Out of the available answers, the most likely correct would be that
eventually everyone must sleep due to our need for mental rest. However,
it is not as simple as this, as all of the processes implicated with
mental rest (including the restoration of biological rhythms as
mentioned in an alternative answer) cannot necessarily be summed up in
this way.
Grass planting, laying of straw , putting up sediment fenced or knee high black fabric fences can help reduce no point source water pollution
Answer:
Explanation:
a) The forward reaction is exothermic, hence when temperature is increased the equilibrium shift towards the reactants side to get rid of the excess energy. This will mean that more reactants are produced decreasing yield
b) There are a fewer number of moles of gas on the right side compared to the left side (Just count the coefficients before each compound) so a higher pressure will mean that the equilibrium will shift towards the products side in order to decrease the pressure. This will mean that more products are formed increasing yield
c) When something is powdered it's surface area to volume ratio increases. A higher surface area means that the particles around it have more area to work on so the frequency of collisions will increase increasing the rate of reaction. This is why iron is powdered.
A. Cesium because reactivity of alkali metals increases from the top to the bottom of the group.
