3. When the water level is higher outside the flask than inside, is the gas pressure inside the flask higher, lower or the same as atmospheric pressure? (Take your time to think about this. Perhaps think of what it feels like to be 10 feet under water.)
Answer:
The gas pressure inside the flask is higher than outside the flask ornthe atmospheric pressure.
Explanation:
Given a U-tube manometer with water in between each arm of U-tube. One end is open to the atmosphere while one end is sealed to a flask filled with a gas. The water in the open end of the tube is experiencing a pressure equal to the atmospheric pressure whereas the water at the end sealed of to the flask is experiencing pressure due to the gas in the flask.
If the water level in both arms of the tube are equal, then the pressure due to the gas is equal to atmospheric pressure.
If the water level in the arm sealed to the gas is higher than that of the open end, The gas pressure is less than the atmospheric pressure.
If the water level in the arm sealed to the flask is lower than the open end, the pressure due to the gas is higher than atmospheric pressure.
From the question, when the water level is higher outside the flask than inside, then the gas pressure inside the flask is higher than the atmospheric pressure.

How many grams of Oz would be needed to produce 1.875 moles of aluminum?
4 AI + 3 O2 -> 2Al2O3
Answer:
1.4063 moles of oxygen are required
Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
4 moles of aluminium react with 3 moles of oxygen.
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =
1.4063 moles of oxygen are requiredwhich type of window is double glazed window
Answer:
Hope this helps and have a good day!
Explanation:
Double glazed is a fancy term for a window that has two panes of glass. There are also triple glazed windows (three panes). The multiple panes of glass in a single window frame helps with insulation.
Black hair (B) is dominant to brown hair (b). Cross a black rabbit and a brown hair. The black rabbit had a brown haired mother.
What is the punnet square for this and the genotype and phenotype for this.
Answer:
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
Explanation:
This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).
According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Bb, Bb, bb and bb
This means that the;
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
How much pressure does an elephant with a mass of 2200 Kg and a total footprint area of 4500 cm2 exert on the ground?
Answer:
47911.1 pa
Explanation:
The SI base unit of pressure is pascal, which is N/m^2.
2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.
So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.

What is the temperature range for our planet? Why is this important?
Answer:
are temperature range for are planet is -129 ⁰F (-18⁰C) that's the minimum.
+136⁰F (+58⁰C) this is the maximum surface temperature
Explanation:
"the planet is not too close or too far away from the sun, earth's atmosphere also plays a vital role is regulating the temperature by providing a blanket of gases that not only protects us from excessive heating and harmful radiation from the sun, but also traps heat rising from earth's interior core, keeping us warm"- Space.com

List 4 interesting facts about the element Cobalt
Answer:
Cobalt was the first metal to be discovered since prehistoric times and the first metal with a recorded discoverer.
Cobalt-60 is used to create gamma rays which are used to treat cancer and to sterilize medical supplies.
Cobalt is one of only three naturally occurring magnetic metals, making it very useful for the uniquely calibrated magnets found in generators and hard drives. ...
Cobalt has been utilized by man for at least the last 2,600 years, providing blue pigments for glassware and ceramics.

Hund’s rule
Pauli exclusion principle
Answer:
Hunds Rule
Explanation:
The principle states that electrons in the same sublevel (p, d, or f) are placed in individual orbitals, before they are paired up, to increase atomic stability is Aufbau principle, therefore option (a) is correct.
What is Aufbau principle ?
Aufbau principle states that electrons are filled into atomic orbitals in the increasing order of orbital energy level.
According to the Aufbau principle, the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels.

Which element is more reactive? *
Cs
Rb
Answer:
Rubidium is a typical but very reactive member of the series of alkali metals. It is appreciably more reactive than potassium, but less so than caesium, and so would be expected to react more violently with those materials that are hazardous with potassium or sodium.
Answer:
Rb is more reactive .
Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.

How many moles of H2O form when 4.5 moles O2 reacts?
Explanation:
Start with a balanced equation.
2H2 + O2 → 2H2O
Assuming that H2 is in excess, multiply the given moles H2O by the mole ratio between O2 and H2O in the balanced equation so that moles H2O cancel.
5 mol H2O × (1 mol O2/2 mol H2O) = 2.5 mol O2
Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.

What is one disadvantage of using nuclear fission to produce electricity?
Answer:
D
Explanation:
Answer is the last one.......
Nuclear reaction of which nuclear fission is a type has a disadvantage that it is difficult to store and dispose of radioactive wastes.
What are nuclear reactions?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock.
Answer:
The rock changes into a Metamorphic rock
Explanation:
Usually, metamorphic rocks start out as some other type of rock, either igneous, sedimentary or even a metamorphic rock. The process of transformation is known as Metamorphism.
When a rock sitting on the surface of the earth is pushed down deep into the earth over time and is exposed to tremendous heat and pressure over time and does not melt, it changes into a metamorphic rock.
A metamorphic rock is formed from a combination of factors such as tremendous heat, high pressure, hot fluids rich in minerals which are all found deep down in the earth.
