The ratio of 10 milligram and 5 nanogram of a substance is (A) 1:5x10 (B) 2:1x10 (C) 1x10^3:2 (D) 2x10^6:1. An element X with its outermost element having 2p forms two compounds with another element Y: the number of atoms of element Y per molecule in these compounds are (A) 1 and 2 (B) 1 and 3 (C) 2 and 3 (D) 1 and 4.
Understand the Problem
The question is asking about the ratios and characteristics related to certain chemical compounds, specifically in regards to the borax bead test for copper. It involves understanding the ratios of weight between milligrams and nanograms and the properties of the compounds formed with an element having specific electron configurations.
Answer
(D) 2x10^6:1
The final answer is (D) 2x10^6:1.
Answer for screen readers
The final answer is (D) 2x10^6:1.
More Information
10 milligrams is 10,000,000 nanograms, making the ratio to 5 nanograms very large.
Tips
Common mistake: Not converting milligrams to nanograms correctly.
