Answer:
100mL of chloromethane
Explanation:
Based on the equation:
Cl₂(g) + CH₄(g) → HCl(g) + CH₃Cl(g)
<em>1 mole of chlorine reacts per mole of methane to produce 1 mole of HCl and 1 mole of chloromethane</em>
<em />
Avogadro's law says that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. Using Avogadro's law we can say of the equation that:
<em>1 mL of chlorine reacts per mL of methane to produce 1 mL of HCl and 1 mL of chloromethane</em>
Because the system stays under constant pressure and temperature.
As 100mL of Cl₂ reacts with excess of CH₄ and 1mL of Cl₂ produce 1mL of CH₃Cl there are produced:
<h3>100mL of chloromethane</h3>
Answer:
iv. -NH₂
Explanation:
The amine group is an activating substituent and provides an <em>ortho-para </em>orientation.
The free electrons in the nitrogen atom provide <u>stabilization by resonance </u>in the sigma complex if the attack by the electrophilic reactant occurs in the positions <em>ortho</em> or <em>para </em>with regards to the nitrogen atom.
Answer:
Spraying perfume in one corner of the room and the smell travels to the other side of the room
Explanation:
Answer:
19.8 kg of C₂H₂ is needed
Explanation:
We solve this by a rule of three:
If 1251 kJ of heat are relased in the combustion of 1 mol of acetylene
95.5×10⁴ kJ of heat may be released by the combustion of
(95.5×10⁴ kJ . 1) /1251kJ = 763.4 moles of C₂H₂
Let's convert the moles to mass → 763.4 mol . 26 g/1 mol = 19848 g
If we convert the mass from g to kg → 19848 g . 1kg / 1000g = 19.8 kg
