A scientific theory is a principle that can be falsified. The theory has to make strong statements about evidence. If the statements aren't strong, then the theory fits any evidence, and is unfalsifiable.
The formula for ideal gas law is:
P V = n R T
where
P is pressure = ?
V is volume = 1.50 L
n is number of moles = 1.57 mol
R is gas constant = 0.08205746 L atm / mol K
T is temperature = 273 K
P = 1.57 mol * 0.08205746 L atm / mol K * 273 K / 1.50 L
<span>P = 23.45 atm</span>
Answer : The correct option is, D
Explanation :
Saturated solution : It is a chemical solution which contain the maximum amount of solute dissolved in the solvent. In saturated solution, the additional amount of solute will not dissolve in the solvent.
When a student has a solution of sodium nitrate then we can check their saturation point by adding additional amount of sodium nitrate. When we add more amount of sodium nitrate in the solution, then all of it will settle down to the bottom of the container.
Therefore, the best evidence for saturated solution is, When additional sodium nitrate is added, it all settles to the bottom of the container.
Mass divided by volume equals density
The question is incomplete, the complete question is;
The levels of organizations in multicellular organisms are shown below, but they are not in the correct order. Arrange the levels of organization in order from simplest to most complex. tissues organs whole organisms organ systems
Answer:
tissues --> organs --> organ system --> whole organisms
Explanation:
The levels of organizations in multicellular organisms refers to the increasing complexity of the components of the organism.
A tissue is an aggregation of cells hence it is the lowest level of organization here.
Organs are an aggregation of tissues, this is the next higher level of organization.
Organ systems are an aggregation of organs, this is the next higher level of organization.
Whole organisms are an aggregation of organ systems. This is the highest level of organization.
