a reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken.
Answers
Answer:
Exothermic
Explanation:
Bond strength has everything to do with the energy associated with it. What I mean by that, is a stronger bond will require a lot higher of an energy input to break than a weaker bond.
In the same way, energy is released when a bond is made. So, the formation of a stronger bond releases more energy than the formation of a weaker bond.
So, putting the two ideas together, if the bonds formed as stronger than the bonds broken, then more energy is released than taken in, which means energy is released overall over the course of the reaction. This means that the reaction is exothermic.
If there was energy taken in overall, this would be an endothermic reaction.
Let me know if that makes sense, and hope I helped! :)
Exothermic reaction is a reaction in which the bonds formed during the reaction are stronger than the bonds broken.
When chemical reactions occur, there will always be an accompanying energy change.
In exothermic reaction the bonds formed in the products are stronger than the bonds broken in the reactants whereas in endothermic reaction the bonds broken in the reactants are stronger than the bonds formed in the products.

1. The equation representing the equation is ~
[tex] \mathrm{Na + Cl\rightarrow NaCl}[/tex]
The given reaction is a redox reaction because there's a transfer of electron from Sodium (Na) to chlorine (Cl)
where sodium is oxidized (due to loss of electron) and chlorine get reduced (due to gain of electron).
2. Sodium is a highly reactive element which belongs to the 1st group of periodic table, hence it can catch fire if it is kept free in atmosphere. so in order to prevent that it is stored in kerosene oil, which doesn't let Sodium come in contact with air .

Calcular el valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17° C.
Answers
El valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17°C es 47.56 atmósferas.
La presión osmótica se puede calcular usando la siguiente ecuación:
[tex] \pi = \frac{nRT}{V} [/tex] (1)
En donde:
n: es el número de moles = 2 moles
R: es la constante de los gases = 0.082 L*atm/(K*mol)
T: es la temperatura = 17 °C = 290 K
V: es el volumen = 1 L
Introduciendo lo valores anteriores en la ecuación (1), tenemos:
[tex] \pi = \frac{nRT}{V} = \frac{2 moles*0.082 L*atm/(K*mol)*290 K}{1 L} = 47.56 atm [/tex]
Por lo tanto, la presión osmótica es 47.56 atmósferas.

the atomic # of both is 6, so they are both carbon with 6 protons
element 1 has a total of protons plus neutrons of 12, element 2 of 13
so element 1 has 6 neutrons,element 2 has 7
element 2 has a +1 charge with 6 protons, so it has only 5 negative electrons
element 1 with 6 protons has 6 electrons, so it has a 0 charge

Answers
Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.
Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.
In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.
This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.

The volume of a balloon is 30 L at 313K and a pressure of 153KPA What is the volume at 273K and 101.3kPa?
from PV=nRT we can derive
PV/T =P'V'/T' so
153X30/313 = 101.3 X V'/273
OR 153 X 30 X273/(313 X 101.3) =V'
V' = 39.5 L
What is the most abundant type of protein in egg white? What do you think its purpose is?
Answers
Answer: Ovalbumin (Albumin)
Explanation:
The albumen (egg white) is composed of almost 60% of the protein ovalbumin. It's the main source of proteins for tissue synthesis in the embryo. It acts as a storage protein, storing ions and amino acids necessary for embryonic development.
There are four different proteins present in egg white. In which the most abundant protein is ovalbumin present in 54 %.
What are proteins?Proteins are biomolecules very essential for life. Proteins are made of a number of amino acids. Amino acids join together to form peptides and large number of peptides constitute a protein.
Essential amino acids have to be up taken from diet and non-essential will be produced inside the body.
Proteins are the major substances to build up our body. There are essential and non essential amino acids. Nails and hair are made of keratin protein. Milk contains the protein called lactine.
Similarly the protein in curd is casein. The proteins in egg white are ovalbumin, ovotransferrin, ovomucin and ovomucoid. In which ovalbumin is most abundant.
