Answer: 4.) CH3O is the answer, which stands for Methoxide.
Explanation:
Explanation:
not sure but I think is quartz or feldspar minerals
The Earth holds livings things and even the layer has more complex layers in it (Also it's not white) And of course there are no oceans
Answer:
The correct answer is Option C (E1) and Option B (carbocation).
Explanation:
- Intramolecular immunity idols are considered as that of the formation mechanism with E1 responses or reactivity.
- Reactants with E1 were indeed obligations of both parties, meaning that an E1 reaction was conducted thru all the two stages known as ionization but rather deprotonation. Involves the absence of either an aromatic ring, a carbocation has been generated throughout the ionization solution.
Some other possibilities offered aren't relevant to the procedure outlined. So the above alternative is accurate.
The heat lost by copper(ii) sulfate is equal to heat absorbed by water since the total energy in the system remains constant according to the law of conservation of energy.
<h3>How can the number of moles be determined?</h3>
The number of moles of a substance is determined using the formula below:
- Number of moles = mass/molar mass
Assuming the mass of copper(ii) sulfate used is <em>Mc</em>, number of moles of copper(ii) sulfate used is:
- Moles of copper(ii) sulfate = <em>Mc</em>/159.60 moles
The heat absorbed by water is calculated using the formula below:
- Quantity of Heat, H = mass × specific heat capacity × temperature change
mass of water <em>=</em><em> </em> 10 g
Let temperature change be <em>Tc</em>
Heat<em> </em>absorbed<em> </em>by water = 10 × 4.186 × Tc = 41
86Tc
The change in internal energy, ΔU of copper(ii) sulfate, is given as:
where:
Q = heat absorbed by water
W = work done by or on the system
The enthalpy of the reaction is given as:
- ΔH= energy released or absorbed/moles of copper (ii) sulfate
Therefore, according to the law of conservation of energy, the total energy in the system remains constant.
