Zolol [24]

This is an incomplete question, here is a complete question.

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is approximately $2.15\times 10^6m/s$ ?

Find the force acting on the electron as it revolves in a circular orbit of radius $5.34\times 10^{-11}m$ .

Answer : The force acting on electron is, $7.9\times 10^{-8}N$

Explanation :

Formula used :

$F=\frac{mv^2}{r}$

where,

F = force acting on electrons

m = mass of electrons = $9.1\times 10^{-31}kg$

v = speed of electron = $2.15\times 10^6m/s$

r = radius of circular orbit = $5.34\times 10^{-11}m$

Now put all the given values in the above formula, we get:

$F=\frac{(9.1\times 10^{-31}kg)\times (2.15\times 10^6m/s)^2}{5.34\times 10^{-11}m}$

$F=7.9\times 10^{-8}N$

Thus, the force acting on electron is, $7.9\times 10^{-8}N$

During the cold winter months the surface Of a lake becomes hard Ice this is due to which change of state

nikitadnepr [17]

Freezing

Explanation:

This change in state when surface of a lake changes to hard ice is known as freezing.

When a solid is heated, it melts and changes to a liquid. On further heating, it changes to vapor and the randomness increases.
When a liquid is cooled below its freezing point, it changes to a solid such as ice for water.
The phase change is known as freezing.

Match each term with its correct description:

Artemon [7]

Answer:

Explanation:

Hydrocarbon:

a = An organic compound made up of only carbon and hydrogen.

Such as alkane, alkene, alkyne.

Cyclic hydrocarbon:

c = Carbon chain that form rings.

Such as benzene, cyclo heptane etc

Isomers:

d = Compounds with same molecular formula and different structural formula.

Alkanes:

e = refers to saturated hydrocarbons, no matter the shape

such as methane, ethane, propane etc.

Alkene:

f = Any hydrocarbon that have at lest one carbon carbon double bond.

such as ethene, propene, butene

Saturated hydrocarbons:

b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed

such alkanes.

jeka57 [31]

Hydrocarbons are a type of organic compound. Hydrocarbons contain a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates, and nitrous oxides are not organic compounds but they are inorganic compounds.
