Answer:
Explanation:
The instantaneous speed is the speed of an object at a particular moment in time. And if you include the direction with that speed, you get the instantaneous velocity.
<span>The answer would be: The two substances are not the same because the property that is independent of the amount of the sample is different.<span>
The two substances has different solubility which is </span></span>36 g/mL and <span>180 g/mL. The same kind of molecule should have same density and solubility, regardless the mass of the sample. In this case, the substances are not same since it has different solubility.</span>
Gosh, I love chem!
[H2O]/t should be 0.085M/s
this is because of the coefficients in front of H2S and H2O being the same.
the significance of this answer is that the H2S disappears at the same rate H2O appears.
The answer is C.
This can be concluded by looking at the other answers and eliminating them one-by-one.
Managing (Or conserving) a natural resource means to sustain it and use it as efficiently as possible.
With this in mind, we can look and eliminate certain answers.
A is incorrect because driving a car uses gas, a natural resource. By using as much gas as possible, the resource would be wasted instead of conserved.
B is incorrect because water is a natural resource. Once again, by using this, it's wasted where it could be conserved.
C is correct because planting trees would conserve the resource; by consistently planting trees where they're cut, the chances of running out of wood decrease.
D is incorrect because both the water and the creatures that live inside it are natural resources. By dumping toxic waste, these resources are wasted where it could be conserved.
Hope this helped you! :)
Answer:
the source of energy for food is sunlight energy and the inside the cells of plants, algae, and photosynthetic bacteria, chlorophyll, and enzymes use the light energy to rearrange the atoms of the reactants to form the products. molecules of the glucose and oxygen gas
