Answer:

<em>Correct option is D) The neutron has a neutral charge, which made it impossible to discover using  previous experiments with positive and negative charges.</em>

Explanation:

The protons are the positively charged particles of an atom. The electrons are the negatively charged particles of an atom. As both the particles carry some kind of charge i.e either positive or negative, hence their discovery was easier.

The neutrons are the part of an atom which are neutral and do not carry any charge. Hence, their discovery took a more longer time as compared to the discovery of electrons and protons.

CH4(g) + 2O2(g) → CO2(g) + 2H2O(l): ΔH = −890 kJ
V125BC [204]

Answer:

The reaction of one mole of oxygen (O2) releases 445 kJ of energy.

Explanation:

Firstly, the reaction is exothermic since the sign of enthalpy change ΔH  is negative.

The balanced equation: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l): ΔH = −890 kJ,

Shows that 1 mole of CH₄ react with 2 moles of oxygen and releases 890 kJ.

So, every choice says that absorb is wrong (choice 1& 3).

Choice no. 4 is wrong since it says that 2 moles of methane releases 890 kJ, because only one mole release this amount of energy.

So, the right choice is The reaction of one mole of oxygen (O2) releases 445 kJ of energy.

What evidence led to the conclusion that cathode rays had a negative charge?
max2010maxim [7]
In Thomson's cathode-ray experiment,<span>He sucked all of the air out of the tube, so only the ray was inside. He then concluded that the ray was negatively charged because the ray came from the cathode ray and went to the positively charged anode ray, so the cathode had to be negative or else it would have deflected away from the anode. 

Hope this helped ! Let me know if you need more information ! :)</span>
