Answer:
<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>
Explanation:
In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.
NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.
Did you know conventional argult culture has increased greenhouse gas emissions, soil erosion, water pollution, and threatened humans health. Let’s stop this from harming our environment and take action about this today. Organic farming has a smaller carbon footprint, conserves and builds soil, replenishes natural ecosystems for cleaner water and air, all with a toxic pesticide residues.
Answer:
A
Explanation:
With chemical reactions, there are various factors that affect the rate of the reaction. One of these is temperature.
When you raise the temperature, the reaction will move faster. Why? Temperature is directly correlated with the kinetic energy (basically, the energy that makes the particles move). Higher temperatures mean higher kinetic energies. Particles with higher kinetic energies move faster, which makes them more likely to collide. When collisions occur more frequently, the reaction follows through more quickly.
Thus, when Julissa warms the solutions, she will see that bubbling and white solid formation (the products of the reaction) occus faster. So, the answer is A.
Hope this helps!
Answer:
The population of the long-legged birds decreases.
Explanation:
The population of the short-legged birds increases whereas the population of long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.
Answer:
Atoms bind because, being united, they acquire a more stable situation than when they were separated and this allows them to exist in nature. This situation of greater stability usually occurs when the number of electrons that possess the atoms in their last level is equal to eight, structure that coincides with that of the noble gases.
Quemical bonding refers to the attraction forces that keep bonded the atoms in compounds, and there are two main types of chemical bonding: ionic and covalent bonding.
Explanation:
1)<u> Ionic bond:</u> results of the electrostatic interaction between ions, that results in the net transfer of one or more electrons from one atoms or group of atoms to other atom.
<em><u>Example of ionic bond:</u></em>
Sodium Chloride Na-Cl +, Sodium ion has a positive charge and chlorine ion has a negative charge, so chlorine seats an electron to sodium creating a ionic bond.
2)<u> Covalent bond:</u> In this type of chemical bond two atoms shares one or more pairs of electrons.
<em><u>Example of covalent bond</u></em>
Carbon monoxide is an example of a compound that has covalent bond, one carbon atom and one oxygen atom, linked by a triple bond that consists of two covalent bonds as well as one dative covalent bond.
