i'd go for universal indicator, bromothymol blue and methyl red  

i mean, they have the degrees of acidity (specific color changes)  

they have wider ranges of color changes which will lead to the strength of acid  

you will know the degree of acidity of the cosmetics  

in fact, bromothymol blue is used to detect the slightest level of acid or base in a substance  

universal indicator has the pH charts; the range is big so that you can measure the level of acidity effectively  

methyl red is sensitive too as the other two mentioned earlier  

the other way that's not included in your choices is the pH meter  

unlike litmus papers which just have 2 results; either red or blue  

phenolphthalein only colorless, pale pink  

you won't know the degree of acidity  

hope that helps

Methane's chemical formula is CH. Is there a bond between any of the hydrogen atoms? Why or why not? (1 point)
irinina [24]

Answer:

No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.

Explanation:

from the shape of methane which is tetrahedral it's evident there's no hydrogen bond only C-H bond.

A and b are two gases that are mixed together: 2.50 mol a is mixed with 0.850 mol b. if the final pressure of the mixture is 1.7
USPshnik [31]

Partial pressure of gas A is 1.31 atm and that of gas B is 0.44 atm.

The partial pressure of a gas in a mixture can be calculated as

Pi = Xi x P

Where Pi is the partial pressure; Xi is mole fraction and P is the total pressure of the mixture.

Therefore we have Pa = Xa x P and Pb = Xb x P

Let us find Xa and Xb

Χa = mol a/ total moles = 2.50/(2.50+0.85) = 2.50/3.35 = 0.746

Xb = mol b/total moles = 0.85/(2.50+0.85) = 0.85/3.35 = 0.254

Total pressure P is given as 1.75 atm

Pa = Xa x P = 0.746 x 1.75 = 1.31atm

Partial pressure of gas A is 1.31 atm

Pb = Xb x P = 0.254 x 1.75 = 0.44atm

Partial pressure of gas B is 0.44 atm.
