Water is unusual because it expands as it freezes, Very few substances have this property. The reason liquid water is more dense
Ymorist [56]

Answer:

When liquid water is cooled, it contracts until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%. When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

dolphi86 [110]

Answer:

Separated

Explanation:

Stan does not feel he identifies closely with the group. He feels the other members are close knit with each other but he is not part of the group.

For Stan, it would be an illusion to say he has a close relationship with the members of the group

This infers that Stan has a separated self-schema with respect to the group.

A sample of calcium carbonate weighs 2.1 kilograms (kg). There are 1,000 grams (g) in 1 kg, and 1 Times. 109 nanograms (ng) in 1
TiliK225 [7]

Answer:

2.1 x 10¹²ng

Explanation:

Mass of the calcium carbonate given is:

                    2.1kg  

We need to take this mass to nanogram, ng.

Since :

               1000g  = 1kg

           10⁹g  = 1ng

So;

          1kg  = 1000 x 10⁹ = 10¹²ng

So;

      2.1kg   will give;

                Since

              1kg  gives 10¹²ng

             2.1kg will give 2.1 x 10¹²ng

The value of ΔG°′ for the conversion of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate (GAP) is +7.53 kJ/mol . If the
OverLord2011 [107]

Answer:

Concentration of  glyceraldehyde-3-phosphate is 0.0886mM

Explanation:

Get K from the expression exp(ΔG/-RT) = K

Where  

ΔG = Gibbs free energy = 7.53 kJ/ mol = 7.53 * 10^3 J/mol

T = 250C = 273 +25 = 298 K

R = 8.3145 J(mol.K)

K = exp(7530/(-298*8.3145)

K = 4.79*10^-2

NB: K = (conc of products)/(conc of reactants)

From the question

dihydroxyacetone phosphate is the reactant while glyceraldehyde-3-phosphate is the product

4.70*10^-2 = (conc. Of products/1.85mM)

Conc of products = (4.70*10^-2)*1.85

Conc. Of products = 0.0886mM
