Answer:

The errors in the table are: Skin cancer is infectious (which is wrong), Flu is noninfectious (which is wrong), and AID is noninfectious (which is also a wrong statement). There are three (3) wrong statements in this table.

Explanation:

Skin cancer is caused by the loss of divisional control mechanism possessed by healthy cells, which makes the cell to defer apoptosis or programmed cell death, and tend to multiply at a faster uncontrollable rate and eventually lead to tumors. This is due to an alteration to the genetic makeup at the segment that controls cell division in the DNA. This problem cannot be passed to others since it is not by an external infectious agent such as bacteria or viruses.

FLU is caused by the contagious viral agent called the Influenza virus; it can be transmitted from an infected individual to a healthy person; it is infectious. Likewise, AIDS, which is Acquired Immune Deficiency Syndrome, is caused by the highly infectious virus called Human Immunodeficiency Virus.

How many joules of energy would it take to raise the temperature of 2.5 grams of magnesium metal from
garik1379 [7]

Answer:

Q = 63.75J

Explanation:

Mass = 2.5g

Initial temperature (T1) = 25°C

Final temperature (T2) = 50°C

Specific heat capacity of Mg = 1.020J/g°C

Heat energy = ?

Heat Energy (Q) = mc∇T

Q = heat energy

M = mass of substance

C = specific heat capacity of substance

∇T = change in temperature = T2 - T1

Q = mc∇T

Q = mc(T2 - T1)

Q = 2.5 × 1.020 × (50 - 25)

Q = 2.55 × 25

Q = 63.75J

The heat energy required to raise magnesium metal from 25°C to 50°C is 63.75J

What is the IUPAC name of the following compound?
pentagon [3]

Answer:

(d) 3,7-dimethyl-4-nonyne.

Explanation:

Hello,

In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.

Best regards.

PLEASE HELP MEDALS WILL BE AWARDED!!!

Mole percent of O2 = 10% = 0.1 moles
Mole percent of N2 = 10% = 0.1 moles
Mole percent of He = 80% = 0.8 moles
Molar Mass of O2 = (2 x 16) x 0.1 = 3.2
Molar Mass of N2 = (2 x 14) x 0.1 = 2.8
Molar Mass of He = 4 x 0.8 = 3.2
1. Molar Mass of the mixture = 3.2 + 2.8 + 3.2 = 9.2 grams
2. Since at constant volume density is proportional to mass, so the ratio of
mass will be the ratio of density.
Ratio = Molar Mass of the mixture / Molar Mass of O2 = 9.2 / 32 = 0.2875
