For the discovery of the elements polonium and radium. Prohibited from higher education in her native Poland (then controlled by Russia), she moved to Paris in 1891 and studied at the Sorbonne.
Following steps are involved in the reaction
Step 1: <span>Cl2(g)⇌2Cl(g)
Step 2: </span><span>Cl(g)+CHCl3(g)→HCl(g)+CCl3(g)
Step 3: </span><span>Cl(g)+CCl3(g)→CCl4(g)
......................................................................................................
Overall reaction : </span>Cl2(g) + CHCl3(g) → HCl(g) + CCl4(g)
Note: Overall reaction is obtained by adding step 1-3 and canceling common terms that are present on reactant and product sides.
Answer: Option (a) is the correct answer.
Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is
and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.

Thus, we can conclude that out of the given options
is the correct equation for the dissociation of water.
Answer:
133 g
Explanation:
Step 1: Write the balanced equation
2 Al(s) + 3 Br₂(l) ⇒ 2 AlBr₃(s)
Step 2: Calculate the moles corresponding to 15.0 g of Al
The molar mass of aluminum is 26.98 g/mol. The moles corresponding to 15.0 g of Al are:

Step 3: Calculate the moles of Br₂ that react with 0.556 moles of Al
The molar ratio of Al to Br₂ is 2:3. The moles of bromine that react with 0.556 moles of aluminum are:

Step 4: Calculate the mass corresponding to 0.834 moles of Br₂
The molar mass of bromine is 159.81 g/mol. The mass corresponding to 0.834 moles of Br₂ is:

Answer is A have a crystal structure.
