The answer is A. Water
Bronsted-Lowry base compounds are those that can accept protons
Bronsted-Lowry Acid Compounds are those that can recieve one
Water / H2O is an Amphoteric compund which mean that its molecul can act as a Base and Acid compound, so the answer is A.
Unequal heating of the atmosphere
What are the answer choices?
Answer:
<u>The temperature difference is</u>
Explanation:
The formula that is to used is :
ΔΔ
<em>where ,</em>
- <em>Δ is the heat supplied in calories = 300cal</em>
- <em> is the mass of water taken = m (assumed)</em>
- <em>Δ is the change in temperature</em>
- <em> is the specific heat of water = </em>
