1) Name: copper(II) nitrate
2) molar mass:
Determine the mass of every element by multiplying its subscript by the atomic mass and add the masses of all the elements
Element atomic mass subscript total mass of the element
Cu 63.55 1 63.55
N 14.01 2 2*14.01 = 28.02
O 16.00 3*2=6 6*16.00 = 96.00
Molar mass = 63.55 + 28.02 + 96.00 = 187.57 g/mol
Answer:
The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).
Explanation:
According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, <em>matter can be neither created nor destroyed</em>. It can only be transformed.
Therefore, in a <u>chemical reaction the atoms are conserved</u>. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and <u>the amount and type of atoms of the products will be the same as the reactants</u>.
In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.
Answer:
i am not 100% shure but the wind speed has little to effect it so a and b are not the answer so i think the answer is D
Explanation:if i got this wrong im sorry it has bin a wile since i answered a question like this.
