Convert these temperatures to Kelvin:
A. -22 °C
b. 206 °C
C. 50 °C
d. 8 °C
Like this
-22°C + 273.15 = 251.15K
206°C + 273.15 = 479.15K
50°C + 273.15 = 323.15K
8°C + 273.15 = 281.15K

If you have 10,000 grams of a substance that decays with a half-life of 14 days, then how much will you have after 28 days?
Round to the nearest whole number.
Answer:
2500g
Explanation:
Half-life like the name suggests cuts the amount by half. So 10,000 grams would be 5,000 grams in one half-life (14 days). But 28 days is two halflives (14 + 14 = 28), thus 5,000 would be cut in half again to finally be 2500 g.

Molly inflates a beach ball to a volume of 8 liters in her air-conditioned house where
the temperature is 19°C. Later that day, Molly takes the beach ball to the beach. The
temperature at the beach was 33°C, and the air pressure at the beach is the same as
it was at the house.
What will happen to Molly's beach ball when she is at the beach?
The temperature at the air-conditioned house is 19° C. The temperature increases to 33° C in the beach. Molly's beach ball's volume will increase with increase in temperature.
What is the Charles law?Charles' law states that volume of gas increase with an increase in the temperature of the gas.
When pressure remain constant, if temperature increases, the volume of the ball will also increase.
Thus, Molly's beach ball's volume will increase with increase in temperature.

Name these compounds according to IUPAC.
IUPAC is the universal nomenclature method that is used to give the names of the chemical compounds. The compounds are ethene, propionaldehyde, and propanone.
What are functional groups?Functional groups are the particular side groups that are added to the main chain to exhibit a specific property and character to the atom. In the first compound, the presence of the double bond makes it alkene, and the two carbons make the compound ethene.
The second compound has an aldehydic group with suffix -al and three carbon making it propanal, similarly, the third compound is propanone as it has ketone as the functional group and three carbon atoms in the chain.
Therefore, the compounds are ethene, propanal, and propanone.

What are radioactive decay series?Series (or family) of natural radioactive decay is the set of elements with unstable nuclei, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.
In this case, natural radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating.

Explanation:
Formula:
[tex]N_t = N_0( { \frac{1}{2} })^{ \frac{t}{t_ \frac{1}{2} } } [/tex]
Where Nt is the amount of substance remaining after time t,
N0 is the amount of substance at time t = 0,
t is the time at which we have to find out how much substance disintegrated from t = 0 to t = t

Given:
N0 = 200g
t= 40 days
t1/2 = 4 days
To find:
Nt =?
Solution:
Substituting given data in above formula,
[tex]N_t = N_0( { \frac{1}{2} })^{ \frac{t}{t_ \frac{1}{2} } } \\ N_t = 200( { \frac{1}{2} })^{ \frac{40}{4 } } \\ N_t = 200 \times 0.0009765625 \\ \boxed{N_t =0.1953125 \: grams} [/tex]

Name these compounds according to IUPAC.
Answer:
10. Butanoic acid
11. Methylpropanoate
Explanation:
In this case first you need to identify the functional group,secondly identify the longest chain that contains the particular functional group:
10. The functional group for this compound is a carboxylic acid due to the "CHO2" group..we have four carbons which makes the parent chain to be butane.since it's acarboxylic acid we replace the "e" at the end to "oic acid".
11. The functional group is ester "RCOOR".For the ester the longest chain is counted from the part of the carboxylic acid which in this case is a propane,and the part from the alcohol becomes a substituent. With esters you replace the "e" at the end of the parent name to "oate". When you write it down you begin with the substituent in this case "methyl" and the rest follows...

When the fish water had pH of 8.0, the hydronium ion concentration is 1.0x 10^-8 mole per liter. What is Hydornium ion con ent ration when water had pH of 7.0
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
Determine hydronium ion concentration when pH = 7
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
