Answer:
the unit for electric current is ampere.
Explanation:
Dogs
Hey There!
Volume = 4.7 L
Molarity = 4.23 M
Therefore:
n = M *V
n = 4.23 * 4.7
n = 19.881 moles of HCl
hope this helps!
Q = 4.056 J
∴ m = 406.0 mg = 0.406 g
∴ <em>C </em>= 1.85 J/g.K
∴ T1 = 33.5°C ≅ 306.5 K
∴ T2 = 38.9°C = 311.9 K
⇒ ΔT = 311.9 - 306.5 = 5.4 K
⇒ Q = (0.406 g)(1.85 J/gK)(5.4 K)
⇒ Q = 4.056 J
The period number of krypton is 4
