Now that you have performed this lab experiment see how well you know the procedures order. put the steps below in the order they must be performed by numbering them 1-7. Use a bunsen burner to he enjoy the hydrate repeating until the mass no longer decreases

Measure the final masses of the crucible cover and Anhydrous salt

compute differences in masses to find the reactants and products

Measure initial masses in the crucible and cover with and without the hydrate

use the numbers of most to compare the mole ratio

use stoichiometry to convert these masses to moles

use the mole ratio to write the hydrates formula

What is conserved in the reaction shown below? h2(g) + cl2 (g) --> 2hcl(g)a. mass onlyb. mass and moles onlyc. mass, moles, and molecules onlyd. mass, moles, molecules, and volume

8. what happens to matter during a chemical reaction

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
