Write the balanced molecular equation for the acid-base reaction that occurs when aqueous solutions of hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed.
Answers
Answer:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
Explanation:
Sodium hydroxide (NaOH) is a strong base and hydrochloric acid (HCl) is a strong acid. That means that they are totally dissociated into ions in aqueous solution.
When a solution of NaOH is mixed with a solution of HCl, a neutralization reaction occurs, in which a salt (NaCl) and water (H₂O) are formed.
The balanced molecular equation for this reaction is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)

Answers
A balloon contains 0.950 mol of nitrogen gas and has a volume of 25.5 L. How many grams of N2 should be released from the balloon to bring the volume to 17.3 L?
Answers
Mass released = 8.6 g
Explanation:
Given data:
Initial number of moles nitrogen= 0.950 mol
Initial volume = 25.5 L
Final mass of nitrogen released = ?
Final volume = 17.3 L
Solution:
Formula:
V₁/n₁ = V₂/n₂
25.5 L / 0.950 mol = 17.3 L/n₂
n₂ = 17.3 L× 0.950 mol/25.5 L
n₂ = 16.435 L.mol /25.5 L
n₂ = 0.644 mol
Initial mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.950 mol × 28 g/mol
Mass = 26.6 g
Final mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.644 mol × 28 g/mol
Mass = 18.0 g
Mass released = initial mass - final mass
Mass released = 26.6 g - 18.0 g
Mass released = 8.6 g

A truck traveled at a constant speed for 6 hours. Then, it
decreased its speed by 13 mph for the remaining 228 miles. If
the total distance was 876 miles, how long did it take to travel
the remaining 228 miles?
h
Answers
Answer:
2.4 hrs
Explanation:
The constant speed of the truck for 6 hrs can be calculated by: speed=distance/time. Speed =(876-228)/6=648/6=108m/s. So the decreased speed = (108-13)=95m/h. Now, speed =distance /time We get 95m/h = 228/t. t=228/95 hrs = 2.4 hrs PLEASE MARK ME THE BRAINLIEST!!

Which of the following substances are soluble in water? Select all that apply.
a. NaCl
b. AgCl
c. AgNO3
d. KNO3
Answers
A, C and D are soluble in water.
What is solubility?Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature.
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
AgCl is also not soluble in water because the forces favouring the formation of silver hydroxide (AgOH) are too weak to break the ionic bonds between silver and chlorine in AgCl. That means a bond between silver cation and the chloride ion is strong.
Silver nitrate is highly soluble in water but is poorly soluble in most organic solvents, except acetonitrile. It readily dissolves in water due to its strong ionic properties.
Potassium nitrate ([tex]KNO_3[/tex]) crystals were insoluble in water at room temperature. Heating the solution increases the solubility of the crystals in water.
Hence, A, C and D are soluble in water.

Which statements correctly describe chemical reactions? Select all that apply.
Answers
Answer:
The statements that correctly describe chemical reactions are
A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.
C. If the reactants include an aluminum atom, then the products must include an aluminum atom.
E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.
Explanation:
In a chemical reaction, reactants are the elements or compounds that react to give a particular product(s). The reactants are the substances that start the chemical reaction and they are found at the left hand side of the chemical equation. While the products are found at the right hand side of the chemical equation and they are seen at the end of the reaction.
In chemical reaction, the number of atoms that starts the reaction remains the same. That is the same number of atoms is seen in the products. This follows the law of conservation of matter - which postulates that matter cannot be created or destroyed.
But in a chemical reaction, number of molecules are not conserved.
The statements that correctly describe chemical reactions are:
A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.
C. If the reactants include an aluminum atom, then the products must include an aluminum atom.
E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.
Chemical Reaction:A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. If a physical change occurs, the physical properties of a substance will change, but its chemical identity will remain the same.
Thus, the statements that are true for a chemical reactions are A, C and E.

Answers
Answer: Beryllium is the fourth element with a total of 4 electrons. In writing the electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital. Therefore the Be electron configuration will be 1s22s2.
Explanation:
Orbital notation represents an atom of beryllium in the ground state is [tex]1s^22s^2[/tex].
Beryllium atom:Beryllium is the fourth element with a total of 4 electrons. Beryllium atoms have 4 electrons and the shell structure is 2.2. The ground state electron configuration of ground state gaseous neutral beryllium is [tex][He] 2s^2[/tex]. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized. Electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital.
Therefore, the Be electron configuration will be [tex]1s^22s^2[/tex].

What do ionic bonds form between?
Answers
Answer:
Ionic bonds form between cations and anions.

Electrovalent bonds (ionic bonds) form due to the electrostatic attraction between the two oppositely charged ions in the compound. A cation is formed when a metal ion loses a valence electron. Anions are formed the opposite way: a non-metal ion gains a valence electron.
