Which type of electromagnetic wave has the most energy?

Chemistry
2 answers:
rewona [7]3 years ago

Answer: Gamma rays

Explanation:

Gamma rays have the most energies and shortest wavelengths on the electromagnetic spectrum. They are derived from free negatrons and stripped microscopic nuclei stimulated by powerful magnetic fields in exploding stars, colliding neutron stars, and supermassive black holes. Radio waves are the opposite. Radio waves have the lowest energies, longest wavelengths, and lowest frequencies of any EM radiation.

When the released energy reaches the outer layers of the ball of gas and dust, it moves off into space in the form of electromagnetic radiation. The ball, now a star, begins to shine.

If 18.7ml of 0.01500M aqueous HCl is required to titrâtes 15.00ml of an aqueous solution of NaOH to the equivalence point, what
sweet [91]

Answer:

0.0187 M

Explanation:

Step 1: Write the balanced neutralization reaction

NaOH + HCl ⇒ NaCl + H₂O

Step 2: Calculate the reacting moles of HCl

18.7 mL of 0.01500 M HCl react.

0.0187 L × 0.01500 mol/L = 2.81 × 10⁻⁴ mol

Step 3: Calculate the reacting moles of NaOH

The molar ratio of HCl to NaOH is 1:1. The reacting moles of NaOH are 1/1 × 2.81 × 10⁻⁴ mol = 2.81 × 10⁻⁴ mol.

Step 4: Calculate the molarity of NaOH

2.81 × 10⁻⁴ moles are in 15.00 mL of NaOH.

[NaOH] = 2.81 × 10⁻⁴ mol/0.01500 L = 0.0187 M

Hydrogen is used as a rocket fuel because it is very light and reacts explosively and completely with oxygen. For the combustion
777dan777 [17]

Answer:

1. K<10−3

Explanation:

Equilibrium Constant is an expression which involves the concentration of the product divided by the concentration of the reactant molecules.

However the concentration of the pure liquid and pure solid is regarded as 1.

Equilibrium expression for the equation 2H2(g)+O2(g)⇌2H2O(g)

Equilibrium Constant = [H2O]^2/[H2]^2 x [O2]

Since H2O is a pure liquid, its concentration = 1

There fore;

Equilibrium Constant = 1/[H2]^2 x [O2]

This shows that the Equilibrium Constant of the equation will be less than 1 and greater than 0.

"calculate the h+ in a solution that has a ph of 8.73"
alexdok [17]
The  H+   in  a  solution  that  has  a Ph  of  8.73   is   calculate    as  follows

Ph is always =   -  log  (H+)

H+  =    10^-Ph

H+  is  therefore  =  10 ^-  8.73
H+  =  1.86  x10^-9  M
