Trisha and her lab partner were conducting a variety of experiments to produce gases: hydrogen, oxygen, and carbon dioxide. in one experiment, they added a piece of magnesium ribbon to 10 milliliters of hydrochloric acid. they observed bubbles being produced and did a variety of tests to identify the escaping gas; it proved to be hydrogen the reaction is represented by the following equation: mg + 2hcl → mgcl2 + h2(g) trisha and her lab partner filled a beaker with 150 milliliters of a 0.10 m hcl solution. how many moles of hcl are in the beaker? remember, molarity = moles liter . a) 0.015 mol hcl b) 0.150 mol hcl c) 6.67 mol hcl d) 15 mol hcl

Given:

Volume of HCl = 150 ml

Molarity of HCl = 0.10 M

To determine:

The # moles of HCl

Explanation:

The molarity of a solution is the number of moles of a solute dissolved in a given volume

In this case:

Molarity of HCl = moles of HCl/volume of the solution

moles of HCl = Molarity * volume = 0.10 moles.L-1 * 0.150 L = 0.015 moles

Ans: A)

Moles of HCl is 0.015

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

the answer is b & c i believe : )
