Answer : The disadvantage of using hydropower is Land can be flooded, displacing people and wildlife

Explanation :

Hydropower is a renewable source of energy. In hydropower, electricity is generated using the mechanical energy of moving water.

Since the kinetic energy is necessary to move the turbines, it is essential that the hydropower plant is present near a water source which has moving water.

It is the most efficient way of harnessing the energy from naturally available energy sources. It does not produce any waste. It does not pollute water or air.

Since hydropower needs kinetic energy of moving water, there is always a possibility of nearby land getting flooded. This would affect the people and wildlife of nearby areas.

Therefore the disadvantage of using hydropower is that land can be flooded, displacing people and wildlife

Consider the following reaction where K. = 154 at 298 K: 2NO(g) + Brz(9) 2NOBr(g) A reaction mixture was found to contain 2.69x1

bekas [8.4K]

Explanation:

$2NO(g) + Br_2(g)\rightleftharpoons 2NOBr(g)$

Equilibrium constant of reaction = $K=154$

Concentration of NO = $[NO]=\frac{2.69\times 10^{-2} mol}{1 L}=2.69\times 10^{-2} M$

Concentration of bromine gas = $[Br_2]=\frac{3.85\times 10^{-2} mol}{1 L}=3.85\times 10^{-2} M$

Concentration of NOBr gas = $[Br_2]=\frac{9.56\times 10^{-2} mol}{1 L}=9.56\times 10^{-2} M$

The reaction quotient is given as:

$Q=\frac{[NOBr]^2}{[NO]^2[Br_2]}=\frac{(9.56\times 10^{-2} M)^2}{(2.69\times 10^{-2} M)^2\times 3.85\times 10^{-2} M}$

$Q=328.06$

$Q>K$

The reaction will go in backward direction in order to achieve an equilibrium state.

1. In order to reach equilibrium NOBr (g) must be produced. False

2. In order to reach equilibrium K must decrease. False

3. In order to reach equilibrium NO must be produced. True

4. Q. is less than K . False

5. The reaction is at equilibrium. No further reaction will occur. False

The Mass of the mineral is 9.6 grams . The mineral is placed in a graduated cylinder containing 8.0 ml of water . The water rise

ryzh [129]

Answer:

1.2 g/ ml

Explanation:

The volume of the mineral = increase in volume of the water whuich is 16 - 8 = 8mls.

Therefore the mineral's density = 9.6 / 8

= 1.2 g/ ml answer
