How much heat energy is required to raise the temperature of 50g of bromine from 25°C to 30°C? [Specific heat capacity of bromin
tia_tia [17]

Answer:

56.5J

Explanation:

<em>To </em><em>find</em><em> </em><em>the </em><em>heat </em><em>energy</em><em> </em><em>required</em><em> </em><em>use </em><em>the </em><em>formula</em><em> </em><em>for </em><em>the </em><em>specific</em><em> </em><em>heat </em><em>capacity</em><em> </em><em>which </em><em>is </em>

<em>c=</em><em>quantity</em><em> of</em><em> </em><em>heat/</em><em>mass×</em><em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>in </em><em>temperature</em>

<em>in </em><em>this </em><em>question</em><em> </em><em>c </em><em>is </em><em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>j</em><em>/</em><em>g,</em><em>the </em><em>mass </em><em>is </em><em>5</em><em>0</em><em>g</em><em> </em><em>and </em><em>the </em><em>change </em><em>in </em><em>temperature</em><em> </em><em>is </em><em>3</em><em>0</em><em>-</em><em>2</em><em>5</em><em>=</em><em>5</em>

<em>therefore</em>

<em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>=</em><em>Q/</em><em>5</em><em>0</em><em>×</em><em>5</em>

<em>Q=</em><em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>×</em><em>2</em><em>5</em><em>0</em>

<em> </em><em> </em><em> </em><em>=</em><em>56.5J</em>

<em>I </em><em>hope </em><em>this</em><em> helps</em>

MissTica

Answer:

\textbf{ \huge\boxed{ \sf ETHENE}}
