Answer:
Percent yield = 75%
Explanation:
Given data:
Actual yield of ammonia = 60 g
Theoretical yield of ammonia = 80 g
Percent yield = ?
Solution:
Percent yield is calculated dividing the actual yield by theoretical yield and multiply by 100.
Formula:
Percent yield = Actual yield / Theoretical yield × 100
Now we will put the values in formula.
Percent yield = 60 g/ 80 g × 100
Percent yield = 0.75 × 100
Percent yield = 75%
So if the reaction yield is 60 g and calculated yield ( theoretical yield) is 80 g then the percent yield would be 75%.
Answer is: Increased pressure would increase the rate of forming water vapor.
According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products (water waper) of chemical reaction increase, if:
1) decrease temperature, because this is exothermic reaction (ΔH is negative).
2) increase concentration of reactants (oxygen and hydrogen).
3) increase pressure of the system, so reaction moves to direction where is less molecules.
Answer:
2200J
Explanation:
Given parameters:
Specific heat of aluminum = 0.88J/g°C
Mass of nugget = 50g
Initial temperature = 20°C
Final temperature = 70°C
Unknown:
Quantity of heat required for the heating = ?
Solution:
To solve this problem, we use the expression below;
H = m c Δt
H is the quantity of heat
m is the mass
c is the specific heat capacity
Δt is the change in temperature
H = 50 x 0.88 x (70 - 20) = 2200J
Its unstable and flammable... the Hindenberg used it... we saw how that went
