Answer:
Explanation:
A physical change is a change in which the physical properties of matter are altered. These are properties are the forms and state.
Most physical changes are easily reversible and are pure state changes.
They do not lead to the production of new compounds.
They involve no mass change and requires little to no energy.
Examples are melting, boiling, freezing, sublimation e.t.c
A. Acids increase the number of OH- ions in a solution. FALSE
B. Bases increase the number of OH- ions in a solution. TRUE
C. Acids increase the number of H+ ions in a solution. TRUE
D. Bases increase the number of H+ ions in a solution. FALSE
Answer:
1200 J/K
Explanation:
The formula for the entropy associated with a reversible phase change is
1. Calculate q
For a reversible phase change like melting,
2. Calculate ΔS
Answer:
A product in science is a substance that is formed when two or more chemicals react.
Explanation:
When a chemical reaction takes place, a new substance is often created from the atoms or molecules of the original substances. There are often multiple products formed in a reaction.
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.
