If 146.5 g of chromium(lll) chlorate decomposes, what mass of oxygen can be produced?
Vinil7 [7]

Answer:

The Equation for this reaction is as follow,

                               2 Cr(ClO₃)₃    →    2 CrCl₃  +  9 O₂

According to eq,

      604.68 g (2mole) of Cr(ClO₃)₃ produces  =  288 g (9 moles) of O₂

So,

                 146.5 g of Cr(ClO₃)₃ will produce  =  X g of O₂

Solving for X,

                             X  = (146.5 g × 288 g) ÷ 604.68 g

                    X  =  69.77 g of O₂

Identical wire loops are dipped into Liquid X and Liquid Y, so that a film of liquid forms across the loops (like the bubble sol
muminat

Answer:

a.

Explanation:

Assuming that Liquid X is considered to possess a greater viscosity as well as higher surface tension than liquid Y. Then, liquid X will tend to harbour more pressure inside the liquid.

In addition to that, the greater the surface tension, the greater the force required to expand the liquid's surface area.

This in turn makes the force required to make the loop 5% wider to be greater in FX rather than FY.

Thus, option a is the correct answer.
