Chemistry
1 answer:
padilas [110]3 years ago
7 0

Answer:

The frequency  

Step-by-step explanation:

The formula for the energy of an electromagnetic wave is  

E = hf     Thus,  

E ∝ f       and

f ∝ E

Homogeneous mixture that does not settle out upon standing reflect light is an element. solid. hydrated.
andrey2020 [161]
Homogeneous mixture that does not settle out upon standing but which will reflect light is called COLLOIDS.
There are three types of homogeneous mixtures, these are: solutions, colloids and suspension. Colloids are usually distinguished by Tyndall effects. Light passing through a colloidal dispersion will be reflected.<span />

Consider the following reaction at equilibrium: 2 NH3(g) ⇄ N2(g) + 3 H2(g) What does Le Chatelier's principle predict will happe
BabaBlast [244]

Answer : The equilibrium will shift in the left direction.

Explanation :

Le-Chatelier's principle : This principle states that if any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

The given reaction is:

2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)

As per question, when we are adding N_2  then the concentration of N_2 is increased on product side then the equilibrium will shift in the direction where decrease of concentration of N_2 takes place. Therefore, the equilibrium will shift in the left direction.

Thus, the equilibrium will shift in the left direction.

Which of the following are held together by nonpolar convalent bonds?
Olin [163]

A. Atoms of chlorine (Cl)

Explanation:

The atoms of chlorine are held together by non-polar covalent bonds.

  • Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
  • For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
  • This covalent bond type is called non-polar covalent bond.
  • In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.

How many grams of diphosphorus pentoxide result if 100.0 g of phosphorus are combined with sufficient oxygen?
gregori [183]
Answer is: 230 g.
Chemical reaction: P₄ + 5O₂ → 2P₂O₅.
m(P₄) = 100 g.
M(P₄) = 4 · 31 g/mol = 124 g/mol.
n(P₄) = m(P₄) ÷ M(P₄) = 100g ÷ 124g/mol = 0,806 mol.
From reaction: n(P₄) : n(P₂O5) = 1 : 2.
n(P₂O₅) = 1,612 mol.
m(P₂O₅) = 1,612 mol · 142g/mol = 230g.
M - molar mass.
n - amount of substance.
