Define atomic numbers and mass numbers

Answers

Atomic numbers is the number of a chemical element in the periodic table and the mass number is the total number of protons and neutrons in an atom

Answer:

1). Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

2) In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes.

3) Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

HELP PLEASE ILL GIVE OUT BRAINLIEST

Answers

A) tides and waves.

The phenomena which  wind causes  are waves and surface currents.

What are surface  currents?

Surface currents are caused by  winds  which blow over the ocean water and result in creation of waves. Surface currents  are horizontal streams of water which are capable of  flowing thousands of kilometers and can reach great depths.

Surface currents play a major role in determining the climate all over the world. They are influenced by three major factors 1) overall global wind patterns 2)rotation of earth 3)shape of ocean basins . When a surface  current collides with the land it  changes the direction of currents.

Because of surface currents the global climate has warmer water  from equator to the cooler parts of the ocean  as they transfer heat energy.

describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).

Answers

Answer:

Molecules don’t have to collide with each other in order to experience intermolecular forces.

Molecules with permanent dipoles, held in fixed orientation, such as water molecules in the solid state (ice), interact with a potential proportional to the inverse cube of distance. This intermolecular force always exists, no matter how far apart the molecules are; every water molecule interacts with every other water molecule. However, because it diminishes rapidly with distance, it tends to only be important at short distances. (In contrast, the potential between two ions goes as 1/r, and that between an ion and a dipole goes as 1/r^2.)

The van der Waals forces, of which London dispersion forces are the most important, are described by a potential proportional to the inverse sixth power of distance. Theoretically, those forces are always operating between any two atoms or molecules, but again, only become important at short distances.

Octane has a density of 0.703 g/ml. Calculate the mass of CO2(g) produced by burning one
gallon of octane. There are 3.79 liters to one gallon.

Answers

The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

The given parameters:

Density of the octane, ρ = 0.703 g/mlVolume of octane, v = 3.79 liters

The mass of the octane burnt is calculated as follows;

[tex]m = \rho V\\\\m = 0.703 \ \frac{g}{ml} \times 3.79 \ L \ \frac{1000 \ ml}{L} \\\\m = 2,664.37 \ g[/tex]

The combustion reaction of octane is given as;

[tex]2C_8H_{18} + \ 25O_2 \ --> \ 16CO_2 \ + \ 18H_2O[/tex]

From the reaction above:

228.46 g of octane -------------------> 704 g of  CO₂ gas

2,664.37 of octane --------------------> ? of CO₂ gas

[tex]= \frac{2,664.37 \times 704}{228.46} \\\\= 8,210.3 \ g\\\\= 8.21 \ kg[/tex]

Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

If the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture in a buret

Answers

Answer:

f the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture

Partial pressure of H2 in gas mixture is :

739.765 torr .

Explain total pressure?The overall pressure ptot is the total of all pressures in a reference system. This pressure, according to Bernoulli (see Fluid mechanics), consists of the static pressure p, the dynamic pressure pdyn, and the geodetic component ( g z) that exists in a fluid along a stream line in a frictionless flow.The total pressure of a gas mixture is the sum of its component gases' partial pressures: Ptot = ∑Pi = P1 + P2 + P3... ntot = total number of moles in the gas mixture (the sum of all ni).

Total  pressure of mixture =

Partial of hydrogen + Partial pressure of oxygen

Partial of Hydrogen = Total pressure - partial   pressure  of  oxygen

Here total pressure = 757.3 torr

Partial pressure of oxygen = 17 . 535 torr

Total pressure = 757 . 3 - 17 . 533

                        = 739.765 torr.
