Explanation: In solids, particles are very closely packed in an orderly arrangement in a lattice and only vibrate in fixed positions. The forces of attraction between them are very strong. This allows them to overcome the forces of attraction that hold the other phases closer together

TRUE OR FALSE
The statement is a false.
An acid is a substance which when dissolved in water, produces hydroxonium ion, as the only positive ion.
Some properties of acid include:
They have sour tastes andStrong acids are corrosive.There are two types of acids which includes:
Strong acids: These are the acids that ionizes completely in solution.Weak acid: These are the acids that ionizes incompletely in solution.Examples of weak acid is acetic acid and tartaric acid.
They can be used as food substances like vinegar and naturally occurs on fruit like banana or grape.
Therefore, weak acids such as acetic acid and tartaric acid can be tasted.

The given statement is False.
Some acids like acetic acid and tartaric acid can be tasted.
Organic acids, such as acetic, citric, malic, and fumaric acids in fruits and vegetables, and tartaric acid in wine, contribute significantly to the sour flavor of foods and beverages. Many inorganic acids taste sour in dilute solutions.
Tartaric acid is fairly water soluble and has a pronounced tart flavor. Tartaric acid is present naturally in grapes and bananas and has been shown to improve the flavor of grape and lime-flavored beverages. Tartaric acid may aid in the treatment of glucose intolerance and digestion.
Acetic acid is a colorless liquid having a sour flavor. Although it is most frequently associated with vinegar, this acid has a wide range of different applications in a variety of industries. Acetic acid is a colorless liquid that is composed of chemical compounds.

how does the value of g on the earth is related to the mass of the earth and its radius drive it
The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].
What is weight of an object?
The weight of an object is determined as the product of the object's mass and acceleration due to gravity.
F = mg
The gravitational force on objects in the universeThe gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.
[tex]F = \frac{GmM}{R^2} [/tex]
[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]
where;
M is the mass of the earth
R is the radius of the earth
Thus, the relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

1. One atom contains 29 protons and 34 neutrons. Another atom of the same element has a mass number of 65. How many protons and neutrons does this unknown atom have?
A. 28 protons, 37 neutrons
b. 29 protons, 36 neutrons
C. 29 protons, 35 neutrons
D. 31 protons, 34 neutrons
Answer:
b
Explanation:
because its the atom of the same element, the no of protons doesn't change but the mass number changes so we can find the mass number by:
(mass number = atomic no/no of protons + no of neutrons)
here;
mass number given = 65
and we know, no of protons = 29
let no of neutrons = x
hence,
65 = 29 + x
x= 65 – 29
x= 36
hence your answer is b

If you run a refrigerator in a closed room with the refrigerator door open,the room temperature willA) increase.B) decrease.C) remain unchanged.
Answer: A increase
Explanation: The temperature of room will increase. If a refrigerator door is open then more flow rate of coolant is required in order to maintain lower temperature So the compressor will be running continuously also heat exchange happening through condenser increases the room temperature rather than decreasing.

Which part of atomic structure is responsible for the reactivity of atoms?
The electrons present in the valence shell of an atom are responsible for the reactivity of atoms.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

How many moles of AgCl can form from 6.5 moles of Ag and abundant HCl in the equation: 2Ag + 2HCl -> 2AgCl + H2
6.5 moles of AgCl can be formed from 6.5 moles of Ag.
STOICHIOMETRY:
According to this question, silver reacts with hydrochloric acid to form silver chloride and hydrogen gas as follows:
2Ag + 2HCl → 2AgCl + H2
Based on this balanced equation, 2 moles of silver (Ag) produces 2 moles of silver chloride (AgCl).
This means that 6.5 moles of Ag will produce (6.5 × 2)/2 = 6.5 moles of AgCl.

Explanation:
The plasma membrane is a structure that has several distinct roles in the cell
The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic
*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:
when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids
*Protein Molecules play an important role in transport system such as Carrier Proteins
