The amount of heat energy added to silver to heat it from 25°C to 100°C is :
8737.5 J
<u>Given data: </u>
mass of silver ( m ) = 500 g
T1 = 25°C
T2 = 100°C
s ( specific heat of silver ) = 0.233 J/g.c
<h3 /><h3>Determine the amount of heat required </h3>
Applying the formula below for heat ( Q )
Q = ms * ΔT
= 500 * 0.233 * ( 100 - 25 )
= 8737.5 J
Hence we can conclude that the The amount of heat energy added to silver to heat it from 25°C to 100°C is : 8737.5 J.

well its evaporation cuz it the suns heat heated the ice to the point where it turned to a gas, it could be conduction cuz the heat of the sunshine conducted the ice and turned it to a gas but that would be evaporation too so its not onduction, its not a chemical change cuz theres no new molecule the substance is itself, and its not a sudden change obviously
so the answer is A. evaporation~~~
Answer : Option A) a tiny fragment or piece of matter particle.
Explanation : Atom are the tiny particles of a matter including particles; <span>The definition of an atom can be stated as the smallest component of any element, which can be characterized by sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons. </span>
Answer:
because they emit liquid waste wich is later dumped into the ocean causing a lot of harm and many fatalities in sea life
Explanation:
Chemical reaction: PCl₅ → PCl₃ + Cl₂.
n(PCl₅) = 0,366 mol.
V(PCl₅) = 4,45 L.
c(PCl₅) = n(PCl₅) ÷ V(PCl₅).
c(PCl₅) = 0,366 mol ÷ 4,45 L.
c(PCl₅) = 0,082 mol/L.
Kc = 1,80.
[PCl₃] = [Cl₂] = x.
Kc = [PCl₃] · [Cl₂] ÷ [PCl₅].
1,80 = x² ÷ (0,082 mol/L - x).
Solve quadratic eqaution: x = [PCl₃] = 0,078 mol/L.
[PCl₅] = 0,082 mol/L - 0,078 mol/L.
[PCl₅] = 0,004 mol/L.
