17.4 mL of unknown H2SO4 solution was titrated by 0.20 M of NaOH. 41.51 mL of that NaOH solution was consumed to exactly completely neutralize the acid. What is the original molarity (in M) of the unknown H2SO4 solution?

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.

Which element would mostly likely have an electron affinity measuring closest to zero
