Answer:
the answer would be C of not C is B
The rock is limestone, I hope this helps!!
You have to use Dalton's law of partial pressure for this question. Dalton's law of partial pressure basically states that the total pressure of the system is all of the partial pressures of the components added together. Therefore to answer the question you just need to add all the patial pressures together meaning that the total pressure would be 700+500+500=1700.
The answer would be 1700 torr.
I hope this helps. Let me know if anything is unclear or if you have any further questions.
I attached the working and the answer to the question below.
Please note that C = speed of light, ν = frequency, λ= wavelength
<span> The wavelength of a 2.80 Hz wave is
1.07 </span>
× 10¹⁰
Independent variable: calculators, computers
Dependent variable: speed
3 constants: seat, atmospheric condition, and time.
Control: none
<h3>What are variables</h3>
Variables are of different types in experiments. They can be:
- Independent: a variable that is supplied by the researcher and which can be tweaked among different experimental groups to produce different outcomes.
- Dependent: variables whose value is dependent on the kind of independent variable supplied by the researcher. It is the actual variable that is measured during the course of experiments.
- Constant: all other variables that are kept the same among experimental groups.
Thus, in this case, the independent variable will be the calculator or computer/calculator combination given to the two groups.
The dependent variable will be the speed at which each group finished solving the math problems.
The constant variable will be all other variables supplied to the two groups.
