Answer:
Explanation:
so u can work out the amount of moles in FeO3 by doing mr of fe3o3 is 55.8*3+16*3=215.4
moles= mass/mr so you do 15.5g/215.4=0.0719 moles
then using 1 to 1 ratio so O2 moles is 0.0719
then use the equation mass=mole*mr
so 0.0719*16=1.15g
hope this make sense :)
the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.
The mass of the acid produced is 0.252 g from the information in the question.
<h3>What is neutralization?</h3>
The term neutralization refers to the reaction between an acid and a base that yileds salt and water only.
The equation of this reaction is; 2HCl + CaCO3 ----->CaCl2 + CO2 + H2O
Number of moles of CaCO3 = 0.350 g/100 g = 0.0035 moles
Since 2 moles of acid reacts with 1 mole of CaCO3
x moles acid reacts with 0.0035 moles of CaCO3
x = 0.007 moles
Mass of acid = 0.007 moles * 36 g/mol = 0.252 g

Answer:
While ionic bonds join metals to nonmetals, and covalent bonds join nonmetals to nonmetals, metallic bonds are responsible for the bonding between metal atoms. In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.
