Answer: To determine the mole ratio

Explanation:

A balanced chemical equation is needed ,because it helps to determine the mole ratio of acid and base.

The mole ratio ensures that the number of moles of H+ provided by the acid is equal to number of moles of OH- ion provided by the base, For neutralization to occur, this must be the case.

An object’s mass is determined to be 32.5 g. When the object is placed in a graduated cylinder containing 175 mL of water, the w
MakcuM [25]
<h3><u>Given :-</u></h3>
  • Mass of object = 32.5 g

<h3><u>To Find </u><u>:</u><u>-</u></h3>
  • Dentity of the material

<h3><u>Solution:- </u></h3>

When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed

So, Volume of object

= Increased Volume - Initial volume

= > 187.5 -175

= > 12.5 ml

Since 1 ml = 1 cm³ we can write

\quad12.5 ml = 12.5 cm³

Now,

\green{ \underline { \boxed{ \sf{Density=  \frac{Mass}{Volume}}}}}

Putting Values -

\begin{gathered}\\\implies\quad \sf Density =  \frac{32.5}{12.5}  \\\end{gathered}

\begin{gathered}\\\implies\quad \sf Density =  \frac{325}{125}  \\\end{gathered}

\begin{gathered}\\\implies\quad \sf Density = 2.6 g/cm^3 \\\end{gathered}

>> The density of the material is 2.6 g/cm³

Why rusting takes place more readily in coastal areas
kobusy [5.1K]
Corrosion is a better word to use as Iron is the metal that 'rusts' and it happens more in coastal areas because coasts are humid. Humidity reacts with the metal causing it to corrode and wakening it
