Answer:
The group one element are called alkali because when they dissolved in water they form alkaline solutions
At STP, 1 mole of an ideal gas occupies a volume of about 22.4 L. So if <em>n</em> is the number of moles of this gas, then
<em>n</em> / (19.2 L) = (1 mole) / (22.4 L) ==> <em>n</em> = (19.2 L•mole) / (22.4 L) ≈ 0.857 mol
If the sample has a mass of 12.0 g, then its molecular weight is
(12.0 g) / <em>n</em> ≈ 14.0 g/mol
Answer: A 'rogue wave' is large, unexpected, and dangerous.
At the time, surface winds were light at 15 knots. ... Most reports of extreme storm waves say they look like "walls of water." They are often steep-sided with unusually deep troughs.
Explanation:
V = fλ
3 x 10⁸ = f x 6.5 x 10⁻⁷
f(red) = 4.6 x 10¹⁴ Hz
The frequency of the second wave is higher, meaning it has a lower wavelength and greater energy than that of red light.
