Can Iron replace Hydrogen in the following reaction?: Fe(s) + HCl(aq) ---&gt; H2(g) + FeCl2(aq)
Elenna [48]
It can because Iron is more reactive than Hydrogen and a more reactive metal always replaces a less reactive one in a single replacement reaction

What is the volume of 1.56 kg of a compound whose molar mass is 81.86 g/mole and whose density is 41.2 g/ml?
hjlf

Answer:

v = 37.9 ml

Explanation:

Given data:

Mass of compound = 1.56 kg

Density = 41.2 g/ml

Volume of compound = ?

Solution:

First of all we will convert the mass into g.

1.56 ×1000 = 1560 g

Formula:

D=m/v

D= density

m=mass

V=volume

v = m/d

v =  1560 g / 41.2 g/ml

v = 37.9 ml

A sample of lemon juice is found to have a pH of 2.3. What is the concentration of hydrogen ions in the lemon juice?
Elenna [48]

Answer: It's equal to 10^(-2.3), or 0.00501 M, or 5.01 * 10^-3 moles/Liter

Explanation:

Well, pH = - log[H+]

Or, in words, pH is equal to -1 multiplied by the logarithm (base 10) of the hydrogen ion concentration.   So you have 2.3 = -log[H+].    We want to isolate the H+, so let's start simplifying the right hand side of the equation. First, we multiply both sides by -1.   -2.3=log[H+]   Now, the definition of a logarithm says that if the log (base 10) of [H+] is -2.3, then 10 raised to the -2.3 power is [H+]   So on each side of the equation, we raise 10 to the power of that side of the equation.   10^(-2.3) = 10^(log[H+])   and because 10^log cancels out...   10^(-2.3) = [H+]   Now we've solved for [H+], the hydrogen ion concentration!
