Answer:
Cirrus
Cirrus cloudsCirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands.
Cirrostratus
Cirrostratus cloudsCirrostratus clouds are thin, white clouds that cover the whole sky like a veil. These clouds are most commonly seen in the winter, and can cause the appearance of a halo around the sun or the moon.
Cirrocumulus
Cirrocumulus cloudsCirrocumulus clouds are thin, sometimes patchy, sheet-like clouds. They sometimes look like they’re full of ripples or are made of small grains.
Mid-level Clouds (6,500-23,000 feet)
Altocumulus
Altocumulus cloudsAltocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. They are lower than cirrus clouds, but still quite high. They are made of liquid water, but they don’t often produce rain.
Altostratus
Altostratus cloudsAltostratus clouds are gray or blue-gray mid-level clouds composed of ice crystals and water droplets. The clouds usually cover the entire sky.
Nimbostratus
Nimbostratus cloudsNimbostratus clouds are dark, gray clouds that seem to fade into falling rain or snow. They are so thick that they often blot out the sunlight.
Low Clouds (less than 6,500 feet)
Cumulus
Cumulus cloudsCumulus clouds look like fluffy, white cotton balls in the sky. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe!
Stratus
Stratus cloudsStratus cloud often look like thin, white sheets covering the whole sky. Since they are so thin, they seldom produce much rain or snow. Sometimes, in the mountains or hills, these clouds appear to be fog.
Cumulonimbus
Cumulonimbus cloudCumulonimbus clouds grow on hot days when warm, wet air rises very high into the sky. From far away, they look like huge mountains or towers.
Stratocumulus
Stratocumulus cloudStratocumulus clouds are patchy gray or white clouds that often have a dark honeycomb-like appearance.
Special Clouds
Contrails
(Photo of white streaks of contrails in the sky) Contrails are made by high-flying jet airplanes. They are still clouds, though, because they are made of water droplets condensed from the water vapor in the exhaust of the jet engines.
Weather prediction: Contrails can provide information about the layers of moisture in the sky.
Mammatus clouds
Mammatus cloudsMammatus clouds are actually altocumulus, cirrus, cumulonimbus, or other types of clouds that have these pouch-like shapes hanging out of the bottom. The pouches are created when cold air within the cloud sinks down toward the Earth.
Orographic clouds
Orographic cloudsOrographic clouds get their shape from mountains or hills that force the air to move over or around them. They can also be formed by sea breezes and often appear as lines where two air masses meet.
Lenticular clouds
Lenticular clouds are shaped like lenses or almonds or...flying saucers! They may get their shape from hilly terrain or just the way the air is rising over flat terrain.

Explanation:
Ideal gas law is valid only for ideal gas not for vanderwaal gas. The pressure will remain same as the initial pressure on decreasing volume and temperature by half.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. real gas can become ideal gas at low pressure and high temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of gas
V= volume of gas =1/2V
n =number of moles of gas
T =temperature of gas =T/2
R = Gas constant = 0.0821 L.atm/K.mol
Substituting all the given values we get
P×(V/2)=nR(T/2)
(PV)/2=(nRT)/2
PV=nRT
Therefore, the pressure will remain same as the initial pressure on decreasing volume and temperature by half.

155.0-ml of a solution of 0.75 M HNO3 is combined with 270 g of magnesium. What
volume of hydrogen gas will be produced at STP?
Answer:
The volume occupied by the gas is 1.302 × 10⁻³ m³
Explanation:
2HNO₃(aq) + Mg(s) → Mg(NO₃)₂ + H₂(g)
From the above reaction, we have that 2 moles of HNO₃ combine with 1 mole of Mg to produce 1 mole of Mg(NO₃)₂ and 1 mole of H₂
In the question, we have 155.0 mL of a solution of 0.75 M HNO₃ combining with 270 g of magnesium
Therefore, number of moles of HNO₃ = 0.75×155.0/1000 = 0.11625 moles
[tex]Number \, of \, moles \ of \ magnesium = \frac{Mass \ of \, magnesium}{Molar \, mass \ of \, magnesius} = \frac{270}{24.305} = 11.11 \ moles[/tex]
Therefore, HNO₃ is the limiting reaction, hence;
0.11625 moles of HNO₃ will react with 1/2×0.11625 moles or 0.058125 moles of Mg to produce 0.058125 moles of H₂
Hence since we now know the volume of H₂ produce, we can find the volume occupied at STP by the following universal gas equation relationship;
PV = nRT
Therefore;
[tex]V = \frac{n \times R \times T}{P}[/tex]
Where:
V = Volume of occupied by the gas = Required quantity
n = Number of moles = 0.058125 moles
R = Universal gas constant = 8.3145 J/(mol·K)
T = Temperature of the gas at STP = 273.15 K
P = Pressure of the gas at STP = 1 atm = 101325 Pa
[tex]V = \frac{0.058125 \times 8.3145 \times 273.15}{101325} = 1.302 \times 10^{-3} m^3[/tex]

This group of fungi has reproductive cells with flagella so that they can swim
Answer:
The answer would be chytrids.
Chytridiomycota (chytrids) is a group of fungi that has reproductive cells with flagella so that they can swim.
What is Chytridiomycota?The fungus known as the amphibian chytrid fungus only infects frogs. A frog uses its skin to maintain homeostasis. The chytrid fungus ruins the frog's ability to swallow, exchange ions, and function normally when it affects its skin.
The fungus targets the keratin-containing areas of a frog's skin. Frogs have trouble breathing because they use their skin for respiration.
As a class of fungi, chytrids are regarded as the most basic. They are primarily aquatic, and the only fungus cells known to contain flagella are those of the gametes. They can reproduce asexually or sexually; the latter method produces zoospores.
Therefore, a class of fungi known as chytrids possesses reproductive cells with flagella that allow them to swim.

An exothermic reaction releases 13,450J of heat. How many calories of energy are released? A) 5 56,274 calories B)1,244 caloriesC) 134,500 caloriesD) 3,215 calories
Answer:
The correct option is;
D) 3,215 calories
Explanation:
Here we are to convert the units of energy
The given units is in Joules, J, while the required units is in calories, where the calorie is defined as the amount of heat required to raise the temperature of 1 gram of water by 1°C
The conversion formula therefore is 1 calorie = 4.1868 J
Hence, 1 J = 1/4.1868 calories
13,450 J = 13,450 × 1/4.1868 calories = 13,450 /4.1868 calories = 3212.477 calories
∴ 13,450 J ≈ 3,215 calories.
The temperature of a sample of gas in a steel

A. 5.17 kPa
B. 51.7 kPa
C. 517 kPa
D. 5170 kPa
Answer:
[tex]P_2=51.7kPa[/tex]
Explanation:
Hello,
In this case, we apply the Gay-Lussac's law which allows us to understand the pressure-temperature behavior via a directly proportional relationship:
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
Thus, since we are asked to compute the final pressure we solve for it in the previous formula, considering the temperature in absolute Kelvin units:
[tex]P_2=\frac{P_1T_2}{T_1}=\frac{30.0kPa*(25.0+273)K}{(-100.0+273)K} \\\\P_2=51.7kPa[/tex]
Best regards.
Answer:
B = Pressure = 51.7kPa
Explanation:
P1 = 30kPa
T1 = -100°C = (-100 + 273.15)K = 173.15K
T2 = 25°C = (25 + 273.15)K = 298.15K
P2 = ?
This question involves the use of pressure (p) law which states that the pressure of a fixed mass of gas is directly proportional to its temperature(t) provided that the volume of the gas is kept constant.
Mathematically,
P = kT, k = P / T
P1 / T1 = P2 / T2 = P3 / T3 =.......= Pn / Tn
P1 / T1 = P2 / T2
Solve for P2,
P2 = (P1 × T2) / T1
P2 = (30 × 298.15) / 173.15
P2 = 8944.5 / 173.15
P2 = 51.66kPa
The pressure of the gas is approximately 51.7kPa
