Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many g of hydrogen gas are formed when 125.0 g of sodium are added to water? 2Na + 2H2O → 2NaOH + H2

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
