Answer:

RbI

Explanation:

The formula of a compound can be obtained on the basis of number of anion and cations in the unit cell. Iodide is present at the eight corners of the cubic cell.

So, no. of iodide ion = 1/8×8= 1

rubidium is present at the center

so, no. of rubidium ion = 1×1 =1

Therefore formula of the compound = RbI

Answer:

The pH of the HCl solution is 3.9

Explanation:

Knowing the molar mass of HCl (36.5g/mol) it is possible to calculate the number of moles of HCl in the solution,

\frac{1.5x10^{-3}g}{36.5g/mol} = 4.1x10^{-5}moles of HCl

HCl is a strong acid and when added to water will form H+ and Cl-, thus the moles of HCl are equal to moles of H+ in 354 mL of water

\frac{4.1x10^{-5}moles }{354mL} x 1000= 1.16x10^{-4} M

The concentration of protons in the solutions is 1.16x10^{-4} M.

The expression used to calculate the pH is

pH = -Log ([H^{+}]) = -Log (1.16x10^{-4} M) = 3.9

Hence, the pH of the HCl solution is 3.9 and Pepsi has a pH of 3.4 approximately, so they have almost the same pH.
