In which type of chemical reaction are electrons transferred

Physics
1 answer:
Naily [24]3 years ago
5 0

Answer:

Redox reactions

Explanation:

Redox (Reduction-Oxidation) reactions are reactions which involves the transfer of electrons. Here, one specie loses electrons while the other gains the electrons. The loss and gain of electrons makes one atom reduced while the other becomes oxidized. Transfer of electrons from one specie to another would eventually lead to a change in oxidation number of the reactants as they proceed to form products.

In non-redox reactions, there is no loss or gain of electrons and no change in oxidation number. An example is neutralization reaction.

sonic is sliding down a frictionless 15m tall hill. He starts at the top with a velocity of 10m/s. At the bottom of the hill he
podryga [215]

Answer:

The maximum speed of sonic at the bottom of the hill is equal to 19.85m/s and the spring constant of the spring is equal to (497.4xmass of sonic) N/m

Energy approach has been used to sole the problem.

The points of interest for the analysis of the problem are point 1 the top of the hill and point 2 the bottom of the hill just before hitting the spring

The maximum velocity of sonic is independent of the his mass or the geometry. It is only depends on the vertical distance involved

Explanation:

The step by step solution to the problem can be found in the attachment below. The principle of energy conservation has been applied to solve the problem. This means that if energy disappears in one form it will appear in another.

As in this problem, the potential and kinetic energy at the top of the hill were converted to only kinetic energy at the bottom of the hill. This kinetic energy too got converted into elastic potential energy .

x = compression of the spring = 0.89

A light wave travels through air at a speed of 3.0x108 m/s. Green light has a wavelength of about 5.76x1014Hz. What is the wavel
solong [7]

Answer:

521 nm

Explanation:

Given the values and units we are given, I'm assuming  5.76*10^14 Hz is frequency.

The formula to use here is λ * υ = c, where λ is wavelength, υ is frequency, and c is the speed of light.

λ = \frac{3*10^8\frac{m}{s} }{5.76*10^{14}Hz} = {5.20833*10^{-7} m}\approx{521 *10^{-9}m}={521 nm}

Boyles law<br> squeezing a balloon is one way to burst it. Why? ...?
KiRa [710]
According to Boyle's Law,  volume is inversely proportional to pressure. It means if the volume of a gas goes up the pressure goes down and if the volume of the gas goes up the pressure goes down. When the pressure of air inside the inflated balloon is more than the atmospheric pressure outside the balloon. And also when the density inside is greater than the density outside. The molecules inside the balloon move and bang around the inner walls which produces force, which provides the pressure of an enclosed air.

What is 8200 N/m2 expressed in kilopascals?
natima [27]
The S.I. unit for the measure of the pressure is the Pascal (Pa). 1 Pascal corresponds to
1 Pa = 1 N/m^2

We can convert the number given by the problem into Pascal:
8200 N/m^2 = 8200 Pa

And since 1 Pa = 10^{-3}kPa, we have
8200 Pa = 8200 \cdot 10^{-3}kPa =8.2 kPa
