If pressure is kept constant and the temperature of a gas is doubled, what will happen
to the volume?
A. It will double.
B. It will remain constant
C. It will decrease to 25% of its original volume.
D. It will decrease by half.
I believe it's (A). It will double.
Explanation:
Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. (Charles's law).
The pressure, volume, and temperature are the main factors of the ideal gas. At constant pressure when the temperature is doubled, then volume also gets doubled. Thus, option A is correct.
What is an ideal gas law?The ideal gas law has been known as the law that relates the pressure, volume, moles, and temperature of the gas particles. The relationship between the volume and the temperature of the gas was given by Charle's law.
According to Charle's law, the volume and the temperature have been known to have direct relation when the factor of pressure is said to be constant. If they exhibit the direct relation then doubling the temperature will double the volume of the gas.
Therefore, option A. the doubling of temperature doubles the volume is correct.

How does the electron-cloud model describe electrons?
The exact position of an electron can be known.
An electron can be found at certain distances from the nucleus.
An electron has a high probability of being in certain regions.
Each electron follows a specific path around the nucleus.
Answer:
C. An electron has a high probability of being in certain regions.
Explanation:
In the electron cloud model, there are no electron-orbits around the nucleus but a cloud. This cloud has various densities with respect to distance from the nucleus. The most dense region of the cloud (which is the region close to the nucleus) is where electrons has the highest probability of existence.
The model explains that an electron a greater chance of being in the region closer to the nucleus. Thus, an electron has a high probability of being in certain region of the cloud about the central nucleus. And an electrostatic force exists between the nucleus and the electrons.

Why should acids be stored
only glass
in
containers
Answer:
Acids are typically stored in glass containers because some acids will destroy plastics or react with them forming inedible products as these plastics are modified petroleum products and hence, corrode the plastic vessels easily. Glass on the other hand is not corroded by these acids so they are a good option.
Explanation:
Thus, acids are carefully stored in glass containers due to their chemical inertness towards the acid because of which glass does not react chemically with most of the aqueous substances like acids. Glass containers are non-porous, which means they do not absorb or contaminate acids anyhow and keep them preserved.

When a car uses a gallon of gas, how much carbon dioxide is emitted into the environment? I give branlyest
Answer:
19.5
Please tell me if wrong.
When a car uses a gallon of gas, 22.0 miles per gallon of carbon dioxide is emitted into the environment.
What happens when carbon dioxide is emitted?After being released into the atmosphere, carbon dioxide (CO₂) is initially quickly dispersed among the atmosphere, the upper ocean, and plants.
The sources of carbon dioxide emissions include both natural and human activities. Decomposition, oceanic discharge, and respiration are examples of natural sources.
The annual carbon dioxide emissions from a typical passenger automobile are around 4.6 metric tonnes. This estimates that the typical gasoline car on the road today gets roughly 22.0 miles per gallon of fuel and travels about 11,500 miles annually.
Thus, 22.0 miles per gallon of carbon dioxide is emitted into the environment.

How does chemical weathering differ from physical weathering? A. It causes rocks to change color B. It increases the size of the rock C. It makes the rock stronger D. It makes the rock disappear
Answer:
A. It causes rocks to change color
Explanation:
Weathering can be defined as the gradual decomposition of rock. This means, rocks are broken into pieces or sediments through the process of weathering.
There are two types of weathering process:
1. Physical weathering also known as mechanical weathering. This is the breakdown of rocks into smaller pieces without changing the composition of the rock. Physical weathering is caused by the action of ice, wind, plant growth.
2. Chemical weathering: Here, the rocks changes not just in size of pieces but in its composition. This is when other minerals are applied on the rock in other to dissolve it.
How do the products of a nuclear fusion reaction differ from reactants?
Answer:The products of nuclear fusion are by far heavier than the reactants. Nuclear fusion is the combination of small atomic nuclei into larger ones.This reaction is accompanied with the release of a large amount of energy:
²₁H + ²₁H → ⁴₂He + energy
In the above reaction,
two hydrogen atoms fuse and produce a heavier helium atom which differs from the combining atoms.

Describe wildfires. How is climate change impacting wildfires ?
Answer:
Hey mate.......
Explanation:
This is ur answer......
Climate change has been a key factor in increasing the risk and extent of wildfires in the Western United States. Research shows that changes in climate create warmer, drier conditions. Increased drought, and a longer fire season are boosting these increases in wildfire risk. But global warming has changed some of the underlying variables that make wildfires more or less likely to occur every year. Warmer temperatures increase the likelihood that fires will burn more intensely. They also cause snow to melt sooner, and lead to drier soils, forests, and plants, which act as kindling.

What is corrosion and how to avoid the process of corrosion?
Answer:
Three things are necessary for corrosion to occur: an electrolyte, an exposed metal surface, and an electron acceptor. Corrosion can be prevented by removing one of these conditions. Coating a metal surface with paint or enamel provides a barrier between the metal and the moisture in the environment.

In a titration, a few drops of an indicator are added to a flask containing 35.0 milliiters of HNO3(aq) of unknown concentration. After 30.0 millliters of 0.15 M NaOH(aq) solution is slowly added o the flask, the indicator changes color, showing the acid is neutralized. Which choice is a correct numerical setup for calculating the concentration of the HNO3(aq) solution
Answer:
0.13M HNO3 is the concentration of the unknown
Explanation:
Nitric acid, HNO3, reacts with NaOH as follows:
HNO3 + NaOH → H2O + NaNO3
Where 1mol HNO3 reacts with 1mol NaOH
To find the concentration of HNO3 we must find, as first, the moles NaOH added = Moles HNO3 in the solution:
30mL * (1L / 1000mL) * (0.15mol / 1L) = 0.0045 moles HNO3
In 35.0mL = 0.035L:
0.0045 moles HNO3 / 0.035L =
0.13M HNO3 is the concentration of the unknown
