Heat required for a system
can be calculated by the product of the specific heat, temperature difference
and the mass of the system. We calculate it as follows:
Q
= mCΔT
Q
= 50(0.06)(1)
Q
= 3 calories
<span>Therefore,
the correct answer from the choices listed is the second option, 3 calories.</span>
Answer:
Best regards.
Explanation:
Hello,
In this case, we relate the heat, mass, heat capacity and temperature when a thermal change is carried out as shown below:
Now, for the given data, we compute the absorbed heat (due to the temperature increase) as follows:
Best regards.
Answer: The option that represents the chemical properties of Hydrogen gas is A (It explodes with a flame.)
Explanation: Hydrogen gas is the lightest of all gases and the most abundant element in the universe. It's physical and chemical properties are the characteristics that distinguishes it from any other substance.
chemical properties of Hydrogen are the characteristics that determine how it will react with other substances or change from one substance to another. They include:
-It burns in air or oxygen to produce water.
-When mixed with air it can spontaneously explode by spark, flame or sunlight. I hope this helps. thanks.
