Answer: it is soluble
Explanation: nitrates are soluble.
This is because copper is a transition metals.
Transition metals don't have a definite charge, you can see this on the periodic table. However, Alkali Earth, Alkali, Metalloids, Non-metals, Halogens, Noble Gases, etc, all have a specified charge.
Although, there are exceptions: Zinc, Gold, and Cadmium.
Aluminum is a poor metal, but it has it's own charge (3+).
Therefore, Copper has roman numerals due to the fact that it's a transition metal and Aluminum is a poor metal.
Hope this helps!
Answer:
a) Step 1:
Step 2:
b) The overall balanced reaction for given process is ;
Explanation:
a)
Galena = 
Lead(II) oxide = 
Sulfur dioxide = 
Step 1:
Roasting the galena in oxygen gas to form lead(II) oxide and sulfur dioxide.
Balanced equation of step 1:
..[1]
Step 2:
Heating the metal oxide with more galena forms the molten metal and more sulfur dioxide.
Balanced equation of step 2:
..[2]
b)
For over all reaction add [1] and [2]. The overall balanced reaction for given process is ;
Answer: C. the blood from carrying oxygen to the tissues of the body.
The carbon monoxide is a poisonous gas, it inhibits the ability of the hemoglobin to distribute oxygen. Hemoglobin is a protein in the red blood cells. The function of the hemoglobin is to distribute oxygen throughout the body. It has high affinity for oxygen. The carbon monoxide replaces oxygen in the hemoglobin. This results in respiratory and cardiac arrest.
