Answer:
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Explanation:
Answer:
Bicarbonate, the conjugate base of carbonic acid.
Explanation:
Answer:
B. Able to be lost or gained in chemical reactions.
At STP, it is at 273 K and 1.00 atm.
Use PV=nRT to and solve for n (number of mol of N2)
1.00 atm • 4.40L / 0.08206 Latm/molK • 273 K = 0.196 mol N2
There are two mol of N2 for every two mol of NH4NO2 (the number of mol of both are equal)
Find the molar mass of NH4NO2 = 64.1 g
Multiply the number of mol by the molar mass
0.196 mol • 64.1 = 12.6 g NH4NO2
The change in enthalpy shows on the graph is the red arrow shows that enthalpy is positive, indicating an endothermic reaction.
<h3>What is potential energy?</h3>
Energy is the basic thing to do any reaction or any process. There are many kinds of energy are present that are use indifferent processes.
Potential energy is the energy that is saved to do a work, or the energy that is present before a work occurred.
The graph is attaches below.
Thus, the correct option is A. The red arrow shows that enthalpy is positive, indicating an endothermic reaction.
