Answer:
Esto se debe a que la heladera tiene mucha menor temperatura que la temperatura ambiente.
Esta menor temperatura ayuda a luchar contra los microorganismos que están en los alimentos (bacterias, hongos, etc) pues detiene en gran medida su repreduccion, la cual se ve maximizada en los rangos entre 5°C y 60°C, tal que la temperatura ambiente suele estar en el rango donde los microorganismos prosperan y se reproducen, es por ello que los alimentos se conservan mucho mejor en ambientes fríos (como la nevera) que en temperatura ambiente.
The number of boxes is calculated by dividing the
total mass of hardware boxes by 1.00 kg
<h3>What is a hardware?</h3>
A hardware is a physical component of a system that can be touched and felt.
Because hardware are physical components, they always have a given mass.
Assuming, several hardware each of mass 1.00 kg is available to be chosen from.
Also, assuming that the sum total of the mass of all the hardware is known.
The number of boxes can be calculated as follows:
- total mass of hardware/1.00 kg
Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.

<span>N2H4 is a polar molecule </span>
Answer:
A buffer solution is a mixture of two pair salts to maintain a stable pH.
Explanation:
This mixture is made always with a complementary pair of salts (one acid an another basic).
Example:
Acetic Acid (CH3COOH) and Sodium Acetate (NaH3COO).
So when you add a little bit more acid to this mixture, the basic part of the buffer, in this case the Sodium Acetate, will neutralize it and the pH will remain the same.
On the other hand, if the mixture receives some basic substance, the acid part of the buffer, the acetic acid, will neutralize it, so again the pH will remain the same.
<span>Fischer projection for D-2-ketotetrose is in Word document below.
</span>D-2-ketotetrose is monosaccharide, having both a ketone (a ketose) and four carbons (a tetrose). There are two ketotetroses (the enantiomers) L and D-erythrulose, this is D-erytrhrulose (1,3,4-trihydroxy-2-butanone).
