Answer:

autotrofas estrictas son aquellas bacterias incapaces de crecer usando materia orgánica como fuente de carbono. Mixotrofas son aquellas bacterias con metabolismo energético litotrofo (obtienen energía de compuestos inorgánicos), pero requieren sustancias orgánicas como nutrientes para su metabolismo biosintético.

Explain the conductivity results observed for sodium chloride in the solid state and in aqueous solution
Fittoniya [83]

NaCl when in solid state does not conduct electricity while it does in aqueous solution.

Explanation:

NaCl (or what we call common salt) first needs to be either melted or dissolved in a solution for it to conduct electricity. The reason for this is that electrons in a solid state does not have enough freedom to move to either the Cathode (-ve) or to the Anode (+ve). So in a liquid state the electrons are now free enough to move.

Base your answer on the information below. The hydrocarbon 2-methylpropane reacts with iodine as represented by the balanced equ
Kryger [21]

Answer:

See explanation

Explanation:

The boiling point of a substance is affected by the nature of bonding in the molecule as well as the nature of intermolecular forces between molecules of the substance.

2-methylpropane has only pure covalent and nonpolar C-C and C-H bonds. As a result of this, the molecule is nonpolar and the only intermolecular forces present are weak dispersion forces. Therefore, 2-methylpropane has a very low boiling point.

As for 2-iodo-2-methylpropane, there is a polar C-I bond. This now implies that the intermolecular forces present are both dispersion forces and dipole interaction. As a result of the presence of stronger dipole interaction between 2-iodo-2-methylpropane molecules, the compound has a higher boiling point than  2-methylpropane.

A fixed quantity of gas at 21 °c exhibits a pressure of 752 torr and occupies a volume of 5.12 l. (a) calculate the volume the g
mariarad [96]
A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L

B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L


Hoped this helped ( I believe it's right, sorry if it's not )
