Which planet likely has flowing liquid metallic hydrogen as the source of its magnetic field?

ch4aika [34]

Answer:

A precipitation is said to be complete precipitation when no further precipitate can be formed in the process.

Explanation:

Precipitation is the reaction of creating solid from the solution. In precipitation reactions, insoluble salts are formed when two solutions containing soluble salts are combined.

These two solutions contain different salts and have either cation or anion pairing. This reaction helps in the determination of ions in a solution. The solubility table is being used to predict the precipitation reaction. It occurs in solid when one solid’s concentration is above solubility.

Lady_Fox [76]

Answer:

The speed of the wave in the rope is 2 m/s

Explanation:

1. Data:

a) ν = 4 Hz

b) λ = 0.5 m

c) s = ?

2. Physical principles and formula:

The propagation of waves in a rope is a classical example of transverse waves: the pulse is inflected in the vertical direction and the wave travels in the horizontal direction, i.e. the pulse or vibration is perpendicular to the motion of the media particles.

The equation that relates speed (s), wavelength (λ), frequency (ν) is:

distance = speed × time

wavelength = speed × period

wavelenfth = speed / frequency

λ = s / ν

meter = (meter/second) / second⁻¹

m = (m /s) / s⁻¹

3. Solution:

λ = s / ν⇒ s = λ·ν

s = 0.5 m × 4 Hz = 2 m/s

Answer:

K = 0.0003 s⁻¹

Explanation:

The reaction is

2N₂O₅ = 4NO₂ + O₂

The equilibrium is

$K[N_{2} O_{5} ]=-\frac{1}{2} \frac{d[N_{2} O_{5} ]}{dt} \\\int\limits^y_x {d[N_{2} O_{5} ]}{} \, =-2k\int\limits^t_0 {dt} \,\\ln[N_{2} O_{5} ]=-2kt+ln[N_{2} O_{5} ]$
