Answer:
134K
Explanation:
Using the ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas constant (0.0821 Latm/Kmol)
T = temperature (K)
Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?
3.25 × 4.738 = 1.4 × 0.0821 × T
15.3985 = 0.11494T
T = 15.3985/0.11494
T = 133.969
Approximately;
T = 134K
The car stopped due to a gravitational pull (gravity slowing it down) the energy is converted to kinetic energy and heat energy.
Answer:
0.124 M.
Explanation:
Hello!
In this case, since the nickel iodide has the following formula:
NiI₂
So its molar mass is 312.5023 g/mol, in order to compute the molarity of the iodide anion, we first need the moles in 2.90 g:
Now, since one mole of nickel(II) iodide contains two mole of iodide anions, we infer there are 0.0186 moles of iodide cations. Moreover, since the molarity is computed by dividing the moles of those ones by the volume of the solution in liters, 150 mL (0.150 L) as it does not change, it turns out:
Best regards!
The chemical energy, which is a type of kinetic energy explains the type of energy present in the wheels of a moving bus.
Explanation:
Kinetic Energy is the energy possessed by an object by virtue of its motion.
Kinetic Energy is present in every moving object. A moving bus, train,flying airplane, walking , running etc are some examples of Kinetic Energy.
Kinetic Energy is classified into two parts Rotational Kinetic Energy and vibrational Kinetic energy.
Kinetic energy depends on two things , the mass and the velocity of the object.
In the above example , in a moving bus,the wheels of the bus are also moving. So with motion, Kinetic energy gets formed.
