Answer: 0.0450 moles of 
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
Thus there are 0.0450 moles of
Answer:
Energy produced by the chip =10,460 Joules.
Explanation:
The specific heat of water is one calorie/gram ° C = 4.186 joules/gram ° C, which is higher than any other common substance. As a result, water plays a very important role in regulating temperature. The specific heat per gram for water is much greater than that of a metal, as described in the water-metal example. Replace the mass (m), the temperature change (ΔT), and the specific heat (c) of the solution in the equation Q = c x m x ΔT, where Q is the heat absorbed by the solution. For specific heat of water we goes as given in the question 4,184 J/kg°C
Q =4184×0.5×(25-20)
=10,460 Joules.
Thus heat gained by water (Q)= Energy produced by the chip =10,460 Joules.
Answer:
Uhhhh I think this is it
Explanation:
Some changes to total pressure, like adding an inert gas that is not part of the equilibrium, will change the total pressure but not the partial pressures of the gases in the equilibrium constant expression. Thus, addition of a gas not involved in the equilibrium will not perturb the equilibrium.
Answer:
Kp = P(SO2) * P(O2) / P(SO3)
Explanation:
The equation is given as;
SO3(g) --> SO2(g) + O2(g)
In the pressurer equilibrium constant expression, only the gaseous entities are considered.
It is given as;
Kp = P(products) / P(reactants)
Product are SO2(g) and O2(g)
Reactant is SO3(g)
Kp = P(SO2) * P(O2) / P(SO3)
