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.

a hiker in africa discovers a skull that contains 43% of its original amount of c-14 Find the age of the skull to the nearest ye
11Alexandr11 [23.1K]
The amount of C-14 at time t is
N(t) = N_{0} e^{-Kt}
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴

When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
e^{-10^{-4}t} = 0.43 \\\\ -10^{-4} t = ln(0.43) \\\\ t = - \frac{ln(0.43)}{10^{-4}} =8439.7 \, years

Answer:
The age of the skull s 8440 years (nearest integer)

A 25 N force pushes a block across a surface for 6 m.How much work is done by the applied force?
hram777 [196]

Answer: 150 joules

Explanation:

Force applied on a block = 25N

Distance moved by block = 6 m

Workdone = ?

Recall that work is done when force is applied on an object over a distance. And it is measured in joules.

I.e Workdone = Force X Distance

= 25N x 6 metres

= 150 joules

Thus, 150 joules of work is done by the applied force.
