Answer:
8.8 cm³
Explanation:
Data given:
volume of Liquid = 0.0088 L
convert volume to Cubic centimeters
Solution:
There are number of unit in which volume can be measured
As
Liter is unit of volume represented by L
Cubic centimeters represented by cm³
liter is larger value then cm³
Now to convert L to cm³
As we Know
1 L = 1000 cm³
So
Apply unity formula
1 L = 1000 cm³
0.0088 L = x cm³
Do Cross multiplication
x cm³ = 0.0088 L x 1000 cm³ / 1 L
x cm³ = 8.8 L.cm³ / 1 L
x cm³ = 8.8 cm³
So,
0.0088 L of liquid = 8.8 cm³
Answer:
Explanation:
The model written correctly is:
This is a mathematical question, instead of a chemistry question, and you should use calculus to find the nitrogen level that gives the best yield, since this is an optimization problem.
The best yield is the maximum yield, and the maximum, provided that it exists, is found using the first derivative and making it equal to zero: Y' = 0
To find Y' you must use the quotient rule.
Now make Y' = 0
- The denominator is never equal to zero, because it is always positive and greater than 9.
- Make the numerator equal to zero:
9k - kN² = 0
- Since k is a positve constant, it is not equal to zero, and the other factor, 9 - N², must be equal to zero:
9 - N² = 0 ⇒ (3 - N) (3 + N) = 0
⇒ 3 - N = 0 or 3 + N = 0 ⇒ N = 3 or N = -3.
Since N is nitrogen level, it cannot be negative and the only valid answer is N = 3.
You can prove that it is a maximum (instead of a minimum) finding the second derivative or testing some points around 3 (e.g. 2.5 and 3.5).
Pollution because it’s one of the reasons for global warming, and global warming causes habitat destruction causing many organisms to become extinct
Answer:
1+1=2 Unless this is a trick question. Then it's most likely 11.

Answer:
Formula weight of H₂O molecule is 18.02 amu.
Explanation:
Given data:
Formula weight of H₂O = ?
Atomic mass of H = 1.008 amu
Atomic mass of O = 16.00 amu
Solution:
Formula weight:
"It is the sum of all the atomic weight of atoms present in given formula"
Formula weight of H₂O = 2×1.008 amu + 1×16.00 amu
Formula weight of H₂O = 18.02 amu
Thus, formula weight of H₂O molecule is 18.02 amu.
