How the moon surface is visible to an observer on earth

ehidna [41]

The moon surface is visible to an observer on earth due to the gravitational force that attracts the moon to the earth. The more massive the body is, the more the smaller body is attracted to the larger body. We can only see the side of the moon due to the speed at which the moon rotates.

Which of the following sources of pollution would be the most difficult to track and regulate? a. lawn fertilizer runoff b. a wa

VashaNatasha [74]

a. lawn fertilizer runoff

Pollution as a result of lawn fertilizer runoff would be difficult to track and regulate due to the possible breadth of the area affected. Toxins can be spread throughout the land area as well as be carried downstream if near a water source. Sewer systems, rivers, lakes, ponds, etc. can all be negatively affected by lawn fertilizer runoff. Irrigation or rain water can carry toxins for many miles before the effects are detected. Tracing the source of the toxins would be difficult, especially in a highly populated area.

How many moles of H2O are in 4.00 L of water?

scoray [572]

Answer:

0.179 mol H₂O

Explanation:

STP - 1 atm, 0°C

Assuming we're in STP:

Step 1: Find conversions

1 mol = 22.4 L at STP

Step 2: Use Dimensional Analysis

$4.00 \hspace{3} L \hspace{3} H_2O(\frac{1 \hspace{3} mol \hspace{3} H_2O}{22.4 \hspace{3} L \hspace{3} H_2O} )$ = 0.178571 mol H₂O

Step 3: Simplify

We have 3 sig figs.

0.178571 mol H₂O ≈ 0.179 mol H₂O
