Answer:
No, it isn't a spontaneous reaction.
Explanation:
A spontaneous reaction is a reaction that requires no outside intervention to start.
All chemical reactions require energy.

Answer:
saturated is the correct one
The chemical formula for steam is H2O(g)
mass of steam = mole of steam * molar mass of H2O
= 1 * (1*2+16) = 18 g
by E = m * c * change in temperature,
From 140C steam to 100C steam
18 * 2.01 * (140-100) = 1447.2J
latent heat of vaporization of water = 2.26x10^6 J/kg* 0.018 = 40680 J
From 100C water to 0C water
18 * 4.2 * (100-0) = 7560 J
latent heat of fusion of ice = 334 J/g * 18 g = 6012 J
From 0C ice to -45C ice
18 * 2.09 * (45-0)
= 1692.9 J
1447.2 + 40680 + 7560 + 6012 + 1692.9 = 57392.1 J
POH + pH = pKw
pOH + pH - pH = pKw - pH
pOH = pKw - pH.
The correct equation used to calculate pOH would be C. pOH = pKw - pH.
Answer:
Examples of ROS include peroxides, superoxide, hydroxyl radical, singlet oxygen, and alpha-oxygen.
