The IUPAC name for NH3 is Ammonia
The IUPAC name is also known as (International Union of Pure and Applied Chemistry) and it is a standardized system by chemical scientists for naming chemical compounds.
The IUPAC name for NH3 is Ammonia. Ammonia is a colorless gas with a stifling odor that is an exceedingly unpleasant pungent smell. It dissociates quickly in water to generate ammonium hydroxide, which can irritate and burn the skin.
It serves an agricultural purpose such as fertilizer.It is also used for the production of plastics, textiles, insecticides, etc.Learn more about the IUPAC naming system here:

An electrochemical cell operates because the electrodes in the two half-cells differ in their electrical potential. A metal electrode composed of ______ reducing agent will have a greater electrical potential to push electrons toward the electrode composed of a ______ reducing agent.
A metal electrode composed of strong reducing agent will have a greater
electrical potential to push electrons toward the electrode composed of a
weak reducing agent.
Strong reducing agents are compounds which donates or loses electrons
with a corresponding increase in the oxidation state. Weak reducing agents
can also be referred to as oxidizing agents and they accept the electrons
from the strong reducing agents which results in a reduction in the oxidation
state.
The strong reducing agent has a greater electric potential which aids the
electrons being pushed towards the electrodes with a weak reducing agent.

Answer:
Answer d
Explanation:
A compound contains 70% by mass of iron and 30% by mass of oxygen.
What is its empirical formula?
(A: 0, 16; Fe, 56]
Answer:
FeO₂
Explanation:
hAVE A nice day
Explanation:
If we assume it's FexOy
Fe : O
70 : 30. (mass ratio)
x:y = 70/56 : 30/16. (mole ratio)
1.25 : 1.875
= 1.25/1.25: 1.875/1.25
= 1 : 1.5
=2 : 3
Therefore It's Fe2O3

When a gas is collected over water, the partial pressure of water must be subtracted from the total pressure. If the total pressure was 761 mmHg and the pressure for water is 17.2 torr, what is the pressure due to the gas collected
Answer is: the partial pressure of the hydrogen 500 mmHg.
p(total) = 523.8 mmHg.
p(water) = 23.8 mmHg.
p(total) = m(water) + p(hydrogen).
p(hydrogen) = p(total) - p(water)..
p(hydrogen) = 523.8 mmHg - 23.8 mmHg.
p(hydrogen) = 500 mmHg.
mmHg or millimeter of mercury is a manometric unit of pressure.

C :
H:
N:
O:
P:
CI:
Answer:
Look at the screenshot below.
Those are your answers!
Good Luck.
Explanation:
The number of valence electrons for neutral atoms is the same as the number of the atom's main group.A periodic table element's column can be used to determine its main group number.For instance, carbon, which belongs to group 4, has four valence electrons.
Use the periodic table to identify the number of valence electrons available for bonding for each of the following elements?
This rule states that each group of elements has one valence electron, two valence electrons in group 2, three valence electrons in group 13, four valence electrons in group 14, and so on. C : Six electrons make up the atom of carbon: four valence (outermost shell) electrons in the 2s and 2p orbitals, and two inner shell (core) electrons in the 1s orbital. H : As the initial element, hydrogen has an electron configuration of 1s1.Its valence shell only contains one electron.The outermost electrons or those with the highest energy level are called valence electrons. N : The periodic table's Group 15 is headed by nitrogen, which has either 3 or 5 valence electrons. O : On the periodic table, column 6 contains oxygen (symbol O).Its valence electrons number six.To obtain an octet, two bonds must be created. Ci : If chlorine removes one of its seven valence electrons, it will have eight (an octet).When chlorine gains one electron, its electron configuration resembles that of argon.If chlorine had given up all seven of its valence electrons and sodium had taken them, the octet rule would have been met.To learn more about periodic table refer

Answer:
Potential energy is the stored energy of position possessed by an object.
Potential energy is described as stored energy. Depending on the relative positions of various system components, stored energy. When a spring is squeezed or extended, its potential energy increases.
What is potential energy ?Potential energy is the power that an item may store due to its position in relation to other things, internal tensions, electric charge, or other circumstances.
A boulder perched precariously atop a cliff. The rock will be moving if it falls, converting the potential energy to kinetic energy. a longbow's stretched-elastic string.
Potential energy is the energy that is stored in any item or system as a result of its location or component arrangement. The environment outside the object or system, such as air or height, has no impact on it. Conversely, kinetic energy is the force that propels the particles of an item or a system into motion.
Since light has no mass and is an example of electromagnetic radiation, it possesses neither kinetic nor potential energy. The remaining forms exhibit both kinetic and potential energy characteristics.

is isopropyl alcohol the same as hydrogen peroxide
Answer:
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
