<h2>Answer:</h2>

A pure metal has specific properties. Sometimes we need that metal but with modified properties. So for the modification of properties we make alloys.

<h3>Explanation;</h3>
  • An alloy is a mixture of two elements, one of which is a metal.
  • Alloys often have properties that are different to the metals they contain.
  • This makes them more useful than the pure metals alone.
  • For example, alloys are often harder than the metal they contain.

1. (8pt) Using dimensional analysis convert 600.0 calories into kilojoules
Ivanshal [37]

Answer:

1. 2.510kJ  

2. Q = 1.5 kJ

Explanation:

Hello there!

In this case, according to the given information for this calorimetry problem, we can proceed as follows:

1. Here, we consider the following equivalence statement for converting from calories to joules and from joules to kilojoules:

1cal=4.184J\\\\1kJ=1000J

Then, we perform the conversion as follows:

600.0cal*\frac{4.184J}{1cal}*\frac{1kJ}{1000J}=2.510kJ

2. Here, we use the general heat equation:

Q=mC(T_2-T_1)

And we plug in the given mass, specific heat and initial and final temperature to obtain:

Q=236g*0.24\frac{J}{g\°C} (34.9\°C-8.5\°C)\\\\Q=1495.3J*\frac{1kJ}{1000J} \\\\Q=1.5kJ

Regards!
