The answer would be C. CH3COOH, deprotonated
Answer:
The correct answer is 0.75 atm
Explanation:
We have carbon monoxide gas (CO) at the following conditions:
T= 30ºC = 303 K
V= 20.0 L
m = 17 g
The molecular weight of CO (MM CO) is the following:
MM CO= molar mass of C + molar mass of O = 12 g/mol + 16 g/mol = 28 g/mol
We calculate the number of moles (n) as follows:
n= m/MM CO = 17 g/28 g/mol = 0.61 mol
Finally we use the ideal gases equation to calculate the pressure (P):
P x V = n x R x T
P = (n x R x T)/V
P= (0.61 mol x 0.082 L.atm/K.mol x 303 K)/20.0 L
P= 0.75 atm
Answer:
a
Explanation:
most of the world is made of water because the oceans.
Acid-base conjugate pair forms when the element donates a proton and another species acquires it. and are the base-conjugate acid pair.
<h3>What is base-conjugate acid pair?</h3>
Acids are the species or element and compounds that donates proton or hydrogen ions to form a conjugate base.
Bases are the elements or compounds that acquires protons or hydrogen ions and form a conjugate acid pair.
Conjugate acids and bases are the species or the products formed when the protons or hydrogen ions are increased or decreased in their chemical structures.
The reaction can be shown as,
From the reaction, it can be said that the water molecule acquired the hydrogen or the proton ions and the hydronium ion produced as a result is the conjugate acid of the water base.
Therefore, and are the base-conjugate acid pair.

Volume of 3M solution: x
Moles in 3M solution: 3x
C = n/V
1,8 = 3x/0,05dm³
0,09 = 3x
x = 0,03dm³
A student need 0,03dm³ 3M HCl and 0,02dm³ of water.
