Answer:
ways it rust are
1.you put water on it
2.let it sit out side for about a month or 2
or
you put the iron in water still wait a month or 2 then
you got the full or sum rusty parts
Explanation:
ether way you need water, air ,and the main thing... IRON
the balanced chemical equation representing the reaction between represent sodium metal (Na) and chlorine gas (cl2) is as below
2 Na + Cl2→ 2 NaCl
2 moles of sodium metal ( Na) reacted with 1 mole of gas chlorine gas (cl2) and 2 moles of sodium chloride (NaCl)
Answer is: 1 × 10⁻¹⁰ meter or 0.0000000001 meter.
The atomic radius is a measure of the size of the atom.
It is distance from the center of the nucleus of atom to the boundary of electron cloud.
The radius of atoms is between 30 and 300 pm (10⁻¹² m) or between 0.3 and 3 angstroms (10⁻¹⁰ m).
The radius generally decrease along each period of the Periodic table.
To determine the limiting reactant, we first calculate the number of moles of the reactant.
7.00 g H2 ( 1 mol / 2.02 g ) = 3.47 mol H2
70.00 g N2 ( 1 mol / 28.02 g) = 2.50 mol N2
From the balanced reaction, we see that there is a 3 is to 1 ratio of the reactants. So, for every 3 moles of H2 we need 1 mole of N2. Given the amount of reactant, for 2.50 moles of N2 we need 7.5 moles of H2 which obviously we have a lesser amount. Hydrogen is the limiting reactant.
I believe the answer is false. It is not safe <span>to heat flammable liquids with a bunsen burner even when it’s done in a fume hood. It is never recommendable to heat liquids that are flammable since it has a very high risk. Hope this answers the question.</span>
