Answer:
To the right.
Explanation:
The chemical equilibrium is a state of a reactant system in which they are not observed changes as time goes by, even though the reaction continues. In other words, the chemical equilibrium is established when there are two opposite reactions which take place simultaneously at the same speed.
The variation in the concentration of any of the species involved in the equilibrium varies the value of the concentrations of the remaining species in the equilibrium.
In this case the concentration of one of the reaction reagents varies, increasing it since there is a greater amount of CO. This causes the balance to change to the products to compensate for the reaction. Then the balance goes to the right.
Answer:
Explanation:
by using litmus papaer it will turn into red if solutions is acidic
and into blue if it's basic
by using Magnesium ribbon. Magnesium do not react with bases so hydrogen gas will produce when Magnesium is dipped in an acidic solution
Answer:
1 being or located on the outside; external
2 further from the middle or central part
Explanation:
Answer:
ΔH = +26.08 kJ/mol
Explanation:
The change in enthalpy (ΔH) is given in J/mol, and can be calculated for dissolution by the equation:
ΔH = m(water)*Cp*ΔT/n(solute)
The mass of water is the density multiplied by the volume
m = 1g/mL * 25.0mL = 25.0 g
The number of the moles is the mass divided by the molar mass. Knowing the molar masses of the elements:
N = 14 g/mol x 2 = 28
H = 1 g/mol x 4 = 4
O = 16 g/mol x 3 = 48
NH₄NO₃ = 80 g/mol
n = 1.25/80 = 0.015625 mol
So,
ΔH = 25*4.18*(25.8 - 21.9)/0.015625
ΔH = 26,083.2 J/mol
ΔH = +26.08 kJ/mol
