Answer:
0.744 M
Explanation:
IO⁻⁴(aq) + 2H₂O(l) ⇌ H₄IO⁻⁶(aq)
Kc = 3.5×10⁻²= [H₄IO⁻⁶] / [IO⁻⁴]
First let's<u> calculate the new concentration of IO⁻⁴ at equilibrium</u>:
0.904 M * 26.0 mL / 500.0 mL = 0.047 M = [IO⁻⁴]
Now we can<u> calculate [H₄IO⁻⁶] using the formula for Kc</u>:
3.5×10⁻²= [H₄IO⁻⁶] / [IO⁻⁴]
3.5×10⁻²= [H₄IO⁻⁶] / 0.047 M
[H₄IO⁻⁶] = 0.744 M
Answer: option C - Carbon and Hydrogen have similar electronegativity values.
Explanation:
Carbon form COVALENT compounds with hydrogen. Examples are methane CH4, ethane C2H6, propane C3H8.
Electronegativity is the power to attract electrons. It is used to predict whether a bond will be covalent OR not. It can also be used to predict if the resulting molecule will be polar or nonpolar
Thus, Carbon with an electronegativity value of 2.55; and Hydrogen with 2.20 shows close similarities and THUS result in NONPOLAR and COVALENT BOND of Propane

Answer:
The correct answer is - Luster.
Explanation:
Luster is a property that explains how the light is reflected on the surface of a mineral. Luster can be categorized with the help of if an element or mineral is metallic or non-metallic.
Pyrite has a shiny, opaque metallic luster which is similar to other metals. There are different types of luster other than metallic also found like, silky, dusty, pearly, waxy, and a few more.
