There are 100 degrees between the freezing (0°) and boiling points (100°) of water on the Celsius scale and 180 degrees between the similar points (32° and 212°) on the Fahrenheit scale.
Problem: Two scientists are doing an experiment designed to identify the boiling point
Answer: 250°F is the higher temperature by 2°F
<h2>
Answer:</h2>
<h3>Hg2 ( NO2 )2</h3>
<h2>Explanation:</h2>
<h3>Formula of mercury ( 1 ) dioxonitrate 111 is Hg2 ( NO2 )2//</h3>
It's a compound because it's formed from an ionic bond between calcium and carbon so it's an ionic compound
Explanation:
The experiment is performed at a constant atmospheric pressure. The experiment proceeds by placing an empty flask in a boiling water bath. As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant.
Answer:
Opposite poles of attract each other and make bonds.
Explanation:
Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.
