please don't forget to give me some help on the math qestion that i ask if do you not any think , thanks
Answer:buckled railroad tracks on a hot day
Explanation: i just did it
Answer: The given statement is true.
Explanation:
Boiling point is defined as the point at which vapor pressure of a substance becomes equal to atmospheric pressure. During this point, the liquid changes into vapor state and temperature remains constant till all the liquid changes into vapor state.
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
Thus, we can conclude that the statement if the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil, is true.
Answer:
HI& HNO3= strong acid
H2CO3 &HF= weak acid
LiOH & Ba(OH)2= strong base
CH3NH2= weak base
NH4Cl = weak acid solution
Na3PO4 = weak base solution
Explanation:
HI& HNO3= strong acid because they can dissociate completely producing free Oxonium ions
H2CO3 &HF= weak acid because there dissociate partly in Solution
LiOH & Ba(OH)2= strong base because LiOH is a group one alkali which dissociate completely and Ba(OH)2 a group 2 alkali which dissociate completely as well
CH3NH2= weak base because in solution it dissociates partly forming NH4+ ion
NH4Cl = weak acid solution because it is a salt of strong acid and weak base
Na3PO4 = weak base solution
Because it's a salt of strong base and weak acid
<span>The ionisation eq for MNCO3 is given by
MnCO3 --> Mn^2+ + CO3^2-
Recall Ksp=[Mn^2+][CO3^2-]
From the chemical reaction one moles of manganese and carbon reacts
Here molar solubility of MnCO3 is 4.2 * 10^-6 M;
Which means that when 4.2 * 10^-6 moles of [Mn^2+] reacts, it also reacts with 4.2 x 10^-6 M of CO3
Thus Ksp= 4.2 x 10^(-6) x 4.2 x 10^(-6) = 17.64 * 10^(-6+(-6)) = 17.64 * 10^(-12)</span>
