Answer:

E = 9.95×10⁻¹⁹ J

Explanation:

Given data:

Wavelength = 2×10⁻⁷ m

Energy of photon = ?

Solution:

Formula:

E = hc/λ

h = 6.63×10⁻³⁴ Js

c = 3×10⁸ m/s

by putting values,

E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 2×10⁻⁷ m

E = 19.89×10⁻²⁶Jm / 2×10⁻⁷ m

E = 9.95×10⁻¹⁹ J

Answer:

Explanation:

Explanation:

The reaction expression is given as:

Al(OH)₃ + HNO₃ → H₂O + Al(NO₃)₃

To solve this problem, let us assign coefficient a,b,c and d to each specie;

aAl(OH)₃ + bHNO₃ → cH₂O + dAl(NO₃)₃

Conserving Al : a = d

O: 3a + 3b = c + 9d

H: 3a + b = 2c

N: b = 3d

let a = 1 , d = 1, b = 3 , c = 3

Multiply through by 3;

a = 1, b = 3, c = 3 and d = 1

Al(OH)₃ + 3HNO₃ → 3H₂O + Al(NO₃)₃

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.
