If you are given the number of
moles of sodium bicarbonate, use the balanced chemical equation. The molar mass
of the acetic acid is 60 grams per mole. Using stochiometric balance.
Number of moles of acetic acid =
3 moles NaHCO3 (1 mol CH3COOH/1 mol NaHCO3) = 3 moles of acetic acid
Grams of acetic acid = 3 moles
of CH3COOH (60 g CH3COOH/1 mol CH3COOH) = <span>180 grams of acetic acid</span>

They will have no air and no energy or food. No food for animals, so animals die, and humans die with the lack of food, meat and plants
Answer:
pOH = 5
pH = 9 → Solution is basic
Explanation:
We need to know that:
pH + pOH = 14
< 7 ⇔ pH = 7 ⇔ > 7
Acidic Neutral Basic
pOH = - log [OH⁻] → - log 9.8×10⁻⁶ = 5.00
pOH = 5
pH = 14 - 5 = 9
Answer:
The energy required is 1.634×
J, the wavelength is 1.215×
m, and the kind of electromagnetic radiation is the ultraviolet radiation.
Explanation:
In the question above, the initial level 
= 1, and 
= 2. Then, we use Rydberg's equation to calculate the wavelength of the light absorbed by the atom during the transition.
1/wavelength = R(
)
where:
R is the Rydberg's constant which is equal to 1.0974×
Therefore,
1/wavelength = 1.0974× ×(
) = 1.0974× ×
= (-) 0.8228*10^{7}
Thus,
wavelength = 
= 1.215*
The energy required (E) can be calculated using:
E = h*c/wavelength
where:
h is the Planck's constant = 6.626*
c is the speed of light = 299,792,458 m/s
Therefore,
E = 6.626**299,792,458 m/s÷ 1.215* = 1.634*
The kind of electromagnetic radiation used is is the ultraviolet radiation. This is the type of electromagnetic radiation with wavelength between 10 nm and 400 nm
