During the water cycle, water is evaporated from the Earth and becomes water vapor. Water vapor then condenses in the air to become clouds. Finally, water returns to the Earth as precipitation
Throughout this process,
A. all of the water is lost.
B. no water is lost.
c. about 50% of the water is lost.
D.
all but a little water is lost.

In which of these cases are the two wave points considered to be in phase with each other?

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

Calculate the standard enthalpy of formation of liquid methanol, ch3oh(l), using the following information: c(graphite) + o2 latex: \longrightarrow ⟶ co2(g) latex: \delta δ h° = –393.5 kj/mol h2(g) + o2 latex: \longrightarrow ⟶ h2o(l) latex: \delta δ h° = –285.8 kj/mol ch3oh(l) + o2(g) latex: \longrightarrow ⟶ co2(g) + 2h2o(l) latex: \delta δ h° = –726.4 kj/mol
