choose the correct one
Answer:
B. More reactant is added.
Explanation:
The question basically asks at which condition would the forward reaction be favoured.
The law of equilibrium states when a system at equilibrium is disturbed by, it would annul that change. In order to increase the forward reaction, more of the reactant should be added. In order to annul this change, the system would have to favour the reaction that deals with reducing the amount of reactant added.
The correct option is;
B. More reactant is added.

What is the diameter of Neptune in standard notation and scientific notion?
Answer:
Standard notation: 49,244 km
Scientific notation: 4.92x10⁴ km
Explanation:
The diameter of Neptune in standard notation is:
49,244 km
In the standard notation, we write the result in a normal way.
Now, to express the diameter in scientific notation we need to use a base ten power as follows:
4.92x10⁴ km
In the above result, the positive exponent indicates that the number is larger. The decimal point is located near the first digit.
Therefore, the diameter of Neptune in standard notation is 49,244 km and in scientific notation is 4.92x10⁴ km.
I hope it helps you!

Which of the following pairs of elements will combine to produce a covalent bond?
1-Hydrogen and chlorine
2-Magnesium and oxygen
3-Lithium and bromine
Answer:
Hydrogen and Chlorine
ie HCL
The pairs of chemical elements that will combine to produce a covalent bond is: 1. Hydrogen and chlorine.
In Chemistry, the three (3) main types of chemical bonds include:
Ionic bonds: Lithium and bromineHydrogen bonds: Hydrogen and oxygen.Covalent bonds: Hydrogen and chlorine.A covalent bond can be defined as a type of bond that typically involves the sharing of electrons between the atoms of a chemical element.
For example, the type of bond that is produced (formed) between hydrogen atoms and a chlorine atom is a covalent bond.
The hydrogen atom shares it single electron with a chlorine atom that is having seven (7) valence electrons to produce an inert gas such as hydrochloric acid (HCL).
In conclusion, the pairs of chemical elements that will combine to produce a covalent bond is hydrogen and chlorine.

How much heat energy is absorbed when 94.0 g of water is heated from 5.0C to 29.5C? Show your work.
Answer:
In order to be able to solve this problem, you will need to know the value of water's specific heat, which is listed as
c=4.18Jg∘C
Now, let's assume that you don't know the equation that allows you to plug in your values and find how much heat would be needed to heat that much water by that many degrees Celsius.
Take a look at the specific heat of water. As you know, a substance's specific heat tells you how much heat is needed in order to increase the temperature of 1 g of that substance by 1∘C.
In water's case, you need to provide 4.18 J of heat per gram of water to increase its temperature by 1∘C.
What if you wanted to increase the temperature of 1 g of water by 2∘C ?
This will account for increasing the temperature of the first gram of the sample by n∘C, of the the second gramby n∘C, of the third gram by n∘C, and so on until you reach m grams of water.
And there you have it. The equation that describes all this will thus be
q=m⋅c⋅ΔT , where
q - heat absorbed
m - the mass of the sample
c - the specific heat of the substance
ΔT - the change in temperature, defined as final temperature minus initial temperature
In your case, you will have
q=100.0g⋅4.18Jg∘C⋅(50.0−25.0)∘C
q=10,450 J
