Answer:
ice
Explanation:
uhh concrete has rougher surface
The structural formula shown in the picture is the cyclic AMP or cyclic adenosine monophosphate. It is an essential component in RNA synthesis and metabolic processes. When it becomes non-cyclic after enzymatic reaction, you would have to disconnect the cyclic rings. When you do, you add 2 H atoms, one for each terminal end. The formula for cyclic AMP is C₁₀H₁₄N₅O₇P. Since there are three cyclic rings, you would have to add 6 hydrogen atoms.
Thus, the formula for noncylic AMP is C₁₀H₂₀
N₅O₇P.
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
The density increases.
Explanation:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
Answer: The equations of the above reactions are shown below
Explanation:
(a)
2K(s) + Cl2(g) ==> 2 KCl(s)
(b)
SrO(s) + H2O(aq) ==> Sr(OH)2(aq)
(c)
4Li(s) + O2(g) ==> 2Li2O(s)
(d)
2Na(s) + S (l) ===> Na2S
