Answer:
See below
Explanation:
1 minute is 4 halflives ( because 4 x 15 sec = 1 minute)
(1/2)^4 = 1/16
you will have 1/16 as many M&M as you started
A major factor in how the periodic table<span> is organized is the configuration of each </span>element's<span> valence electrons. Because </span>elements<span> in each family have the same number of valence electrons, they tend to have several similar </span>characteristics<span>.</span>
Answer:
a) 0.03050 = 3.050 × 10-²
b) 0.256 x 10°= 2.56 × 10-¹
c) 25.005 10 = 2.500510 × 10¹
Explanation:
Scientific notations is a way of making very large or very small numbers more comprehensive or simplified. It involves the use of power of ten (10^). The numbers are represented to the power of ten. The following format is used:
a x 10^b
where; a is a number or decimal number between 1 and 10 i.e less than 10 but greater than 1
b is the power of ten
To write a number in scientific notation,
- we move the decimal point right or left depending on whether we're trying to reduce or increase the number
- we count the number of times the decimal point was moved. This serves as the b in the format above.
For example,
a) 0.03050 = 3.050 × 10-²
The decimal point was moved rightward twice. This caused the ^-2 power.
b) 0.256 x 10°= 2.56 × 10-¹
The decimal point was moved rightward once. This caused the ^-1 power.
c) 25.005 10 = 2.500510 × 10¹
The decimal point was moved leftward once. This caused the ^1 power.
London dispersion is present, as we can see C3H5(OH)3 is very branched, when a molecule is branched it has a low boiling point due to how compact the surface area is compare to C3H7OH which has a large surface area (in this molecule there is only on branch)
