Why don't siblings look exactly alike

Chemistry
1 answer:
marusya05 [52]3 years ago
3 0

Answer:

Your genes play a big role in making you who you are. ... But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.

When dissolved in water, hydrogen bromide (hbr) forms hydrobromic acid. determine the hydroxide ion concentration in a 4,500 ml
vovikov84 [41]

No of moles of HBr = 3.78g / 80.9 = 0.0467moles 
 Molarity = Number of moles/ volume. So we have 0.0467 / 4.5 = 0.0103M. 
 Kw = 1.0 x 10 -14 = [H3O+] [OH-] and [OH-] = 1.0 x 10^(-14) / [H3O+] 
 So [OH-] = 1.0 * 10^(-14) /1.03 *10^(-2) = 0.9703 * 10^(-12) M

5. A 180 mL disinfectant solution contains 85 mL of isopropyl alcohol. Determine the V/V
lyudmila [28]

The % V/V concentration of a 180-mL disinfectant solution containing 85 mL of isopropyl alcohol is 47 % V/V.

<h3>What is the % V/V concentration?</h3>

It refers to the milliliters of solute for every 100 milliliters of solution.

We have 180 mL of a disinfectant solution that contains 85 mL of isopropyl alcohol (solute).

The % V/V concentration of this solution is:

% V/V = (mL solute/mL solution) × 100% =

% V/V = (85 mL/180 mL) × 100% = 47% V/V
