LED light bulb is more energy efficient than CFL bulb simply because they are based on better technology. LED light bulbs use much lesser energy in comparison to the traditional technology.
Answer:
The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
Explanation:
first there is only 25 points on here because if you add 50 points to the question brainly divides it by two so that two people can answer so if you want each person to get 50 points or to advertise how much point sis on this quetstion you would instead need to add 100 points to the question- anyways let's answer this question now
Do you know what the Law of Conservation of mass says? Matter is neither created nor destroyed. Therefore, you have started with 12.7 g Cu and 3.2 g S on the left for a total of 15.9 g; therefore, you must obtain 15.9 g of product(s). If Cu2S is the only product there must be 15.9 g Cu2S.
Molar mass Chlorine ( Cl ) = 35.45 g/mol
hope this helps!
