The atoms of a substance can be determined by dividing the given mass of the substance by the molar mass. This results to moles of the substance. Then we multiply by the Avogadro's number. In this case, we divide 1 g by 58. 69 g/ mol and multiply by 6.022 x10^23 atoms / mole. The answer is 1.03 x10^22 atoms
Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
![HBr+Mg(OH)_2\rightarrow MgBr_2+H_2O](https://tex.z-dn.net/?f=HBr%2BMg%28OH%29_2%5Crightarrow%20MgBr_2%2BH_2O)
However, it need to be balanced since two bromine atoms are produced, therefore we write:
![2HBr+Mg(OH)_2\rightarrow MgBr_2+2H_2O](https://tex.z-dn.net/?f=2HBr%2BMg%28OH%29_2%5Crightarrow%20MgBr_2%2B2H_2O)
Thus, the products are magnesium bromide, MgBr2, and water, H2O.
Best regards!
Answer:
particle size, shape, color, and magnetic attraction.
Explanation:
6H, 3S, and 12O
6 + 3 + 12 = 21
I believe 21 is your answer. I may be wrong, but I hope this helps anyways!
Answer:
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.
