Answer:

gallium and germanium

Explanation:

hope it will help you

The element that would form +4 ions is Germanium. The correct option is b Germanium

From the question,

We are to determine which of the given elements will form +4 ions.

Gallium belongs to group 13 and will form +3 ions because the its oxidation state is +3.

Germanium belongs to group 14 and it forms stable oxidation state of +2 and +4. Therefore, Germanium will form +4 ions.

Calcium belongs to group 2 on the periodic table. Its oxidation state is +2 and it forms +2 ions.

Magnesium also belongs to group 2 on the periodic table. Its oxidation state is +2 and it forms +2 ions.

Hence, the element that would form +4 ions is Germanium. The correct option is b Germanium

In chemistry, the inductive effect is an effect regarding the transmission of unequal sharing of the bonding electron through a chain of atoms in a molecule, leading to a permanent dipole in a bond.

Answer:

A endocytosis

Explanation:

The process by which a cell takes in a large particle is called endocytosis. Therefore, the correct option is option A.

Endocytosis is the procedure by which molecules are actively transported into the cell by being engulfed by its membrane. All cells use endocytosis and exocytosis to transport substances that cannot passively cross the membrane. Exocytosis serves the opposite purpose by ejecting molecules from the cell.

The requirement for homeostasis ensures an equal flow all molecules into and out of a cell, like all of the body's systems. This indicates that the number of molecules exocytosis and endocytosis both equal the number of molecules into the cell. The two systems work together to maintain a balance between nutrients and waste that is necessary for normal cell growth and function. The process by which a cell takes in a large particle is called endocytosis.

Therefore, the correct option is option A.

Answer:

paired electrons is magnetic configuration

Answer:

C

Explanation:

The molecules are farther apart in steam than in water.

Answer:

D. They form chemical bonds through electron sharing.

Explanation:

The correct characteristic of all ions is that they have a charge. Therefore option B is correct.

An ion is an atom or a molecule that has gained or lost electrons, resulting in an unequal number of protons and electrons. This imbalance of positive and negative charges gives the ion a net electrical charge.

Ions can have a positive charge (called cations) if they have lost electrons, or a negative charge (called anions) if they have gained electrons.

The charge of an ion is essential in determining its behavior and interactions with other ions and molecules. It influences the way ions form chemical bonds and participates in chemical reactions.

The charge of an ion is indicated by a superscript after the chemical symbol, such as Na+ for a sodium cation or Cl- for a chloride anion.

Option C: Combustion and synthesis only

Explanation:

This reaction is referred to as combustion reaction because carbon is burnt in oxygen to produce carbon (IV) oxide.

Also, it's a synthesis reaction because the two different atoms which are Carbon and oxygen interact to form a different compound which is CO2.

Thus, the correct answer is Option C: combustion and synthesis only

Answer:

Explanation:

The given chemical formula is;

             4H₂O                 H₈O₄

H₂O signifies 2 atoms of hydrogen bonding with 1 atom of oxygen

H₈O₄ signifies 8 atoms of hydrogen bonding with 4 atoms of oxygen

  The 4 coefficient before H₂O signifies the number of moles.

It appears H₂O is 4 moles of water

                  H₈O₄  is 1 mole of the compound

The number of moles of each of the compound differs.

The difference between the two chemical formulas has been on the basis of the number of the molecules present. There have been 4 molecules of [tex]\rm H_2O[/tex], while only 1 molecule of [tex]\rm H_8O_4[/tex].

The chemical formula has been used for the determination of the number of atoms of each element present in the compound.

The chemical formula 4 [tex]\rm H_2O[/tex] gives the idea that there have been 4 molecules of water, with each molecule has consisted of 2 hydrogens and 1 oxygen atom. The total number of atoms has been 8 hydrogen atoms and 4 oxygen atoms.

The chemical formula [tex]\rm H_8O_4[/tex] gives insight into the presence of 1 molecule having 8 atoms of hydrogen and 4 atoms of oxygen.

The similarity in the chemical formula has been the presence of the same number of atoms. The difference between the two chemical formulas has been on the basis of the number of the molecules present. There have been 4 molecules of [tex]\rm H_2O[/tex], while only 1 molecule of [tex]\rm H_8O_4[/tex].

Answer:

Answer:

Molarity = 0.002 M

Explanation:

Given data:

Mass of calcium chloride = 0.321 g

Volume of water = 1.45 L

Molarity of solution = ?

Solution:

Molarity = number of moles / volume in litter.

We will calculate the number of moles of calcium chloride first.

Number of moles = mass/molar mass

Number of moles = 0.321 g/ 110.98 g/mol

Number of moles = 0.003 mol

Molarity:

Molarity = 0.003 mol / 1.45 L

Molarity = 0.002 M

The volume of unreacted Oxygen = 1.25 L = 1.25 dm³ = 1250 cm³

Given

Combustion of propane

3.6 L CO2

7.25 L O2

Required

The volume of unreacted oxygen

Solution

Reaction

C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O

Avogadro's :  

In the same T,P and V, the gas contains the same number of molecules  

So the ratio of gas volume will be equal to the ratio of gas moles  

Vol O₂ = 5/3 x vol CO2 = 5/3 x 3.6 = 6 L

The unreacted : 7.25 - 6 = 1.25 L

Answer:

V₂ = 1.17 L

Explanation:

Given data:

Initial volume of balloon = 1.25 L

Initial temperature = 35°C

Final temperature = 15°C

Final volume = ?

Solution:

Initial temperature = 35°C (35+273.15K = 308.15 K)

Final temperature = 15°C (15+273.15 K = 288.15 K)

The given problem will be solve through the Charles Law.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.25 L × 288.15 K / 308.15 k

V₂ = 360.2  L.K / 308.15 k

V₂ = 1.17 L
