Answer:
By using any one technique like boiling, distillation, condensation ,etc , one can be used to distinguish between a pure substance and a homogeneous mixture.
Explanation:
If the liquid is a pure substance, then it can not be separated by using physical means because all atoms of a pure substance show same properties.
But on the other hand, if there is homogeneous mixture, it can be separated by using techniques like boiling, distillation, condensation ,etc.
<u>Thus, using any of the one method listed above can be used to distinguish between a pure substance and a homogeneous mixture.</u>
Answer:
10 km/hr
Explanation:
We are told that a jogger runs;
3km in 0.3 hr and
7 km in 0.7 hr
We are required to determine the average speed;
We need to know that average speed is given by;
Average speed = Total distance ÷ total time
In this case;
Total distance = 10 km ( 3km + 7 km)
Total time = 0.3 hr + 0.7 hr
= 1 hr
Thus;
Average speed = 10 km ÷ 1 hr
= 10 km/hr
Therefore, the average speed of the jogger is 10 km/hr
Mass of reactants= mass of products
The plant will grow less than 5 centimeters because it is a seedless, non-vascular plant. The correct option is B.
<h3>What are moss plants?</h3>
Moss plants are those plants that do contain seeds or flowering plants. They are non-vascular plants, and they maintain the moisture of the soils. They are very small plants.
Moss plants are small plants that grow in moist and humid conditions. They do not need so much sunlight. They will grow less than 5 centimeters and wet conditions.
Thus, the correct option is B. less than 5 centimeters because it is a non-vascular plant.
