Answer:
-0.93 °C
Explanation:
Hello,
The freezing-point depression is given by:
Whereas is the freezing temperature of the solution, is the freezing temperature of the pure solvent (0 °C since it is water), the Van't Hoff factor (1 since the solute is covalent), the solvent's freezing point depression point constant (in this case ) and the molality of the glucose.
As long as the unknown is , solving for it:
Best regards.
Answer:
It means like, cells are like the base for every living thing.
Explanation:
The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
HOPE THIS WAS HELPFUL!!!
A reservoir serves as a long term storage area for water or nutrients
You need the heat of fusion of ice to solve this problem. <span>the heat of fusion of water = 334 J/g </span><span>
the formula to solve for heat is </span>q = m·ΔH<span>f</span>
just plug the values
q= (50.0 g) (334 j/g)= 16700 joules or 16.7 Kj
Complex a: <span>tetrachlorocuprate(i)
In present complex chlorine is negatively charged ligand (-1) and oxidation state of copper is +1. Therefore, total charge on complex = 4(-1) + 1 = -3
Complex b: </span><span>pentaamminechlorocobalt(iii)
In present complex, ammine is a neutral ligand (charge = 0), chlorine is negatively charged ligand (charge = -1) and oxidation state of Co is +3. Therefore, total charge on complex is 5(0) + (-1) + (+3) = +2
</span><span>Complex c: diaquadichloroethylenediaminecobalt(iii)
</span>In present complex, aqua is a neutral ligand (charge = 0), chlorine is a negatively charged ligand (charge = -1), ethylenediamine is a neutral ligand (charge = 0) and oxidation state of cobalt is +3. Therefore, total charge on complex is 2(0) + 2(-1) + 2(0) + 3 = +1.
