Chemistry
1 answer:
garri49 [273]3 years ago
8 0
(d) Density of Benzene: 0.8786 g/cm cubed
(m) Mass: 20.00g
Formula to solve (v) volume of benzene: V=m/d
V=20g / 0.8786g/cm cubed
Answer: Volume of benzene is: 22.8 cm cubed  
<span>
Explanation: Well, density is mass divided volume. In this, it is what the volume is. All you need is mass divided by density. Hope this helps!</span>

A bell hanging at the top of a tower has 8,550 j of energy. If it has a mass of 20 kg find the height of the Bell
kogti [31]

43.62m

Explanation:

Given parameters:

Energy = 8550J

Mass of bell = 20kg

Unknown:

Height of the bell = ?

Solution:

As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

  Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity of the body

h is the height of the body

The unknown is h and we should solve for it.

  g = 9.8m/s²

     Input the variables;

        8550 = 20  x  9.8 x h

     h = 43.62m

Describe the relationship between"q" and energy in the melting of an ice cube.
klio [65]

Answer:

Now "q" is  the heat and energy is the capacity of any object or body ton perform any work. So we can relate them if we take the term specific heat in consideration.

As specific heat is the the amount of heat required to raise the temperature of an object in specific from one degree Celsius, for ice it is 2.108 kJ/kgK.

Explanation:

  • c = specific heat capacity,

  • q = heat

  • ΔT = change in temperature

So, we have:

  • C= Q/ΔT
  • It is the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object.

Yield for this reaction?<br> Reaction: N2(g) + 3 H2(g) → 2 NH3 (g)
andriy [413]

Answer:

Yes, yield.

Explanation:

N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation

First, find limiting reactant:  

Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2

Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2

The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)

Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3
