What does the slope of distance vs. time graph show you about the motion graph

1 answer:

3 0

The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object If the velocity is changing, then the slope is changing (i.e., a curved line). If the velocity is positive, then the slope is positive (i.e., moving upwards and to the right).

Convert mass to moles for both reactants. (Round to 2 significant figures.)

shepuryov [24]

Mass = mr x moles
Mr of CuCl2 = ( 63.5) + ( 35.5 x 2) = 134.5
2.5 = 134.5 x moles
2.5 / 134.5 = moles
Moles = 0.019 (2DP)

0.25g of Al
Mr of Al = 27
0.25 = 27 x moles
0.25/ 27 = 0.0093 moles (2sf)

Hope this helps :)

Which of the following is a correct lewis structure for sulfur dioxide, so2?

pshichka [43]

The correct Lewis structure of SO2 is the Lewis structure that shows all the 12 valence electrons in the molecule.

A Lewis structure shows the number of valence electrons on the valence shell of all the atoms in a compound. The electrons are shown as dots around the symbol of each element or a dash to indicate shared electrons in a covalent bond.

Looking at the Lewis structure of SO2 attached to this answer, we can see the twelve valence electrons in the molecule and how they are distributed around each atom as shown.
