Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules

A 9.79 mol sample of freon gas was placed in a balloon. Adding 3.50 mol of freon gas to the balloon increased its volume to 21.8
aivan3 [116]

Answer:

16.06 L was the initial volume of the balloon.

Explanation:

Initial moles of freon in ballon = n_1=9.79 mol

Initial volume of freon gas in ballon = V_1=?

Moles of freon gas added in the balloon = n = 3.50 mole

Final moles of freon in ballon = n_2=n_1+n=9.79 mol+3.50 mol=13.29 mol

Final volume of freon gas in ballon = V_2=21.8 L

Using Avogadro's law:

\frac{V_1}{n_1}=\frac{V_2}{n_2} ( at constant pressure and temperature)

V_1=\frac{V_2\times n_1}{n_2}=\frac{21.8 L\times 9.79 mol}{13.29 mol}=16.06L

16.06 L was the initial volume of the balloon.

Carboplatin (C6H12N2O4Pt) is a platinum-containing compound that is used to treat certain forms of cancer. This compound contain
givi [52]

Answer:

The answer to your question is:  $ 35.6

Explanation:

C₆H₁₂N₂O₄Pt

Platinum = 52.5 %

Price = $1047 / troy ounce

cost of platinum = ? of 2 g

1 troy ounce = 480 grains

1 grain = 64.8 mg

Process

Get 52.5 % of 2 g

                               2 g -----------------  100 %

                               x     -----------------  52.5%

                              x = (52.5 x 2) / 100

                              x = 1.05 g

                               1 g --------------------- 1000 mg

                               1.05 g ----------------   x

                               x = 1050 mg of Pt

                               1 grain ---------------- 64.8 mg

                              x            ---------------  1050 mg

                              x = 16.2 grains

                              480 grains ---------------- 1 troy ounce

                              16.2 grains ----------------   x

                               x = (16.2 x 1) / 480

                                x = 0.034 troy ounce

                              $ 1047 ------------------  1 troy ounce

                                x        -------------------  0.034

                                x = (0,034 x 1047) / 1

                                x = $ 35.6

To what volume would you need to dilute 200 mL of a 5.85M solution of Ca(OH)2 to make it a 1.95M solution?
Blizzard [7]

Answer: 600 mL

Explanation:

Given that;

M₁ = 5.85 m

M₂ = 1.95 m

V₁ = 200 mL

V₂ = ?

Now from the dilution law;

M₁V₁ = M₂V₂

so we substitute

5.85 × 200 = 1.95 × V₂

1170 = 1.95V₂

V₂ = 1170 / 1.95

V₂ = 600 mL

Therefore final volume is 600 mL
