Answer:

<u><em>=355.5K</em></u>

Explanation:

Specific heat, Q = mcΔT

where

  • Q= 4250J
  • ΔT= change in temp = final temp - initial temp
  • c = specific heat capacity = 1.7
  • m = mass of substance in grams

[1 mole of Ne = 20g; 2 moles of Ne = 2 × 20 = 40g]

4250 = 40 × 1.7 × (final - 293K)

final - 293k = 4250 / ( 40 × 1.7)

Final temp = 62.5 + 293

<em>=355.5K</em>

I hope this steps are simple to follow and understand.

Use the atom builder interactive to identify each nucleus. Two protons represented as purple spheres and one neutron represented
aleksandr82 [10.1K]

Answer:

\frac{3}{2}He

\frac{6}{2} He

\frac{7}{4}Be

\frac{3}{1} H

\frac{6}{4}Be

\frac{7}{3} Li

Explanation:

In the first nucleus we are told that there are two protons and one neutron. Let us remember that the mass number = number of protons + number of neutrons.

This implies that, for the first specie the mass number is 3, for the second specie the mass number is 6 and the third specie has a mass number of 7 and so on. The mass number is indicated as a superscript.

The atomic number is the number of protons in the nucleus of the atom and helps us to identify the atom. It is always written as a subscript as shown.

How does fermentation allow the cell to continue to make atp when oxygen is not present?
kap26 [50]

Explanation:

Usually most cells that carry anaerobic respiration utilize the Glycolysis pathway because it does not require oxygen. It is also believed it is the ancient metabolic pathway by utilized by primordial cells  when the earth's atmosphere was not mainly oxygen,  

Glycolysis consumes 2 ATPs (during the conversion of Glucose to Fructose 1,6 bisphosphate ) but produces a gross $ ATPs. It, therefore, has a net ATP of 2. This is inefficient when compared to the Krebs cycle that utilizes oxygen to produce 34 ATPs. Anaerobic respiration produces pyruvate. This pyruvate is broken down into an organic acid like lactic acid which is excreted from the cell, which is why fermented food tastes sour.

Beer's Law states that A=ebc, where A is the absorbance, ε is the molar absorptivity of the solute, b is the path length, and c
Gelneren [198K]

Answer:

b. changing the compound changes the absorbance behavior.

Explanation:

  • Option a) would be akin to modifying the <em>path length</em>, b.
  • Option b) would involve using a different solute, as such, there would be another <em>molar absortivity</em>, ε.
  • Option c) would decrease the<em> concentration</em> (c) of the solute, which would explain why the absorbance would decrease as well.
