Answer: remove toxins from the body
Explanation: think of it. When you are sick you throw up. When you eat too much food you throw up
The question needs:
In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...
H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄
H₂O is most
second N₂H₄
N₂H₅ and OH⁻ present in equal amount
H₃O⁺ is zero
because N₂H₄ is weak base it partially ionizes in water as following:
N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
Answer:
450.0 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
<em></em>
V₁ = 760.0 L, P₁ = 450.0 mm Hg,
V₂ = ??? L, P₂ = 760.0 mm Hg (standard pressure = 1.0 atm = 760 mm Hg).
∴ V₂ = (P₁V₁)/(P₂) = (760.0 L)(450.0 mm Hg)/(760.0 mm Hg) = 450.0 L.
It absorbs heat and give off thermal energy just saying i think its right
The light reflected from the surface of the Moon takes only a second to reach Earth. The Sun is more than 8 light-minutes away. And so, if the light from the nearest star (Alpha Centauri) takes more than 4 years to reach us, we're seeing that star 4 years in the past.
