Answer:

c) non polar Covalent

Explanation:

this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )

1. For every 5.00 mL of milk of magnesia there are 400. mg of magnesium hydroxide. How many mL of milk of magnesia do we need to

forsale [732]

Answer:

1. 6.50mL

2. pH = 13.097

Explanation:

1. The neutralization of HCl with Al(OH)₃ is:

3HCl + Al(OH)₃ → Al(Cl)₃ + 3H₂O

40.0mL ≡ 0.0400L of 0.500M HCl are:

0.0400L × (0.500mol / L) = 0.0200 moles of HCl

Based on the neutralization, 3 moles of HCl react with 1 mole of Al(OH)₃, thus, the moles of Al(OH)₃ that react with 0.0200 mol of HCl are:

0.0200mol HCl × (1mol Al(OH)₃ / 3mol HCl) = 0.00667 moles of Al(OH)₃. In grams:

0.00667 moles Al(OH)₃ × (78g / 1mol) = 0.520g of Al(OH)₃ ≡ 520mg

As 5.00mL of milk magnesia contain 400mg of Al(OH)₃, the mL of milk magnesia required for a complete reaction are:

520 mg Al(OH)₃ × (5.00mL / 400mg) = 6.50mL

2. The reaction of lithium hydroxide (LiOH) with perchloric acid (HClO₄) is:

HClO₄ + LiOH → LiClO₄ + H₂O

The reaction is 1:1.

Moles of LiOH and HClO₄ are:

LiOH: 0.0500L × (0.350mol / L) = 0.0175 moles of LiOH

HClO₄: 0.0300L × (0.250mol / L) = 0.0075 moles of HClO₄

Assuming the reaction goes to completion, moles of LiOH that remains are:

0.0175 mol - 0.0075 mol = 0.0100 moles of LiOH. The total volume is 80.0mL, 0.0800L. Thus, molarity of LiOH is:

0.0100 mol / 0.0800L = 0.125 M of LiOH

It is possible to obtain the pOH of the solution thus:

pOH = -log (OH) = -log 0.125M = 0.903

As pH = 14- pOH,

pH = 14 - 0.903 = 13.097

I hope it helps!

When performing dimensional analysis, we usually use conversion factors. What is a conversion factor?

lora16 [44]

Answer:

A conversion factor is a variable that transforms the dimension of one variable into the terms of another variable.

Explanation:

Let be $x$ and $y$ two variables with diferent dimensions (units), $r$ is a conversion if transforms the dimension of one variable into the terms of the other variable. That is:

$y = r\cdot x$ (1)

Where:

$x$ - Input, [input unit]

$y$ - Output, [output unit]

$r$ - Conversion factor, [output unit] per [input unit]
