Geology and astronomy are two types of earth science. Geology is the study of rocks and minerals and astronomy is the study of space.
Answer:
1- bromopentane 1- bromo-3-methylbutane 1-bromo2-methylbutane 2-bromo-2-methylbutane
Explanation:
SN square reaction is a concentrated reaction. All the bond making and bond braking occur in one step
The nucleophile attack the back side of the carbon that bears the halide and replace it
Answer:
1A: ns^1
2A: ns^2
5A: ns^2np^3
7A: ns^2np^5
Explanation:
<u>According to IUPAC, the columns 1A, 2A, 5A, and 7A correspond to the groups, 1, 2, 15 and 17, respectively</u>.
The outer electron configuration of these columns are the following:
Column Outer electron configuration
1A ns^1
2A ns^2
5A ns^2np^3
7A ns^2np^5
Therefore, for the column 1A the s orbital has only one electron, for the column 2A has the s orbital completed with 2 electrons, for the column 5A the number of electrons in the s orbital is complete (2) and the number of electrons in the p orbital is 3, for the column 7A the s orbital has 2 electrons and the p orbital has 5 electrons.

There were two methods that Lord Rayleigh used in his experiment. First, nitrogen was obtained from the atmosphere by passing air over hot copper. Second, air was bubbled through an ammonia mixture, then passed over hot copper. The second method would have a greater mass of nitrogen than the first, <em>because the nitrogen from the atmosphere was contaminated by the nitrogen from the ammonia mixture.</em>
Answer:
Empirical formula of 81.8 carbon and 18.2 hydrogen
Steps
- Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
- Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>
