A homogeneous mixture has the same uniform appearance and composition throughout
A heterogeneous mixture consists of visibly different substances or phases.
The ionic radius increases.
Each time you move down to the next Period, you are adding an extra shell of electrons.
Each shell is further from the nucleus than the one before it, so the .
The image below illustrates the increase in ionic radius as you go down a Group.
Answer:
The overall cell potential must be positive.
Explanation:
What must be true for a spontaneous reaction in an electrochemical cell?
- The overall cell potential must be positive. YES. This is by convention.
- The overall cell potential must be negative. NO. By convention, a negative cell potential means the cell is not spontaneous.
- The cathode’s standard reduction potential must be positive. NO. It only has to be higher than the anode's standard reduction potential.
- The cathode’s standard reduction potential must be negative. NO. It only has to be higher than the anode's standard reduction potential.
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>
It would have filtered already within the time frame of 2 to 3 hours because of the molecular injection ignited by the co2 within the strip so you would observe the UNDERSIDE OF THE PAPER and the molecular tear within it
