Answer:

2

Explanation:

The unbalanced reaction is shown below as:-

Pb(NO_3)_2+NaCl\rightarrow PbCl_2+NaNO_3

On the left hand side,  

There is 1 lead atom and 2 nitrogen atoms and 6 oxygen atoms  and 1 sodium atom and 1 chlorine atom

On the right hand side,  

There is 1 lead atom and 2 chlorine atoms and 3 oxygen atoms  and 1 sodium atom

Thus,  

Right side, NaNO_3 must be multiplied by 2 so to balance nitrogen and oxygen.

Left side, NaCl is multiplied by 2 so to balance the whole reaction.

Thus, the balanced reaction is:-

Pb(NO_3)_2+2NaCl\rightarrow PbCl_2+2NaNO_3

<u>Coefficient of the sodium chloride in the balanced equation - 2</u>

CICLOS BIOGEOQUIMICOS: lugares en que encontramos el elemento del ciclo separando en bioticos y abioticos
scoundrel [369]

Answer:

Los ciclos biogeoquímicos son definidos como la circulación de los elementos químicos entre organismos biológicos (es decir, el factor biótico del ciclo), y componentes geológicos inorgánicos del sistema (factores abióticos). En el ciclo del agua, por ejemplo, este elemento se encuentra esparcido en los ríos y arroyos, como así también en la atmósfera, desde donde fluye como lluvia hasta el suelo y puede ser ingerida por organismos vivos terrestres y es utilizada para llevar a cabo diversas funciones celulares.

Explanation:  

Los ciclos biogeoquímicos establecen un vinculo entre los factores bióticos y abióticos del ecosistema, de modo que la energía puede fluir libremente a través de ambas partes del sistema. Los seres vivos necesitan diferentes elementos químicos para sobrevivir, los cuales forma parte de los ciclos biogeoquímicos. En los ciclos biogeoquímicos los elementos se conocen como 'nutrientes' (micro y macronutrientes). Estos elementos se encuentran esparcidos tanto en la corteza de la tierra como en la biósfera. Los nutrientes son indispensables porque de ellos depende de que la energía fluya entre el componente inorgánico y orgánico del ciclo. Por otra parte, los nutrientes también circulan dentro del ciclo entre componentes bióticos de la cadena trófica, con lo cual no sólo los nutrientes sino también la energía fluye entre organismos, desde aquellos más basales en el sistema tales como plantas (ecosistemas terrestres) o algas (marinos), hasta los niveles superiores representados por especies animales hervívoras y carnívoras de tales ecosistemas.

How is specific heat capacity related to a change in state of matter?
wlad13 [49]

The heat capacity or thermal capacity of a body is the quotient between the amount of heat energy transferred to a body or system in any process and the change in temperature it experiences. In a more rigorous form, it is the energy necessary to increase the temperature of a certain substance by one temperature unit. [1] It indicates the greater or lesser difficulty that said body presents in experiencing changes in temperature under the supply of heat. It can be interpreted as a measure of thermal inertia. It is an extensive property, since its magnitude depends not only on the substance but also on the amount of matter in the body or system; therefore, it is characteristic of a particular body or system. For example, the heat capacity of the water in an Olympic-size swimming pool will be greater than that of the water in a glass. In general, heat capacity also depends on temperature and pressure.

a given sample of a gas has a volume of 3.0 L at a pressure of 4.0 atm. If the temperature remains constant and the pressure is
pentagon [3]

Answer:-

2.0 L

Explanation:-

Initial Volume = V 1 = 3.0 L

Initial Pressure P 1 = 4.0 atm

New pressure P 2 = 6.0 atm

Using boyle's law

P1 V1 = P2 V2

New Volume V2 = P1 V1 / P2

= 4.0 atm x 3.0 L / 6.0 atm

= 2 .0 L

How much heat is released when 75 g of octane is burned completely if the enthalpy of combustion is -5,500 kJ/mol C8H18
AnnyKZ [126]
<span>Enthalpy change is the total heat that is absorbed or evolved in a certain reaction that is being carried in a constant pressure system. It can be calculated by the product of the specific heat of the substance and the difference of the final temperature and the initial temperature. For this case, the enthalpy of combustion is given, so we simply multiply the amount of octane present to the enthalpy given to determine the total heat that is released. 

Heat = 75 g ( 1 mol / 114.23 g ) (- 5500 kJ / mol ) = - 3611.14 kJ

The negative sign in the calculated value represents that this heat is being released in the process.</span>
