Aluminum has metallic bonds between its atoms. Which statement BEST describes the
valence electrons in aluminum?
are exchanged with nonmetal atoms
are exchanged with other metal atoms
are localized and stay between metal atoms
are delocalized and move between metal atoms
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.
What is the molecular formula of the following compound: NH_CI, molar mass = 51.5 g/mol?
Answer:
Explanation:
Explanation:
As you know, the empirical formula tells you what the smallest whole number ratio that exists between the atoms that make up a compound is.
In your case, you know that the empirical formula is
NH Cl
2
, which means that the regardles of how many atoms of each element you get in the actual compound, the ratio that exists between them will always be
1:2:1.
What you actually need to determine is how many empirical formulas are needed to get to the molecular formula.
Notice that the problem provides you with the molar mass of the compound. This means that you can use the molar mass of the empirical formula to determine exactly how many atoms you need to form the compound's molecule.
molar mass empirical formula×n=molar mass compound
To get the molar mass of the empirical formula, use the molar masses of its constituent atoms
14.0067 g/mol+2×1.00794 g/mol+35.453 g/mol=51.48 g/mol≈
51.5 g/mol
This means that you have
51.5g/mol×n=51.5g/mol
As you can see, you have
n=1.
This means that the empirical formula and the molecular formula are equivalent,
NH Cl.
2
Answer:
NH_Cl 2 is the answer to What is the molecular formula of the following compound: NH_CI, molar mass = 51.5 g/mol?

How can you measure the volume of an irregular shaped solid?
Answer:
If the object has an irregular shape, the volume can be measured using a displacement can. The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the tap. As the irregular object is lowered into the displacement can, the water level rises.

How can scientists use stoichiometry to ensure that commercial products contain the components that manufacturers claim they do?
Answer:
I know you have been waiting awhile for this question to be answered :)
Stoichiometry is used in industry quite often to determine the amount of materials required to produce the desired amount of products in a given useful equation. Each one of these products requires stoichiometry. There would be no products from these industries without chemical stoichiometry.
Explanation:
Hopefully this helps :D
Sorry you had to wait so long :(

Aluminum fluoride is the name of the following ionic compound. The recognised authority on chemical terminology and nomenclature is IUPAC.
IUPAC is the widely acknowledged authority on chemical terminology and nomenclature, and two IUPAC organisations play key roles in this activity: The Interdivisional Commission on Terminology, Nomenclature, as well as Symbols and Division VIII - Chemical Nomenclature or Structure Representation. Unambiguous, uniform, and reliable nomenclature as well as terminology for particular scientific fields are developed by IUPAC as one of its main activities. These recommendations are typically presented as glossaries of terms for particular chemical disciplines. Aluminum fluoride is the name of the following ionic compound.

How does the temperature of the air cause a breeze to blow toward the land?
Answer:
The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, high surface pressure will form because of the colder air. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze.
