a sample contains of 14.2g chlorine gas.What is the volume of chlorine gas at room temperature and pressure? [Relative atomic mass,Cl=35.5;Molar volume of gas=24dm³ mol^-1 at room temperature and pressure

Aqueous solution of sodium hypochlorite (NaOCl) is a household bleach and is a strong oxidizing agent that reacts with chromite ion Cr(OH)_(4)^(-)in basic solution to yield chromate (CrO_(4)^(2-)) and chloride ion.

Based on the above statement select the correct statement:

A) It is simply a disproportionation reaction

B) OCL- has been reduced and Cr(OH)_(4)^(-) has been oxidised

C) It is simply a neutralisation reaction

D) OCL- has been oxidised and Cr(OH)_(4)^(-) has been reduced

Given the following reactions solve for the equivalent weight of each of the substances listed. Show your solution.

Ca (OH)2 + 2H3PO4 → Ca(H2PO4)2 + H2O

Cr2O72- + C2O42- + H+ → Cr3+ + CO2 + H2O

Ni2+ + 4CN- → [Ni (CN)4]2+

1. H3PO4 4. Ca (OH)2

2. KCr2O7 5. NaCN

3. KHC2O4 6. NiCl2
