Answer:
A), C), and E)
Explanation:
We need to use the Le Chatelier´s principle to answer this question as follows:
A) Increasing the size of the reaction vessel has the effect of decreasing pressure, so the equilibrium will shif to the side that has greater pressure which in this case is the products, so we the number of moles of CS2 will increase.
B) If we add more product Cl2 to the system it will shift to the reactants to counteract the change in the equilibrium; therefore, some CS2 will be consumed.
C) If we add reactant S2Cl2 to the system it will shift to the product side therby increasing the number of moles of CS2
D) The reaction is endothermic so it will shift to the reactant side.
E) Adding more reactant CCl4 will shift the equilibrium to the right side favoring more CS2
Answer:
1.55 × 10²⁵ atoms of H
Explanation:
3.21mol C₃H₈ × 8mol H × (6.022×10²³)
Answer:
D.the wavelength of a wave is the distance between two successive peaks or two successive troughs or a peak and trough
Answer:
Explanation:
Hello!
In this case, since the molar mass of the empirical formula is:
Thus, the ratio of the molecular to the empirical formula is:
Thus, the molecular formula is six times the empirical formula:
Best regards!
Mols CuSO4 = M x L = 1.50 x 0.150 = 0.225
<span>mols KOH = 3.00 x 0.150 = 0.450 </span>
<span>specific heat solns = specific heat H2O = 4.18 J/K*C </span>
<span>CuSO4 + 2KOH = Cu(OH)2 + 2H2O </span>
<span>q = mass solutions x specific heat solns x (Tfinal-Tinitial) + Ccal*deltat T </span>
<span>q = 300g x 4.18 x (31.3-25.2) + 24.2*(31.3-25.2) </span>
