D would be your answer.
Lithium has a valence electrons of one.
Sulfur has two valence electrons.

Answer:

D

Explanation:

Lithium has one valence electron, so it has one to give away to have an outer shell of 8.

Sulfur has 6 valence electrons, so it needs 2 to get an outer shell of 8.

If we have two Li, that means sulfur will get 2 e- and Li will give away 2 e-, so the formula is Li₂S.

True or False: Adding 4.18 joules to water will increase the temperature more than adding 1 calorie to water.
mote1985 [20]

Answer:

Because one calorie is equal to 4.18 J, it takes 4.18 J to raise the temperature of one gram of water by 1°C. In joules, water's specific heat is 4.18 J per gram per °C. If you look at the specific heat graph shown below, you will see that 4.18 is an unusually large value.
