216 J of energy is required to raise the temperature of a piece of aluminum from 15.0º C to to 35º C.
ddd [48]

Answer: 12g

Explanation:

The amount of energy (Q) required to raise the temperature of a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Given that:

Q = 216 joules

Mass of aluminium = ? (let unknown value be Z)

C = 0.90 JºC-1g-1

Φ = (Final temperature - Initial temperature)

= 35°C - 15°C = 20°C

Then, Q = MCΦ

216 J = Z x 0.90 JºC-1g-1 x 20°C

216 J = Z x 18 J°g-1

Z = (216J/18 J°g-1)

Z = 12g

Thus, the mass of the aluminium is 12grams

Look up the active ingredient in baking soda. Write a molecular and net ionic equation when that active ingredient is mixed with
Volgvan

Answer:

The active ingredients in baking soda (NaHCO3) are

Na^+ and HCO3^-

when Baking soda reacts with Acetic acid

Molecular equation

 NaHCO3(aq) + CH3COOH(aq) → Na(CH3COO)(aq) + CO2(g) +H2O(l)

Ionic equation

Na^+ + HCO3^-  + CH3COOH →   Na^+ + CH3COO^-  +CO2 + H2O

as Na^+ is present on both sides so it will cancel out and the net ionic equation will be

HCO3^-(aq) + CH3COOH(aq) → CH3COO^-(aq) + CO2(g) + H2O(l)
