Answer:

d. 10

Explanation:

The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12

Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.

The confusing thing is that + means subtract and - means add here.

Answer:

0.2491

Explanation:

1mole of a gas contains 6.02 × 10²³molecules

x moles will contain 3.408 × 10²¹

x = 1 × 3.408 × 10²¹/ 6.02 × 10²³

= 5.66 × 10^-3moles

Mole = mass/ molar mass

mass = Mole × molar mass

= 5.66 × 10^-3 × 44.01

= 249.0966 × 10^-3

= 0.2490966

Of the following, ________ is the most volatile. Select one: C2F6 C2H6 C2I6 C2Cl6 C2Br6

Answers

Answer:

C2Br6

because bromine is a liquid volatile

According to the forces of attraction and boiling point C₂Br₆ is most volatile as its boiling point is very low.

What are forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

When 2.0 mol of methanol is dissolved in 45 grams of water, what is the mole fraction of methanol

Answers

The mole fraction of methanol in the mixture is 0.444

We'll begin by calculating the number of mole of water.

Mass of water = 45 gMolar mass of water = 18 g/molMole of water =?

Mole = mass / molar mass

Mole of water = 45 / 18

Mole of water = 2.5 moles

Finally, we shall determine the mole fraction of methanol.

Mole of water = 2.5 molesMole of methanol = 2 molesTotal mole = 2 + 2.5 = 4.5 moles

Mole fraction of methanol =?

Mole fraction = mole / total mole

Mole fraction of methanol = 2 / 4.5

Mole fraction of methanol = 0.444

Thus, the mole fraction of methanol is 0.444

An hibernating bear accumulates 25 kg of a triglyceride (846 g/mol) comprising the following fatty acids: C16, C17 and C18∆9. How many grams of β-hydroxybutyrate (104 g/mol) can the bear produce from this triglyceride during its hibernation?

Answers

The quantity of β-hydroxybutyrate the bear can produce

during hibernation is 3,073.30grams.

Hibernation is defined as the period of less activity by animals to conserve energy to survive coarse weather conditions.

A typical example of an animal that hibernates is the bear.

From the question, a bear is able to accumulate 25kg (25000grams) of triglyceride.

To calculate quantity of β-hydroxybutyrate that would be produced from 25kg triglyceride;

846g of triglyceride = 104grams of β-hydroxybutyrate

25000g of triglyceride = x grams

(Cross multiple to solve for x grams)

X = 104 × 25000/846

[tex]x = \frac{104 \times 25000}{846} [/tex]

[tex]x = \frac{2600000}{846} [/tex]

[tex]x = 3073.30grams[/tex]

Therefore, the quantity of β-hydroxybutyrate the bear can produce during hibernation is 3,073.30grams.

C. The temperature of the water will remain constant as it boils.
D. The temperature will increase as it boils.

Answers

B. water will boil at a lower temperature on Venus than on Earth.
Explanation:
Because temperature and pressure are directly proportional... increase in pressure will increase in the atmospheric temperature.... Venus has higher pressure than earth that also means it has higher atmospheric temperature and as the temperature is already high the water will require lesser heat to boil

Of the following which displays a positive energetic process?

Answers

We can describe a positive energetic process as any process which increases the internal energy of the system.

A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:

Boiling an EggRoasting food over a fire (the food is the reference system)

etc

Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.
