The period of an osciller is 2.34 minutes. What id the frequency of this oscillator in hertz?
AleksAgata [21]

Explanation:

Given parameters

Period = 2.34minutes

Unknown:

Frequency of the oscillator = ?

Solution:

Frequency is the number of waves that passes through a point at a given time. It is the inverse of period which is the time it takes for a wave to pass through a medium:

             F = \frac{1}{T}

F is the frequency

T is the period

      To solve this, convert the period to seconds:

              2.34minutes to seconds:

                1 min = 60seconds

              2.34 =  60 x 2.34 = 140.4s

F = \frac{1}{140.4} = 0.007hz or 0.007s⁻¹

If 4.9 kg of CO2 are produced during a combustion reaction, how many molecules of CO2 would be produced?
solmaris [256]

Answer:

6.7 x 10²⁶molecules

Explanation:

Given parameters

Mass of CO₂  = 4.9kg  = 4900g

Unknown:

Number of molecules  = ?

Solution:

To find the number of molecules, we need to find the number of moles first.

 Number of moles  = \frac{mass}{molar mass}

          Molar mass of CO₂  = 12 + 2(16)  = 44g/mol

   Number of moles  = \frac{4900}{44}  = 111.36mole

A mole of substance is the quantity of substance that contains the avogadro's number of particles.

       1 mole  = 6.02 x 10²³molecules

     111.36 moles  =   111.36 x 6.02 x 10²³molecules   = 6.7 x 10²⁶molecules

Explain why raising the temperature of a liquid would speed up diffusion
nikitadnepr [17]
Because diffusion<span> is the process when molecules move to lower or higher concentration, so as the molecules move faster they are going to lower or high concentration faster.</span>
