My question is A 25 mL sample of 0.100 M HNO3 completely reacts with NaOH according to this equation:

HNO3(aq) + NaOH (aq) ⟶ NaNO3(aq) + H2O(l)

What volume of 0.0500 M NaOH solution is required to completely react with the HNO3

2.50 mL NaOH
5.00 mL NaOH

25.0 mL NaOH

50.0 mL NaOH

Examine the following sets of events. set a: {1, 5, 7, 9, 14} set b: {2, 5, 6, 8, 14, 17} which of the following represents the intersection of set a and set b ? {∅} {5, 14} {1, 2, 5, 6, 7, 8, 9, 14, 17} {1, 2, 6, 7, 8, 9, 17}

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
