Answer:
Q = 31798.4J = 31.79kJ
Explanation:
Heat energy (Q) = ?
Mass (m) = 152g
T1 = 24°C
T2 = 74°C
Specific heat capacity of water (c) = 4.184J/g°C
Q = Mc∇T
Q = 152 * 4.184 * (74 - 24)
Q = 635.968 * 50
Q = 31798.4J
Q = 31.79kJ
Heat required is 31.79kJ
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions.
Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. ... is the heat added to, or removed from, the system.
B
atoms in a solid can move very little because of how compact they are
in a liquid atoms move a little more freely
in a gas atoms are bouncing fast as they are very spaced out
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.
