Cation means a positively charged ion. Anion is a negative one
Answer:
1. micro
2. centi
3. milli
4. kilo
Explanation:
Prefixes, in mathematical exponents, are defined as the alphabetical names associated with the mathematical factors. Some examples are as follows:
10⁶ = Mega
10⁹ = Giga
10⁻⁹ = Nano
10⁻¹² = Pico
So, in order to name the metric system prefixes associated with each of the given mathematical factor, we first convert the factor into exponent form and then write its prefix, as follows:
10⁻⁶ = <u>micro</u>
1/100 = 0.01 = 1 x 10⁻² = <u>centi</u>
0.001 = 1 x 10⁻³ = milli
1000 = 1 x 10³ = <u>kilo</u>
Answer:
3.40g/mL
Explanation:
Density is a measure of mass over volume, so to get the density all we have to do is divide the mass by the volume.
21.35g ÷ 6.28 mL = 3.40g/mL

The addition of catalyst in a chemical reaction has 2 functions
1. if you add negative catalyst then the rate of chemical reaction decreases
2. if you add positive catalyst then the rate of chemical reaction increases.
