6.9 x 10 to the power of 3 if I am not mistaken.
Answer:
The correct option is: A. H₂SO₄
Explanation:
Acid is a charged or a neutral molecule that is a proton donor and electron pair acceptors.
Acids can be classified into monoprotic acids and polyprotic acids.
Monoprotic acids are the acids that can release only one proton on dissociation.
Whereas, polyprotic acids are the acids that can release more than one proton on dissociation.
Diprotic acid is a type of polyprotic acid that can release two protons on dissociation. Example: H₂SO₄
Answer:
237.5 K.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 5.2 atm).
V is the volume of the gas in L (V = 15.0 L).
n is the no. of moles of the gas in mol (n = 4.0 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = ??? K).
∴ T = PV/nR = (5.2 atm)(15.0 L)/(4.0 mol)(0.0821 L.atm/mol.K) = 237.5 K.
A pH of 7 or lower makes something an acid so it would be 3
The atomic mass is the sum of the protons and neutrons in an atom
