The amount of heat required to melt 15.0 grams of ice at 0.0º C is<u> 4950 J.</u>

<h3>What is the amount of heat required to melt 15.0 grams of ice at 0.0º C?</h3>

The amount of heat required to melt 15.0 grams of ice at 0.0º C is calculated from the formula given below:

Amount of heat = mass * latent heat of fusion of ice

The latent heat of fusion is the amount of heat required to convert a unit mass of ice at 0.0º C to water at 0.0º C

The latent heat of fusion of ice is 330J/g

mass of ice = 15.0 g

Amount of heat required = 15.0 g * 330 J/g

Amount of heat required = 4950 J

The acidic ingredient in vinegar is acetic acid. The pH of vinegar is around 2.4, and the molar concentration of acetic acid in
IrinaK [193]

Answer: The value of acid ionization constant K_a for acetic acid is 1.87\times 10^{-5}

Explanation:

CH_3COOH\rightarrow H^+CH_3COO^-

 cM              0             0

c-c\alpha        c\alpha          c\alpha  

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

Give c= 0.85 M and pH = 2.4

pH=-log[H^+]

[H^=}=c\times \alpha=10^{-2.4}=3.98\times 10^{-3}

K_a=?

Putting in the values we get:

K_a=\frac{(3.98\times 10^{-3})^2}{(0.85-3.98\times 10^{-3})}=1.87\times 10^{-5}

Thus the value of acid ionization constant K_a for acetic acid is 1.87\times 10^{-5}

A student makes several observations about a piece of iron. Which observation describes a chemical property of the iron?
Natasha2012 [34]

Here we have to identify a piece of iron by its chemical property.

There are several chemical properties of iron for its identification but the simplest way to identify one of the renowned chemical property of iron is the formation of rust on iron in presence of water.

The iron in presence of water forms different types of iron oxides like hydrated Iron (III) oxide [Fe₂O₃.nH₂O], Iron (III) oxide-hydroxide [FeO(OH). Fe(OH)₃].

The rust is brown in color and forms only by keeping the iron piece in atmosphere. Although the humidity has an effect on the formation. The more humid the atmosphere there will be more chance to form rust on iron rod.
