1.Calculate the number of mole of O2: 48/32=1.5 mol
2.Calculate the number of mole of H2 by mole ratio: 1.5 x 1/2=0.75 mol
3.Calculate the answer:
0.75 x 2=1.5g
The answer is C. Thank you
Explanation:
La identidad de un átomo y sus propiedades vienen dadas por el número de partículas que contiene. Lo que distingue a unos elementos químicos de otros es el número de protones que tienen sus átomos en el núcleo. Este número se llama Número atómico y se representa con la letra Z.
Answer:Water is attracted to the sodium chloride crystal because water is polar and has both a positive and a negative end. The positively charged sodium ions in the crystal attract the oxygen end of the water molecules because they are partially negative.
Some physical properties of the compound are related in this way.
Molecular mass of the compound, depends on the atomic masses of the elements.
Wether the compound is ionic or covalent depends on the nature of the bonds which depends on the electronic configuration of the elements.
Boiling pont depends, solubility, melting point and others depend on the strength of the bonds, wich depends on the electronic configuration of the elements.
So many other properties also are determined by the properties of the elements and the bonding of them to form the compound.
Solubility of the compound depends on
