Answer:
The density of gas is 0.2 Kg / L.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
mass = 0,6 Kg
volume= 3 L
density = ?
Now we will put the values in the formula,
d= m/v
d = 0.6 Kg / 3L
d = 0.2 Kg / L
The density of gas is 0.2 Kg / L.
Answer:
Explanation:
The addition of AgNO3 to the system Cl⁻ react with result into the formation a precipitate of AgNO3, as such the reactant concentration decreases.
Suppose the concentration of a given substance is present in an equilibrium system is changed without a change in any of the other conditions, then, by le chatelier's principle, the position of equilibrium will move to decrease the concentration of the added substances. In order to relieve this constraint, the equilibrium will shift to the right favouring the forward reaction.
According to Boyle's Law,
" the volume of a fixed mass of gas is inversely proportional to the pressure applied on it'.
Mathmatically,
V ∞ 1 / P
Or,
V = k / P
Explanation:
The balloon filled with Neon gas outside the chamber will have greater volume than in the chamber because the pressure in the chamber is high as compared to outside. So, the outside force brings the molecule of gas to get closer to each other.
Sodium metal reacts rapidly with water to form a solution of sodium hydroxide (NaOH) and hydrogen gas (H2). This reaction is exothermic.
Equation:
2Na + 2H²0 --------}- 2NaOH + H²
Answer:
Nanomachines will work with atoms, not nuclei. The smallest unit of a chemical element, about a third of a nanometer in diameter. Atoms make up molecules and solid objects.
