Answer:
<u>True</u>
Explanation:
|ndeed, Psychologist Abraham Maslow's sought to describe hierarchy in which the average (or most) humans place their needs. In other words, he believes we as humans have basic needs which we long to satisfy.
On the ranking or hierarchy, according to Maslow the need humans satisfy first is their physiological need. Here's the full hierarchy:
Physiological Needs
↓
Safety Needs
↓
Love/Belonging Needs
↓
Esteem Needs
↓
Self-Actualization

Answer:
The yearly release of 
into the atmosphere is 
.
Explanation:
Annual production of CaO = 
Moles of CaO :
According to reaction, 1 mole of CaO is produced along with 1 mole of carbon-dioxide.
Then along with 
of CaO moles of carbon-dioxide moles produced will be:
of carbon-dioxide
Mass of 
moles of carbon-dioxide:
The yearly release of into the atmosphere is .
Answer:
Explanation:
Given parameters :
Volume of solution = 100mL
Absorbance of solution = 0.30
Unknown:
Concentration of CuSO₄ in the solution = ?
Solution:
There is relationship between the absorbance and concentration of a solution. They are directly proportional to one another.
A graph of absorbance against concentration gives a value of 0.15M at an absorbance of 0.30.
The concentration is 0.15M
Also, we can use: Beer-Lambert's law;
A = ε mC l
where εm is the molar extinction coefficient
C is the concentration
l is the path length
Since the εm is not given and assuming path length is 1;
Then we solve for the concentration.
