Give me an example of a reaction adhesion
BalasHapusIn substance behavior, two phenomena are known, namely, adhesion and cohesion. As also understood, that substance is composed of particles. Among the particles there is an attraction (bonding style). The force is not only present in similar particles, but also in particles of different kinds. The proof is, the sugar particles are soluble in water. That is, in addition there is an attractive attraction between water particles and between sugar particles, there is also an attractive attraction between water and sugar particles. The attraction between the particles of a kind is called cohesion, while the inter-type attraction between the different species is called adhesion. The major difference between the two forces is that the surface form of the liquid is not flat, but the meniscus (concave or convex meniscus).
HapusIf we put water into a large-diameter container such as a bucket or basin, the shape of the water surface is flat. However, this is not so. This will be obvious if we put water into small diameter containers such as test tubes. If we pour water into a test tube smeared with oil, the shape of the water surface appears convex. Such forms are called convex meniscus. This happens because the cohesion between the water particles is greater than the adhesion between the water and oil particles. The same shape will also be seen if we pour mercury in a test tube.
If we pour water or oil into a test tube, the surface of the face is concave. This form is called concave meniscus. This is due to the adhesion between water or oil particles with glass greater than the cohesion between water or oil particles. This is what causes water and oil to wet the walls.
Whether the molality and molarity are the same, if not explain if it is explained
BalasHapusMolarity (M)
HapusIs a unit of concentration widely used, and is defined as the many moles of solute in 1 liter (1000 mL) of solution with unit M.
Formula : M = gram of solute/mr x 1000/gram solvent
molality (m)
Is a unit of concentration which denotes the number of moles of the substance present in 1000 grams of solvent with mol unit.
Formula : gram of solute/mr x 1000/ml of solution
Grams of solute, gram solvent, ml of solution
explain to me about how to make a calorimeter!
BalasHapusA calorimeter is a tool used to determine the energy that accumulates by measuring the temperature changes that occur or other thermal effect changes. A calorimeter is a tool used for experiments related to heat. The calorimeter is designed so that the heat transfer to the environment occurs to a minimum. Basically a calorimeter consists of two vessels separated by an air space. The inside vessel is made of shiny aluminum to reduce heat absorption by the vessel wall. A wooden lorry cover is a poor conductor to avoid much heat being lost. The calorimeter can be used to measure the heat of a substance.
HapusThe principle of simple calorimeter work is known by the name of mixed method, ie one sample of the substance is heated to high temperature measured using a thermometer, then placed cold water calorimeter. The heat loss in the sample will be received by water and calorimeter. By measuring the final temperature of the mixture, the type heat can be calculated. To show the occurrence of energy exchange phenomenon, in this experiment used schurholtz aircraft. The Schurholtz aircraft is based on the Black principle which states that the given caloric will be equal to the heat received if the system is in adiabatic condition. The working principle of this tool is to convert the mechanical energy of the rotation to the heating energy caused by the frictional effect during the cycle.
Add 50 mL of 1 M KOH solution to the beaker, then put 50 ml of HCl solution into another glass (measure the volume of the solution using a measuring cup).
2. Measure the temperature of the KOH solution and the HCl solution before reacting. The thermometer should be cleaned and dried before use to measure the temperature of different solutions.
3. Record the temperature of the two solutions, then calculate the average temperature between 1M KOH solution and 1M HCl solution as the starting temperature.
4. Insert the two solutions into the calorimeter, then the solution continues to stir and measure the temperature. Record the fixed temperature as the final temperature of the reaction. Arrange a thermometer, stirrer and Styrofoam glass together.
can you give me more vocabulary about stoichiometry ?
BalasHapusthank you
HapusMass = massa, Relative molecular mass = massa molekul relatif, Mol = mol, volume = volume, Molar = molar, number of particles = jumlah partikel
