Answer:
Any element with 7 electrons in the outermost shell will have similar properties. Thus other elements in the same column of the periodic table as chlorine will have similar properties. Elements in this column form what is called the Halogen series, which is composed of fluorine, chlorine, bromine, iodine, and astatine
Answer:
Percent error = 20%
Explanation:
The percent error is calculated using the following equation:
Percent error = |(approximate value - exact value)| / (exact value) x 100%
In this problem, the approximate value was 184 mL and the exact value was 230.0 mL
Percent error = |(184 mL - 230.0 mL)| / (230.0 mL) x 100% = 20%
Answer:
31°C
Explanation:
Using the ratio, we can find the temperature of the gas at 705mm.
725mm : 32°C
705mm : <em>x</em>
[ <em>x</em> is the temperature we have to find ]
Cross multiply the ratios.
725<em>x</em> = 705 × 32
725<em>x</em> = 22560
<em> x</em> = 
= <u>31°C</u>
