A straight chain hydrocarbon with the formula C5 H10: has a double C-C bond
C. HNO₃(aq) + KOH(aq) → KNO₃(aq) + H₂O
Answer:A) It was developed from past observations- true
It is subject to experimentation and revision.- false
It explains why mass is conserved- false
It predicts future observations-true
Explanation:
Before a hypothesis is proclaimed to be a law in science, numerous observation must have confirmed its validity and rigorous experimentation under carefully controlled conditions usually precedes the acceptance of a hypothesis as a law. The law of conservation of mass was developed from numerous past observation that proved its validity.
Answer:
The wavelength is the distance from the peak of one wave to the peak of the next.
Explanation:
The wavelength of UV light ranges from 10 nm to 400 nm.
We can’t see UV light because our eyes can detect only light with wavelengths between 400 nm (violet) and 700 nm (red).
