Answer:
kujgedyjmnyged\jmngv\gedkjmyten
Explanation:
Absolute brightness and temperature
Answer: 0.45 J / g °C
Explanation: solution attached.
Heat is equal to the product of mass, specific heat and change in temperature.
Q= mc∆T
Derive the equation to find c
c = Q / m∆T substitute the values
c = 21.6 J / 2.0g ( 24°C - 5°C)
c = 0.45 J / g ° C
In the reactant side, Hydrogen Phosphate (H2PO4) is an acid while H2O is amphiprotic, meaning it can be a base or acid. Therefore, in this process for the reaction to occur, H2O acts as the base while H3O+ acts as its conjugate acid. The answer is A.
