The average distance between nitrogen and oxygen atoms is 115 pm in a compound called nitric oxide. What is this distance in mil
lorasvet [2795]

Answer:

C) 1.15 × 10⁻⁷ mm

Explanation:

Step 1: Provided information

Average separation between oxygen and nitrogen atoms: 115 pm

Step 2: Change the distance to meters (SI standard unit)

Using the conversion 1 m = 10¹² pm.

115 pm × (1 m/10¹² pm) = 1.15 × 10⁻¹⁰ m

Step 3: Transform the distance to millimeters

Employing the conversion 1 m = 10³ mm.

1.15 × 10⁻¹⁰ m × (10³ mm/1 m) = 1.15 × 10⁻⁷ mm

If the kinetic energy of a particle is equal to twice its rest mass, what is the velocity of the particle? Determine if relativi
lorasvet [2795]

Answer:

The particle's velocity is calculated to be 2 m/s,

Explanation:

Kinetic energy refers to the energy an object possesses due to its movement. The formula for kinetic energy is:

K.E=\frac{1}{2}mv^2

Where:

m = the mass of the object

v = the object's velocity

A particle with mass m has a kinetic energy that is double its mass.

K.E=2m

2m=\frac{1}{2}mv^2

v^2=\frac{4}{1}

v=2

Since the velocity is measured in m/s, we determine that the particle's speed is 2 m/s.

castortr0y [3046]
At equilibrium, [R] = [Z] > [Q]. Explanation: In analyzing the equilibrium conditions, the provided reaction of X(g) + 2 Q(g) ⇄ R(g) + Z(g) establishes that at a temperature of 50ºC, the equilibrium constant Kc = 1.3 x 105. This indicates a scenario where the concentrations of the products greatly exceed those of the reactants.
