Specific heat capacity= Quantity of heat/massxΔT
Shc of iron (constant)= 0.4494J/³C for 1g
1.49kg=1490g
Q=1490x(22-155)x0.4494

Answer:
Valence electrons
Explanation:
In a period, the number of valence electrons increases (mostly for light metal/elements) as we move from left to right side
The amount of energy required to remove the most loosely bound electron in1 mole of an atom in its neutral gaseous state. Atomic radius is smaller, great nuclear charge (pulling power of protons on less electrons)
Answer:
i think the answer is letter C. From 35°c to 45°c
Explanation:
sorry if it is wrong
90 grams due to laws of conservation of mass. Output mass = input mass. Mass can never be created or destroyed.
