- Heterogeneous Equilibria in the System Mm(BUO5) m� nH2O-Aqueous HCl. Chernorukov, N.; Nipruk, O.; Knyazev, A.; Khomyakova, V. // Russian Journal of General Chemistry;Jan2005, Vol. 75 Issue 1, p40
A quantitative model of the system crystalline uranoborate-aqueous solution was proposed on the basis of the experimental solubilities of M m(BUO5) m� nH2O (Mm are alkaline and alkaline-earth metals) in aqueous HCl at 25�C. The model was used to predict the state of the heterogeneous systems...

- THE EARTH. Coupe, Robert // Planets;2003, p14
Earth's surface is mostly covered with water. It is away from the sun. If the earth were closer to the sun, it would be too hot for water to exist. However, if it were further away, water would be frozen as ice.
- MARS. Coupe, Robert // Planets;2003, p18
The warmest days are extremely cold on mars. A day on this planet is about as long as a day on earth. Scientists believe that only the simplest forms of life could exist on the planet.
