Answer is:<span>increase [Cl</span>₂<span>] and remove HCl from the product.
</span>Chemical reaction: Cl₂ + CH₂Cl₂ → CHCl₃(chloroform) + HCl.
According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of reactants decrease (Cl₂) and concentration of
products of chemical reaction increase (CHCl₃) if increase concentration of reactants and decrease concentration of products.
5 meters = 0.005 km
3 grams = 3,000 milligrams
7 meters = 700 centimeters
Im not sure about #4
2.5 meters = 2,500 mm
77 meters # 770 Dec I meters
0.002 cm = 0.02 mm
44 mm = 0.044 meters
Answer:
HfCl3
Explanation:
Step 1
Divide the percent by mass of each element by its relative atomic mass
Hf- 62.2/178.5, Cl-37.4/35.5
0.348, 1.054
Step2
Divide through by the lowest ratio
0.348/0.348, 1.054/0.348
1, 3
Therefore the empirical formula is HfCl3
