eduard

Answer:

D

Explanation:

The noble gases are said to be inert because they undergo very few chemical reactions. They enjoy their status by having completely filled electron shells and do not have any reason whatsoever to go into chemical reactions. Most elements otherwise go into chemical reactions principally to enjoy the stability of these elements.

Noble gases can be found in the last group of the periodic table.

gamma rays have an approximate wavelength of 1.0x10^-13 meters. what is the approximate energy of a gamma-ray?
Bogdan [553]

Answer:

E = 19.89 × 10⁻¹³ J

Explanation:

Given data:

Wavelength of gamma ray= 1.0× 10⁻¹³ m

Energy of gamma ray = ?

Solution:

Formula:

E = h c/λ

h = plancks constant  = 6.63× 10⁻³⁴ js

c = speed of light = 3 ×10⁸ m/s

by putting values,

E = 6.63× 10⁻³⁴ js × 3 ×10⁸ m/s /1.0× 10⁻¹³ m

E = 19.89 × 10⁻²⁶ J.m/ 1.0× 10⁻¹³ m

E = 19.89 × 10⁻¹³ J

PLEASE HELP!! I'LL MARK U BRAINIEST!! ALSO PLZ IF YOU CAN SHOW THE WORK
mel-nik [20]

Answer:

9.63×10²⁴ particles of H₂O

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

From the balanced equation above,

1 mole of CH₄ reacted to produce 2 moles of H₂O.

Next, we shall determine the number of mole of H₂O produced by the reaction of 8 moles of CH₄. This can be obtained as follow:

From the balanced equation above,

1 mole of CH₄ reacted to produce 2 moles of H₂O.

Therefore, 8 moles of CH₄ will react to produce = 8 × 2 = 16 moles of H₂O.

Thus, 16 moles of H₂O were obtained from the reaction.

Finally, we shall determine the number of particles of H₂O produced. This can be obtained as follow:

Number of mole of H₂O produced = 16 moles

Number of particles produced =?

From Avogadro's hypothesis,

1 mole = 6.02×10²³ particles

Therefore,

16 mole = 16 mole × 6.02×10²³ particles / 1 mole

16 moles = 9.63×10²⁴ particles

Therefore, 9.63×10²⁴ particles of H₂O were produced.
