Mg + HCI + H2 + MgCl2 Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
Solid magnesium reacts with aqueous hydrochloric acid producing aqueous
magnesium chloride and hydrogen gas bubbles.
Describe what would happen to the reaction if you increase the
concentration of the hydrochloric acid. Why would this happen (include
the collision theory in your response)?
• Describe what would happen to the reaction if you decrease the
concentration of the hydrochloric acid. Why would this happen (include
the collision theory in your response)?
Make your own analogy regarding concentration and rates of reaction to a
real life situation.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

hloride, what is the mass of calcium in

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
