Place the characteristics for each phase of matter into the table where it belongs
Answers
Answer:
Solid- Definite shape
Solid and Liquid- Definite volume, Not easy to compress, if at all
Gas- No Definite Volume
Liquid and Gas- No Definite shape
The characteristics for each phase of matter in the table where it belongs are as follows:
Solids: Definite shape, very little particle motion. Liquids: Fluid motion. Gases: No Definite Volume, easily compressed. Solids and liquids: Definite volume, Not easy to compress, if at all. Liquids and Gases: No Definite shape, constant, fast particle motion. What are the different States of matter?The states of matter may be defined as the three distinct physical forms which matter can take in most environments. They are as follows:
Solid.Liquid.Gas.Each of the states of matter significantly possesses specific chemical and physical properties. For example, solids generally have a definite volume, are relatively rigid, and atoms or molecules are attached to each other very compactly.
Liquids possess a definite volume and have the ability to alter their shape through flowing. The atoms are loosely bonded to one another.
Gas has no definite volume or shape. This state of matter is easily compressed as well.
Therefore, the characteristics for each phase of matter in the table where it belongs are well described.

The difference between sunspots solar flares and prominence
Answers
Answer:
Sunspots are cooler and darker than the rest of the Sun's surface. They are marked by intense magnetic activity. Solar prominences are the plasma loops that connect two sunspots. Solar flares and coronal mass ejections are eruptions of highly energetic particles from the Sun's surface.
Explanation:
Answer:
Sunspots are dark areas on the surface of the Sun that are cooler than surrounding areas. They appear in groups, vary in size, and cycle in number over an 11-year period. Solar flares are sudden eruptions of energy from a small area of the Sun's surface. They are extremely hot (10 to 20 million degrees Celsius) and extend into the corona. Solar flares occur near sunspots and can disturb radio communications on Earth.

The Fischer projection of L-ketononose is:
H

CH₂OH-C=O-H

C

CH₂OH
Fischer projection is a two-dimensional representation of a three-dimensional molecule. In Fischer projection, the carbon atoms are drawn as vertical lines, and the hydrogen atoms and hydroxyl groups are drawn on the right-hand side or left-hand side of the carbon atoms. The carbonyl group is always drawn at the top of the Fischer projection.
The L-configuration is a type of configuration that is assigned to organic molecules based on the orientation of the hydroxyl group on the penultimate carbon atom. If the hydroxyl group is on the left-hand side of the Fischer projection, the molecule is assigned the L-configuration. If the hydroxyl group is on the right-hand side of the Fischer projection, the molecule is assigned the D-configuration.
In the Fischer projection of L-ketononose, the hydroxyl group on the penultimate carbon atom is on the left-hand side, so the molecule is assigned the L-configuration.

Calculate the number of moles in 8200 grams of iron
Can someone help me with this?
Answers
Answer:
150 moles (2 sig. figs.)
Explanation:
to convert from ...
grams to moles => divide by formula weight
moles to grams => multiply by formula weight
this problem:
Given mass of Iron (Fe) = 8200g
formula wt of Fe = 56g/mole
moles = mass/formula wt = 8200g / 56g/mol = 146.42857 moles (calculator) = 150 moles (2 sig. figs.)
The number of moles in 8200 grams of iron is 57.69 moles of Fe.
What is Mole concept ?Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g.
The number of particles present in one mole of any substance is Avogadro Number and is equals to 6.023 x 10²³ particles.
Given ;
Weight : 8200 grams of ironTo find ;
Mole (n) : ?Formula used :
Mole (n) = given weight / atomic weight= 8200 / 56 (atomic weight of Fe = 56 gm)
= 157.69 moles of Fe.

1. A 1500kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is
a pipe with radius 24cm.
a) If there is no net force on the car, calculate the pressure in the pipe.
Answers
Answer:
the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
Explanation:
a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below
As we know that
Pressure = F ÷ area
Also
F = mg
Now
= (1500 × 9.8) ÷π (0.24)^2
= 81,726 N/m^2
Hence, the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
S8 + 12 O2 —> 8 SO3 what volume of oxygen would be required to completely react with 45.7g of S8
Answers
Answer:
47.9L of oxygen would be required
Explanation:
Assuming oxygen gas is at STP
Based on the reaction:
S₈ + 12 O₂ → 8SO₃
1 mole of S₈ (Molar mass: 256.52g/mol) reacts with 12 moles of oxygen.
To solve this question we must find the moles of S₈ added. With the reaction we can find the moles of O₂ and using PV = nRT we can find the volume of oxygen required:
Moles S₈:
45.7g * (1mol / 256.52g) = 0.178 moles S₈
Moles O₂:
0.178 moles S₈ * (12 moles O₂ / 1mol S₈) = 2.138 moles O₂
Volume O₂:
PV = nRT
V = nRT / P
Where V is volume
n are moles = 2.138 moles
R is gas constant 0.082atmL/molK
T is absolute temperature = 273.15K at sTP
P is pressure = 1 atm at STP
V = 2.138mol*0.082atmL/molK*273.15K / 1atm
V = 47.9L of oxygen would be required

Answer:
a. 3; b. 5; c. 10; d. 12
Explanation:
pH is defined as the negative log of the hydronium concentration:
pH = -log[H₃O⁺] (hydronium concentration)
For problems a. and b., HCl and HNO₃ are strong acids. This means that all of the HCl and HNO₃ would ionize, producing hydronium (H₃O⁺) and the conjugate bases Cl⁻ and NO₃⁻ respectively. Further, since all of the strong acid ionizes, 1 x 10⁻³ M H₃O⁺ would be produced for a., and 1.0 x 10⁻⁵ M H₃O⁺ for b. Plugging in your calculator -log[1 x 10⁻³] and -log[1.0 x 10⁻⁵] would equal 3 and 5, respectively.
For problems c. and d. we are given a strong base rather than acid. In this case, we can calculate the pOH:
pOH = -log[OH⁻] (hydroxide concentration)
Strong bases similarly ionize to completion, producing [OH⁻] in the process; 1 x 10⁻⁴ M OH⁻ will be produced for c., and 1.0 x 10⁻² M OH⁻ produced for d. Taking the negative log of the hydroxide concentrations would yield a pOH of 4 for c. and a pOH of 2 for d.
Finally, to find the pH of c. and d., we can take the pOH and subtract it from 14, giving us 10 for c. and 12 for d.
(Subtracting from 14 is assuming we are at 25°C; 14, the sum of pH and pOH, changes at different temperatures.)
