Only CuSO4 conducts electricity in water because it is an ionic compound. The conduction of electricity is due to the ions in the ionic compound. When copper sulphate is dissolved in water, the ions dissociate and conduct electricity.
The others are do not liberate electricity when dissolved in water because ions are not liberated when electricity is passed through their solutions.

I would say CuSO4 or Copper Sulfate, as option 1 is Methane and would create a fire so heat, and the last one is Sugar which doesn't conduct electricity.  And C6H6 I believe is not soluble in water.<span />

Explain why we use 1/12 in finding atomic mass unit ?​
Nat2105 [25]

Answer:

The u (amu is the old unit name) is 1/12 of the weight of an 12C atom. The way the u is chosen ensures that all core and atom masses are multiples of 1(±0.1) u.

Explanation:

Further explanation if needed...

Carbon 12 was chosen because the chemical atomic weights based on C12 are almost identical to the chemical atomic weights based on the natural mix of oxygen. Simply because the atomic mass is defined as 1/12 of the mass of 12C. Others isotopes of carbon (13C mostly, with an abundance of 1.1% approximately) account for an average atomic mass slightly above 12.

if 45.0 ml of 1.50 M Ca(OH)2 are needed to neutralize 25.0 ml of HI of unknown concentration, what is the molarity of the HI?
ipn [44]

Answer:

M of HI = 5.4 M.

Explanation:

  • We have the rule: at neutralization, the no. of millimoles of acid is equal to the no. of millimoles of the base.

<em>(XMV) acid = (XMV) base.</em>

where, X is the no. of (H) or (OH) reproducible in acid or base, respectively.

M is the molarity of the acid or base.

V is the volume of the acid or base.

<em>(XMV) HI = (XMV) Ca(OH)₂.</em>

For HI; X = 1, M = ??? M, V = 25.0 mL.

For Ca(OH)₂, X = 2, M = 1.5 M, V = 45.0 mL.

<em>∴ M of HI = (XMV) Ca(OH)₂ / (XV) HI</em> = (2)(1.5 M)(45.0 mL) / (1)(25.0 mL) = <em>5.4 M.</em>

Draw the mechanism for the acid-catalyzed reaction of acetic acid (ethanoic acid) with the methanol to yield methyl acetate (met
timama [110]

When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the chemical equation

CH₃COOH + CH₃OH ⇄ CH₃COOCH₃ + H₂O

Here

CH₃COOH is Ethanoic acid (Acetic acid)

CH₃OH is Methanol (Methyl Alcohol)

CH₃COOCH₃ is Methyl ethanoate (Methyl Acetate)

H₂O is water

Thus from the above conclusion we can say that When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.
