Image result for How do we determine how many orbitals to draw?
An s orbital is a sphere. In two dimensions, we draw it as a circle.
...
One orbital looks like a p orbital with two doughnuts around its middle.
Two orbitals have eight lobes pointing towards the corners of a cube.
Four orbitals have six lobes oriented in various planes (e
The element strontium (atomic number = 38) has four naturally-occurring isotopes. They are: Isotope / Percent Abundance / Mass (amu) Sr-84 / 0.56% / 83.9134 Sr-86 / 9.86% / 85.9093 Sr-87 / 7.00% / 86.9089 Sr-88 / 82.58% / 87.9056 The first thing to do is to convert all of the percentages to decimal fractions. To do that just move the decimal point two places to the left. Be careful, though...if the decimal is already at the front of the number you STILL have to move it two places. Add leading zeroes as necessary. 0.56% becomes 0.0056 9.86% becomes 0.0986 7.00% becomes 0.0700 82.58% becomes 0.8258 Next multiply each of the decimal fractions by the mass of each isotope. 0.0056 x 83.9134 = 0.47 0.0986 x 85.9093 = 8.47 0.0700 x 86.9089 = 6.08 0.8258 x 87.9056 = 72.59 Finally add the results to find the average atomic mass. 0.47 + 8.47 + 6.08 + 72.59 = 87.61 amu This agrees closely with the listed atomic mass for strontium, so I know I probably did my work correctly. I hope that helps
Answer:
Las sales ideales para la saponificacion es la combinacion de grasas complejas con muchas cadenas de trigliceridos y de la soda caustia.
Explanation:
Un ejemplo de estos son la grasa vacuna o la aceite de cocina de consumo tradicional y la soda caustica que es el hidroxido de sodio.
Juntos estos dos productos forman el proceso de saponificacion.
