Wine goes bad soon after opening because the ethanol in it reacts with oxygen gas from the air to form water and acetic acid , t
ryzh [129]

The mass of ethanol is consumed by the reaction of 3.37g oxygen gas is 4.85g

Explanation:

The balanced equation for the chemical reactions is;

CH₃CH₂OH + O₂ → CH₃COOH + H₂O

The mole ratio between oxygen and ethanol in the reaction is 1 : 1

The molar mass of O₂ is 32g / mole. Therefore the O₂ moles consumes in the reaction is;

3.37 / 32

If the molar mass of ethanol is 46.07g/mole, and the ration of reaction in 1 : 1; Then the moles of ethanol consumed is;

3.37/32 * 46.07

= 4.85g

Which reason best explains why metals are ductile instead of brittle?
MaRussiya [10]

Answer: -

Metals are ductile instead of brittle because they have flexible bonds.

Explanation: -

Metals have a property called ductility.

It is the ability of a metal to be drawn into wires.

Metals due to greater bond flexibility are more ductile.

The most ductile metal known to man is Gold. Metallic wires find many applications in modern machinery particularly.

Usually ductility and malleability go together.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.
Ivanshal [37]

Answer:

Mass is the same but it weights 64 Newtons

Explanation:

First of Mass is the same in any sort of gravity. Now let's calculate weight

W = MG

where W = Weight

M = Mass

G = Gravity

W = (40kg)(1.6)

W = 64

Sorry for the spelling mistakes, hope this helps
