Answer:
The lithium bromide salt is a neutral salt that when reacted with water, it can dissolve and form a supersaturated, balanced or slightly saturated solution.
If we increase the temperature of said reaction, we promote the dissociation of the molecules, thus helping to dissolve, in this way the solution would form much faster than at 60 degrees Celsius.
Explanation:
As this chemical compound is a neutral salt, we mean that its pH is neutral.
Binary salts are combinations of 2 elements other than hydrogen and oxygen. The union of a metallic element with a non-metallic element forms a neutral salt, while the union of a non-metallic element with another non-metallic element forms a volatile salt.
The types of neutral salts that exist are: fluorides, chlorides, bromides, iodides, astatides, sulfides, tellurides, selenides, nitrides, phosphides, arsenides, antimonides, borides, carbides and silicides.
The torque on the lever, with a 15 N force applied perpendicular at 2.0 m from the pivot point, is 30 N·m.
The torque on a lever is calculated by the formula T = rF sin θ, where T is torque, r is the distance from the pivot point to the point where the force is applied (lever arm), F is the force applied, and θ is the angle between the lever arm and the direction of the force. In this case, the force is applied at 90° to the lever arm, so the sin θ part of the formula is equal to 1. Therefore, the torque can be calculated by multiplying the force by the lever arm distance. With a force of 15 N applied perpendicular to the lever arm at a distance of 2.0 m from the pivot point, the torque on the lever would be 30 N·m (15 N x 2.0 m).

Pure substance can be any element or compound and is formed from one type of atom/molecule only
Meanwhile, the solution is included in a mixture consisting of 2 or more pure substance
Pure substance can be formed through a chemical process while the mixture is through a physical process
Mixture can be separated by physical processes into components of pure substance while pure substance cannot
The mixture itself consists of a homogeneous and heterogeneous solution
The mixture can be divided into a homogeneous mixture if the composition/ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.
Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles
Homogeneous mixture = Solution
Heterogeneous mixture = suspension, and
The mixture is located between suspension and solution = Colloid
