A student adds a rectangular block of mass 26.10 g to a graduated cylinder initially filled with 40.1 mL of water, but some water splashes out of the cylinder. As a result, the student reads the new level of the water to be 42.7 ml. Previously, the student had
measured the length, width and height of the block to be 3.0 cm by 1.0 cm by 1.0 cm.
Does the splash cause the volume of the block to be reported as too high or too low, compared to the volume calculated from the
length measurements?

The splash cause the volume of the block to be too high

Explanation:

This is because, from the previous measurement made by the student, the volume of the block is 5.7ml higher.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
