Explanation:
Volume of solid metal = 102.6ml - 100ml = 2.6ml.
Mass of solid metal = 50g.
Density = Mass / Volume = 50g / 2.6ml = 19.2g / cm³.
Also from our knowledge, only gold metal is yellowish here.
Hence the answer is gold metal.
A substitution reaction has two steps, and doubling the concentration of the alkyl halide is found to double the reaction rate. This is a bimolecular SN2 reaction is a false statement.
<h3>What is substitution reaction?</h3>
Substitution reaction is a single step reaction in which one functional group is substitute by another functional group. An example is halogenation reactions, in which a functional group is replaced by a halogen.
Thus, the statement is false.

Answer: Option (B) is the correct answer.
Explanation:
According to the given reaction equation, formula to calculate is as follows.
= coefficients of gaseous products - gaseous reactants
= 1 - 0
= 1
Also we know that,
For the equation,
Activity of solid and liquid = 1
As,
Hence, = 0.0056 atm
Thus, we can conclude that partial pressure of oxygen gas at equilibrium is 0.0056 atm.
Hey there!:
mass = 41.2 g
Volume = 8.2 cm³
Therefore:
D = m / V
D = 41.2 / 8.2
D = 5.02 g/cm³
Answer:Sodium chloride has higher boiling point than Potassium chloride.
Explanation:This is due because potassium is larger than sodium,which means that sodium chloride has higher lattice energy in comparison to potassium chloride.
