Wouldnt it be 25 because if voth forces are going in the same direction it would be adding so there for it is 25 N.
Answer:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. hope that helps
Explanation:
A=top
B=middle
C=bottom
Answer:
249.01 g/mol
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
Au(CN)₂
<u>Step 2: Identify</u>
Molar Mass of Au - 196.97 g/mol
Molar Mass of C - 12.01 g/mol
Molar Mass of N - 14.01 g/mol
<u>Step 3: Find MM</u>
Molar Mass of Au(CN)₂ - 196.97 + 2(12.01) + 2(14.01) = 249.01 g/mol
Answer:
You see the concentration decreased ten fold, from 1 M to 0.1 M.
You can simply increase the volume by ten times.
For example
If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.
If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.
C1 = starting concentration.
C2 = final concentration.
V is for volume.
So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.
1 M x V1 = 0.1 M x 50 mL
V1 = 5 mL
So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.

Answer: At the point when space experts take a gander at an article's range, they can decide its arrangement dependent on these frequencies. The most well-known technique stargazers use to decide the sythesis of stars, planets, and different articles is spectroscopy. This spread-out light is known as a range.
