A scientist performs an experiment on an unknown element. She finds that the unknown element forms an ionic bond with beryllium (Be). She concludes that the unknown element must belong in group 2 of the periodic table. State whether or not you think this result supports her conclusion, and why. (2 points)

Answers

Answer 1

The test result, which shows a bond with beryllium but not lithium, does not support her conclusion.

What is beryllium?

Beryllium basically is a chemical element with the symbol Be and atomic number 4. It is a light, strong, and alkaline metal that is used in alloys, medical equipment, and aerospace components due to its light weight and high strength. It is also used in nuclear reactors as a neutron reflector and absorber.

Beryllium is a group 2 element that forms ionic bonds with nonmetals.

Non-metals are elements ranging from Group 15 to Group 17.

As a result, the unknown element must be from Group 15 to Group 17.

Hence, her conclusion that the unknown element belong to group 2 is wrong.

A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature

What is Gay- Lussac's Law?

A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature. In other words, while the mass is fixed and the volume is constant, the pressure a gas exerts is proportional to the temperature of the gas.

In the year 1808, French scientist Joseph Gay-Lussac created this law. Gay-law Lussac's can be expressed mathematically as follows:

P ∝ T ; P/T = k

Where:

P is the pressure that the gas is applying.

T is the gas's actual temperature, while k is a fixed value.

Example of Gay-Lussac law

The tire pressure of a car increases after driving. This is due to the air inside the tires heating up as a result of friction (a contact force) between the tires and the road. Gay-Law Lussac's states that because the air cannot expand because the tires are effectively fixed-volume containers, the pressure rises.

The temperature inside a pressure cooker is 117°C. Calculate the vapor pressure of water inside the pressure cooker. What would be the temperature inside the pressure cooker if the vapor pressure of water was 2.85 atm?

Answers

The vapor pressure of water at its boiling point 100°C is 1 atm. Then the pressure at 117°C is 1.17 atm and the temperature of water at a pressure of 2.85 atm is 285°C.

What is boiling point ?

Boiling point of a substance is the temperature at which it converts from liquid state to vapor state. At this temperature the vapor pressure of water vapor is equal to the atmospheric pressure that is 1 atm .

The temperature-pressure relation is written as:

P1 /T1 = P2/ T2

Now, the pressure inside the cooker at a temperature of 117°C is calculated as:

(1 atm × 117 °C) / 100 °C = 1.17 atm.

Thus, pressure at 117 °C is 1.17 atm. Then, If the pressure is 2.85 atm, then the temperature of water inside the pressure cooker is calculated as:

(2.85 atm × 117 °C) / 1.17 = 285 °C

Therefore, the temperature at 2.85 atm is 285 °C.

D.) increase in salinity.

Answers

A decrease in temperature could account for the weakening of hurricanes when they reach the Atlantic Ocean. hence option A is the correct answer.

How is Hurricane formed?

There must be warm ocean water and wet, humid air in the area for one to form. When humid air flows upward at a low-pressure zone over warm ocean water, water is released from the air, resulting in storm clouds. The air in a hurricane rotates as it rises.

Hurricanes begin with the evaporation of warm seawater, which causes water to be pumped into the lower atmosphere. When converging winds collide and turn upwards, this humid air is pulled aloft.

Hurricanes arise when warm, moist air rises over sea. Cooler air replaces the rising air. Large clouds and thunderstorms continue to form as a result of this process. Because of the Coriolis Effect, these thunderstorms continue to expand and begin to rotate.

A student standardized a solution of NaOH and found that the concentration was 0.542 M. They then used it to titrate a monoprotic acid. If 50.40 mL of the base was used, how many moles of acid were neutralized? (Do not report your answer in scientific notation)

Answers

Answer:

0.0272 moles

Explanation:

The number of moles of acid that were neutralized can be found by multiplying the volume of the base (in liters) by its concentration (in moles/liter) and then multiplying that value by the stoichiometric coefficient of the acid in the balanced chemical equation for the neutralization reaction.

To begin, we need to convert the volume of the base from milliliters to liters.

50.40 mL = 0.0504 L

Next, we can multiply the volume of the base (in liters) by its concentration (in moles/liter) to find the number of moles of base used in the titration.

0.0504 L * 0.542 M = 0.0272 moles

Since this is a neutralization reaction between a monoprotic acid and a strong base, the acid:base ratio is 1:1.

So the acid that has been neutralized is also 0.0272 moles.

b.BeO

c.MgF2

d.AlCl3

e.Be3N2

Explanation:

So, the main thing with chemical formulas is making sure that the cation and anion's charges will cancel out if you add the total sum of charges together.

For A, halogens only form -1 charge ions, so F will have to be F-. Lithium, being a group 1 element, will form an ion of Na+. Therefore, the formula is NaF.

For B, Beryllium is a Group 2 element that forms +2 charges, while Group 16 elements like O form -2 charges. Therefore, BeO would work as the sum of charges will equal zero.

For C, Magnesium is a Group 2 element, so it has a +2 ion, while fluorine is a halogen, so a -1 charge for the F- ion. So, you need two F- ions to balance out one Mg2+ ion. So, it is MgF2

For D, Aluminum is a Group 13 element, which can form +3 charges. Therefore, Al can form a +3 charge, so that means for Cl- (recall it is a halogen,) it needs three Cl- ions to cancel one Al3+ ion. So, it is AlCl3.

For E, Group 15 elements like N form -3 ions, so the ion for nitrogen is N3-. Beryllium is a Group 2 element, so it is Be2+. The common multiple of 3 and 2 is 6, so you need to find a way to have a +6 and -6 charge. So, three Be2+ ions (totaling a net charge of +6) need to cancel with two N3- ions (again a net charge of -6) to form the compound. Therefore, it is Be3N2.

Answers

The pressure of N2O gas at a density of 3.10 g/L and a temperature of 298 K is 751 mmHg. To calculate the pressure of the N2O gas at a given density and temperature, we can use the ideal gas law: PV = nRT.

We know that the density of the gas is 3.10 g/L, and the temperature is 298 K. To find the pressure, we can assume that the volume of the gas is 1 L, and solve for pressure. where P is the pressure of the gas, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

The density of a gas can be converted to moles using the formula:

Density = m/V

m = Density*V

Now we can use the ideal gas law to calculate the pressure:

P = (mRT)/V

R is the ideal gas constant = 0.0821 L atm K^-1 mol^-1

P = (3.10g0.0821 L atm K^-1 mol^-1298 K)/1 L

Draw the structure for the product of the reaction between 2-butene and hydroiodic acid, HI.

Answers

The product of the reaction between 2-butene and hydroiodic acid (HI) is 2-iodobutane.

The reaction mechanism involves a nucleophilic substitution, where the iodine atom in HI acts as the nucleophile and attacks the carbon atom in the double bond of 2-butene. This results in the formation of a carbocation intermediate, which then undergoes a rearrangement to form 2-iodobutane. The overall reaction can be represented as follows: 2-butene + HI → 2-iodobutane + H2.Nucleophilic substitution is a type of chemical reaction in which a nucleophile (a molecule or ion with a lone pair of electrons) attacks an electron deficient species, known as an electrophile, to form a new chemical bond. In the process, the electrophile's original electron pair is replaced by the nucleophile. Nucleophilic substitution reactions can occur in a variety of ways, such as S N 1, S N 2, and S Ni (where i = 1, 2, or any other number).

M&M's contain the same amount of protons, M&M's are the same hue. In other words, the size represents the various neutron counts.

Atoms of the same chemical element called isotopes each have a distinct mass number.

While isotopes can vary in mass, they never do so in atomic number (the amount of protons). You will use M&Ms to represent atoms because we are unable to see them. These objectives are use in M&Ms to determine the average atomic mass and to observe how different isotopes are.

In this the number show how many M&M's of that color and size are packed into that bags.
