Answer:
pH = 4.34
Explanation:
pH= -1/2(logKa) -1/2(log C)
= -1/2( log 5.98*10^-8) -1/2(log 0.0353)
=-1/2(-7.22)-1/2(-1.45)
=3.61+0.725= 4.34
The cars are hanging from cables so that there is presence of more medium of propagation to make it look real.
<h3>What is a Blast wave?</h3>
This is referred to as a violent propagating disturbance, produced by an explosion in air.
Hanging the cars in the air will ensure an accurate description of the effect of the blast wave on them.

Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:

Relation of
with
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles =
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
Answer:
the rock layers of the Grand Canyon
Explanation:
Steno's law are laws that applied to sedimentary rocks. These laws helps in understanding sedimentary sequences.
Sedimentary rocks are derived from the deposition of pre-existing rocks in basins. In order to understand some important relationships between these rock layers, Steno's law offer a good insight.
Steno's law are often applied when we want to do relative dating of rock layers. Some of the laws are:
- Law of superposition of strata
- Law of original horizontality
- Law of lateral continuity
- Law of inclusion
- Law of fossil and fauna succession
These laws helps to interpret sedimentary rock sequences better.
