electrons are transferred in a oxidation-reduction reaction
oxidation reduction chemical equation involve electrons transfer between two species. In this reduction-oxidation type of chemical equation oxidation number of molecule, atoms or ion changes by gaining or losing electrons,that is there an oxidizing agent and a reducing agent in the reaction.
The best answer is (2) <span>stronger attraction for electrons, for the fluorine atom has a higher electronegativity than the carbon one, if not highest of all nonmetals.
Hope this helps~</span>
Answer:
Protons are positively charged. The mass is slightly lower than a neutron.The location of a proton is nucleus. The the role of a proton is to help bind the nucleus together.
Explanation:
Answer: Q= -34.6 J
Explanation: Use Q= mc∆T
c for solid lead is equal to 0.159 J/g°C
Substitute the values:
=14.8 g(0.159J/g°C)(23.7°C-38.4 °C)
= 14.8 g(0.159J/g°C) ( -14.7°C)
= -34.6 J
Cancel out the following units: g and °C so the remaining unit is in J.
The correct option is A.
In the convection cell, cold air sinks at the poles because of their high pressure. As the air moves away from the poles along the earth surface, it begins to get warm and its pressure reduces. Convection cells are circular pattern of wind which are caused by the rising and sinking of wind.
