Answer: Low melting points
Explanation:
Answer:
n= 0.303mol
Explanation:
From PV= nRT
R= PV/nT
Comparing 2-systems of baloons
P1V1/n1T1 = P2V2/n2T2
Since pressure and temperature are constant
V1/n1= V2/n2
23.5/5.2 = 14.9/n2
Simplify
n2= 0.303mol
Answer: D. They turn red litmus paper blue and taste bitter.
Explanation:
Acids are those substances which either donates hydrogen ions when dissolved in water. They have pH ranging from 1 to 6.9. They are sour in taste. They dissolve metals to give hydrogen gas. They turn blue litmus red.
Bases are those substances which either donates hydroxide ions when dissolved in water or donates a pair of electrons. They have pH ranging from 7.1 to 14. They are bitter in taste. They are slippery in nature. They turn red litmus blue.
Answer:
positive
Explanation:
lost of negative electron leaves one more positive charges than negative charges.
