Answer:
Q = 197505J
Explanation:
Mass (m) = 825g
Specific heat capacity (c) = 1.8J/g°C
Initial temperature (T1) = 22°C
Final temperature (T2) = 155°C
Heat energy (Q) = ?
Q = mc∇t
Q = mc(T2 - T1)
Q = 825 * 1.8 * (155 - 22)
Q = 1485 * 133
Q = 197505J
The heat energy required to raise it through that temperature is 197505J
Velocity = displacement/time = 15/30 = 0.5miles/hr.
<em> $ 434.40</em>
<em>41 miles ............ 1 gallon</em>
<em>4700 miles .......x gallon</em>
<em>x = 4700×1/41 = 114.63 gallons</em>
<em />
<em>114.63 gallons×$3.79 ≈ $ 434.40</em>
In most cases, carbon shares electrons with other atoms (usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity. Examples of covalent bonds formed by carbon include carbon-carbon, carbon-hydrogen, and carbon-oxygen bonds
