The balanced chemical equation:
3 NH₃ + H₃PO₄ → (NH₄)₃PO₄
From the equation we see:
3 moles of NH₃ gives 1 mole (NH₄)₃PO₄
0.085 mole NH₃ will gives ?? mole (NH₄)₃PO₄
By cross multiplication:
number of moles of (NH₄)₃PO₄ = 0.085 * 1/3 = 0.028 mole

During evaporation, the volume of the liquid decreases and the liquid becomes what??? ​
oee [108]

Answer:

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Once water evaporates, it also helps form clouds

A mixture of 0.600 mol of bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C.
Kay [80]

The equilibrium constant for this reaction at 350°C is D. 282.

<h3>Equilibrium constant</h3>

A dynamic chemical system approaches chemical equilibrium constant when enough time has passed and its composition no longer exhibits any discernible propensity to change further. The equilibrium constant of a chemical reaction is the value of its reaction quotient in this condition. The equilibrium constant is independent of the initial analytical concentrations of the reactant and product species in the mixture for a specific set of reaction conditions. Understanding equilibrium constants is crucial for comprehending many chemical systems as well as biological processes like the transport of oxygen by hemoglobin in the blood and the maintenance of acid-base homeostasis in the human body. There are many different kinds of equilibrium constants, including stability constants, formation constants, binding constants, association constants, and dissociation constants.

The number of joules needed to raise the temperature of 100 grams of water by 10°C is the same as the number of joules needed to
kirill115 [55]

Answer:

1°C

Explanation:

We know that the heat required to raise the temperature is given by :

Q=mc\Delta T

m is mass

c is specific heat

\Delta T is the change in temperature

ATQ,

m_1c\Delta T_1=m_2c\Delta T_2\\\\m_1\Delta T_1=m_2\Delta T_2\\\\\dfrac{100}{1000}=\dfrac{\Delta T_2}{10^{\circ}}\\\\\Delta T_2=1^{\circ}C

Hence, the required temperature is 1°C.
