The chemical composition of the magma and the rate at which it cools determine what rock forms. Igneous rocks can cool slowly beneath the surface or rapidly at the surface. These rocks are identified by their composition and texture.
Hope this help XD
Answer;
it combines with the water and H in the atmosphere and creates sulfuric acid thus making the rain acidic
Explanation:
Yes, nitrogen is a non metal!
Explanation:
Silver nitrate + iron (III) chloride --> silver chloride + iron (III) nitrate
The balanced chemical equation is given as;
2FeCl3 + 3Pb(NO3)2 → 2Fe(NO3)3 + 3PbCl2
Mass of Pb(NO3)2 = 25g
How many grams of iron (III) nitrate were formed?
From the equation;
3 mol of Pb(NO3)2 produces 2 mol of Fe(NO3)3
Converting to mass using;
Mass = Number of moles * Molar mass
Pb(NO3)2;
Mass = 3 mol * 331.2 g/mol
Mass = 993.6 g
Fe(NO3)3;
Mass = 2 mol * 241.86 g/mol
Mass = 483.72 g
This means 993.6 g produces 483.72 g
We have;
993.6 g = 483.72 g
25 g = x
solving for x;
x = 25 * 483.72 / 993.6
x = 12.1709 g of iron (III) nitrate
Answer:
The answer is
<h2>0.32 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass = 6.05 g
volume = 19 mL
The density of the substance is
We have the final answer as
<h3>0.32 g/mL</h3>
