Answer:
fe+s is a mixture of iron and sulphur and it can be separated by magnetic separation. But FeS is a compound formed by heating iron and sulphur together.it can't be separated by any method.
Explanation:
The given reaction will shift towards cis-2-butene once placed in equilibrium. This can be determined by calculating the reaction quotient and comparing it with the equilibrium constant.
The reaction could either shift towards the cis-2-butene or trans-2-butene depending on whether the reaction quotient, Q, is lesser or greater than the equilibrium constant, Kp.
Bear in mind that Kp = Ptrans/Pcis. Let's say that Pt is the partial pressure of trans-2-butene and Pc is the partial pressure of cis-2-butene at equilibrium. If we start with 5 atm of each gas, the change in Pc is -x and the change in Pt is +x.
So, Kp = (5+x)/(5-x). We are given that Kp = 3.4. Solving these two equations will show that x is a negative value, which means that the system shifts towards cis-2-butene.

For the isomerization reaction cis-2-butene ⇌ trans-2-butene, with an initial pressure of 5.00 atm for both gases and a Kp of 3.40, the system will shift towards the product, trans-2-butene, as Kp > Qp (1). This reflects the principle that a chemical system at equilibrium will shift to counteract any change.
In terms of the equilibrium constant (K), for gas-phase reactions, Kp represents equilibrium in terms of partial pressures, while Kc represents it in molar concentrations. For instance, in the isomerization reaction given cis-2-butene ⇌ trans-2-butene, Kp is given as 3.40. To determine the behavior of the system, we need to compare it to reaction quotient (Q). Given that the flask initially contains 5.00 atm of each gas, Qp is 1 (since Qp = partial pressure of trans-2-butene / partial pressure of cis-2-butene). Since Kp > Qp, the reaction will shift towards the products, hence the system will shift towards trans-2-butene. From this, it is clear that the equilibrium constant and reaction quotient play vital roles in determining the direction of shift in a chemical equilibrium.

Answer:
171.8°C
Explanation:
V1= 1780ml, V2= 2.55L= 2550L, T1= 273+37.5= 310.5
T2=?
Applying
V1/T1 = V2/T2
1780/310.5 = 2550/T2
T2= 444.8K -273 = 171.8°C
Answer:
metallic bonds are defined as those in which metals share valence electrons for example when sodium metallically bonds with itself each atom is sharing the electrons in the third orbital with up to eight other atoms the same thing happens with magnetism or other metals metallically bond to themselves.
Answer:
a) Moles of iodine molecules = 0.0748 moles of Iodine molecules
b) Moles of iodine atoms = 0.150 moles of iodine atoms
c) Number of iodine atoms = 9.03 * 10²² atoms
d) Number of iodine molecules = 4.50 * 10²² molecules
Note: The complete question is found in the attachment below.
Explanation:
a. Number of moles of iodine molecules in 19.0 g of I₂
Molar mass of iodine molecule = 2 * 127 g/mol = 254g/mol
Number of moles = mass / molar mass
Number of moles = 19.0 g / 254 g/mol
Moles of iodine molecules = 0.0748 moles of Iodine molecules
b) Number of moles of iodine atoms
I mole of iodine molecules contains 2 moles of iodine atoms
Therefore, 0.0748 moles of iodine molecules will contain 2 * 0.0748 moles of iodine atoms
Moles of iodine atoms = 0.150 moles of iodine atoms
c) Number of iodine atoms = number of moles of iodine atoms * 6.02 * 10²³
Number of iodine atoms = 0.150 * 6.02 * 10²³
Number of iodine atoms = 9.03 * 10²² atoms
d) Number of iodine molecules = number of moles of iodine molecules * 6.02 * 10²³
Number of iodine molecules = 0.0748 * 6.02 * 10²³
Number of iodine molecules = 4.50 * 10²² molecules
