Answer is: <span> two samples have in common same amount of substance and same number of particles.
1) There are same amount of substance in both beakers:
n(Zn) = 1 mol.
n(ZnCl</span>₂) = 1 mol.
2) There are same number of particles (atoms, molecules, ions) in both beakers:
N(Zn) = n(Zn) · Na.
N(Zn) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ atoms of zinc.
N(ZnCl₂) = n(ZnCl₂) · Na.
N(ZnCl₂) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ molecules of zinc(II) chloride.
Na - Avogadro number.
Answer:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.
Answer:
Empirical formula = S₁Cl₂ = SCl₂
Explanation:
The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.
This compound contains 31.1% sulfur and 68.9% chlorine.
That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.
Convert the mass of each element to moles using the molar mass from the periodic table.
Moles of Sulfur = 
= 0.9699
Moles of Chlorine= 
= 1.9434
Divide each mole value by the smallest number of moles calculated.
Units of sulfur = 
= 1
Units of Chlorine = 
= 2
Empirical formula = S₁Cl₂ = SCl₂
Answer:
H2 & F2
Explanation:
A covalent bond is formed when an electron is shared between two atoms. The two electrons of the covalent bond are positioned between the nuclei of the both bonding atoms. The electron pair of the bond may be equidistant from the nucleus of the two atoms or nearer to the nucleus of one of the bonding atoms than the other depending on the relative electro negativities of the both bonding atoms.
For homonuclear covalent bonds, there is no electro negativity difference between the bonding atoms. A single line may be used to indicate the shared electron pair between the two atoms.
Hydrogen and fluorine form homonuclear covalent diatomic compounds in which only a single electron pair is shared between bonding atoms. A single covalent bond is found connecting the two bonding atoms, hence the answer.
