Answer:
=1.36kg
Explanation:
First heat is absorbed to melt the ice- latent heat of fusion of ice then heat is absorbed to raise the temperature to 373K
The specific heat capacity of water is 4.187kJ/kg/K while the latent heat of fusion of ice is 2230kJ/kg/K.
Letting the mass of the ice to be =x
x×2230kJ/kg/K + x×4.187kJ/kg/K×100K= 3600kJ
2230x+418.7x=3600
2647.8x=3600
x=1.36 kg
Answer:
chemical bonds
Explanation:
The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces.
Answer:
1,3- dichlorobutane
Explanation:
The IUPAC name of given compound is 1,3- dichlorobutane.
First of all we will select the longest chain.
The given compound is straight chain. So the compound have four carbon atoms means parent name will butane.
Then we will see the position of functional group. Gives the lowest possible number to the functional group attached.
In given compound one chlorine atom is attached on left side and other is on right side. we will start the numbering from left because in this way chlorine will get lowest possible number which 1 and 3.
As we start the numbering from left the one chlorine atom get number one and other is attached on carbon 3 will have number 3.
There are two chlorine atoms so we will give name "dichloro"
The name will be,
⁴CH₃-³CHCl-²CH₂-¹CH₂Cl
1,3- dichlorobutane.
Answer:
Colloids (heterogeneous)
The difference between a colloid and a suspension is that the particles will not settle to the bottom over a period of time, they will stay suspended or float. An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water.
Well if it were to freeze , the molecules move and become a solid slowly
