Answer:
I believe the organelle should replace the question mark!
Answer:
-162,5 kJ/mol
Explanation:
Cl(g) + 2O2(g) --> ClO(g) + O3(g) ΔH = 122.8 kJ/mol (as we used the reaction in the opposite direction, it will turn the enthalpy from exothermic to endothermic)
2O3(g) --> 3O2(g) ΔH = -285.3 kJ/mol
Cl(g) + O2(g) --> ClO(g) + O3(g) ΔH = 122.8 kJ
+ 2O3 (g) --> 3O2(g) ΔH = - 285.3 kJ
O3(g) + Cl(g) --> ClO(g) + 2O2(g) ΔH = 122.8 + (-285.3) = -162,5 kJ
Answer:
Hailey should add, they are inexpensive to produce.
Explanation:
Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.
Reason being why the others are wrong, synthetic polymers are <u>not</u> biodegradable as they are made in a factory with oils. Synthetic polymers are <u>not</u> flexible due to them being used for harder products. Synthetic polymers are <u>not</u> recycled cheaply as they are made with chemicals which makes it very hard to recycle.
Answer: Option (B) is the correct answer.
Explanation:
It is known that flow of electrons is known as current. Also, we know that electrons carry a negative charge.
Therefore, when parallel wires carrying current in the same direction then due to the same charge there will be repulsion between the electrons.
Thus, we can conclude that Ampere showed that parallel wires carrying current in the same direction would repel each other.
Answer:
5.23 moles of C₁₀H₈N₂O₂S₂
Explanation:
In order to find the moles of dipyrithione we need to know its formula:
C₁₀H₈N₂O₂S₂
1 mol of N contains 6.02×10²³ atoms
We need to find out the moles of 6.3×10²⁴ atoms of N
6.3×10²⁴ atoms . 1 mol /6.02×10²³ atoms = 10.4 moles of N
Therefore, we know that 1 mol of dipyrithione has 2 moles of N, so we need to make this rule of three:
2 moles of N are contained in 1 mol of C₁₀H₈N₂O₂S₂
10.4 moles of N must be contained in (10.4 . 1) /2 = 5.23 moles of C₁₀H₈N₂O₂S₂
