Answer: Metalloids
Explanation:
The dark “stair step” line on the right side of the periodic table is where the metalloids are. Metalloids “touch” the SSL. (Stair step line)
The metals are to the left of the SSL and the non metals are to the right of the SSL.
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.
90.0 g of vanadium (V) oxygen sample has 1.50 x 10 24 oxygen atoms.
To determine the number of oxygen atoms in a vanadium oxide sample, the following steps must be made.
Step 1: Convert the mass of vanadium(V) oxide to mol of vanadium(V) oxide
mol vanadium(V) oxide = mass / molar mass
mol vanadium (V) oxide = 90.0 g / 181.88 g/mol
mol vanadium (V) oxide = 0.49483 mol
Step 2: Convert mol of vanadium (V) oxide to moles of oxygen using mole ratio
mol oxygen = mol vanadium (V) oxide * mole ratio O / mol V2O5
mol oxygen = 0.49483 mol * 5 mol O / mol V2O5
mol oxygen = 2.47416 mol O
Step 3: Convert to oxygen atoms using Avogadro's number
atoms oxygen = mol oxygen * 6.02214 x 10 23 atoms O /mol O
atoms oxygen = 2.47416 mol O * 6.02214 x 10 23 atoms O/mol O
atoms oxygen = 1.48997 x 10 24 atoms or 1.50 x 10 24 atoms O

Hey there!:
1 mole of FeSO4 = 151.8 g/mol
25.0 g change to mole = 25.0 / 151.8
moles of FeSO4 = 0.165 moles
One mole of any substance has 6.02*10²³ units
0.165 moles to get the number of Fe ( II ) ions :
number of Fe(II) ion = 0.165 * ( 6.02*10²³ )
number of Fe ( II ) ion = 9.93*10²² units
Answer:
Electrostatic Van de Waals forces act between molecules to form weak bonds. The types of Van der Waals forces, strongest to weakest, are dipole-dipole forces, dipole-induced dipole forces and the London dispersion forces. The hydrogen bond is based on a type of dipole-dipole force that is especially powerful. These forces help determine the physical characteristics of materials.
