input: OPTIONS:
- microscope
- bunsen burner
- microtome
- electroscope Now, answer this question: Answer the following question given this paragraph: A laboratory instrument used to analyze and test for static charge is called an electroscope. Seen below, an electroscope consists of a metal knob connected by a metal stem to two very lightweight pieces of metal called leaves, shown in yellow. The leaves are enclosed in a box to eliminate stray air currents. Q: What laboratory instrument is used to analyze and test for static charge? A:
A:
output: electroscope

input: OPTIONS:
- notations
- superscripts
- hybrids
- subscripts Now, answer this question: Answer the following question given this paragraph: Crossing charges. One method for obtaining subscripts in the empirical formula is by crossing charges. When crossing charges, you will sometimes find it necessary to reduce the subscripts to their simplest ratio to write the empirical formula. Consider, for example, the compound formed by Mg2+ and O2. Using the absolute values of the charges on the ions as subscripts gives the formula Mg2O2:. Q: Crossing charges is one method for obtaining what? A:
A:
output:
subscripts
