What is the most likely reason that nonmetals are electrical insulators

Chemistry
2 answers:
Luba_88 [7]3 years ago
8 0

Answer:

Non metals are poor conductors of electricity as they have no free electrons in the outer most shell.

The poor conductors of the electricity is best to be used as insulators. These insulators can be used to protect the person from electrical shocks.

The valence shells in case of non metals are almost full, the atoms attracts the electrons and hold them tight and there is no electron left free to conduct electricity.

Hence, non metals are used as insulators.

Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.

A metabolic pathway that ___ (oxidizes or reduces) an energy-rich source to produce ATP from ADP. Electrons are transferred from
OlgaM077 [116]

Answer:

see explaination

Explanation:

1. A metabolic pathway that OXIDIZES an energy-rich source to produce ATP from ADP.

Oxidation reactions are exergonic and can be coupled to produce ATP from ADP + Pi

2. Electrons are transferred from electron DONORS to compounds with a STRONGER reduction potential.

Electrons are moved from compounds with low reduction potential to compounds with high reduction potential.

3. As electrons move through the electron transport chain, ETC, the energy in the electron is used to pump PROTONS across a membrane.

In respiration, protons are pumped from the mitochondrial matrix to the perimitochondrial space.

4. The pumping of these molecules against their concentration gradient is a form of FACILITATED transport.

Since protons are charged particles, they require a carrier protein for their transport. The movement of these molecules back into the cell (down their concentration gradient) releases energy which the cell couples to the formation of ATP.

6. The energy in PHOTON/LIGHT is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC.

7. The ETC creates A PROTON GRADIENT which is used by the cell to power the formation of ATP.

8. In CYCLIC ELECTRON TRANSPORT, the electron returns to the photocenter.

9. In NON-CYCLIC photosynthesis the electron reduces NADP+ to form NADPH.

How much concentrated 18M sulfuric acid is needed to prepare 250mL of a 6.0M solution?
slavikrds [6]
C₁ * V₁ = C₂ * V₂ 

18 * V₁ = 6.0 * 250

18 V₁ = 1500

V₁ = 1500 / 18

V₁ = 83.33 mL

hope this helps!

How are plate tectonics and the rock cycle connected
mote1985 [20]

Answer:

All igneous rocks the basis of the rock cycle are formed by plate tectonics. ... The heat from the mantle that fuels plate tectonics causes both igneous and sedimentary rocks to be turned into metamorphic rocks. The metamorphic rocks can be eroded into sedimentary rocks are remelted back into igneous.
