A gas occupies a volume of 120 mL at 700 mm Hg. What will happen to the volume of the gas if the pressure is changed to 1500 mm Hg at constant temperature
Answer:
56 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
[tex]V_2 = \frac{700 \times 120}{1500} = \frac{84000}{1500} = \frac{840}{15} \\ = 56[/tex]
We have the final answer as

When light waves pass through solids, the speed of the wave ___________.
remains the same
decreases
increases
It woukd decrease.
I am sure its correct you can trust me becuase I took the test.
Answer:
The speed of the wave decreases.
Explanation:
When light waves do pass through a medium, any solid, liquid, or gas, the speed of the waves actually decreases. Solids are more dense than liquids, so they decrease the speed of light even more.

Why is partial pressure of oxygen greater at lower levels in water.
Answer:
Therefore, the partial pressure of oxygen at high altitudes is less than at sea level.
Explanation:
The deep ocean thus has higher oxygen because rates of oxygen consumption are low compared with the supply of cold, oxygen-rich deep waters from polar regions. In the surface layers, oxygen is supplied by exchange with the atmosphere.
You have 505 mL of a 0.160 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add
This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.
In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:
[tex]M_1V_1=M_2V_2[/tex]
Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:
[tex]V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL[/tex]
Hence, the following amount of water must be added:
[tex]V_w=808mL-505mL=303mL[/tex]

Which sentence from the article BEST describes HOW fireworks produce colors in the sky?
(A)
It needs an oxidizer, a fuel and a chemical mixture to produce the color.
(B)
Over the years, scientists have staged various chemical reactions to produce fireworks of different
colors.
(C)
The color of that light depends on what chemical elements are present.
(D)
When the casing explodes, pellets containing the chemical color mixtures fly out.
Fireworks need an oxidizer, fuel, and a chemical mixture to produce the colour in the sky. Therefore, option (A) is correct.
How do colours come from firecrackers?The chemicals which are used in crackers are the main reason for the colours in the sky. The colours in the fireworks come from different compounds which are the binder and the colourant. The colourant chemicals provide the colours in the firework while the binder is the agent that binds the fuel and is responsible to burn up the colourant in the firework.
The colourants in the firecrackers can be generated with the use of various metallic salts. These salts can be defined as iconic compounds which possess an anion or an acid and a cation or a base. The metal salts are responsible for generating intense colours when they are burned.
For example, if use calcium salts in the firework will produce an orange colour, and copper salts will produce a bright blue colour.

When a substance changes from a solid to a liquid, is a new substance made?
Answer:
no
Explanation:
it means melting or fusion so yhe answer is no
A substance changes from a solid to a liquid no its is not the formation of new substance. It is the change of state of the matter.
What are the states of matter?The states of matter can be defined as one of the several configurations in which matter can exist.
There are basically three states of matter.
Solid - It is defined as hard, distinct in volume and shape. Atoms and molecules are joined together to form solids.Liquid - It is defined as defined volume with the ability to flow and change shape. Atoms and molecules are only weakly bound together in liquids.Gases - It is defined as no clear shape or volume.Thus, a substance changes from a solid to a liquid no its is not the formation of new substance.

how is the miscibility of two liquids related to their polarity?
Answer:
The more polar the liquid, the more likely that it is miscible with water. The polarity of a liquid does not affect its miscibility with water. The less polar the liquid, the more likely that it is miscible with water. The more polar the liquid, the less likely that it is miscible with water.
Explanation:
hope it helps you
Miscibility of two liquids are directly related to their polarity. The likelihood that a liquid will mix with water increases with its polarity.
What is polarity?Polarity is the arrangement of electrical charge among the atoms connected by a chemical bond. Because both hydrogen atoms in H2 were electrically neutral, bonds among atoms of different elements were electrically inequivalent, as opposed to bonds among identical atoms, which are electrically uniform.
The likelihood that a liquid will mix with water increases with its polarity. Liquid miscibility with water is unaffected by the polarity of the liquid. The likelihood that a liquid will mix with water increases with decreasing polarity. The likelihood that a liquid will be miscible with water decreases with increasing polarity.
Therefore, miscibility and polarity are directly related.

lifes?
Answer: The information about sequential order of the event occurred in the past can be obtained by using only relative dating method.
Explanation:
Relative dating method doesn’t give information about when it happened. It provides sequential order of the events. It is the art of deciding the overall happening of past occasions (i.e., the age of an item in contrast with another), without fundamentally deciding their outright age (for example evaluated age).
In topography, shake or shallow stores, fossils and lithologies can be utilized to correspond one stratigraphic segment with another.
Q.2. Which of the following statements is true of second ionization energies?
a) That of Al is higher than that of Mg because Mg wants to lose the second electron, so it is easier to take the second electron away
b) That of Al is higher than that of Mg because the electrons are taken from the same energy level, but the Al atom has one more proton
c) That of Al is lower than that of Mg because Mg wants to lose the second electron, so the energy change is greater
d) That of Al is lower than that of Mg because the second electron taken from Al is in a p orbital, so it is easier to remove it.
Answer:
a) That of Al is higher than that of Mg because Mg wants to lose the second electron, so it is easier to take the second electron away
Statement which is true regarding second ionization energy is that ionization energy of of Al is higher than that of Mg because Mg wants to lose the second electron, so it is easier to take the second electron away.
What is ionization energy?Ionization energy is defined as the minimum amount of energy required to remove an electron which is loosely held in the outermost shell to form an isolated gaseous atom,ion or molecule.
It has a positive value for neutral atoms indicating that the ionization process is an endothermic process . The closer the outermost shell electrons are to the nucleus of an atom higher is it's ionization energy.It is expressed in electron volts or joules.
Ionization energy increases across period as more energy is required to remove electron from an atom as it is closely held along a period while it is decreasing down the group as on going the group the inter-nuclear distance increases and as a result less energy is required to remove an electron.
