<h2>Collision Theory
</h2>
Explanation:
<h3>
The given statement is related to the collision theory -
</h3>
Collision theory was given by William Lewis in 1916.
This theory explains in a qualitative manner that in what way any chemical reaction occurs and the reason for the different reaction rates for different reactions.
<h3>
According to the collision theory -
</h3>
- Molecules must collide in order to react
- Sufficient amount of energy is needed for collisions (kinetic energy) so that the chemical bonds should break
- This energy used is known as the activation energy
- On the increase in the temperature, the kinetic energy of the molecule increases and the molecules move faster and collide with a proper orientation at an increased speed
- This increases the rate of a collision that in turn increases the breaking of the bond
Answer:
The answer to your question is 0.113 moles of Fe₂O₃
Explanation:
Data
moles of Fe₂O₃ = ?
mass of Fe₂O₃ = 18 grams
Process
1.- Calculate the molar mass of Fe₂O₃
Fe₂O₃ = (56 x 2) + (16 x 3)
= 112 + 48
= 160 g
2.- Use proportions to solve this problem. The molar mass is equivalent to 1 mol.
160 g of Fe₂O₃ --------------- 1 mol
18 g of Fe₂O₃ ---------------- x
x = (18 x 1)/160
x = 0.113 moles of Fe₂O₃
CuO(aq) + H2(g) → H2O(l) + Cu(s)
CuO= 64 + 16= 80g
1 mole of CuO → 1 mole of Cu
80g of CuO → 1 mole of Cu
20.50g of CuO → y
y= 20.50/80= 0.26mole.
Oxygen to sulfur is less polar than comparable bonds to oxygen because sulfur is less electronegative than oxygen.
In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. Fluorine is the element with the greatest electronegative charge, whereas francium has a very low electronegative charge. Within a set of elements, electronegativity values drop from top to bottom. Moving from left to right along a period improves electronegativity. This is caused by a decrease in atomic size and a rise in nuclear charge, which allows a shared electron pair to be more attracted to one another.

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the final pressure by using the Boyle's law as an inversely proportional relationship in pressure to volume at constant temperature:
Thus, we solve for our target, P2, to obtain:
