Answer:
A. 0.1828 g/cm³
Explanation:
Hi there,
Density's well known formula is Greek letter rho: ρ 
where m is the mass, and V is volume. Since the volume in question is a cube, the volume of a cube is simply the edge length 
³
³ = 68.921 cm³
ρ 
= 0.1828 g/cm³
Thanks,
Explanation:
Kp remains constant (if T=const.).
If Q<Kp, more reactants are consumed (the direct reaction is in progress). If Q>Kp the reverse reaction is in progress (the products are consumed).
1. A reaction will occur in which PCl5 (g) is consumed
A. If Kp > Qp then 1,2,3 and 5 are F. 4 is T
B. Kc > Qc then 1,3 are T. 2,4,5 are F.
C. Qp > Kp then 1.3.4 are T. 2,5 are F.
Answer:
The correct answer is - 4-nitroaniline.
Explanation:
It is given that all three solid compounds salicylic acid + 4-nitroaniline + naphthalene are equal in the ratio in the mixture and then 1 gram of this mixture is dissolved in the diethyl ether and run a drop of the solution on TLC plate. This plate shows three spots.
The salicylic acid and naphthalene would stay dissolved in the diethyl ether solution due to the 4-nitroaniline could be extracted by adding aqueous acid and involve in the aqueous layer and thus spot of 4-nitroaniline would be with largest Rf value.
Protons and neutrons are located in the nucleus of the atom. Electrons are located in the electron cloud outside/around the nucleus. Protons have a positive charge, neutrons have a neutral charge, or no charge, and electrons have a negative charge
