A reaction comprises a reactant and a product. It is said to be in equilibrium when the rates for the forward and reverse reactions are equal. Thus, option D is correct.
What is an equilibrium reaction?An equilibrium reaction is a thermodynamic condition where the reactants and the products are at a stable position even before and after the reaction. They remain fixed and do not vary with the addition of any catalyst.
In the equilibrium position, the reaction rate of the forward (product formation) and reverse (reactant formation) remains the same and is seen in the reversible reactions only.
The amount of the products and the reactant remains constant till the temperature is constant but may vary if the tempearture is varied.
Therefore, the rate of reverse and forward are equal in the equilibrium reaction.

What is the pressure inside a 2.0 L bottle filled with 0.25 mol of carbon dioxide gas at 25 °C?
Answers
Answer:
3.1atm
Explanation:
Given parameters:
Volume of gas = 2L
Number of moles = 0.25mol
Temperature = 25°C = 25 + 273 = 298K
Unknown:
Pressure of the gas = ?
Solution:
To solve this problem, we use the ideal gas equation.
This is given as;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
P = [tex]\frac{nRT}{V}[/tex]
Now insert the parameters and solve;
P = [tex]\frac{0.25 x 0.082 x 298}{2}[/tex] = 3.1atm

What is the Molecular mass of sodiumcholoride ?
Answers
Answer:
58.5g/mol
Explanation:
Given substance:
Sodium chloride = NaCl
Unknown:
Molecular mass = ?
Solution:
The molecular mass of a compound is the gram-formula mass or gram-molecular weight of the compound.
It is determined by adding its component atomic masses and then express in grams per mole;
Atomic mass of Na = 23g
Atomic mass of Cl = 35.5g
NaCl = 23 + 35.5 = 58.5g/mol

Answer:what are u asking to do?
Explanation:
1 mol of titanium,
Ti, is 47.88 g is that true?
Answers
Answer: True.
Explanation:
Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.

Which best explains why a scientist would share these details in a conference?
It tells the audience if the results support or contradict the hypothesis.
It tells the peers if the study is supported by mathematical models.
It informs the peers if the results are supported by other scientists.
It informs the audience if the study included controlled tests.
Answer:
It informs the audience if the study included controlled tests.
Explanation:
Usually, scientific conferences involve presentation of papers by scientists. These paper presentations are actually the sharing of details of the scientific research carried out by other scientists.
Presenting the materials and methods section of the a research project to a scientific conference informs the audience if the study included controlled tests.
The inclusion of controlled tests in a scientific study enhances the validity of the results obtained in the study.

The word gentle traces back to the Latin word gentlis, meaning “of the same clan,” and at first the world was used to describe people belonging to distinguished families, who were seen as courteous and noble. Nowadays you’re more likely to hear the word used to refer to things that are calm, moderate, and without harshness. The word is often applied to people, but it can be used more broadly to describe anything that is mild, such as "a gentle detergent" or "a gentle reminder."

A. dissolved in water
B. when melted
C. when conducting electricity
D. never
Answers
Answer:
A. when dissolved in water
Explanation:
Water is an extremely polar molecule, meaning it has a positive end a negative end. When an ionic compound is dissolved, the positive pole of water will be attracted to the negative ion and attach itself to it. The same goes for the positive ions. That's how water breaks down ionic compounds
Answer:
ions do separate in an ionic compound because there is the free flow of electrons in the oppositely charged ions and conducts electricity in an aqueous form
