When making a guess, you are forming a hypothesis.
A hypothesis is a statement you make based on your observations of a certain phenomenon, so it's an educated guess.
You will then carry out an experiment whose results will hopefully support your hypothesis.
Explanation:
Hypothesis is a supposition or projected clarification created on the premise of restricted proof as a place to begin for more investigation.A hypothesis may be a tentative, testable answer to a scientific question. Once a person encompasses a scientific question she is fascinated by, the person reads up to search out out what's already far-famed on the subject. Then she uses that data to make a tentative answer to her scientific question. Typically folks discuss with the tentative answer as "an educated guess."
Answer:
ΔH = 5102.88 KJ/mol
Explanation:
- Qp = ΔH = CpΔT... constant pressure
∴ Cp = 2.48 KJ/°C
∴ ΔT = 0.400°C
∴ Mw C8H18(g) = 114.22 g/mol
∴ mol C8H18(g) = (0.0222 g)×(mol C8H18/114.22 g) = 1.944 E-4 mol C8H18
⇒ ΔH = (2.48 KJ/°C)×(0.400°C) = 0.992 KJ
⇒ ΔH = 0.992 KJ/ 1.944 E-4 mol C8H18
⇒ ΔH = 5102.88 KJ/mol
Gas and radio waves I’m pretty sure is correct
The statement which correctly describe the relationship between the reactants and the yield is this: 'the theoretical yield is calculated from the amount of the limiting reactants present'. The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed.
