Answer:

d = 3 g/cm³

Explanation:

Given data:

Mass of stone = 27 g

Volume of water = 10 cm³

Volume of water+ stone = 19 cm³

Volume of stone = ?

Density of stone = ?

Solution:

Volume of stone = total volume - volume of water

Volume of stone = 19 cm³ -  10 cm³

Volume of stone = 9 cm³

Density of stone:

d = m/v

d = 27 g/ 9 cm³

d = 3 g/cm³

An atom emits a photon with energy 7.13 electronvolts (eV). What is the wavelength of the photon?
sergey [27]

Answer:

Option (b) "174 nm"

Explanation:

Energy of emitted photon is 7.13 eV.

We need to find the wavelength of the photon.

1 eV = 1.6 × 10⁻¹⁹ J

Energy of a photon is given by :

E=\dfrac{hc}{\lambda}

Where, \lambda is wavelength of the photon

Putting all the values,

\lambda=\dfrac{hc}{E}\\\\\lambda=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{7.13\times 1.6\times 10^{-19}}\\\\\lambda=1.74\times 10^{-7}\ m\\\\\text{or}\\\\\lambda=174\ nm

So, the wavelength of the photon is 174 nm.

Using the following combustion reaction, describe how it follows the laws of conservation of mass and energy. CH 4 +2O 2 CO 2 +2
AURORKA [14]

Answer:

Explanation:

The law of conservation of mass states that "mass in a system remains constant and that the mass of the product is remains the same as that of the reactants".

Law of conservation of energy states that "energy is neither created nor destroyed in the course of chemical or physical change but can be transformed from one form to another".

 Let us properly write the equation:

               CH₄ + 2O₂ → CO₂ + 2H₂O

For the conservation of mass:

  C has 1mole on both sides

   H has 4mole on both sides

   O has 4 mole on both sides

For energy, during combustion process, the methane CH₄ burns to liberate heat energy. This is an energy conversion process in which chemical energy in methane releases heat energy.

If the solubility of a gas in water is 1.22g/2.75 atm, what is it’s solubility (in g/L) at 1.0 atm
Slav-nsk [51]

Answer : The solubility of a gas in water at 1 atm pressure is, 0.4436 g/L

Solution : Given,

Solubility of a gas in water = 1.22 g/L     (at 2.75 atm pressure)

At pressure = 1 atm,     Solubility of a gas = ?

Now we have to calculate the solubility of a gas.

At 2.75 atm pressure, the solubility of a gas in water = 1.22 g/L

At 1 atm pressure, the solubility of a gas in water = \frac{1atm}{2.75atm}\times 1.22g/L=0.4436g/L

Therefore, the solubility of a gas in water at 1 atm pressure is, 0.4436 g/L
