Hypothesis: When zinc is added to copper
sulfate, a single displacement reaction will take place, creating a solid, copper, and zinc sulfate.
hope i didnt misunderstand the question
Answer:
Copper is a reddish-brown metal that is easily stretched to make wires. These characteristics are examples of Dhybral (physical/chemical) properties of copper.
Explanation:
When copper metal is heated in concentrated nitric acid, the copper dissolves to form a deep blue solution, and a brown gas is released from the acid.
True!
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.
Answer: The partial pressure of oxygen in the mixture if the total pressure is 525 mmHg is 310 mm Hg
Explanation:
mass of nitrogen = 37.8 g
mass of oxygen = (100-37.8) g = 62.2 g
Using the equation given by Raoult's law, we get:
= partial pressure of = ?
= total pressure of mixture = 525 mmHg
Total moles = 1.94 + 1.35 = 3.29 moles
Thus the partial pressure of oxygen in the mixture if the total pressure is 525 mmHg is 310 mm Hg
