The choices that should have accompanied this question were:

My answer is B. 2.
Below is an explanation, I found while doing the research.
<span>Phosphate needs 3 electrons each totaling 6 electrons so each zinc will need to give up 2 electrons.
Phosphate wants to imitate the electron configuration of Argon because noble configurations are the most stable. With P getting the extra electrons the valence shell will be 3s2 3p6, which is the same as Argon. Without the extra electrons, the P valence shell looks like this 3s2 3p3, now you can see why each phosphorus wants 3 more electrons, that will make it 3s2 3p6, just like Argon.</span>
Answer:
- Dalton used creativity to modify Proust's experiment and interpret the results.
- Thomson used creativity to interpret the results of the cathode ray tube experiment.
Explanation:

An atomic number is <span>the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table or chart.</span>
We can use the ideal gas law equation to find the pressure
PV = nRTwhere
P - pressure
V - volume - 2.6 x 10⁻³ m³
n - number of moles - 0.44 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 25 °C + 273 = 298 K
substituting the values into the equation,
P x 2.6 x 10⁻³ m³ = 0.44 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
P = 419 281.41 Pa
101 325 Pa is equivalent to 1 atm
Therefore 419 281.41 Pa - 1/ 101 325 x 419 281.41 = 4.13 atm
Pressure is 4.13 atm
When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. It could be A I’m not sure if this helps.
