Answer:
Box #1: a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Explanation:
The terms: The scientific method describes the processes by which scientists gain knowledge about the world. It's characterized by six key elements: questions, hypotheses, experiments, observations, analyses, and conclusions. These elements are interrelated steps, so they don't always function in the same order.
The Relation: When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
Answer:
Particles in a solid object are super tight and close to eachother. They do not move past eachother because it is a solid, not a liquid or gas.
Explanation:
Both the acid and the base are known as strong substances which means they totally dissociate into ions in aqueous solution. Mixing the two a salt would be form which is NaNO3. The unreacted substances will be the one contributing to the pH of the solution.
0.125M HNO3 x 0.04L = 0.005 mol HNO3
<span>0.125M NaOH x 0.05L = 0.00625 mol NaOH
</span>
As we can see, all of the HNO3 would react with NaOH so the remaining OH from the unreacted NaOH would be responsible for the pH.
0.00625 - 0.005 / ( 0.0500L + 0.0400L ) = 0.0139 M
<span>pOH = -log( OH- ) </span>
<span>pOH = 1.86 </span>
<span>pH = 14.00 - pOH </span>
<span>pH = 12.14</span>
By using the quantum model of the atom and John Dalton's model you can predict that the methane molecule will most likely be made up of Hydrogen and Carbon.
Answer:
Aquatic ecosystem has two components -
- Biotic components
2.Abiotic components
temperature and amount of sunlight are the part of abiotic component .
while living things like sponges and planktons are the biotic components of ecosystem.
Explanation:
aquatic components are of two types-
freshwater ecosystem( lakes and ponds, river and streams)
marine ecosystem(ocean ecosysyem, estuaries)
planktons-
planktons are found in limnetic zone, availability of sunlight is much here. planktons are zooplanktons and phytoplanktons are very important link in aquatic ecosystem.
sponges
In marine water, the <em>benthic zone</em> is the area below the<em> pelagic zone.</em> Here temperature decreased because of less light perception. This zone is very nutrient rich so organisms which are present here are- bacteria, fungi, sea anemone, sponges and some fishes.
