Answer: Solubility.
Explanation:
Solubility is defined as the maximum amount of solute dissolved per 100 g of the solvent at a certain fixed temperature to form a saturated solution.
STP condition is Standard Temperature and Pressure condition which is temperature of 273 K and pressure of 1 atm.
Thus the scientific term for "the number of grams of solute dissolved in 100 g of the solvent to form a saturated solution at STP" is called as Solubility.

What is wrong with writing the electron configuration of a ground state atom as 1s2 2s2 2p6 3s2 3p6 4s2 4d1?
Answer:
4d - orbital makes the given electronic configuration wrong.
Explanation:
The order of electronic configuration is written as;
1s²
2s² 2p⁶
3s² 3p⁶ 3d¹⁰
4s² 4p⁶ 4d¹⁰ 4f¹⁴
5s² 5p⁶ 5d¹⁰ 5f¹⁴
6s² 6p⁶ 6d¹⁰ 6f¹⁴
7s² 7p⁶ 7d¹⁰ 7f¹⁴
In order of energy level from the lowest to the highest, the configuration of the given atom in ground state can be written as;
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹, when compared to the given configuration, 4d orbital makes the given configuration wrong, because the next orbital after 4s is 3d.

identify the oxidizing agent and the reducing agent for Ca(s)+Fe2+(aq)→Ca2+(aq)+Fe(s)
Answer:
Ca reducing agent
Fe2+ Oxidizing agent
Explanation:
Ca ------> Ca2+ +2electrons.
Calcium loses two electrons and oxidises itself and reduces others so Ca is a reducing agent.
Fe2+ +2electrons ------> Fe
Fe 2+ reduces itself by gaining electron and oxidizes other so Fe2+ is Oxidizing agent.

1. What kind of reaction is the one above? *
O A. Single replacement
O B. Double replacement
O C. Composition aka synthesis
O D. Decomposition
O E. Organic combustion
Answer:
D (Decomposition)
Explanation:
This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.
2. How do we find the number of neutrons in an atom?
(10 Points)
a. Add the protons and electrons
b. Subtract the protons from the electrons
c. Subtract the atomic number from the atomic mass
d. Subtract the atomic mass for the atomic number
Answer:
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number.
Explanation:
Answer:
Letter C. Subtract the atomic number from the atomic mass

The acceleration of an object is equal to the net force exerted on the object (blank) the object's (blank).
Answer:
Divide; mass.
Explanation:
The acceleration of an object is equal to the net force exerted on the object divided the object's mass. This theory is known as Newton's second law of motion.
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making acceleration (a) the subject, we have;
[tex]Acceleration (a) = \frac{F}{m}[/tex]
Therefore, the acceleration of an object is equal to the net force exerted on the object divided the object's mass.
The acceleration of an object is equal to the net force exerted on the object divided by the object's mass.
The net force applied to an item divided by its mass gives the object's acceleration.
To put it another way, the equation that connects mass (m), net force ([tex]F_{net[/tex]), and acceleration (a) is:
a = [tex]F_{net[/tex] / m
This equation is derived from Newton's second rule of motion, which states that an object's acceleration is inversely proportional to its mass and directly proportional to the net force acting on it.
Thus, it shows that an item accelerates more quickly the more net force that is applied to it, and that an object accelerates more quickly the more mass that is added to it.

Classify the following compound as an alkane, alkene, or alkyne.
Answer:
I think it's alkyne!
Please give brainliest!
The compounds containing triple bonds between carbon atoms are called alkynes. The given compounds contains one triple bond between two carbons atoms hence, it is an alkyne.
What are alkynes ?Hydrocarbons are organic compounds containing carbon- hydrogen bonds. There are three types of hydrocarbons namely alkanes, alkene and alkynes.
Alkanes are compounds containing only single bonds between all carbon atoms in the chain. Alkanes are called saturated hydrocarbons. Alkenes are unsaturated because they contains one or more double bonds between carbon atoms.
Alkynes are compounds with one or more triple bonds between carbon atoms in the chain. Alkynes are also unsaturated. The given compound contains one triple bond between a pair of carbon atoms. Thus, it is an alkyne.

Given 7.3 moles of Ethane Gas (C2H6) and Excess Oxygen, how many moles of CO2 would be produced in the following combustion reaction? Round to 1 decimal place. Assume 1 Mole Ethane = 30.07 g of Ethane
2C2H6 + 7O2 --> 4CO2 + 6H2O
Answer:
Explanation: Find moles of product formed when C2H6 is burned in excess oxygen? Mass percent of ethane in a mixture before it goes through combustion with propane. Combust to create water and co2. Using gas stoichiometry find the volume of sulfur burned in excess of oxygen: Gas pressure inside a vessel: 1.60 grams of methane (CH4) is combusted.
Use the bond dissociation energies of H2 (435 kJ/mol) and of a typical carbon–carbon bond (347 kJ/mol) to decide which bond is stronger. Explain your reasoning.
Answer:
H2 bond is stronger
Explanation:
In this question, we are trying to make a connection between bond dissociation energy and the strength of a bond.
First of all, we must know that any bond that is quite stable must have a large bond dissociation energy. This means that more energy is supplied in order to cleave the bond.
A high bond dissociation energy actually implies that a bond is of low energy and consequently stable.

CH4 + 202 → CO2 + 2H2O
How many grams of O2 needed to produce 36 grams of H2O?
Answer:
Mass = 64 g
Explanation:
Given data:
Mass of water produced = 36 g
Mass of oxygen needed = ?
Solution:
Chemical equation:
CH₄ + 2O₂ CO₂ + 2H₂O
Number of moles of water produced:
Number of moles = mass/molar mass
Number of moles = 36 g/ 18 g/mol
Number of moles = 2 mol
Now we will compare the moles of water and oxygen.
H₂O : O₂
2 : 2
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 2 mol × 32 g/mol
Mass = 64 g
