If you divide 8.1 by 1.8 that leads to 4.5
Following reaction arise between Br2 and Cl2
Br2 + Cl2 → 2BrCl
(1mole) (1mole) (2moles)
From above balanced reaction, it can be seen that 1 mole of Br2 reacts with 1 mole of Cl2 to form 2 mole of BrCl
Thus, when <span>2.74 mol Cl2 reacts with excess Br2, 2.74 X 2 = 5.48 moles of BrCl will be formed. </span>
Answer:
286 kPa
Explanation:
Boyles law states that volume of gas is inversely proportional to pressure o gas for a fixed amount of gas at constant temperature
P1V1 = P2V2
where P1 is pressure and V1 is volume at first instance
P2 is pressure and V2 is volume at the second instance
substituting the values in the equation
229 kPa x 4.0 L = P2 x 3.2 L
P2 = 286.25 kPa
the new pressure is 286 kPa
It really depends on the 'type' of rock it is. By this I mean whether it's impermeable or permeable. Impermeable rocks don't allow water through and permeable rocks do. It has to do with how 'porous' a rock is: how many openings it has and how spaced apart are its particles are. Sandstone is permeable and Shale impermeable.
