we are asked to multiply 5.4 mm by 6.02 mm
5.4 mm has 2 significant figures
6.02 mm has 3 significant figures
When multiplying these 2 numbers the answer should have the least number of significant figures
From the 2 numbers the least number of significant figures is 2 , therefore answer should be rounded off to 2 significant numbers
5.4 x 6.02 = 32.5 rounded off is 33
Answer is b. 33 m^2
One mole of any element has a mass in grams that is equal to its atomic number, and has exactly 6.02 x 1023 atoms however because the atoms of each element have different sizes and weights, then the volume that each one occupies is different.
Answer:
Your question is not interpreted very well, but as regards what is observed, SO2 is not the formula for sulfur oxide, the formula for sulfur oxide is SO since the valence used in sulfur would be +2 and oxygen -2 therefore the sum of these valences would be equal to zero, therefore it would be the correct thing considering the true equation as SO
Explanation:
There are also sulfur dioxide, or sulfur trioxide, which is usually used in the formation of tertiary salts such as copper sulfate.
sulfur trioxide and sulfur dioxide are synonymous with sulfate or sulphite
In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
