How many joules of energy would it take to raise the temperature of 2.5 grams of magnesium metal from
25°C to 50°C
Report your answer with two significant digits, leave a space, and add the unit.

Q = 63.75J

Explanation:

Mass = 2.5g

Initial temperature (T1) = 25°C

Final temperature (T2) = 50°C

Specific heat capacity of Mg = 1.020J/g°C

Heat energy = ?

Heat Energy (Q) = mc∇T

Q = heat energy

M = mass of substance

C = specific heat capacity of substance

∇T = change in temperature = T2 - T1

Q = mc∇T

Q = mc(T2 - T1)

Q = 2.5 × 1.020 × (50 - 25)

Q = 2.55 × 25

Q = 63.75J

The heat energy required to raise magnesium metal from 25°C to 50°C is 63.75J

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
