A tank of gas is found to exert 8.6 atm at 38°C. What would be the required
temperature to change the pressure to standard pressure?
Answer:
36.2 K
Explanation:
Step 1: Given data
Initial pressure of the gas (P₁): 8.6 atmInitial temperature of the gas (T₁): 38°CFinal pressure of the gas (P₂): 1.0 atm (standard pressure)Final temperature of the gas (T₂): ?Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K

2. How many electrons are in Lithium's outer shell?
3. How many times can Oxygen bond?
4. What is the charge on a phosphorus ion?

Answer:
jwwnwwjkqnwjwmwnqnqwnmqaj
Answer:
1. 8
2.1
3.4 times
4.3-
5. 2+
Explanation:
1. it qualifies under the octet rule and is completely stable.
2. 1 because it fills every shell and has one left over
3. each time an element like oxygen bonds it can be surrounded by 8 electrons in order to be stable and each line that you may see counts as two electrons so it can have 1 bond line in each direction.
4.&5. It just is that way

1. Is the statement true that a gas takes on the shape of the container?
2. What happened to the water when it was poured into the glass? Into the square container?
3. Did the wood have a fixed shape?
4. Of what state of matter is water an example?
5. Of what state of matter is
ice an example?
6. Of what state of matter is steam an example?
This is for a project. Complete in complete sentences. Please. Sorry if this is confusing
Answer:
1. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed
2. However after pouring the water from one short glass into a tall glass, to be the same amount after being poured into any other container
3. Yes, wood have a fixed shape. Explaination: The reason is that it's solid and solids have a definite volume and shape. ... They have shapes that do not change and volumes that can be measured
4. Water is known to exist in three different states; as a solid, liquid or gas. Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water
5. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Other examples of solids include wood, metal, and rock at room temperature
6. For example, water commonly exists in three states of matter: solid (ice), liquid (water), and gas (steam)
Explanation:
plzzzzzzzzzzzzzz give brainly
1. It will adopt its container's shape. Within a liquid, particles can move around, yet the volume is maintained because of the liquid's dense packing. Particles in gaseous stuff are arranged so haphazardly that neither their shape nor their volume can be determined.
What is liquid ?The term liquid is defined as substance which is not solid but which flows and can be poured and take a shape of container. water is an example of liquid.
2. However, the same amount of water would be poured into any other container after being transferred from one short glass to a tall glass.
3. The shape of wood is fixed. It's solid, and solids have a distinct volume and shape, which explains why. They have measurements-able volumes and unchanging forms.
4. There are three recognized states of water: solid, liquid, and gas. Snow, rain, and clouds are all composed of water in some way. A snowflake is an accumulation of several ice crystals, a cloud is made up of microscopic water droplets and/or ice crystals, and rain is just liquid water.
5. When liquids or gases are chilled, solids can occasionally form; ice is an example of a cooled liquid that has solidified. At room temperature, solids also include wood, metal, and rock.
6. As an illustration, water typically exists in three states: solid (ice), liquid (water), and gas (steam).

1. A helium-filled balloon had a volume of 8.50 L on the ground at 20.0°C and a
pressure of 750.0 Torr. After the balloon was released, it rose to an altitude where the
temperature was 40.0°C and the pressure was .550 atm. What is the new volume of
the balloon in liters at the high altitude?
Answer:
133.74 L
Explanation:
First we convert the given pressures and temperatures into atm and K, respectively:
750.0 Torr ⇒ 750/760 = 0.9868 atm20°C ⇒ 20+273.16 = 293.16 K40°C ⇒ 40+273.16 = 313.16 KThen we use the PV=nRT formula to calculate the number of moles of helium in the balloon, using the data of when it was on the ground:
0.9868 atm * 8.50 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 293.16 Kn = 2.866 molThen, knowing the value of n, we use PV=nRT once again, this time to calculate V using the data of when the balloon was high up:
0.550 atm * V = 2.866 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 313.16 KV = 133.74 LWhich is one factor that increases the speed of a sound wave? A. higher temperature B. lower temperature C. traveling in a liquid rather than a solid D. traveling in a gas rather than a liquid

Explanation:
define saturated and unsaturated fats
Answer:
SATURATED: Saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds.
UNSATURATED: Unsaturated fats are loosely packed. They tend to be liquid at room temperature.
There are two main types of unsaturated fat:
Monounsaturated
Polyunsaturated
A sample of gas at 62.0°C occupies a volume of 4.80 L at a pressure of 2.90 atm. How many
moles of gas are contained in the sample?
Answer: 37.01 moles (mol) of gas
Explanation:Use PV=nRT
which is also equal to n=PV/RT
P=2.90
V= 4.80
R = 8.31 (R will always be the same in any equation)
T= 62.0
2.90 x 4.80= 13.92 / 8.31 x 62= 515.22
13.92/13.92=515.22/13.92
n= 37.01 mol

Answer:
A. How much decay happens in each flashlight
Explanation:
In an experiment, the DEPENDENT OR RESPONDING VARIABLE is the variable that responds to changes being made to another variable called Independent variable. It is the variable that is measured by an experimenter.
In this question, an experiment was carried out to research the effect of sunlight on plastic decay. Three plastic flashlights were used for this experiment in which one was placed in a dark closet (control), and the others were placed in light at different times or intervals. However, the variable being measured or assessed is the decay of each flashlight. This means that "HOW MUCH DECAY HAPPENS IN EACH FLASHLIGHT" is the dependent variable.
