Answer:

Ionization energy is the energy required to remove the most loosely bound electron from an isolated gaseous atom.

The ionization energy decreases as the size increases. The electrons get added to the new shell and the nuclear charge increases. But the effect of addition of new sheels overcomes the increase of nuclear charge.The valence shell moves far from the nucleus.

Thus the valence electron gets less tightly held by the nucleus and thus less energy is required to remove the valence electron.

Shielding effect can be defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces of the electrons on the nucleus. Thus as the size increases and the electrons move away from nucleus, the attractive forces decrease.

Answer:

the volume stays the same, but the shape changes to fit the new container

Explanation:

because the same amount/volume of liquid is being placed in a new container, the new container has a different shape to the old, thus changing the liquids shape but not volume.

Answer:

C5H12 + 8 O2 → 5 CO2 + 6 H2O

Moles of pentane = 35.45 g / 72.15 g/mol = 0.491 mol

Moles of oxygen = 25 g / 32 g/mol = 0.781 mol

Mole ratio of oxygen to pentane is 8:1, so we need 8 moles of oxygen for every mole of pentane. Since we have 0.491 moles of pentane, we need 3.928 moles of oxygen. However, we only have 0.781 moles of oxygen, which means oxygen is the limiting reactant.

To calculate the grams of oxygen that react, we can use the mole ratio of oxygen to pentane:

0.491 mol C5H12 × (8 mol O2 / 1 mol C5H12) × (32 g/mol) = 125.44 g O2

The amount of excess reactant left over can be calculated by subtracting the moles of the limiting reactant from the moles of the excess reactant:

Moles of excess oxygen = 0.781 mol O2 - 0.0614 mol O2 = 0.7196 mol O2

Grams of excess oxygen = 0.7196 mol × 32 g/mol = 23.03 g O2

Therefore, 125.44 grams of oxygen react, and 23.03 grams of oxygen are left over.

   2. The amount of energy released can be calculated by multiplying the amount of moles of pentane by the heat of combustion:

0.491 mol C5H12 × (-173.5 kJ/mol) = -85.17 kJ

Therefore, 85.17 kJ of energy is released during the combustion reaction.

Combustible liquids are much less volatile than flammable liquids, which rapidly catch fire and burn at room temperature.

Answer:

118 g of Ar; 28.8 g of \(NO_{2}\)

Explanation:

To convert from moles to grams, you simply multiply by the atomic mass. So the conversion table looks as follows:

\(\frac{2.95 mol}{1} *\frac{39.95 g}{1 mol}\)

The mol units cancel, and you are left with 118 g of Argon (117.8525 without sig-figs).

As for the next part of our problem, the first thing we need to do is find the molar mass of \(NO_{2}\). e can do this by adding the weight of all the atoms within the compound:

N + 2(O) = (14.01) + 2(16) = 46.01 g

Then, we repeat the above process, except we use the molar mass we just found instead of the atomic weight:

\(\frac{0.627 mol}{1}*\frac{46.01 g}{1 mol}\)

Once again, the mol units cancel, and we are left with 28.8 g of \(NO_{2}\) (28.84827 before sig-figs).

The four complementary characteristics of colligative properties that a solution can display are an increase in boiling point, a decrease in freezing point, a relative decrease in vapor pressure, and an increase in osmotic pressure.

What are colligative properties?

Some characteristics of diluted solutions containing non-volatile solutes depend only on the quantity of solute particles present and not on the solute type. Collaborative qualities are what these traits are known as. Most frequently, diluted solutions exhibit these characteristics.

Collaborative properties can also be defined as those that result from the dissolution of a non-volatile solute in a volatile solvent. Typically, the solute alters the characteristics of the solvent by removing some of the solvent molecules from the liquid phase. Additionally, the concentration of the solvent is reduced as a result of this.

Answer:

The average rate of climb in miles per minute is 8.2x10⁻⁴ miles/min.

Explanation:

The average rate can be calculated as follows:

\( \overline{v} = \frac{y_{f} - y_{0}}{t_{f} - t_{0}} \)

Where:

\(y_{0}\): is the initial height = 24976 ft

\(y_{f}\): is the final height = 29035 ft

\(t_{0}\): is the initial time = 0

\(t_{f}\): is the final time = 15 hr, 35 min = 935 min      

Then, the average rate of climb in miles per minute is:

\( \overline{v} = \frac{y_{f} - y_{0}}{t_{f} - t_{0}} \)

\( \overline{v} = \frac{29035 ft - 24976 ft}{935 min - 0} = 4.34 \frac{ft}{min}*\frac{1 mile}{5280 ft} = 8.2 \cdot 10^{-4} miles/min \)      

Therefore, the average rate of climb in miles per minute is 8.2x10⁻⁴ miles/min.

The addition of a sample of compound A to compound X not lowering the melting point of X does not necessarily mean that X is identical to A.

The answer is yes, if the addition of compound A to compound X does not lower the melting point of X, it suggests that both compounds are identical. This observation is based on the principle that when two different compounds are mixed, their melting point usually decreases due to impurities or differing molecular interactions. However, if the melting points remain the same, it indicates that the compounds are likely the same. It could simply mean that the two compounds do not have a significant effect on each other's melting points. Other factors, such as the amount and nature of impurities in each compound, could also influence their melting points. Therefore, additional testing and analysis would be necessary to determine if X is indeed identical to A.

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent.Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating
