223.44 grams is the answer. Multiply 2.28 times the gram formula mass of h2so4
Answer:
Explanation:
endergonic
A chemical reaction that has a positive ΔG is correctly described as A) endergonic.
Answer:
it contains 2.56 x 10^15.
Explanation:
given no. of moles = 4.26 x 10^-9 atoms
one mole has 6.022 x 10^23 atoms
so it contains 4.26 x 10^-9 x 6.022 x 10^23 atoms
(If we suppose silver's atomic weight as 108.)
1,4,5 in that order couse the hypothensis is what I believe in. It should not be hard to find my control conditions after that. I will also then relate it to my hypothensis and say why it is correct or why the experiment proved my hypothensis wrong.
<u>Given:</u>
Frequency (ν) = 319 THz
<u>To determine:</u>
The wavelength corresponding to the given frequency
<u>Explanation:</u>
Wavelength (λ) and Frequency(ν) are related as:
λ = c/ν
where c = speed of light = 3*10⁸ m/s
Now:
SI unit of frequency is Hertz (Hz) also expressed as cycles per second
i.e 1 Hz = 1 s⁻¹
1 Terahertz (THz) = 10¹² Hz
therefore the given frequency ν = 319 *10¹² s⁻¹
λ = 3 * 10⁸ ms⁻¹/319 *10¹² s⁻¹ = 940 * 10⁻⁹ m
since 1 nanometer (nm) = 10⁻⁹ m
The wavelength is λ = 940 nm
Ans: The infrared wavelength = 940 nm
