In this case-
Therefore, we multiply by 2 on the reactant side and by 2 and 3 on the product side of the equation to make it equal. Equal numbers and types of each atom are present on both sides of balanced chemical equations. A balanced equation must have coefficients that are the easiest whole number ratio. Chemical reactions always preserve mass.

Is ICl4? polar or nonpolar?
Since chlorine is more electronegative than iodine, each I-Cl bond is polar. Due to the square planar geometry, the compound anion itself is not polar.
What ICl4 called?The ICl4- Lewis Structure (Tetrachloroiodide Ion), Since chlorine has a higher electronegative valence than iodine, each I-Cl bond is polar. The square planar shape, however, prevents this compound anion from being polar.
The ICl4 ion, with five nuclei, forms an octahedron with two missing opposite vertices that is square planar in shape.
A central atom is surrounded by constituent atoms, which on the same plane serve as the square's corners, in square planar molecular geometry. Transition metal complexes with the d8 configuration are common examples of the geometry. A few examples of this are Rh(I), Ir(I), Pd(II), Pt(II), and Au (III).

how many hydroxide ions are present in 509 grams of copper ii hydroxide ?
The number of hydroxide ions, OH⁻ present in 509 grams of copper (ii) hydroxide, Cu(OH)₂ is 6.28×10²⁴ ions
How do I determine the number of ions?We'll begin by obtaining the mole of copper (ii) hydroxide, Cu(OH)₂. Details below:
Mass of Cu(OH)₂ = 509 gramsMolar mass of Cu(OH)₂ = 97.56 g/molMole of Cu(OH)₂ = ?Mole = mass / molar mass
Mole of Cu(OH)₂ = 509 / 97.56
Mole of Cu(OH)₂ = 5.22 moles
Next, we shall determine the mole of OH⁻ in 5.22 mole of Cu(OH)₂. This is shown below:
Cu(OH)₂(aq) <=> Cu²⁺(aq) + 2OH⁻(aq)
From the above equation,
1 mole of Cu(OH)₂ contains 2 moles of OH⁻
Therefore,
5.22 moles of Cu(OH)₂ will contain = 5.22 × 2 = 10.44 moles of OH⁻
Finally, we shall determine the number of ions of OH⁻. Details below:
From Avogadro's hypothesis,
1 mole of OH⁻ = 6.02×10²³ ions
Therefore,
10.44 moles of OH⁻ = 10.44 × 6.02×10²³

Water waves in a lake travel 4.4 meter in 1.8 s. The period of oscillation is 1.2 s. What is their wavelength?
Answer:
3.6 meters
Explanation:
The wavelength of a water wave is the distance between two successive peaks or troughs of the wave.
To find the wavelength of the water waves in the lake, we can use the formula:
wavelength = speed / frequency
where speed is the speed of the wave and frequency is the number of cycles (peaks or troughs) that pass a fixed point in a given time period. The frequency of a wave is related to its period, which is the time it takes for one complete cycle (peak or trough) to pass a fixed point. The frequency of a wave is the reciprocal of its period, so we can rewrite the formula as:
wavelength = speed / (1 / period)
Plugging in the values from the problem, we get:
wavelength = 4.4 meters / (1 / 1.2 seconds)
wavelength = 4.4 meters / (1.2 seconds)
wavelength = 3.6 meters
So the wavelength of the water waves in the lake is 3.6 meters.
Water waves in a lake travel 4.4 meters in 1.8 s. The period of oscillation is 1.2 s. 3.6 meters is their wavelength.
What is wavelength?The wavelength of a water wave is the spatial arrangement between two successive peaks or troughs of the wave.

The frequency of a wave is related to its period, which is the time it takes for one complete cycle to pass a fixed point. The frequency of a wave is the reciprocal of its period, the formula is given as:
wavelength = speed / (1 / period)
Substitute the values from the given information, we get:
wavelength = 4.4 meters / (1 / 1.2 seconds)
wavelength = 4.4 meters / (1.2 seconds)

The coordination number of a metal ion in a complex ion refers to the number of ligands (molecules or ions that bind to the metal ion) that are coordinated or bound to the metal ion. In the complex ion [Co(en)Cl4]^-, the metal ion is cobalt (Co) and the ligands are the ethylenediamine (en) and chloride (Cl) ions.
The complex ion [Co(en)Cl4]^- has six ligands coordinated to the Co ion: four chloride ions and two ethylenediamine molecules. This means the coordination number of cobalt in this complex ion is 6.
