Answer:
C₆H₈O₆
Explanation:
The molecular formula of given compound is C₆H₈O₆. Because there are six carbon, six oxygen and eight hydrogen atom present in this compound.
The molecular weight of following compound is,
C₆H₈O₆
C = 12 amu
H = 1 amu
O = 16 amu
C₆H₈O₆ = 12×6 + 1×8 + 16×6
C₆H₈O₆ = 72 +8 + 96
C₆H₈O₆ = 176 g/mol
Answer:
c) acidic
Explanation:
pKa is a value which describes the acidity of a solution. The solution is pKa ≤ 25 which means that the solution is more acidic. The lower value of pKa tells us that the solution is more acidic but when the pKa value of solution increases the acidity of the solution is also decreases. Due to lower value of pKa, the acid in the solution is fully dissociates in water.-5 to 50 is the range of the value of pKa for different solutions.
The mass of the air sample is calculated using the below
Q(heat)=M(mass) x C(specific heat capacity) x delta T(change in temperature)
Q= 120.j
M=?
C= 1.0j/g/c
delta T =45.0-33.2=11.8 c
by making M the subject of the formula
M=Q/C delta T
= 120 j/ 1.0 j/g/c x11.8 c=10.17 grams
Answer:
Uranium can be isolated from its ores by dissolving it as UO 2(NO3)2, then separating it as solid UO2(C2O4)∙3H2O.
