Answer:
<h2>Physical properties: H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form.</h2>
Answer:
True
Explanation:
According to some calculations, the Earth is losing 50,000 metric tons of mass every single year, even though an extra 40,000 metric tons of space dust converge onto the Earth's gravity well, it's still losing weight.
Answer:
movement of water from an area of lower solute concentration to an area of higher solute concentration
Explanation:
suppose two compartments separated by a semipermeable membrane, so that one contains water (compartment A) and the other a concentrated saline solution (compartment B). In this situation there is a greater chemical potential of the water present in A, which manifests itself as a diffusion tendency towards B, diluting this solution accordingly.
Answer: 12 moles
Explanation: reaction C3H8+ 5 O2 ⇒ 3 CO2 + 4 H2O
1 mole propane produces 3 mol CO2. For 36 mol
Is 12 moles needed
When the energy of the products is higher than the energy of the reactants then it means the reaction is endothermic. In the graph it can be seen as having a higher energy at the end than the initial energy. If the opposite is observed then the reaction is exothermic.
