The subatomic particle which will be attracted by a positively charged object is: Choice 3: Electrons.
By law of electricity; like charges repel while unlike charges attract.
In essence, the subatomic particle which will be attracted to a positively charged object is a negatively charged particle.
Since, protons are positively charged, neutrons have no charge, positrons are positively charged but electrons are negatively charged,
The subatomic particle which will be attracted by a positively charged object is; Electron.

It was by far "warm and wet growing seasons" that was the most important factor in terms of the South's economic development. Cotton and tobacco were the biggest exports.
Explanation:
These crops created tons of cash, had massive markets round the world, however required a stable and enormous hands to grow and harvest them.The yank South is understood for its long, hot summers, and wealthy soils in stream valleys creating it a perfect location for growing cotton. the various southern seaports and riverside docks allowed shipping cotton to remote destinations. By 1860, Southern plantations equipped seventy fifth of the world's cotton, with shipments from Houston, city, Charleston, Mobile, Savannah, and some different ports. The unquenchable European demand for cotton was a results of the commercial Revolution that created the machinery and factories to method raw cotton into vesture that was higher and cheaper than hand-made product.

5.65 - this one is correct
Answers
Answer:
5.65 is the pH.
Explanation:
I am assuming that you are asking for confirmation on your answer. The answer is 5.65.
You would do:
[pOH] = -log[OH-]
= -log[4.5*10^-9]
equals about 8.3468
To find pH your would subtract the pOH from 14.
14-8.3468 = 5.65 << Rounded to match the answer choices.

Answer:
Explanation: The element with atomic number 20 consists 20 electrons and as atomic number is specific to an element, atomic number is of element calcium.
The nearest noble gas to calcium is argon with 18 electrons with configuartion according to afbau's rule, in which orbitals are arranged in order of increasing energies.
Thus electronic configuartion of calcium in terms of noble gas configuration is:
