Answer:
Yes
Explanation:
It is possible that a non polar molecule contain polar bonds.
Consider the example of CO₂:
In carbon dioxide the atoms are arranged in angle of 180 degree and molecule is linear. So in this way the net dipole movement becomes zero and molecule is non polar.
But when we see the electronegativity of both bonded atoms the oxygen is more electronegative than carbon. The oxygen atom have partial negative charge and carbon have partial positive charge because shared pair of electron is more attracted towards the oxygen. Thus bond become polar because one end is partial positive and other is partial negative. Thus a non polar carbon dioxide molecule have polar bond.
Rutherford's gold foil experiment proved that there was a small, dense, positively charged nucleus at the center, which contained most of the mass of the atom. Which contained electrons orbiting the nucleus.
Answer:
Explanation:
1: the sciencetific name of a giant squid is called Architeuthis
2: i dont know I think it says diet but: Giant squid mostly eat deep water fishes and other squids.
3: the range of a Giant squid can be found in oceans around the world at depths of at least 2,950 feet, but their exact range is unknown.
4, characteristics,
1: it has two large fins attached to its mantle.
2: the giant squid have many unique features, such as their ability to produce 'ink' to distract and deter predators.
3:
facts,
1: Their eyes are the largest eyes in the animal kingdom and are about 10 inches
2: Their big eyes help them to spy objects in dark depths where most other animals would see nothing
3: Until 2005, nobody had ever seen a giant squid that was alive.
4: According to the stories, an huge squid would wrap its arms around a whale, causing a terrible fight to start.
5: Giant squid have small fins at the rear of their mantles used for locomotion.
Human IMPACT
Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving.
Answer:
Explanation:
Example #1: How many moles of oxygen will occupy a volume of 2.50 L at STP? Standard ... What is the volume of gas at 2.00 atm and 200.0 K if its original volume was ... P2 = 2.00 atm 2.000tm) 273k. T=273k. 200.0k. Tz= 200.0k. V, = 200.0L ... A gas has a pressure of 0.370 atm at 50.0°C. What is the pressure at standard.
<h2>Entropy of the system decreases when methane gas and oxygen gas combust to form carbon dioxide and water.</h2>
Explanation:
- Salt crystals when dissolved in water the bond between the molecules of crystals are broken down increasing the movement between the atoms hence entropy is increased.
- When air escapes from a hole in the balloon,the entropy increases as the air present inside the balloon occupies small volume as compared to outside.
- Ice when melts at room temperature its entropy increases because the molecule in the ice are closely packed hence less movement between the molecules.
- When water boils the kinetic energy increases or themovement between the atoms increases which increases the entropy.
Hence, the option (a), (b), (c), and (d) are not suitable to the statement that "the entropy of the system decreases".
- During combustion of methane gas there is release of carbon dioxide gas and water .Here, entropy decreases due to the formation of water which is due to overall decrease in the kinetic energy of the system.
