The wood turns into ash and smoke so mass is nor destroyed or created.
Answer:
30.33L
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant and Charles law states that the volume of a given mass of gas is directly proportional to the temperature provided the pressure remains constant
P1V1/T1 = P2V2/ T2
P1 = 78atm, V1 = 21L , T1 = 900K
P2 = 45atm, V2 = ? , T2 =750K
78× 21 / 900 = 45×V2 / 750
1638/900 = 45 V2 / 750
1638×750 = 900×45V2
1228500 = 40500V2
Divide both sides by 40500
1228500÷40500= V2
V2 = 30.33L

Answer:
bcoz iron displaces copper and form the solution iron sulfide
Explanation:
when we dip iron nail in copper sulfate solution,then iron starts reacting with the solution and due to displacement reaction between them iron is stronger metal than copper so it displaces copper and form iron sulfide:
CuSO4+3Fe---->Fe3SO4+Cu
2-Chlorobutane, 2-Bromo-3-methylbutane are chiral .
chiral condition - a compound is said to be chiral if it is surrounded by 4 different groups
I,IV are chiral
II,III are achiral
Molecular types with non-superposable mirror images are known as chiral molecules. The existence of an asymmetric carbon atom in a molecule is the characteristic that most frequently contributes to chirality. When referring to an object that cannot be superposed on its mirror counterpart, the adjective "chiral" is generally employed.
A corkscrew, golf clubs, scissors, and other chiral items all have a "handedness." Thus, one can get scissors and golf clubs that are designed for either hand. Gloves and shoes are also sold in pairs, a right and a left.
