Answer:
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
Answer:
Three liquids can form something that will resemble into a solid because it depends on which liquids you use and because all three things can work together to make it into a solid with the ingredients that are in all three liquids they will make into a beautiful piece.
Explanation:
This is the correct answer!!
Well first off they can stop dumping harmful chemicals in our oceans.
Second, they could just limit the use of factories . May sound stupid but it works
Hope this helps!
B.) Copper
The alkaline battery gets its call because of the fact it has an alkaline electrolyte of potassium hydroxide, as adverse to the acidic electrolyte of the zinc-carbon batteries that are presented interior the same nominal voltages and actual length.
Answer:
Option A. 9.4 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 8 L
Initial temperature (T₁) = 293 K
Final temperature (T₂) = 343 K
Final volume (V₂) =?
V₁ / T₁ = V₂ / T₂
8 / 293 = V₂ / 343
Cross multiply
293 × V₂ = 8 × 343
293 × V₂ = 2744
Divide both side by 293
V₂ = 2744 / 293
V₂ = 9.4 L
Therefore, the final volume of the gas is 9.4 L
