I think your answer choices are...
A. an educated guess
B. a statement of pure fact
C. a general principle based on an observable fact
D. a collection of data
Answer:
C. A general principle based on an observable fact
Explanation:
It can't be A as an educated guess is in scientific terms , a hypothesis.
It can't be B as that is a fact or a law
It can't be D as a collection of data is a data table.
Answer:
V₂ = 1.51L
Explanation:
According to Boyle's law:
P₁V₁ = P₂V₂
From the given parameter
P₁ = 153kPa
V₁ = 3.00L
P₂ =304kPa
V₂ = ?
Making V₂ the subject of the formula, we have:
V₂ = P₁ V₁/P₂
V₂ = 153 ₓ 3/304
V₂ = 1.51L
Answer: it goes: collecting data, preforming an investigation, communicating results, asking a question, and then providing an explanation

Hello!
Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.
The scientific notation (N) of 0.000000000333 (x), being (number of decimal places) y, knowing that the scientific notation according to the rule of scientific notation, before the comma can only have the numbers 1 to 9, let's see:
note: Moved 10 decimal places to the right negatively
I Hope this helps, greetings ... DexteR! =)
Answer:
1.Reaction rate is how fast a chemical reaction proceeds.
2.Nature of the reaction, Pressure factor
, Solvent, Catalyst and inhibitors.
3.Physical change is a temporary change. A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc.
4. One example of the effect of temperature is the use of lightsticks or glowsticks.
5.When the particle size of a fixed mass of a solid reactant becomes smaller, the total exposed surface area becomes larger, the rate of reaction increases. an example could be ice and water when the atoms are stuck together a solid but all over the place as a liquid.
6. Sometimes a reaction depends on catalysts to do their job. In that case, changing the concentration of the catalyst can speed up or slow down the reaction. For example, enzymes speed up biological reactions, and their concentration affects the rate of reaction.
7.A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. For example, a catalyst could cause a reaction between reactants to happen at a faster rate or at a lower temperature than would be possible without the catalyst.
