The volume of one mole of any gas at Standard Temperature and Pressure (1 atm and 0 degrees Celsius [273K]) is 22.4 L.
Answer:
The change in temperature that occurs when 8000 J of heat is used by a mass 75 g of water is 25.4 °C
Explanation:
H = mc ΔT
m = 75 g
c = 4. 200 J/ g °C
H = 8000 J
ΔT =?
Rearranging the formula, making ΔT the subject of formula;
ΔT = H / m c
ΔT = 8000 / 75 * 4.200
ΔT = 8000 / 315
ΔT = 25.4 °C
Answer:
H2O
Explanation:
There are 2 hydrogen atoms and 1 oxygen atom
A common use of bases is to reduce indigestion. Hence, option D is correct.
<h3>What is the base?</h3>
A base is a substance that can neutralize the acid by reacting with hydrogen ions.
Bases are substances whose solutions have a pH value of more than 7. Bases are bitter in taste.
Whereas acids are the substances whose solutions have a pH value of less than 7. Acids are sour in taste.
When an excess of acid is formed in the human stomach then an antacid tablet which is basically a base is consumed that helps in reducing indigestion.
Therefore, we can conclude that the common use of bases is to reduce indigestion.
