Answer:
A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.
Explanation:
The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.
Answer:
Every single celled organism is able to survive because it carries out metabolic activities.
Metabolic activity is a set of chemical reactions which are needed for an organism to maintain it's life
Explanation:
the various types of metabolic processes keep an organism alive. There are various types of metabolic processes that takes place in the body of living organism.
These are cellular respiration, reproduction, excretion, digestion et cetera. Every living cell has these processes going on in their body to keep them alive.
Living organism need energy to carry out these processes which they get by eating food.

The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is 2.08 atm.
<h3>What is the pressure?</h3>
In this problem, we are mandated to obtain the pressure both by the use of the ideal gas equation and then the use of the Van der Walls equation.
Using the idea gas equation;
PV = nRT
P = nRT/V
P = pressure
V = volume
n = number of moles
T = temperature
R = gas constant
P = 1 * 0.082 * (24 + 273)/0.5
P = 48.7 atm
Using the Van Der Wall equation:
P = RT/(V - b) - a /V^2
P = 0.082 * 297/(0.5 - 0.03219) - 1.345/(0.5)^2
P = 24.354/0.46781 - 1.345/ /0.25
P = 52 - 5.38
P = 46.62 atm
The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is; 48.7 atm - 46.62 atm = 2.08 atm

Answer:
<h2>406 K</h2>
Explanation:
To convert a temperature from degree Celsius to Kelvin add 273 to the value in degree Celsius
That's
K = 273 + °C
where
K is the temperature in Kelvin
°C is the temperature in degree Celsius
From the question we have
K = 273 + 133
We have the final answer as
<h3>406 K</h3>

Answer:
0.591 g of magnesium phosphate is the theoretical yield.
Magnesium nitrate is the limiting reactant.
Explanation:
Hello!
In this case, since the balanced reaction turns out:
Next, we compute the grams of magnesium phosphate yielded by each reactant, considering the present mole ratios and molar masses:
Thus, we infer that the correct theoretical yielded mass is 0.591 g as magnesium nitrate is the limiting reactant for which it produces the fewest grams of product.
However, is not possible to compute the percent yield since no actual yield is given, and must be provided or indicated by the problem or an experiment and it not here, nevertheless, you may compute the percent yield by dividing the actual yield by the theoretical and then multiplying by 100:
Best regards!
