It would be A) Cl, K, Ar
Because Cl=35,K=39,Ar=40
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
Out of
the following given choices;
A. increasing
the pH of the salt.
B. increasing
the surface area of the salt.
C. increasing
the pressure of the salt.
<span>D. increasing
the temperature of the salt.</span>
The answer is B. When a substance is reduced to smaller
sizes, its surface area to volume ratio increases. Therefore crushing barium
salts to smaller particles increase the surface area on which it reacts with
the acid. This consequently increases the rate of speed of the reaction.
<span>It is true that energy efficient dishwasher is a water
and energy saver than washing dishes by hand. A star-rated dishwasher uses 4
gallons of water in each cycle compare to a kitchen faucets who pumps out 2.5
gallons of water per minute. To conserve water, the accumulated dishes and cookware
must be stack properly in a dishwasher before running a cycle. As to conservation
of energy, people tend to use warm water to wash the dishes by hand and heating
of water cost much, while in a dishwasher, energy-saving tips such as running a
light cycle and turning off heating drying option will mark down your energy
consumption. Therefore, the use of dishwasher is a much greener idea. </span>
