The simple answer is no because not all living things have the same amount of energy because they have different properties or functions
Answer:
EVAPORATES IN THE PROCESS OF TRANSPIRATION
Explanation:
Plants takes in water from the soul via it's root system. Small amount of the water are used for growth and metabolism of the plants. Some are used in the process of photosynthesis. The bulk of the remaining are lost through transpiration. This takes place in the stomata of the plants. The stomata are numerous on the leaf surfaces and are guarded by cells which allow for opening and closing of the stomata. Transpiration helps the plants to remove CO2 produced by photosynthesis, cools the plant and also changes osmotic pressure of the plant which allows for the flow of nutrients and water from the root to the leaves, flowers, fruits.
Answer:
28.58 g of NaOH
Explanation:
The question is incomplete. The missing part is:
<em>"Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step"</em>
To do this, we need to know how much of the base we have to weight to prepare this solution.
First we know that is a sodium hydroxide aqueous solution so, this will dissociate in the ions:
NaOH -------> Na⁺ + OH⁻
As NaOH is a strong base, it will dissociate completely in solution, so, starting with the pH we need to calculate the concentration of OH⁻.
This can be done with the following expression:
14 = pH + pOH
and pOH = -log[OH⁻]
So all we have to do is solve for pOH and then, [OH⁻]. To get the pOH:
pOH = 14 - 13.9 = 0.10
[OH⁻] = 10⁽⁻⁰°¹⁰⁾
[OH⁻] = 0.794 M
Now that we have the concentration, let's calculate the moles that needs to be in the 900 mL:
n = M * V
n = 0.794 * 0.9
n = 0.7146 moles
Finally, to get the mass that need to be weighted, we need to molecular mass of NaOH which is 39.997 g/mol so the mass:
m = 39.997 * 0.7146
<h2>
m = 28.58 g</h2>
Answer:
c. 29 J
Explanation:
Step 1: Given data
- Specific heat capacity of Pb (c): 0.13 J/g.K (= 0.13 J/g.°C)
- Initial temperature: 22 °C
Step 2: Calculate the temperature change
ΔT = 37 °C - 22 °C = 15 °C
Step 3: Calculate the heat (Q) required to raise the temperature of the lead piece
We will use the following expression.
Q = c × m × ΔT
Q = 0.13 J/g.°C × 15 g × 15 °C = 29 J
Answer:
to put it simply, equilibrium is when two opposing forces balance each other out. one example is boats: you know how the bottom half is curved, and then meets at an edge? they design it like that because of water displacement. by gravity, the water wants to go back to the area taken by the boats mass (the parts where it has sunken into the water), thus preventing the boat from sinking. once the boat is removed, the water returns to the space. most liquids take form of their container.
