To solve this problem remember one thing: the volume will remain constant because the gas is placed in a steel tank. The formula you need to follow is: P1/T1 = P2/T2. Input all of the needed details and you will reach the answer 84.59 Degrees Celsius which is letter C in the choices. The gas pressure will increase because of kinetic energy.
When the molecules are required to move, they would try their best to move around to supposedly get out of the container. Since they are confined to the container however, they would keep on bumping around. As they continue moving, the pressure will start to increase. There are moments when they bump around so much that the enclosed container succumbs to the pressure and blows up.
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
The correct answer to this question is A. A solution is a mixture made up of at least substances, and usually it is hard to separate the two after the solution is mixed. A solution is two components: a solvent and a solute.
The solvent is the mixture that makes up the majority of the solution and is the component that dissolves the other substance(s). The solute is the component that is introduced. Water is a common solvent. In this question, the sugar is introduced to the iced tea, making sugar the solute and the iced tea the solvent.
Electrons, protons, and neutrons are the three fundamental particles in an atom. Electron is a negatively charged particle, and according to Dalton's Atomic Theory, electrons are found outside the nucleus, and they orbit the nucleus. Protons, on the other hand, are positively charged particles found inside the nucleus of an atom together with neutrons. Protons consist of other simpler particles, while electrons do not consist of other simpler particles. Since both protons and neutrons have opposite charges, electrons will always revolve around the nucleus in a bid to get attracted to a proton.
And since the number of electrons in an atom is equal to the number of protons, therefore, we have a neutral atom. Electron is usually represented with the symbol e-, while a proton is represented with the symbol p+. The relative mass of an electron is 0.00055, whereas the relative mass of a proton is 1. The atomic number of an atom can be calculated by knowing the number of particles or protons in a molecule.
H-F is the most ionic out of all the choices available. This is because when the differences are computed, this has the greatest electronegativity difference. Take note that only those with differences that are 1.7 and higher are considered to be ionic.
A perfect ionic bond needs to have 100% ionic bond character. A covalent bond is the opposite of an ionic bond. Covalent bonds usually involve the sharing of different electron pairs. Usually, it is the electrons that are shared/arranged between the different atoms.
The ‘‘Molarity’’ and ‘‘Molality’’ are measures of the concentration of a chemical solution. Molarity is also referred to as Molar concentration, and Molality is also referred to as Molal concentration. The following are the significant differences between Molarity and Molality: a. DEFINITION: Molarity is the ratio of moles of a substance (Solute) to the volume of the solution (mol/L) while Molality is the ratio of moles to the mass of the solvent (mol/kg). b. SYMBOL:
Solutions labeled with the Molar concentration are denoted with a capital case ‘‘M’’ while solutions labeled with the Molal concentration are denoted with a lower case ‘‘m’’. c. PRECISION: Molarity may result in an imprecise and inaccurate concentration, while molality results in an accurate, precise measurement of concentration. d. FACTORS: Molarity is usually affected by the changes in pressure and temperature that occurs in the volume of solvent while Molality is generally unaffected by the changes in pressure and temperature since it is calculated based on mass and not volume.
For those who do not know, the HG20 and the HG21 are two types of video cameras that are created by Canon. The HG21 is the updated version of HG20. All of the weaknesses of the HG20 are improved for the HG21. One of the most obvious differences is the change from the simple LCD to the multi-angle vivid person.
This means that you can have a better viewing angle as compared to the HG20. Another difference between the two is the larger hard drive. This means that you can film more videos for a longer period of time. Just one thing that people like about the HG20 is that it is lighter as compared to the HG21.
Ampicillin and Amoxicillin are two types of antibiotics with almost similar composition. Both Ampicillin and Amoxicillin are very much available in the market. Both drugs help in combating the activities of harmful bacteria in the body. Amoxicillin is like a generic name for drugs like Amoxil, Alphamox, and Dispermox. All these brands of Amoxicillin are used in the treatment of bacterial infections, and they are very effective in treating bacterial infections. Ampicillin, on the other hand, is also an antibiotic and is like a generic name for drugs like Polycillin, Principen, and Omnipen.
Amoxicillin works by penetrating into the cell wall through the linear peptidoglycan polymer chain of Gram-negative and positive bacteria. Ampicillin, on the other hand, works by destroying transpeptidase. This substance is needed by the bacteria to build up the membrane that surrounds them. However, when both are used together, they work by preventing the formation of cell walls that act as a protection to the bacteria
Water solutions of a plethora of substances, quickly pass through plant or animal semipermeable barriers, while others such as gelatin do not pass through them. The first elements are called crystalloids, and the second is called colloids. Colloidal particles are larger and heavier than the ions and most of the molecules, so their diffusion and osmotic pressure are low.
The suspension is a heterogeneous liquid, encompassing insoluble solid particles which are large enough to settle but for some time are present throughout the volume of the liquid matrix. The particles in the colloid cannot be seen with a naked eye. Colloids do not undergo sedimentation, and suspensions are heterogeneous. Colloid particles can pass through filter paper, and suspension particles cannot.
