Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Frequency = 1290 kHz = (As 1 kHz = 1000 Hz )
Thus, Wavelength is:
Answer:
22
Explanation:
5.5 mol C3H8 • (4 mol H2O / 1 mol C3H8 ) = 22 mol H2O
Answer:
Saturation.
Explanation:
Hello,
In this case, the statement is accounting for the saturation vapor pressure as it is the pressure of a vapor which is in equilibrium with its liquid, in other words it is the maximum exerted pressure possible by the vapor at a given temperature or just the maximum amount of the vapor, so there is neither no more vapor that could condense nor more liquid that could boil.
Best regards.
Answer:
3−
Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.
Explanation:
The number of significant figures within a number are the amount digits that are required to specify a number to a certain degree of accuracy. In the number, 0.0645 g, the 6 is the most significant figure and 4 is the second most significant figure. Therefore, rounding to two significant figures yields 0.064g.
