Its not pure water, it has other minerals and elements in it whose boiling point may be above 100 degrees
Answer:
D. 17
Explanation:
Halogens (group 17) are most likely to form a -1 ion. This is because they want to complete their octet. A prime example of this is sodium chloride. Sodium chloride is an ionic compound. Sodium gives up its valence electron, therefore, recieving a +1 charge, and Chlorine takes it, giving it a -1 charge. Chlorine is also in group 17, halogens.
The ice will require two forms of heat: latent to melt and sensible to be heated to 50 °C.
Q(ice) = ml + mCpΔT
= 150 x 333 + 150 x 4.18 x 50
= 85950 Joules
The mass of steam must release this much energy in two forms: latent to fuse into water and then sensible to cool to 50 °C.
85950 = m(2256) + 4.18 x 50 x m
m = 34.9 grams of steam.
Answer:
H20
Explanation:
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients
Empirical evidence is information acquired by observation or experimentation
