Answer:
Electrones de valencia.
Explanation:
¡Hola!
En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.
¡Saludos!
Answer:
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
Explanation:
Specific heat capacity of paraffin, Cp = 2.90 J/g.°C = 2900 J/kg.°C
Specific heat capacity of water = 4.20 J/g.°C = 4200 J/kg.°C
Amount of heat energy that can be stored by 4.73 * 10³ kg of water heated through a degree rise in temperature can be calculated as below:
Using H = mCpθ where m is mass of substance, Cp is specific heat capacity and θ is temperature change
H = 4.73 * 10³ kg * 4200 J/kg.°C * 1°C
H = 19866000 J
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10 3 kg of water for a degree rise in temperature is calculated as follows:
H = mCpθ
19866000J = m * 2900 J/kg.°C * 1°C
m = 19866000J / 2900 J/kg
m = 6850.34 kg = 6.85 * 10³ kg
Therefore, mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
Answer:
ELECTRONEGATIVITY is the tendency of an atom in the molecule to attract the bonded pair of electrons .
Explanation:
it might help you!!!!!!
Answer:
That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
The "Imported Asset" refers to the image attached to this answer. And this is a true or false question regarding whether the structure shown is a cyclohexane ring containing two attached methyl groups.
The correct answer is
TRUE. The ring structure is composed of 6 carbons which makes it a cyclohexane, and there are two methyl groups (-CH3) attached to the ring in the 1- and 3-positions of the ring. The full name of this structure is 1,3-dimethylcyclohexane.
