To what volume in millimeters must 50.0 mL of 18.0 M H2SO4 be diluted to obtain 4.35 M H2SO4?
poizon [28]
We know that to relate solutions of with the factors of molarity and volume, we can use the equation: M_{1}  V_{1} = M_{2}  V_{2}

**NOTE: The volume as indicated in this question is defined in L, not mL, so that conversion must be made. However it is 1000 mL = 1 L.

So now we can assign values to these variables. Let us say that the 18 M H_{2}  SO_{4} is the left side of the equation. Then we have:

(18 M)(0.050 L)=(4.35M) V_{2}

We can then solve for V_{2}:

V_{2}= \frac{(18M)(0.05L)}{4.35M} and V_{2} =0.21 L or 210 mL

We now know that the total amount of volume of the 4.35 M solution will be 210 mL. This is assuming that the entirety of the 50 mL of 18 M is used and the rest (160 mL) of water is then added.

Every afternoon, Bill and Anita go down to the beach to fly their kite. They noticed that the wind always blows towards shore. W
EastWind [94]

Answer:

the answer is D

Explanation:

Air over the beach heats up, rises, and is replaced by cool, denser ocean air

The ocean heats up much slower and becomes relatively cooler than the beach making it a high pressure zone. The air moves from the water to the land each morning forming a sea breeze. These pressure zones might equal out later in the day and the winds may diminish. ... A sea breeze blows from the ocean towards the beach.

How does chemical weathering change rock​
tekilochka [14]

Answer:

Not to be rude but its in there. Hope this helps

Explanation:

Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.
