How it total reaction energy calculated ?

Physics
1 answer:
larisa [96]3 years ago
4 0

Here, we are required to determine how the total reaction energy is calculated.

Total reaction energy =

  • Energy of the product - Energy of the reactants.

The total reaction energy, otherwise known as the Enthalpy of the reaction is given by the difference between the enthalpy of the product and that of the reactants.

Also, it is important to note that the enthalpy is the sum total of the internal energy and the work energy of the entity in discuss, which may either be the reactants or the products.

Ultimately,

Total reaction energy =

  • Energy of the product - Energy of the reactants.

The escape speed from the moon is much smaller than from earth. True or False
Lisa [10]

Answer:

True

The escape speed from the Moon is much smaller than from Earth.

Explanation:

The escape speed is defined as:

v_{e} = \sqrt{\frac{2GM}{r}}  (1)

Where G is the gravitational constant, M is the mass and r is the radius.

The mass of the Earth is 5.972x10^{24}kg and its radius is 6371000m

Then, replacing those values in equation 1 it is gotten.

v_{e} = \sqrt{\frac{(2)(6.67x10^{-11}N.m^{2}/kg^{2})(5.972x10^{24}kg)}{(6371000m)}}  

v_{e} = 11.18m/s

For the case of the Moon:

v_{e} = \sqrt{\frac{(2)(6.67x10^{-11}N.m^{2}/kg^{2})(7.347x10^{22}Kg)}{(1737000m)}}  

v_{e} = 2.38m/s

Hence, the escape speed from the Moon is much smaller than from Earth.

Since it has a smaller mass and smaller radius compared to that from the Earth.

How many kj of heat are needed to completely melt 144 g of titanium metal, given that the metal is at its melting point? the hea
Elina [12.6K]

Given, mass of titanium metal = 144 g

Heat of fusion of titanium metal= 18.7 J/g

Heat of fusion is the amount of heat energy needed to change the state of one gram of a substance from solid to liquid or vice-versa.

Thus, 18.7 J of heat is needed to melt one gram of titanium metal.

Therefore, heat needed to melt 144 g of titanium metal = 18.7×144

= 2692.8 J

What height would a 4 kg book need to be to have a potential energy of
zloy xaker [14]

Answer:

5.99 m  = 6 m

Explanation:

PE = m*g*h

235.2 J = (4 kg)(9.81 m/s^2)(h)

h = (235.2 J)/(9.81*4)

h = 5.99 m

h = 6 m

12. Which of the following is a true statement regarding electrical drawings?
horsena [70]

The statement which is true regarding electrical drawings is; Choice A: Dimensions and distances matter greatly on blueprints but not on schematics.

<h3>Difference between a schematic diagram and a blueprint</h3>

The major difference between a schematic diagram and a blueprint lies in the fact that blueprint means a type of paper-based reproduction process producing white-on-blue images, used primarily for technical and architecture's drawings, now largely replaced by other technologies, whereas schematic diagrams are simplified line-drawing generally used by engineers and technicians to describe and understand how a system works at an abstract level.

Ultimately, Dimensions and distances matter greatly on blueprints but not on schematics.
