Answer:
0.385 J/g°C
Explanation:
Using the following formula, the specific heat of an elemental substance can be calculated:
Q = m × c × ∆T
Where;
Q = quantity of heat (J)
m = mass (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
Based on the given information, Q = 1375J, m = 50g, initial temperature = 22.8°C, final temperature = 94.2°C, c =?
Q = m × c × ∆T
1375 = 50 × c × (94.2 - 22.8°C)
1375 = 50 × c × 71.4
1375 = 3570c
c = 1375/3570
c = 0.3851
c = 0.385 J/g°C
Answer:
The body of the refrigerator isn’t made of magnetic material.
Explanation:
Same reason why a magnet doesn't stick to a paper or a plastic is the reason behind why Jack's refrigerator is acting out because may be it isn't made of magnetic materials like iron, steel etc, but rather made up of non magnetic things like porcelain, wood etc.
One side drops into fault
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:
