Calculate the wavelength of light with an energy of 3.60x10^-19 J *

Chemistry
1 answer:
Travka [436]3 years ago
3 0

Explanation:

from E = mc^2 and de Broglie wavelength=h/mc

combine the eqns with respect to m(considering the body is moving with the speed of light(c))

then

E= hc/de Broglie wavelength

since, c= 3× 10^ 8

h= 6.626 × 10^ -34 and E is given, substitute the values.

sorry I don't have my calculator.

Predict the products for the following equation.
coldgirl [10]

Answer: AgCl + Fe

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

XY+Z\rightarrow XZ+Y

The blanced chemical reaction will be :

3Ag+FeCl_3\rightarrow 3AgCl+Fe

In a titration of 0.5 M HCl and an unknown concentration NaOH, 25.0 ml of NaOH was required to completely neutralize 25.0 ml of
baherus [9]
When an acid is neutralized by a base, that means moles of H+ = moles of OH-

moles of H+ = 0.5 M * 0.025 L HCl = 0.0125 moles H+

moles of OH- should be equal to 0.0125 moles, so
0.0125 moles = (x) * 0.025 L NaOH

x is the concentration of NaOH, which we want to find.

x = 0.5 M

The correct answer is C) 0.5 M.

Concentrated HCl is 15 M (15 molar). A 500 mL quantity of this solution is diluted by adding water to give a final volume of 2.5
Murrr4er [49]

The molarity of the resulting solution obtained by diluting the stock solution is 3 M

<h3>Data obtained from the question </h3>
  • Molarity of stock solution (M₁) = 15 M
  • Volume of stock solution (V₁) = 500 mL
  • Volume of diluted solution (V₂) = 2.5 L = 2.5 × 1000 = 2500 mL
  • Molarity of diluted solution (M₂) =?

<h3>How to determine the molarity of diluted solution </h3>

M₁V₁ = M₂V₂

15 × 500 = M₂ × 2500

7500 = M₂ × 2500

Divide both side by 2500

M₂ = 7500 / 2500

M₂ = 3 M

Thus, the volume of the resulting solution is 3 M
