Answer:
The most important information is: financial charges, annual fees, minimum payments and how the balance is calculated.
Explanation:
A Schumer Box is a table where the credit card companies disclose all the terms and conditions necessary to make a contract with them, as well as disclose all fees, charges, balances and elements that make up the credit card.
All information shown on a Schumer Box is important, but the most important is that which deals directly with the customer's money or balance. This information is: financial charges, annual fees, minimum payments and how the balance is calculated.
2 Ionic bonds form between metal atoms and nonmetal atoms.
4 The less electronegative atoms transfers one or more electrons to the more electronegative atom.
5 The metal atom forms a cation and the nonmetal atom forms an anion.
7 The attraction between ions with an opposite charge forms an ionic bond.

Answer: 0.5 moles
Explanation:
Cr2(SO3)2 is the chemical formula for chromium sulphate.
Given that,
Amount of moles of Cr2(SO3)2 (n) = ?
Mass of Cr2(SO3)2 in grams = 128.9g
For molar mass of Cr2(SO3)2, use the atomic masses:
Chromium, Cr = 52g;
Sulphur, S = 32g;
Oxygen, O = 16g
Cr2(SO3)2 =
(52g x 2) + [(32g + 16g x 3) x 2]
= 104g + [(32g + 48g) x 2]
= 104g + [80g x 2]
= 104g + 160g
= 264g/mol
Since, n = mass in grams / molar mass
n = 128.9g / 264g/mol
n = 0.488 mole [Round the value of n to the nearest tenth which is 0.5
Thus, there are 0.5 moles in 128.9 grams of Cr2(SO3)2
