Answer:
C7H603 + CH3OH --> C8H803 + H2O
Balanced equation with corresponding stoichiometric numbers.
Explanation:
the salicylic acid, also called aspirin, when reacting with methanol produced an irreversible reaction giving methyl salicylate and water
A higher concentration of reactants leads to more collisions per unit time and leads to an increasing reaction rate. Changing the pressure of gaseous reactants is, in effect, changing their concentration. The increased number of collisions caused by a higher pressure generally increases the reaction rate.
C. Cuz a tornado uses wind so the pressure must be high of it makes thing fly around.
Suppose X (in unit M) be the required maximum concentration of the Pb(NO₃)₂ solution added after mixing with 100 ml of 6.5 x 10⁻² M NaCl, the Pb²⁺ concentration is:
[Pb²⁺] = (X*100) / 200 = 0.5 X
The concentration of Cl⁻ is:
[Cl⁻] = (100 / 200) * (6.5 x 10⁻² M) = 0.0325 M
So:
Ksp = 2.00 x 10⁻⁵ = [Pb²⁺] [Cl⁻]² = (0.5X) * (0.0325)²
X = (2.00 x 10⁻⁵) / (5.28 x 10⁻⁴) = 0.038 M
A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L
B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L
Hoped this helped ( I believe it's right, sorry if it's not )
