Answer:
pH 4 represents an acidic
Answer:
—COOH
Explanation:
—COOH, acid group, containing 3 elements, C, carbon, O, oxygen, and H, hydrogen.
c. table salt is a metalloid with properties of both reactants
From Q = mcΔT, we can rearrange the equation to solve for mass, m = Q/cΔT. The specific heat capacity, c, of solid gold is 0.129 J/g °C. I'm assuming that the energy is given in joules, as it's not specified in the question as written.
m = Q/cΔT = (35.73 J)/(0.129 J/g °C)(40.85 °C - 0.85°C)
m = 6.92 g of gold was present
Porque la temperatura de la agua es neutral
