are the 14 transition metals that follow lanthanum in the periodic table.
Answer: Lanthanide or Lanthanides
Explanation: Sorry that I don’t have an explanation. I just answered the question correctly myself. <33
The lanthanide and actinide are present in the periodic table as a transition metals.
What is periodic table?Periodic table is defined as a tabular arrangement of chemical elements ordered by increasing atomic number and element groups.
The latest periodic table has an ordered grouping of the 118 known chemical elements.
Lanthanide is defined as any of the elements with rising atomic numbers beginning with lanthanum or cerium and ending with lutetium.
Lanthanide are rarely found on earth i.e. they are called rare earth metals.
Actinide is defined as any of the elements with increasing atomic numbers beginning with actinium or thorium and ending with lawrencium.
Actinide are the radioactive metals.
Thus, the lanthanide and actinide are present in the periodic table as a transition metals.

when dilute HCL is added to zinc pieces taken in a test tube
Answer:
zince chloride will be formed and hydrogen gas will be librated.
Explanation:
When dilute HCl is added to zinc pieces, a rection will takes place as follows :
[tex]Zn+HCl\rightarrow ZnCl_2+H_2[/tex]
It means that zinc chloride will form when zinc reacts with dilute HCL. Also hydrogen gas will produced.
As zinc is more reactive than hydrogen, it displaces hydrogen from its solution and forms zinc chloride. The form product is white in color and H₂ is an odorless gas.
Hence, zince chloride will be formed and hydrogen gas will be librated.

When a machine does work, a trade-off occurs. Which of the following best exemplifies this trade-off?
A. A pulley changes the direction of your force, but requires a greater input force.
B. A lever increases output force and the distance the load moves.
C. A wheel and axle increases output force and the distance the load moves.
D. A ramp allows you to decrease force, but requires a greater distance.
Answer:
A
A pulley changes the direction of your force, but requires a greater input force.
Explanation:
A pulley changes the direction of your force, but requires a greater input force when machine does work. so option A is correct.
What is machine ?Any tool that makes work easier is a machine. We can complete tasks with the aid of machines by using less force and energy.
By using a simple machine, you can move anything with less effort, but you have to move it farther to do the same amount of labor.
Our bodies function like machinery. For instance, our arms can be compared to a machine that can be utilized to quickly lift objects.
By using a machine to perform work, either the force or the distance across which the force is delivered may rise, but not both at once. In other words, as one grows, either force or distance, the other must decrease. The force-distance trade off is what is meant by this.
Thus, option A is correct.

Which of the following changes would double the force between two charged particles
Answer:
Decreasing the distance between the particles by a factor of 2
Explanation:
To double the force between the two charge particles, the distance between the particles should be reduced by a factor of two.
According to coulombs law "force is directly proportional to the potential between the two charges and inversely proportional to the square of their distances".
F = [tex]\frac{kq_{1} q_{2} }{r^{2} }[/tex]
F is the electric force
k is the coulomb constant
q is the charge
r is the distance or separation
As the separation between the charges is reduced the force increases and vice versa

Commercial scuba divers use tanks filled with a mixture of gases known as Trimix on very long, deep dives. Trimix is composed of 70% nitrogen, 10% oxygen and 20% helium. The total pressure of the Trimix inside a certain tank at the beginning of the dive is 118.4 atm. A. What is the partial pressure of the oxygen in the tank?
Answer:
Partial pressure of O = 11.84 atm
Explanation:
To solve the excersise we think in the partial pressure law with mole fraction.
Mole fraction of gas = Partial pressure of gas / Total pressure
We have data of all the mole fractions:
0.70 N0.10 O0.20 HLet's find out the partial pressure of oxygen in the tank. We replace data in the formula:
0.10 = Partial pressure of gas / 118.4 atm
0.10 . 118.4 atm = Partial pressure of gas → 11.84 atm
If we determine all the partial pressures:
0.70 . 118.4 atm = 82.88 atm → Partial pressure N
0.20 . 118.4 atm = 23.68 atm → Partial pressure He
We can determine the partial pressure of the trimix.
Sum of partial pressures of each gas = Total pressure of the mix
11.84 atm + 82.88 atm + 23.68 atm = 118.4 atm
(A way to see, if our operations were ok)
The partial pressure of oxygen in the tank is required.
The partial pressure of the oxygen in the tank is 11.84 atm.
[tex]x_o[/tex] = The mole fraction of oxygen = 10%
[tex]p[/tex] = The total partial pressure in the tank = 118.4 atm
The mole fraction of a gas is equal to the ratio of partial pressure of the gas to the total partial pressure.
[tex]x_o=\dfrac{p_o}{p}\\\Rightarrow p_o=x_op\\\Rightarrow p_o=0.1\times 118.4\\\Rightarrow p_o=11.84\ \text{atm}[/tex]
The partial pressure of the oxygen in the tank is 11.84 atm.

If 56 grams of nitrogen is mixed with 56 grams of oxygen, what is the pressure of each gas if the total
pressure is 1320 Torrs?
Answer:
pN₂ = 695 torr; pO₂ = 625 torr
Explanation:
Step 1: Calculate the moles of each gas
The molar mass of N₂ is 28.01 g/mol.
56 g × 1 mol/28.01 g = 2.0 mol
The molar mass of O₂ is 32.00 g/mol.
56 g × 1 mol/32.00 g = 1.8 mol
Step 2: Calculate the total number of moles
n = nO₂ + nN₂ = 1.8 mol + 2.0 mol = 3.8 mol
Step 3: Calculate the partial pressure of each gas
We will use the following expressions.
pN₂ = P × X(N₂)
pN₂ = 1320 torr × (2.0 mol/3.8 mol)
pN₂ = 695 torr
pO₂ = P × X(O₂)
pO₂ = 1320 torr × (1.8 mol/3.8 mol)
pO₂ = 625 torr

Answer:
The correct options are;
1) Hierarchical
2) Frustration
3) Attraction

5) Bridging
Explanation:
A career can be defined as a person's trade or occupation, which he or she engages and progresses in for a considerable portion of his or her life
When a person is engaged in a career that is not best suited to them can therefore lead to frustration, due to the length of time required in building a career
Agriculture, veterinary and nursing are mainly hands on or time input (for agriculture) careers, that seek to attract young people
The existence of poor health and safety conditions in an organization limits the advancement of individuals in their chosen career within the organization
Therefore, we have;
Career is a sequence of related jobs arranged in a hierarchical order
Wrong choice of career may lead to frustration
Agriculture, veterinary, and nursing provide better attraction to young people
Poor health and safety conditions in an organization causes gative effect on the choice of career
The essence of career planning is the bridging of individual with organizational goal.

CO2 + H2O → H2CO3. If 495 milliliters of carbon dioxide at 25°C and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid?
Answer:
The theoretical yield of carbonic acid is 1.24 grams.
Explanation:
The balanced equation for the formation of carbonic acid by the reaction of carbon dioxide with water is:
CO₂ + H₂O → H₂CO₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reactant and product participate:
CO₂: 1 moleH₂O: 1 moleH₂CO₃: 1 moleAn ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
Moles of carbon dioxide can be calculated using ideal gas law equation. In this case:
P= 101.3 kPa= 1 atmV= 495 mL= 0.495 L (being 1,000 mL=1 L)n=?R= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= 25 C= 298 K (being 0 C=273 K)Replacing:
1 atm* 0.495 L= n* 0.082 [tex]\frac{atm*L}{mol*K}[/tex] *298 K
Solving:
[tex]n=\frac{1 atm*0.495 L}{0.082\frac{atm*L}{mol*K}*298 K }[/tex]
n= 0.02 moles
Then, by reaction stoichiometry 0.02 moles of carbon dioxide produces 0.02 moles of carbonic acid.
Since the molar mass of carbonic acid is 62.03 g/mol, then you can apply the following rule of three: if there are 62.03 grams in 1 mole, how much mass is there in 0.02 moles?
[tex]mass=\frac{0.02 moles*62.03 grams}{1 mole}[/tex]
mass= 1.24 grams
The theoretical yield of carbonic acid is 1.24 grams.
