Answer:
Cobaltous Nitride,I think so anyway.......
The formula name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride.
In the compound [tex]Co_{3}N_{2}[/tex], the Co represents the chemical symbol for cobalt, and the N represents the chemical symbol for nitrogen. The subscript numbers indicate the ratio of atoms present in the compound.
To name the compound, we determine the charge of the cobalt ion based on the ratio of cobalt and nitrogen atoms. In this case, since there are three cobalt atoms and two nitrogen atoms, each cobalt atom has a 2+ charge.
Therefore, the correct name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride. The Roman numeral II is used to indicate the cobalt ion's charge.

A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.
Which organism in the food chain is
responsible for transforming radiant
energy into chemical energy?
Grass->Prairie Dog -> Coyote -> Soil Bacteria
Answer:
The organism in the food chain responsible for transforming radiant energy into chemical energy is;
Grass
Explanation:
Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;
6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂
Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples
Answer:
See explanation
Explanation:
While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.
Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.
Let us look at three examples;
The carbohydrate in food is composed of carbon, hydrogen and oxygen
The stainless steel materials we use are composed of iron, carbon and other trace elements
Glass is made up of silicon, oxygen and other elements
Only 90 naturally occurring elements capable of combining with each other to form millions of substances.
Compounds:
When two or more elements combine in a certain ratio to form a molecule.
For example-
Water is made up of two hydrogen and one Oxygen ration is 2:1.
If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.
Water gives life and Hydrogen peroxide can kill a person.
Other examples are,
The carbohydrate in food is composed of carbon, hydrogen and oxygen. The stainless steel is made up of iron, carbon and other trace elements. Glass is composed of silicon, oxygen and other elements.Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?
Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :
[tex]P_1V_1=P_2V_2[/tex]
We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]
So, the new volume of the gas is 236.84 mL.
What is the molecular formula for C5H7 if its molar mass is 536 g/mol?
Answer:
(C5H7)8
Explanation:
It's empirical formula is given as; C5H7
Molar mass of carbon(C) = 12 g/mol
Molar mass of hydrogen(H) = 1 g/mol
We are told that it's molar mass is 536 g/mol.
To find the molecular formula;
Molecular formula = n × empirical formula
Thus;
n = 536/((12 × 5) + (1 × 7))
n = 8
Thus;
Molecular formula = (C5H7)8

A tank for storing liquid as a base of area 1.5 meters square. What is the pressure on the base of the tank when it contains water weighting 4500n
Answer:
3000 Nm^2
Explanation:
We must remember that pressure is defined as force per unit area.
We have been given the following information in the question;
Area of the tank= 1.5 m^2
Weight of water in the tank = 4500N
And;
P = F/A
F= force
A = area
P = 4500 N/1.5m^2
P= 3000 Nm^2

When kci dissolved in ethanol what is the intermolecular attraction between k+ ions and ethanol molecules
Answer:
ion-dipole interaction
Explanation:
Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.
The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.
When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433
Answer:
0.0493 moles de Titanio
Explanation:
Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:
Volumen de la esfera:
Volumen esfera = 4/3π * Radio³
Volumen = 0.5236cm³
En m³ (1m³ = 1x10⁶cm³):
0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³
Masa en gramos:
5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio
Moles -Masa molar Ti: 47.867g/mol-:
2.36g de Titanio * (1mol / 47.867g) =
