By placing the steel wool in a jar with plenty of oxygen and water, you start a chemical reaction. The iron and the oxygen react to form a new reddish-brown substance, called iron oxide or rust.
Explanation:
one thing to know is that higher surface area = higher boiling point.
NaCl has the smallest surface area, so it's the first one.
H2O has less surface area than methane, so it's second.
Methane has more surface area than H20, so it's third.
The big molecule has the most surface area, so it's last
Answer:
one would be if the human had no say in it
Answer:
Number of moles = 2 mol
Explanation:
Given data:
Mass of carbon = 24 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of carbon is 12 g/mol.
Now we will put the values in formula.
Number of moles = 24 g/ 12 g/mol
Number of moles = 2 mol
Answer:
received energy from water
