Which end of a water molecule is positive and which end is negative and why?

1 answer:

6 0

The region or the end of water molecule that is partially positive would be where the Hydrogens are. The end that is partially negative, is where the Oxygen is. These partial charges, are because of the large electronegativity differences present between the hydrogens and Oxygen in the molecule. Thus unequal electron distribution or sharing occurs between the atoms in the molecule causing it to be polar and possess the partial charges.

Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic aci

miv72 [106K]

Answer:

0.500 moles of oxygen

Explanation:

<em>Full question says: "Calculate the moles of oxygen needed to produce 0.500 moles of acetic acid.</em>

<em />

The reaction of ethanol (C₂H₅OH) with oxygen (O₂) is:

C₂H₅OH + O₂ → CH₃COOH + H₂O

<em>Where 1 mole of ethanol reacts per mole of oxygen to produce 1 mole of acetic acid (CH₃COOH) and 1 mole of water</em>

<em />

Based on the chemical equation (1 mole of oxygen produce 1 mole of acetic acid; Ratio 1:1). Thus, if you want to produce 0.500 moles of acetic acid you will need:

<h3>0.500 moles of oxygen</h3>

Mg + 2 AgNO₃ → Mg(NO₃)₂ + 2 Ag How many grams of magnesium nitrate, Mg(NO₃)₂, are formed when 9.87 moles of silver nitrate, AgNO

Aleksandr-060686 [28]

Mass of Magnesium nitrate formed : 731.86 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

Mg + 2AgNO₃ → Mg(NO₃)₂ + 2 Ag

moles of silver nitrate, AgNO₃ = 9.87

mole ratio AgNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :

$\tt \dfrac{1}{2}\times 9.87=4.935$
