Answer:
The heat released by the combustion is 20,47 kJ
Explanation:
Bomb calorimeter is an instrument used to measure the heat of a reaction. The formula is:
Q = C×m×ΔT + Cc×ΔT
Where:
Q is the heat released
C is specific heat of water (4,186kJ/kg°C)
m is mass of water (1,00kg)
ΔT is temperature change (23,65°C - 20,45°C)
And Cc is heat capacity of the calorimeter (2,21kJ/°C)
Replacing these values the heat released by the combustion is:
<em>Q = 20,47 kJ</em>
Answer:
The characteristic best supports its formation from sedimentary processes is "It has many layers."
Explanation:
When sediments deposit and solidifies then it results in the formation of sedimentary rocks.The given picture shows that this rock has many horizontal lines of different width and color. This shows that this rock is formed by many different layers. Thus, we can conclude that the characteristic which best supports its formation from sedimentary processes is that it has many layers. The layers present gives us an idea about the past events that has occurred for the formation of the or the deposition of the sedimentary rock.
Answer:
The answer is
<h3>6000 N/m² or 6000 Pa</h3>
Explanation:
The pressure exerted by an object given the force of the object and the area can be found by using the formula

where
P is the pressure
f is the force
a is the area
From the question
f = 2400 N
a = 0.4 m²
So we have

We have the final answer as
<h3>6000 N/m² or 6000 Pa</h3>

Answer : The volume of water added are, 15 mL
Explanation :
Formula used :

where,
are the initial molarity and volume of HCl.
are the final molarity and volume of water.
We are given:

Putting values in above equation, we get:

Hence, the volume of water added are, 15 mL
