Answer:
A. The forces in gases are weaker than forces in solids but stronger
than forces in liquids.
Answer:
I am not quite sure about it, i think it is because of the fact that mercury has weight, when it is filled with mercury, it will expand a little bit.
Answer:
Neutralisation involves an acid reacting with a base or an alkali, forming a salt and water.
Answer:
B; 4 L
Explanation:
From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas
Mathematically, we have this as;
PV = K
Given;
P1 = 2 atm
V1 = 12 l
P2 = 6 atm
V2 = ?
We have that;
P1V1 = P2V2
2 * 12 = 6 * V2
V2 = (2 * 12)/6
V2 = 24/6
V2 = 4 L
Answer:
Concentration of glyceraldehyde-3-phosphate is 0.0886mM
Explanation:
Get K from the expression exp(ΔG/-RT) = K
Where
ΔG = Gibbs free energy = 7.53 kJ/ mol = 7.53 * 10^3 J/mol
T = 250C = 273 +25 = 298 K
R = 8.3145 J(mol.K)
K = exp(7530/(-298*8.3145)
K = 4.79*10^-2
NB: K = (conc of products)/(conc of reactants)
From the question
dihydroxyacetone phosphate is the reactant while glyceraldehyde-3-phosphate is the product
4.70*10^-2 = (conc. Of products/1.85mM)
Conc of products = (4.70*10^-2)*1.85
Conc. Of products = 0.0886mM
