hi:) evaporation is the process by which liquids changes to gas at temperatures lower than boiling point. But why can’t liquids

evaporate at their boiling point? Is that because liquids will boil instead of evaporate? Anyone able to help I’m rlly confused.

Answer:

evaporation is the process by which liquids changes to gas at temperatures lower than boiling point. But why can’t liquids evaporate at their boiling point? Is that because liquids will boil instead of evaporate?

Evaporation only take place at a certain temperature or it is high at a particular temperature which makes it to be rapid then, when liquid is heated, at a temperature the vapor leaves and evaporates in gaseous form known as vapor to the atmosphere. Evaporation takes place below the temperature of boiling point and above it but the rapidity depends on the temperature, the higher the temperature the rapid the evaporation takes place

Answer: I’m not sure if this will help, but once it reaches its boiling point and actually makes the state of matter change from a liquid to gas, that is referred to as vaporization. Evaporation occurs below the boiling point and vaporization occurs at or above it.

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to
murzikaleks [220]

Answer:

Force used by fire extinguisher = 60 N

Explanation:

Given:

Mass of skateboard with fire extinguisher = 50 kg

Acceleration of fire extinguisher = 1.2 m/s²

Find:

Force used by fire extinguisher = ?

Computation:

⇒ Force = Mass × Acceleration

⇒ Force used by fire extinguisher = Mass of skateboard with fire extinguisher × Acceleration of fire extinguisher

⇒ Force used by fire extinguisher = 50 kg × 1.2 m/s²

⇒ Force used by fire extinguisher = 60 N

What are the first two quantum numbers for the electrons located in subshell 4d?
SCORPION-xisa [38]

Answer:

n = 4, l = 2

Explanation:

The number 4 in 4d is the principal quantum number (n).

The letter d in 4d tells us that we have a d orbital, as determined by the <em>secondary quantum number (l</em>).

The quantum number l tells us the shape of the orbital.

l = 0     s orbital

l = 1      p orbital

l = 2     d orbital

Carbon has four valence electrons. true false
8090 [49]
The answer is true. One neutral atom of carbon has four valence electrons.
 
An easy way of finding out is to check out the periodic table and look at which main number group the element is in. Carbon is in group number four, which would mean it has four valence electrons.

Hope I was able to help!

g Alkenes and alkynes are called unsaturated compounds because ________. they have fewer hydrogen atoms attached to the carbon c
Firdavs [7]

Answer:

They have fewer hydrogen atoms attached to the carbon chain than alkanes

Explanation:

Let's compare ethane (an alkane) with ethene (an alkene) and ethyne (an alkyne):

  • Ethane's formula is C₂H₄, while ethene's is C₂H₄ and ethyne's C₂H₂.

As you can see, alkenes and alkynes have fewer hydrogen atoms attached to the carbon chain due to them having multiple bonds between the carbon atoms.
