Answer:

Moles of HCl is 0.015.

Explanation:

Molarity of HCl = 0.10 M

Volume of HCl = 150 mL

Conversion factor for mL to L is,

1\ mL = 10^{-3}\ L

So, 150 mL = 0.15 L

Molarity is given by,

Molarity=\frac{Moles}{Volume\ in\ L} \\Moles = Molarity \times Volume\ in\ L

Substitute values in the above formula

Moles = 0.10 \times 0.15\\=0.015\ mol

Moles of HCl is 0.015.

M=mol/liter
We know that we have 150ml=.15 L and .1 mol of HCl
Rearranging the molarity equation, we get
mol=M*l
mol=(.15)(.1)
=.015 mol

Dovator [93]

Answer:

Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first. These organisms help enrich the soil, allowing other species to become established.

Image result for think about succession and the places you have seen or visited. choose one place, provide evidence from your experience, to determine whether your example showed primary or secondary succession. you can write and/or include pictures

For example, after a forest fire that kills all the mature trees on a particular landscape, grasses might grow, followed by shrubs and a variety of tree species, until eventually the community that existed before the fire is present again

What is redox reaction??<br><img src="https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20" id="TexFormula1" title=" \\ \\ " alt="
MAXImum [283]

Answer:

Oxidation–reduction or redox reactions are reactions that involve the transfer of electrons between chemical species (check out this article on redox reactions if you want a refresher!). The equations for oxidation-reduction reactions must be balanced for both mass and charge, which can make them challenging to balance by inspection alone. In this article, we’ll learn about the half-reaction method of balancing, a helpful procedure for balancing the equations of redox reactions occurring in aqueous solution.
