3. What is the total pressure of a mixture of nitrogen and hydrogen, in atm, if the
partial pressure of nitrogen is 509.7 mmHg and the partial pressure of hydrogen is
630.3 mmHg?
Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So, P=P_H+P_N+P_WP=P

A 20. 0-liter flask contains a mixture of argon at 0. 72 atmosphere and oxygen at 1. 65 atmospheres. What is the total pressure in the flask? A. 0. 93 atm B. 2. 37 atm C. 8. 44 atm D. 18. 6 atm.
The total pressure of the system is equivalent to the sum of all the pressure of the individual gases. The total pressure of the flask is 2.37 atm.
What is total pressure?According to Dalton's law, the total pressure of the system will be equivalent to the total of the pressures exerted by the individual gases present in the system.
The total pressure of gases is given as,
[tex]\rm P = P_{1} +P_{2}+ P_{3}.....P_{n}[/tex]
Given,
The pressure of argon gas = 0.72 atmThe pressure of oxygen = 1.65 atmTotal pressure = PSubstituting values in the above equation:
[tex]\begin{aligned}\rm P &= 0.72 + 1.65\\\\&=2.37\;\rm atm\end{aligned}[/tex]
Therefore, 2.37 atm is the total pressure of the flask.

Answer:Conduction transfers heat between two materials that are touching, such as foil and chocolate pieces, or particles, such as the atoms in foil.Convection allows heat to be transferred in liquids, like water.Radiation transfers heat from a light bulb to paper.Conduction,
convection, and radiation move energy from the Sun to Earth and throughout Earth.
Explanation:
Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object.
Convection: This is a transfer of heat by mixing a fluid.
Radiation is the transfer of heat in wave form.
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.

What is the mass of cs present in 15. 0 g of cesium acetate, formula csch3coo?.
Answer:
the answer is ''4g''
Explanation:
The mass of Cs present in 15.0 g of caesium acetate is approximately 10.18 grams.
To calculate the mass of Cs (caesium) present in 15.0 g of caesium acetate ([tex]\rm CsCH_3COO[/tex]), you need to determine the molar mass of [tex]\rm CsCH_3COO[/tex] and then find the proportion of Cs in the formula.
Molar mass of [tex]\rm CsCH_3COO[/tex]:
Cs: 1 atom * atomic mass of Cs = 1 * 132.91 g/mol = 132.91 g/mol
C: 2 atoms * atomic mass of C = 2 * 12.01 g/mol = 24.02 g/mol
H: 6 atoms * atomic mass of H = 6 * 1.01 g/mol = 6.06 g/mol
O: 2 atoms * atomic mass of O = 2 * 16.00 g/mol = 32.00 g/mol
Total molar mass of [tex]\rm CsCH_3COO[/tex] = 132.91 + 24.02 + 6.06 + 32.00 = 194.99 g/mol
Now, find the proportion of Cs in the formula:
Mass of Cs in 1 mol of [tex]\rm CsCH_3COO[/tex] = 132.91 g/mol
Mass of Cs in 15.0 g of [tex]\rm CsCH_3COO[/tex] = (15.0 g * 132.91 g/mol) / 194.99 g/mol ≈ 10.18 g
Thus, the mass of Cs present in 15.0 g of caesium acetate is approximately 10.18 grams.

Answer the questions using complete sentences.
1.What is the difference in electron movement between ionic and covalent bonding?
2.How can you predict if a bond would be ionic or covalent based on the location of the elements on the periodic table?
3.How could you predict if a bond would be ionic or covalent based on electronegativity?
4.What has to happen in order for bonds to break in reactants?
5.How does the height of an object affect the amount of gravitational potential energy it has?
6.What is kinetic energy?
7.What is the connection between kinetic energy and temperature? If the temperature goes up, what happens to the KE?
Answer/Explanation:
[1] The difference in electron movement between ionic and covalent bonding is ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms.
[2] One way you can predict if a bond would be ionic or covalent based on the location of the elements on the periodic table is to look how far apart the two atoms forming the bonds are in the periodic table. If one atom is on the far left (Group 1 or 2) and the other is on the far right (Group 5, 6, or 7), then the atoms will have large differences in EN and will form an ionic bond.
[3] You can predict if a bond would be ionic or covalent based on electronegativity is If the electronegativity difference is less than 0.5, then the bond is nonpolar covalent. If the ΔEN is between 1.6 and 2.0 and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.
[4] In Order for bonds to break in reactants Molecules must collide in order to react. In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds.
[5] The height of an object affect the amount of gravitational potential energy it has by gravitational potential energy (P.E) depends on the mass of the body and the height at which it travels, the two quantities will therefore dictate the work done on the object which is eventually the same as magnitude of the gravitational potential energy P.E. It is assumed that gravitational pull acts toward the earth surface. The more the object move upward the more the work is done on the object to pull it down. We can have different masses of object at different heights, but gravitational field strength will always remain constant on earth.Since the gravitational potential energy P.E depend on the mass of the body and the height at which it travels, the two quantities will therefore dictate the work done on the object which is eventually the same as magnitude of the gravitational potential energy P.E.
[6] Kinetic energy is a form of energy that an object or a particle has by reason of its motion.Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
[7] The connection between kinetic energy and temperature is the relationship between temperature and kinetic energy is that the higher the temperature, the more kinetic energy there is. As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container.

For the cell notation shown, which species is undergoing reduction?
For the cell notation shown, [tex]Ag(s)[/tex] is the species that is undergoing reduction.
What is reduction?Reduction can be defined as a chemical reaction or phenomenon through which the number of electrons or oxidation states associated with the atoms of a chemical element are changed.
This ultimately implies that, reduction is a half-reaction that typically involves decreasing the oxidation number of a chemical species, especially by gaining electrons.
In this scenario, [tex]Ag(s)[/tex] is the species that is undergoing reduction because it is not oxidized and it gains one (1) electron.
