Answer:
A violent reaction will occur and zinc sulphide is formed as a product
Answer:
= 18.75 L
Explanation:
Using the combined gas law;
P1V1/T2=P2V2/T2
Where; P1 is the initial pressure, 0.25 atm
V1 is the initial volume 300.0 L
T1 is the initial temperature, 400 K
P2 is 2 atm and
T2 is 200 K
Therefore;
(0.25 × 300)/400 = 2V2/200
V2 = (75 ×200)/(400×2)
= 18.75 L
Answer:
The object is moving at a constant speed.
Answer:
61.4 %
Explanation:
Let's consider a generic chemical reaction.
Reactants ⇒ Products
The theoretical yield is the maximum mass of product that theoretically can be obtained from the chemical reaction.
The actual yield is the mass of the product obtained from the reaction.
The percent yield is:
Percent yield = actual yield / theoretical yield × 100%
Percent yield = 60.9 g / 99.2 g × 100% = 61.4 %
