Answer:

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.

ionic compounds are electrically neutral overall. therefore, the sum of the charges on the cation and anion in each formula unit must be equal to zero

Ions are charged particles that form when an atom (or group of atoms) receives or loses an electron, and ionic compounds are composed of these charged particles. An anion is a negatively charged ion, whereas a cation is a positively charged ion.

Answer:

There are 5.69*10²⁴ molecules in 9.45 moles.

Explanation:

The mole is defined as the amount of matter that particles have, that is, atoms and elementary entities.

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

Then the following rule of three can be applied: if 1 mole contains 6.023 * 10²³ molecules, 9.45 moles, how many molecules will it have?

[tex]amount of molecules=\frac{9.45 moles*6.023*10^{23}molecules }{1 mole}[/tex]

Solving:

amount of molecules= 5.69*10²⁴⁴ molecules

There are 5.69*10²⁴ molecules in 9.45 moles.

Answer:

Molar mass = 105 g/mol

Explanation:

Given data:

Mass of gas = 3.15 g

Pressure = 785 mmHg

Temperature = 20°C

Volume of gas = 750 mL

Molar mass of gas = ?

Solution:

Pressure = 785 mmHg (785/760 = 1 atm)

Temperature = 20°C (20+273 = 293 K)

Volume of gas = 750 mL (750 mL× 1 L/1000 mL = 0.75 L)

PV = nRT

R = general gas constant (0.0821 atm.L/mol.K)

1 atm× 0.75 L =  n×0.0821 atm.L/mol.K × 293 K)

0.75 atm.L = n× 24.06 atm.L/mol

n = 0.75 atm.L / 24.06 atm.L/mol

n = 0.03 mol

Molar mass of gas:

Molar mass = Mass / number of moles

Molar mass = 3.15 g/ 0.03 mol

Molar mass = 105 g/mol

The major difference between heat transfer by conduction and convection and heat transfer by radiation is that heat transfer by conduction and radiation requires a material medium, while heat transfer by radiation is done by electromagnetic waves and doesn't require a medium.

Heat or thermal energy is the energy generated when atoms or molecules move in a variety of directions (translational, rotational and vibrational). The three methods of heat transfer are convection, conduction and radiation. Conduction only occurs between solid objects in contact, convection occurs within a fluid, and radiation occurs through electromagnetic waves.

Unlike conduction and convection, radiation doesn't require a material medium before heat is transferred, as electromagnetic radiations don't require a material medium to propagate. Heat is transferred by radiation through infrared rays. Other differences include:

Maximum wavelength of light capable of dissociating the f-f bond is 7.6245 nm.

Wavelength related to bond dissociation energy is calculated by first calculating the energy required to break one f-f bond which is calculated as,

energy required to break a bond=bond energy/Avogadro's number

In this case which is equal to,157×10³/6.022×10²³=2.6071×10[tex]^-19[/tex] J.

Now to calculate wavelength, Planck's equation is used which is,

E=hc/λ

∴λ=6.626×10[tex]^-34[/tex]×3×10⁸/2.6071×10[tex]^-19[/tex]

=7.6245×10[tex]^-7[/tex] m or 7.6245 nm
