Define diffusion. Is it faster in summer or winter season?

2 answers:

6 0

Diffusion is the process of a substance spreading out to evenly fill its container or environment. Kinetic energy of particles of matter increases with an increase in temperature. More the kinetic energy in the particles, more is the rate of diffusion. so diffusion is faster in the summer!

hope this helps!

How many grams of Zn are there in a sample of Zn that contains the same number of moles as a 82.1 gram sample of Ga? grams of Zn

SVEN [57.7K]

Answer:

mass of Zn = 77.0 g

Explanation:

In the sample you have the same moles of Zn and Ga.

The formula for moles is:

$Mass = moles*MM \\$

Where MM: Molar Mass or Atomic Mass for elements

AM(Ga) = 69.723 amu

AM(Zn) = 65.38 amu

moles of Ga = $\frac{Mass}{AM} = \frac{82.1 g}{69.723 amu} = 1.178 mole$

mass of Zn = $moles*AM=1.178 mole*65.38amu = 77.0 g$

Compare the entry-level substrates, products, and metabolic purposes of glycolysis and gluconeogenesis.

mixas84 [53]

Glycolysis is the process by which glucose molecules are broken down to pyruvate molecules while gluconeogenesis is the process by which glucose is synthesized from non-carbohydrate molecules. For glycolysis, the entry level substrate is glucose, the product is pyruvate and energy in form of ATP and the metabolic purpose of glycolysis is energy production. For gluconeogenesis, the entry level substrate can be lactate, pyruvate, glycerol or glucogenic amino acid, the product is glucose and the purpose of the process is generation of glucose.

For the reaction below, Kp = 1.59 at 100°C. If 1.0 g of SrCO3 is placed in an empty 5.00 L reactor and allowed to reach equilibr

Sergio [31]

Answer:

$p_{CO_2}^{eq}=1.59atm$

Explanation:

Hello, in this case, one could consider the undergoing chemical reaction as:

$SrCO_3(s)\rightleftharpoons SrO(s)+CO_2(g)$

Thus, since 1.0 g of strontium carbonate is placed, the equilibrium equation takes the following form, excluding the solid-stated species and considering just the carbon dioxide as it is gaseous:

$Kp=p_{CO_2}^{eq}=1.59atm$

Hence, since at the beginning there is no carbon dioxide, its pressure at equilibrium equals Kp:

$Kp=p_{CO_2}^{eq}=1.59atm$

Which was clearly defined above.

Best regards.
