Answer:
6750 J
Explanation:
The specific heat capacity of iron is 450 J/kg/K
Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.
Therefore;
m = 3 kg, c = 450 J/kg/K and θ = 5°C
Quantity of heat = 3 × 450 × 5
<u>= 6150 Joules</u>
They are all living things in an ecosystem
Xenon, because the amount of protons=the atomic number, and Xenon’s atomic number is 54. Some elements with similar chemical properties would be Neon, Helium, Argon, Krypton, Nitrogen, etc because they are all in the period #18, which means they have similar properties. They are all noble gases. Hope this helps :)
