one particular component of a mixture needs to be separated from a solution. Maybe it is a rare metal that is dissolved in a mixture of minerals. Maybe it is a particular protein from lysed plant cells. If the desired component is volatile, distillation could be used. But if the goal is to separate ions in solution, fractional precipitation is preferred.a. True b. False
Distillation process is a process that is used to separate the components or the substances from the liquid mixtures by using selectively boiling and condensation.
While fractional precipitation is a process which separates the ions from solution based on the different solubilities.
Therefore, the answer is true.
