What do the coefficients of a balanced equation represent

Chemistry
1 answer:
Natali5045456 [20]4 years ago
7 0

Answer:

Coefficients of a balanced equation represent the amount of moles, that has each reactant and the products that are made

Explanation:

In the reaction:

2H₂ (g) + O₂ (g)  → 2H₂O (g)

2 moles of hydrogen react with 1 mol of oxygen to produce 2 moles of water.

If there is no coefficient, you assume a value of 1.

You can also say, 1 mol of oxygen reacts with 2 moles of hydrogen to produce 2 moles of water.

mash [69]

Yes, it will be worthwhile to investigate finding a catalyst to use in this reaction under standard conditions because it is negative.

<h3>What is a Catalyst?</h3>

This is a substance which speeds up the rate of a chemical reaction by lowering the activation energy.

ΔG being negative indicates a a slow reaction which is why a catalyst under standard conditions should be used.

X-rays had a frequency of about 3x10^18 determine it's wavelength (in nm) and energy per photon
Serggg [28]

Answer:

E = 19.89×10⁻¹⁶ J

λ = 1×10⁻¹ nm

Explanation:

Given data:

Frequency of xray = 3×10¹⁸ Hz

Wavelength of xray = ?

Energy of xray = ?

Solution:

speed of wave = wavelength × frequency

speed = 3×10⁸ m/s

3×10⁸ m/s  = λ ×3×10¹⁸ s⁻¹

λ = 3×10⁸ m/s  / 3×10¹⁸ s⁻¹

λ = 1×10⁻¹⁰m

m to nm:

λ = 1×10⁻¹⁰m×10⁹

λ = 1×10⁻¹ nm

Energy of x-ray:

E = h.f

h = plancks constant = 6.63×10⁻³⁴ Js

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10¹⁸ s⁻ ¹

E = 19.89×10⁻¹⁶ J
