I'm pretty sure that you multiply the number of moles by avogadro's number (6.02x10^23)... you may want to check.

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.

A ball with a density of 1100 kg/m3 is submerged in two liquids: water (ρ = 1000 kg/m3) and honey (ρ = 1400 kg/m3). What will th
Lapatulllka [165]

Hello!

So, we are given a ball with a density of 1100 kg/m³, and two liquids: water (1000 kg/m³) and honey (1400 kg/m³). Our goal is to determine if the ball will sink or float in the given liquids.

Let's take two common substances: water and ice. Water has a density of 1000 kg/m³ and ice has a density of about 917 kg/m³. You would notice that the ice is always floating when you put ice and water together. This would occur if you have other substances.

Here's what you should know:

  1. If the density of an object is greater than the liquid it is in, then that object will sink.
  2. If the density of an object is less than the liquid it is in, then that object will float.

Since the ball has a density of 1100 kg/m³, and water's density is 1000 kg/m³, then the ball will sink. If the ball is placed in honey, then it will float because the density of honey (1400 kg/m³) is greater than the ball's density.

Therefore, objects with a greater density than the surrounding liquid sink, while objects with a smaller density than the surrounding liquid float, which is the fourth choice.

What type of compound is fe3n2
Shkiper50 [21]

Fe3N2, also known as Iron (II) nitride, is an ionic compound.


Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.


Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.
