The question is incomplete. Nonetheless, I gave an example of atmospheric stewardship. First, it’s important to understand that stewardship implies a duty for humans to care for and preserve our environment, which includes the atmosphere. One way to demonstrate this is by changing how we travel; for example, opting to bike instead of using a car. This choice would help decrease greenhouse gas emissions since bicycles do not release harmful gases.
A system is considered at equilibrium when the concentrations of reactants and products stay constant over time. Reactions that do not reach completion, where reactants can form products while products can revert back to reactants simultaneously, are categorized as equilibrium reactions. The nature of equilibrium is dynamic, meaning reactions continue to occur, with the rate of the forward reaction equating to that of the reverse reaction. In this state, even though both reactants and products coexist, their concentrations do not vary.
3,048 minutes. Explanation: 762 divided by 5, then multiply that number by 20.
Response:
a. To purify a gypsum sample, you will need the following equipment: Bunsen burner, beaker, filter funnel, stirring rod, and filter paper.
b. Gypsum, a sulfate mineral consisting of calcium sulfate dihydrate, can be purified by following these steps:
1. Add water to the gypsum in a beaker.
2. Stir the mixture thoroughly with the stirring rod.
3. Use the filter paper and filter funnel to remove excess solids from the mixture.
4. Heat the filtered mixture on the Bunsen burner to evaporate the remaining water.
5. After cooling, filter again through the filter paper to obtain pure gypsum.
Answer:
0.5 g/mL----- will float
1.0 g/mL---- will float
2.0 g/mL----- will sink
Explanation:
Objects with a density less than or equal to that of water will float due to having a lower mass, while objects with a density exceeding that of water will sink because their mass is greater than that of water. Thus, objects with a density of 0.5 g/mL and 1.0 g/mL will float since they are less dense than water (1 g/mL), whereas an object with a density of 2.0 g/mL will sink.
