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.
Answers
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

Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.

Based on the data, should the scientist accept or reject his hypothesis?
Answers
Answer:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Answers
Answer:
Explanation:
franchement moi je te dis tu peut le faire tout seul aller bon travaille
The mass of water is equal to 2.48 × 10⁷ g, needs the energy of 7.14 ×10¹⁰ J to heat and boil.
What is the specific heat capacity?The specific heat capacity can be demonstrated as the quantity of energy needed to increase the temperature by one-degree Celcius in one unit of substance.
The temperature will be changed whenever there is a loss or absorption of energy by any substance.
Q = mCΔT
Therefore, there is a direct relationship between the mass of water and the amount of energy.
m ∝ q
[tex]{\displaystyle {\frac{m_1}{m_2} =\frac{q_1}{q_2}[/tex]
[tex]{\displaystyle {m_2} =\frac{q_2}{q_1} \times m_1[/tex]
Given, the energy required to heat mass(m₂) of water, q₂ = 7.14 ×10¹⁰ J
The energy to heat 1 gram of water, q₁ = 2870 J
[tex]{\displaystyle {m_2} =\frac{7.14\times 10^{14}}{2870} \times 1[/tex]
m₂ = 2.48 × 10⁷ g
Therefore, the mass of water is equal to 2.48 × 10⁷ g.

What is the percentage yield when 60 kg of ammonia is produced from 60 kg of hydrogen?
A
5.9%
B
17.6%
с
35.3%
D
50.0%
Answers
Answer:
B
17.6%
Explanation:
1. Percentage yield = (Actual yield/theoretical yield) x 100
2. You know actual yield of ammonia (60kg) so you need to work out theoretical yield.
3. mols of hydrogen = m/mr = 60,000/2 = 30,000 mols.
4. 3:2 ratio so (30,000/3) x 2 = 20,000 mols of Ammonia.
5. Therefore mass of ammonia = mr x mols = 20,000 x 17 = 340,000 grams
6. So percentage yield is (60,000/340,000) x 100 = 17.6

whereas sodium chloride has a giant ionic lattice

Suppose you have samples of three unknown solids. Explain how you could use their properties to determine whether or not they are ionic solids.
Answers
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.

The paths that planets follow around the sun are called ____ , and they are shaped like an ellipse.
Answers
The paths that planets follow around the sun are called as orbit, and they are shaped like an ellipse.
What is orbit ?The orbits of the planets around the sun are elliptical. Kepler, an astronomer, provided a clear definition of these orbits. The three rules he created are referred to as Kepler's laws of planetary motion. It says that every planet does an orbit around the sun.
The plane of Earth's orbit around the sun serves as the definition of the ecliptic. The primary planets of our solar system, their moons, some asteroids, and their orbits all roughly follow this plane.
An orbit is a curved path taken by an object, such as a planet's path around a star, a natural satellite's path around a planet, or a man-made satellite's path around a planet, moon, or asteroid.
Thus, the paths that planets follow around the sun are called as orbit.
