For an atom to achieve a stable electron configuration, it needs 8 valence electrons. Since this atom has 6 valence electrons, it needs 2 more to achieve a stable electron configuration.
8-6=2
Answer:
The spacing between the planes of the crystal is 0.295 nm
Explanation:
Given:
λ = wavelength = 0.24 nm
θ = angle of incidence = 66°
The spacing d between the planes of the crystal is equal:
Answer:
lens my guess is iris
Explanation:
The Lens. The lens is composed of transparent, flexible tissue and is located directly behind the iris and the pupil. It is the second part of your eye, after the cornea, that helps to focus light and images on your retina.
<h3>
Answer: C) Weight</h3>
Explanation:
The car still retains its mass because the matter is still there. The particles that make up the car are still present. The car also has inertia since inertia is effectively a measure of mass. We can rule out choices A and B because of these reasons.
The car wouldn't have weight in space because the pull of gravity isn't as strong. The pull of gravity is still there, but it's much more miniscule which produces the weightlessness of the object. Recall that the force of gravity reduces as the distance between the objects increases.
The pressure inside the container will be <u>9.39×10⁴Pa</u>
At constant volume, the pressure in a container is directly proportional to its absolute temperature.
If air in a container is sealed at 20⁰C at a pressure equal to the atmospheric pressure and cooled to 2.00⁰C, the pressure inside the container falls.
Convert the temperature in Celsius to Kelvin.
Use the expression for the pressure law.
Substitute 100,000 Pa for P₁, 293.16 K for T₁ and 275.15K for T₂.
The pressure in the container (correct to 2 sf) is <u>9.39×10⁴Pa</u>
