Your body uses it to build and repair tissue. You need it to make enzymes, hormones, and other body chemicals. It is an important building block of bones, muscles, cartilage, skin, and blood. Along with fat and carbohydrates.
2h-7 I had that before unless I’m tripping but I did rechecked
Answer:
D.A high temperature will make it spontaneous.
Explanation:
we know that
Δ G = Δ H - TΔS
For spontaneous reaction
Δ G should be negative . If Δ G = 0
Δ H = TΔS
T = Δ H / Δ S
At temperature above this T , Δ G becomes negative if Δ S and ΔH are positive .
So at a high temperature will make it spontaneous.
Answer:
There is 61.538% oxygen in Al2(SO4)3.
Explanation:
Wt Of oxygen in the compound = 12*16 = 192 amu.
Total Wt. Of the compound = 2*12+3*32+12*16 = 312 amu.
Thus, percent of oxygen = Wt of oxygen/total Wt. Of compound *100
= 192/312 * 100=61.538 %
Answer:
The likely causes inferred about the differences in times observed are;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water
Explanation:
The factors that affect the boiling point of water includes;
1) The amount of heat supplied, to the water
2) Vapor pressure above the water surface
3) Presence of impurities in the water
Therefore, the most likely causes for the difference in the times observed for the water to boil in the order of increasing probability of cause and effect are therefore;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water.
