There are three broad types of nonexperimental research. Single-variable research focuses on a single variable rather than a relationship between variables. Correlational and quasi-experimentalresearch focus on a statistical relationship but lack manipulation or random assignment.
It is called situational irony. An example would<span> be when someone buys a gun to protect himself, but the same gun is used by another individual to injure him.</span>
Answer:
A theory is more than simply an idea because the idea itself forms the hypothesis that in turn is used as the context for the experiments, tests, and gathering evidence that will go to prove or disprove the initial hypothesis. A theory then is the positive benefits of proof and evidence and is the proven outcome of the subject of the hypothesis.
Explanation:
<span>There are approximately 10 decigrams per each gram, so that means in 100 grams there are exactly 1,000 decigrams. I came to the conclusion that the hamster weighs 1,000 decigrams, and if the hamster eats all 200 decigrams he will weigh approximately 1200 decigrams.</span>
Answer:
Explanation:
In a chemical reaction, the order of reaction with respect to one species is the exponent of the species in the rate law.
The experimental <em>rate law of the reaction</em> is:
![rate=k[H_3AsO_4]\cdot [I^-]\cdot[H_3O^+]](https://tex.z-dn.net/?f=rate%3Dk%5BH_3AsO_4%5D%5Ccdot%20%5BI%5E-%5D%5Ccdot%5BH_3O%5E%2B%5D)
That means:
-
![[H_3AsO_4]](https://tex.z-dn.net/?f=%5BH_3AsO_4%5D)
, ![[I^-]](https://tex.z-dn.net/?f=%5BI%5E-%5D)
, and ![[H_3O^+]](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D)
are the concentrations of the reactants
- The exponents are 1, 1, and 1.
- Thus, the order of the reaction with respect to each species is 1.
- The overall order is the sum of the exponents: 1 + 1 + 1 = 3.
In conclusion, <em>the order of reaction with respect to </em><em> is 1.</em>
