Determine the number of atoms in the following chemical formulas. Make sure you list the elements, how many atoms of each element, and how many total atoms. Numbers 1 and 6 have been completed as examples. 8NaCl = 8+8=16 (To find the total number of atoms add the total number of atoms)
Na=1x8=8 (remember to multiply the subscript by the coefficient)
Cl=1x8=8

Explanation:

In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound.

For an example, let's look at the the formula for compound glucose:

C 6  H 12  O 6

The subscripts that follow each element's symbol indicate how many of that element are in the compound.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
