What is the state change of a gas to a liquid is called?
Answers
Answer:The process in which a gas changes to a liquid is called condensation. Other examples of condensation are shown in Figure below. A gas condenses when it is cooled below its boiling point.
Explanation:
There are 4 phases for h20 solid liquid vapour and gas.
In the vacuum of space there are only 2 phases solid and gaseous, both liquid and vapour cannot exist in the absolute freezing temperature of the vacuum of space and crystalise instantly.
Watch a space shuttle dump water in space and it instantly freezes, and when in direct sunlight instantly turn to its gaseous phase and becomes invisible to the naked eye by the process of sublimation.
When h20 freezes in the shadow of the shuttle to ice crystals they instantly sublimate to the a gaseous state when they come into contact with direct sunlight.
You can see all 4 phases if you place ice cubes [ solid phase ] in a pan on a stove, the Solid beComes liquid [ liquid phase ]and the liquid becomes a gas in the bottom of the pan when the water boils, [ gaseous phase ] the bubbles coming up from the bottom are the instant phase change from liquid to gas, when the gas bubbles break the surface of the water and the gas comes into contact with the cooler air the gas instantly starts to condense to water droplets i.e. the vapour phase
You can see through the bubbles because h20 in its gaseous phase is invisible to the naked eye.
Gaseous h20 is hot dry and invisible
Vaporous h20 is warm wet and visible
Gaseous h20 is known as a condensing gas in physics because it condenses obviously, condensing gases are also known as optically active gases or radiatively active gases.
Hope this helps all the 3 phase numpties who think vapour i.e. water droplets is actually gas, it isnt or it wouldn’t be called vapour it would be called gas.
Liquid water has to reach its boiling point before it will phase change to its gaseous phase.
Vapor has to boil before the water droplets will phase change to a gaseous state, steam is not gas it is condensing gas i.e. vapour at a lower temperature than boiling point.
hope this helps have a nice day

transmutation occurs during which type of radioactive decay
Answers
Explanation:
Transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq. v.).

The reaction rate provides information about how quickly products will be made in a chemical reaction.
The reaction rate is a measure of how fast a chemical reaction proceeds over time. It provides information about the speed at which reactants are consumed and products are formed during a reaction. The reaction rate is typically expressed as the change in concentration of a reactant or product per unit of time.
The reaction rate is influenced by various factors such as the nature of the reactants, concentration of reactants, temperature, surface area, and the presence of catalysts. By measuring the reaction rate, scientists can gain insights into the kinetics of a reaction and understand the factors that affect its speed.
The reaction rate is particularly important because it allows us to predict and control the rate at which products are formed. It is useful in various applications, including industrial processes, pharmaceutical development, and environmental studies. By manipulating the reaction conditions, such as adjusting the concentration of reactants or introducing a catalyst, we can alter the reaction rate to achieve desired outcomes.
In summary, the reaction rate provides valuable information about the speed at which products are formed in a chemical reaction, allowing us to understand and control the kinetics of the process.

True or false: The phenolphthalein indicator changes colour close to the point of neutralization which shows the end-point of the titration.
Answers
Answer:
True
Explanation:
A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.
Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.
In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.
Hence, the given statement is correct, the indicator changes its color close to the end point of titration.

Answer:
El número atómico se refiere al número de protones o electrones de un átomo.
Explicación:
El número atómico se refiere a la cantidad de protones o la cantidad de electrones que giran alrededor de las capas u órbita de un átomo, por lo que el número atómico 7 representa que el átomo tiene 7 electrones o protones mientras que, por otro lado, el número atómico 17 muestra el número de electrones o protón. Solo hay dos electrones que entran en la primera órbita y en el resto de las capas tiene espacio para 8 electrones por lo que los átomos pierden o agregan electrones en su capa más externa para obtener estabilidad.

What is the mass of an atom with 8 protons, 8 electrons, and 8 neutrons?
Answers
Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
Explanation:
The mass of the atom with 8 protons, 8 electrons, and 8 neutrons would be approximately 16 atomic mass units as the number of electrons has an almost negligible contribution to the mass of the atom.
What is atomic mass?It is the sum of the mass of all the protons as well as the neutrons that are present inside the nucleus.
Atomic mass = total number of protons present in the nucleus + total number of neutrons present in the nucleus of an atom,
As given in the problem we have to find the atomic mass of the atom with eight protons, eight electrons, and eight neutrons,
This given specified atom clearly represents the oxygen atom as it has eight electrons protons and neutrons each.
Thus, the atomic mass of the given atom would be 16.

True or false? To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from a 10.0 M stock solution, you should take 4.00 mL of the stock solution and add 20.0 mL of water.
Answers
False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.
Recall the law of diffusion that:
C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.
In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL
V1 = 2 x 20/10
= 4.0 mL
Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.
