Which of the following is not used to perform experiments with liquids? a. beakers b. flasks c. graduated cylinders d. rulers

ruler

Explanation:

Option (d) is the correct answer.

Explanation:

When we perform any experiment with liquids then we need to require beakers, flasks and graduated cylinders.

A graduated cylinder is an apparatus that is used to measure the volume of a liquid.

Similarly, a beaker is a glass apparatus with flat bottom usually used to hold a liquid.

And, a flask is a glass bulb with flattened bottom and an elongated neck which is calibrated to hold a set volume at a respective mark on the neck.

A ruler is used to measure the length of a solid substance or distance between the solid substances.

Thus, we can conclude that out of the given options rulers is not used to perform experiments with liquids.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
