A 250ml sample of 0.20M HCl is to be made by diluting the approximate amount of the concentrated reagent 11.7M what volume of the latter should be used?

250 x 0.2 = V x 11.7
Therefore V = 250 x 0.2 /11.7 = 4.27 say 4.3 ml
so take 4.3 ml of 11.7 M acid and dilute to 250 ml in a volumetric flask, you will get 250 ml of 0.2M HCl.

What is the temperature at which air can no longer hold all the water vapor?
That's an approximate definition of saturation. And the temperature at which the current amount of water vapor in the air would be the saturation point is called the dew point. The dew point is a measure of absolute humidity.
How much water would you need to add to 500ml of a 2.4m kcl solution to make a 1.0 m solution?
A 3 Molar solution has 3 moles of reagent per liter. 500mL of that solution has 1.5 moles of reagent. So to create a 2 moles per liter solution with 1.5 M or reagent, you will need a volume of 750 mL. So you will need to add 250 mL of water.
How does the way sunlight hits earth affect the way different parts of the earth are heated?
The angel of the sunlight determine how much they heat up the earth. The axel of the earth is tilted 23.5 degrees in relation ship to the sun. This is what gives us the different seasons. When the angel is wide a specific amount of sunlight will be spread out over a big area and each part is only heated up a little. When the angel is narrow the same amount of sunlight is concentrated on a smaller area and that area is heated up much more.
How would you prepare 1600 ml of a pH 1.50 solution using concentrated 12M HCl?
Start with the pH. pH is -log(H)=1.5 Solve for H (this is your concentration of hydrogen). This comes out to be .0316=[H]. This means there are .0316 mols of H in 1 liter of solvent. So now that we know this, we can use this equation MoVo=MfVf (o is initial, f is final, M is molar, V is volume) So plug in the numbers (.0316)(1.6)=(12)(Vf) Vf = .001813 L or 1.813 mL. So you'd take 1.813 mL of 12 M HCl and dilute it to 1600 mL This makes sense because 12M HCl has a very LOW pH, so diluting with such amount of solvent is necessary. Now that I have more time, I'll tell you how you want to approach this. The thing is all about the equation MoVo=MfVf. This equation is used for diluting. Now we have two of these values, we just need the other M to solve for volume of 12 M HCl. So how does pH relate to this problem (namely concentration)? We pH is a measure of concentration. That is -log[H]. So We must solve for [H]. Upon doing so, we then consider this: What happens when HCl dissociates? Well here it is HCl ====> H + Cl So for every mol of HCl, we get a mol of H. Therefore, [HCl]=[H] So there you have it!!
What is the best substance to neutralise sodium hydroxide solution?
Any acid can be used to neutralize a base such as sodium hydroxide. If you have a concentrated solution of sodium hydroxide, you could neutralize it most efficiently with a strong acid such as hydrochloric acid. You can also neutralize it with Coca Cola, or vinegar, or many other acidic chemicals, but it would require a larger amount than if you used hydrochloric acid.
The difference between concentrated detergent and regular detergent?
The only difference is the amount of water and other fillers diluting the detergent.
If you want to read the absorbance at 595nm of a protein solution mixed with the colorizing solution called Bradford reagent what is a suitable reagent blank?
a "blank" cuvette can be made with a sufficient amount of distilled water (assuming you're diluting your stock solution with distilled water).
