Copper(II) Phosphite is the IUPAC name of the given compound. Ionic compounds don't get prefixes like di-, tri- etc.
International Union of Applied and Pure Chemistry is referred to as IUPAC. The IUPAC establishes the standards for the atomic weights that are shown on the periodic table and is the acknowledged authority for chemical nomenclature, measurements, including atomic mass values. Although IUPAC produces publications in many scientific domains, including physics, biology, and chemistry, it is most recognised for its work standardising nomenclature in the chemical sector. Standardising code names for nucleotide base sequences is one of the significant things the IUPAC has achieved in these areas. Copper(II) Phosphite is the IUPAC name of the given compound.

Science wasn’t a subject so I chose chemistry but this is for my science class
Answer:
I say the 1st one I'm so terrible sorry if I'm wrong
Explanation:
Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).
The state the water is in depends upon the temperature. Each state (solid, liquid, and gas) has its own unique set of physical properties.

Two 15.Kg objects are placed at four different distances from each other. At which distance would the two objects have the strongest gravitational attraction to each other?
Answer:
The strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
Explanation:
According to Newton's law of universal gravitation, the force of attraction between two objects is proportional to the products of their masses and inversely proportional to the square of the distance of separation between the two objects. This attraction between objects is known as gravity and it applies to all objects in the universe.
From the law of universal gravitation, since their is an inverse square relationship between gravitational force and the distance of separation between two interacting objects, an increase in the distance of separation will result in weaker gravitational forces. For example, if the distance of separation between two objects is increased by a factor of 2, then the force of gravitational attraction is decreased by a factor of 4 (since 2² = 4). However, if the distance of separation between the two objects is decreased by a factor of two, i.e. is halved, then the force of gravitational attraction is increased by a factor of 4.
Thus, the strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
The strongest gravitational attraction happens when the distance between the objects is smaller.
At which distance should we place the objects?We know that the gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
This means that, because the mass of the objects does not change, the only thing that we can change to change the strength of the force is the distance between the objects, and because as we increase the distance the force decreases, we should select the smallest distance between the two objects.
Concluding, the strongest gravitational attraction happens when the distance between the objects is smaller.

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.

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?

Inner shell electrons are not shared between atoms when they form
chemical bonds.
1.TRUE
2.FALSE
Yes, the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.
Why inner shells are not shared?Inner shell electrons are not shared between atoms when they form chemical bonds but the outermost electrons can form bonds with the atoms because they are easy to lose and share.
So we can conclude that the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.

How can a chemical reaction be sped up? Select from the drop-down menu to correctly complete the statement. Expose more of the reactant by increasing the A. Cataclyst B consentration c. Concentration d. Surface erea
Answer: A. Catalyst
Explanation:
An catalyst is used to speed up the rate of the reaction. In a biochemical reaction an enzyme is the only catalyst which is exposed to the reactant forming the enzyme substrate or reactant complex thus forming the product. The catalyst increases the product formation from the reactant by increasing the pace of the reaction. Catalyst does not get consumed in the reaction. It can be used repeatedly for multiple reactions.

Calculate the number of atoms in 0.0340 g Zn.
Answer:
moles Hg = 25.8 / 200.59 = 0.129
atoms = 0.129 x 6.02 x 10^23 =7.74 x 10^22
Moles Zn = 0.0340 / 65.39 =0.000520
atoms = 3.13 x 10^20
work in the same way : divide the mass by the molar mass and multiply by 6.02 x 10^23
Explanation:
The number of atoms in 0.0340g of Zinc (Zn) is 3.148 × 10²⁰ atoms.
HOW TO CALCULATE NUMBER OF ATOMS:
The number of atoms contained in a substance can be calculated by multiplying the number of moles of that substance by Avogadro's number (6.02 × 10²³). That is;no. of atoms = no. of moles × 6.02 × 10²³
In this question, we must first convert 0.0340g of Zinc to moles by using the following formula:no. of moles = mass ÷ molar mass
no of moles = 0.0340g ÷ 65g/mol
no of moles = 5.23 × 10-⁴mol
Hence, the number of atoms in Zinc is as follows:no of atoms = 5.23 × 10-⁴ × 6.02 × 10²³
no. of atoms = 5.23 × 6.02 × 10²³-⁴
no of atoms = 31.48 × 10¹⁹
no of atoms = 3.148 × 10²⁰ atoms.
Therefore, the number of atoms in 0.0340g of Zinc (Zn) is 3.148 × 10²⁰ atoms.Learn more: https://brainly.com/question/22552359?referrer=searchResults

For an electron with angular (azimuthal) quantum number ℓ = 2, the magnetic quantum number m can have
Answer:
-2, -1, 0, +1, +2
Explanation:
The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (m): if ℓ is equal to a number a, thus m can be any integer number between - a and +a.
According to this rule:
If ℓ = 2, thus m can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2
