Answer:
This question is asking to find the average speed during the dive. The answer is 22m/s.
Explanation:
Average speed of a substance can be calculated knowing it's distance over a particular amount of time.
The formula for average speed is:
Average speed (s) = Distance (d) / time (t)
In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;
Average speed = 176/8
Average speed = 22
Therefore, the average speed of the falcon diver is 22m/s.
Answer:
1.566x10²⁴ atoms of Cl
Explanation:
In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:
<em>Moles CCl₄: 153.82g/mol</em>
100g * (1mol / 153.82g) = 0.65 moles CCl₄
<em>Moles Cl:</em>
0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl
<em>Atoms Cl:</em>
2.6 moles Cl * (6.022x10²³ atoms / mol) =
<h3>1.566x10²⁴ atoms of Cl</h3>
Answer:
Mass movement, or mass wasting, has significant effects on humans, including loss of property, severe injury and death.
Explanation:
5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
Homogeneous mixture that does not settle out upon standing but which will reflect light is called COLLOIDS.
There are three types of homogeneous mixtures, these are: solutions, colloids and suspension. Colloids are usually distinguished by Tyndall effects. Light passing through a colloidal dispersion will be reflected.<span />
