Answer:D the pressure increases
Explanation:
All matter is made of tiny particles called atoms, molecules and ions; the tiny particles in solids are tightly packed and can only vibrate. The particles in liquids also vibrate but are able to move around by rolling over each other and sliding around. In gases, the particles move freely with rapid, random motion.
I would say A. Sulfur dioxide. Local coal burning power plants have been known to change the color of the sky.
D = m / V
D = 2790 g / 205 mL
D = 13.60 g/mL
Answer:
the coefficients in a chemical equation give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of each substance involved in the reaction.
