Answer:
Yes
Explanation:
If Mg + 2HCI is Blanced then MgCI2 + H2 is also Blanced . So yes
Answer:
Heating raw potatoes in hot water will make the starch granule swell and absorb water, becoming soft and easier to digest. Eggs contain mostly protein in liquid form. Heating protein will make it undergo denaturation process. The protein structure changes, becoming firm solid and easier to digest.
Answer:
Given : Diatomic molecule at 273K
'q' absorbed = positive = +100Cal = 100 x 4.184J = 418.4J
'W' done by system = negative = -209J
By first law of thermodynamics;
ΔU = q + W = 418.4 + (-209) = 209.4J
We know for diatomic molecule Cv=25R and CvΔT=ΔU
CvΔT=209.4
25RΔT=209.4
ΔT=5R209.4×2
And, Heat exchange=Cm×ΔT
where; Cm is molar heat capacity
Cm=ΔTHeat Exchange
substituting values for Heat Exchange = 418.4 and ΔT=5R209.4×2
Cm=5R
