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.

Suppose you have samples of three unknown solids. Explain how you could use their properties to determine whether or not they are ionic solids.
Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.
What are Ionic solids?An ionic solid is a solid formed by ionic bonds. They are the solid version of ionic compounds, which are held together by strong electrostatic energies. What properties do they possess?Among their many properties, ionic solids possess high melting and boiling points.These solids are also known to conduct electricity well when dissolved into water, however, this can be tested after melting them as they will not conduct electricity in a solid state.A final property that we can use to identify them is that they provide a good means of insulation.Each of these properties can be tested and will allow us to determine the ionic solids amongst the samples.Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.

how many grams are in 4.07x10^15 molecules of calcium hydroxide
There are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles in the substance by its molecular mass.
However, given that the number of molecules in calcium hydroxide is 4.07 x 10¹⁵molecules, we need to calculate the number of moles in Ca(OH)2 as follows:
no. of moles of Ca(OH)2 = 4.07 x 10¹⁵ ÷ 6.02 × 10²³
no. of moles = 0.676 × 10-⁸
no. of moles = 6.76 × 10-⁹ moles.
Molar mass of Ca(OH)2 = 74.093 g/mol
Mass of Ca(OH)2 = 74.093 × 6.76 × 10-⁹ moles
Mass = 5.01 × 10-⁷grams.
Therefore, there are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.

a terminal alkyne was treated with nanh2 followed by propyl iodide. the resulting internal alkyne was treated with ozone followed by water, giving only one type of carboxylic acid. provide a systematic, iupac name for the internal alkyne.
The systematic Iupac name for the internal alkyne is : 4-octyne
When only one type of carboxylic acid is made the internal alkyne will be symmetric and the compounds can be 3-hexane or 4-octyne but given that one of the reactants is propyl iodide. Therefore
The Internal alkyne will have an Iupac name 4-octyne
Hence we can conclude that the systematic Iupac name for the internal alkyne is 4-octyne

If I remove the table from under the book, what will happen to the book? Think about Newton’s second law of motion. Is there an acceleration? What caused the acceleration?
Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth
Newton's Second law of motion states that "the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object."
In our case the mass of the book and the force of gravity

draw the lewis structure for co with an arrow representing the dipole moment. refer to figure 10.10 to estimate the percent ionic character of the co bond.
The formation of molecule can easily be shown by drawing Lewis dot structure. Since atom's Lewis dot structure has three dots. Therefore, in below given ways, we can have Lewis dot structure of CO.
What is Lewis dot structure?Lewis dot structure is a way to represent the valence electron of an element in the form of dot. These are mainly beneficial in understanding the chemical formula of covalent compound.
Carbon contains four valence electrons, whereas oxygen has six. Carbon has five electrons but oxygen has seven electrons if just one link is established among carbon and oxygen atoms.
The solitary connection formed in between two atoms is insufficient to form an octet on every atom. A triple bond is required to finish the octet of the each atom in CO. The six electrons shared by these two atoms create a triple bond. The dipole moment arrow will point between carbon to oxygen.
Therefore, in above given ways, we can have Lewis dot structure of CO.
