what mass of hi should be present in 0.300 l of solution to obtain a solution with each ph value?

Answers

Answer 1

0.054 gm of of HI should be present in 0.300 l of solution to obtain a solution with each pH value.

A solution's pH is a measure of its hydrogen ion concentration, which is a measure of its acidity. Pure water dissociates slightly into hydrogen and hydroxyl (OH) ions in equal proportions.

In chemistry, pH is a scale used to quantify the acidity or basicity of an aqueous solution. It was traditionally denoted as "potential of hydrogen". The pH of acidic solutions is lower than that of basic or alkaline solutions.

Indicators may be used to monitor pH since their colour varies as the pH changes. A visual comparison of the colour of a test solution with a standard colour chart allows for precise pH measurement to the closest whole integer. Color may be quantified more precisely if it is measured spectrophotometrically with a colorimeter or spectrophotometer.

as temperature increases, what happens to the viscosity of water? explain why this occurs, in terms of molecular interactions and the effect of changing temperature

Answers

The molecules move more quickly as the temperature rises, and their kinetic energies are better equipped to overcome the forces holding them together. As a result, the viscosity of the liquid reduces.

Why and what will happen to the viscosity when the temperature rises?

Because particles interact more quickly and for shorter periods of time as temperature rises, viscosity will also decrease because internal friction or stress will be reduced.

How does a fluid's viscosity change as its temperature changes?

The molecules become more mobile when the temperature rises due to an increase in kinetic or thermal energy. Reduced viscosity results from a decrease in the attractive binding energy.

what is the difference between the electron domain geometry of a molecule and its molecular geometry?

Answers

The fundamental distinction between electron domain geometry and molecular geometry is that electron geometry is found by taking both lone electron coordinates and bonds in the atom while molecular geometry is found utilizing just the bonds present in the atom.

Electron domain geometry is the state of a particle anticipated by considering both bond electron matches and solitary electron matches. The VSEPR hypothesis expresses that electron matches situated around a specific molecule repulse one another. These electron matches can be either holding electrons or non-holding electrons.

Molecular geometry is the state of a molecule anticipated by considering just bond electron matches. For this situation, lone electron matches are not considered. Also, two fold bonds and triple bonds are considered as single bonds.

How many moles of K₂CO3 are in a 150.0 g sample

Answers

Answer:

1.08 mol

Explanation:

To find the number of moles of potassium carbonate (K2CO3) in a 150.0 g sample, you need to know the molar mass of K2CO3. The molar mass is the mass of one mole of a substance, and it is expressed in grams per mole (g/mol).

The molar mass of K2CO3 is 138.20 g/mol. To find the number of moles in a 150.0 g sample, you can divide the mass of the sample by the molar mass:

Number of moles = mass / molar mass

= 150.0 g / 138.20 g/mol

= 1.08 mol

Therefore, there are 1.08 moles of K2CO3 in a 150.0 g sample.

Answer:

1.09 mol

Explanation:

The mass of K₂CO3 is 138

How

by calculating the individual molecular mass

K₂ + C + O3

= 2(39) + 12 + 3(16)

= 78 + 12 + 48

= 138g

formula for finding mole is

[tex]mole = \frac{given \: mass}{molar \: mass} [/tex]

Which elements form ionic bonds?

Answers

The elements which tends to form ionic bonds are metals and non-metals. Hence, the compounds that are formed from metals and nonmetals have ionic bonds between them.

Ionic bond, also known as electrovalent bond is a type of linkage that is formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Ionic bonds are formed when the valence (outermost) electrons of one atom are transferred permanently to another atom.

Ionic compounds are generally formed between elements that are metals and elements that are nonmetals. For example, let's consider the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl₂).

Lock and Key Model: In this model, the enzyme has a specific active site that fits the shape of the substrate like a lock fits a key. The substrate fits into the active site, and the enzyme catalyzes the reaction.

Induced Fit Model: In this model, the enzyme's active site is flexible and changes shape slightly to fit the substrate. The substrate and enzyme still fit together specifically, but the active site changes shape slightly to better accommodate the substrate.

Multi-Substrate Model: In this model, the enzyme has multiple active sites and can bind to and catalyze the reaction of multiple substrates simultaneously.

Freezing point is an important concept in the study of thermodynamics, as it is the point at which the energy of a system changes form and the phase of the substance changes.

ΔTf is the difference between the freezing point of the pure solvent and the freezing point of the solution. Kf is the change in freezing point per mole of solute. m is the number of moles of solute per kilogram of solvent.

His group's cube was made of.

Answers

Matt's cube, after 5 trials, had an average density of 7.40 g/cm3. From this data, Matt's group was able to determine that the cube was made of zinc.

Zinc is a silver-white metal that is commonly used for galvanizing, die-casting, and other industrial uses. It has a relatively low melting point compared to other metals, and its density is 7.14 g/cm3, making it a relatively dense metal. The average density of 7.40 g/cm3, as measured by Matt's group, is also slightly higher than the expected value of 7.14 g/cm3, possibly due to the presence of impurities in the alloy.

In order to identify the metal cube, Matt's group relied on the physical properties of the metal to make their determination. They measured the density of the cube and compared it to the expected values for various metals. By doing this, they were able to narrow down the possible metals to zinc, and their final determination was that the cube was made of zinc.

Dissolving is a physical process where a solid material is broken down into smaller particles and distributed within a liquid. This process can be achieved through several methods, such as applying heat, pressure, chemical reactions, or mechanical agitation. In a physical sense, dissolving is a process of taking a solid or liquid and forming a solution, which is a mixture of two or more substances. Dissolving is an important process in many industries, such as food production, pharmaceuticals, and chemical engineering. Dissolving is also used in everyday life, such as when adding sugar to tea or coffee.

This is due to the fact that sodium nitrate has a solubility of 37.2g/100g of water at 20°C. Solubility is the maximum amount of a substance that can be dissolved in a given amount of solvent (in this case, water). As the temperature increases, the solubility of sodium nitrate also increases.

Valence electrons are electrons that located in the outermost electron shell of an atom. These electrons, being the furthest from the nucleus and thus the least tightly held by the atom, are the electrons that participate in bonds.

Lewis structure - A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule.

Lewis structure of XeO4 is made up of one xenon and four oxygen atom, the xenon is in a central position, and all oxygen is at the surrounding position. There are four double bonds(Xe=O) present in the XeO4 lewis structure. The lewis structure of XeO4 contains 8 pairs of nonbonding electrons and 8 pairs of bonding electrons.
