Answer: hydrogen
All acids have the hydrogen ion in common
Explanation:
According to Arrhenius theory, an acid is a substance which dissociate in water to produce hydrogen ions, H+;
For example: HCl --> H+ + Cl-
while a base is a substance which gives hydroxide ions, OH-, in water
For example: NaOH(s) --> Na+(aq) + OH-(aq)
Thus, all acids have the hydrogen ion in common
Answer:
.0388 atm
Explanation:
Since temperature is not given , we assume that it is constant . So we can apply Boyle's law . According to it
P₁ V₁ = P₂ V₂
P₁ and V₁ are pressure and temperature initially and P₂ and V₂ are pressure and volume finally .
Putting the given values
.12 x 2.31 = 7.14 x P₂
P₂ = .12 x 2.31 / 7.14
= .0388 atm .
Answer:
Balanced chemical equation:
C₃H₈ + 5O₂ → 4H₂O + 3CO₂
Explanation:
Chemical equation:
C₃H₈ + O₂ → H₂O + CO₂
Balanced chemical equation:
C₃H₈ + 5O₂ → 4H₂O + 3CO₂
1st step:
Left side Right side
C = 3 C = 1
H = 8 H = 2
O = 2 O = 3
2nd step:
C₃H₈ + O₂ → H₂O + 3CO₂
Left side Right side
C = 3 C = 1×3 = 3
H = 8 H = 2
O = 2 O = 6+1 = 7
3rd step:
C₃H₈ + O₂ → 4H₂O + 3CO₂
Left side Right side
C = 3 C = 1×3 = 3
H = 8 H = 2×4 = 8
O = 2 O = 6+4 = 10
4th step:
C₃H₈ + 5O₂ → 4H₂O + 3CO₂
Left side Right side
C = 3 C = 1×3 = 3
H = 8 H = 2×4 = 8
O = 2×5= 10 O = 6+4 = 10
The chemical formula for this is KNO₃ (that small number is a 3)
hope this helps and if it needs to be broken down further then let me know :)
