!!! PLEASE HURRY I HAVE 15 MINUTES Describe the proccess which Mendeleev developed the 1 Periodic Table of the Elements
andrezito [222]

In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.  

i hope this helps in some way!

  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

2.21 × 10²⁴ atoms Al

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

  1. Set up:                              \displaystyle 2.21 \cdot 10^{24} \ atoms \ Al(\frac{1 \ mol \ Al}{6.022 \cdot 10^{23} \ atoms \ Al})
  2. Divide:                              \displaystyle 3.66988 \ mol \ Al

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

Calculate the acceleration of Josh riding his bicycle in a straight line that speeds up from 4 m/s to 6 m/s in 5 seconds. Initia
drek231 [11]

Answer:

Initial Speed ____4m/s. Final Speed ______6m/s. Time ______5 seconds . Acceleration =________0.4m/s²

Explanation:

The acceleration is the rate of change of velocity during time t .

acceleration = Final velocity- Initial velocity/ Time

                    = Vf- Vi/ t

            a = Δv/ Δt

                   = 6m/s- 4m/s/ 5s

                   = 2m/s/ 5s

                  = 0.4m/s²

It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.

If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.
