A standard nitric acid solution is prepared using 0.425g of sodium carbonate, na2co3. Find the molarity of the acid uf 33.25ml are required to reach a permanent endpoint.

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.
