Boron trifluoride is the correct name for compound BF3
Answer:
La masa atómica del hierro es 55.847 gramos por mol.
Explanation:
Las masas molares de
,
,
y
son 53.940 gramos por mol, 55.935 gramos por mol, 56.935 gramos por mol y 57.933 gramos por mol, respectivamente. La masa atómica del hierro se determina mediante el siguiente promedio ponderado:

La masa atómica del hierro es 55.847 gramos por mol.
The gradient is the slope of a linear equation, represented in the simplest form as y = mx + b. In Earth Science, the gradient is usually used to measure how steep certain changes in elevation are.
In order to find the gradient in a topographical setting, one must know two things: the elevation of two points and the distance between the two points. Once these values are known, the gradient can be found by dividing the change in field value, or the change in elevation, by the distance. The higher the gradient value is, the steeper the slope is.
you calculate all the letters together and it would be Zn2
