What is Si2Br?
You have described a fictitious chemical. When silicon combines with bromine it forms SiBr4 which is silicon tetrabromide. It does not combine in the ratio that your formula gives (which could be called disilicon bromide).
Who first recognized that the ratio of the number of atoms is the same as the ratio of the masses that combine?
The first person to recognize the total ratio of the number atoms is the same as the total ratio of the ratio of the mass is JOHN DALTON.This is also called the "Law of Multiple Proportion"
What mass of sodium chloride is produced if 92.0 g of sodium reacts with excess chlorine?
Sodium has an atomic weight of 22.99 g/mol. Chlorine has an atomic weight of 35.45 g/mol. NaCl has an atomic weight of 58.44 g/mol. Therefore 92g of sodium would yield 233.86g of sodium chloride (NaCl).
What are formula units?
A formula unit in chemistry is the empirical formulaof any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest whole number ratio of ions represented in an ionic compound.
What is the simplest part of a compound?
The simplest form for a compound, called the empirical formula, gives the simplest whole-number ratio of the elements in the compound, and may differ from the actual molecular formula. For example, the molecular formula for glucose is C6H12O6. The empirical formula would be CH2O, which can be found by dividing the molecular subscripts by 6.
What is the formula for compound rubidium and chlorine?
The compound formed between rubidium and chlorine has the formula RbCl.
What is the formula for silver plus 1 and chlorine?
The formula for silver plus one ion and chlorine is AgCl. Silver has a +1 charge (Ag+) and chlorine has a -1 charge (Cl-), so they combine in a 1:1 ratio to form the compound silver chloride.
What are the combining ratios of elements in group II with elements in Group VII of the periodic table?
The combining ratio for Group II elements with Group VII elements is 1:2. For example, calcium (Group II) will combine with chlorine (Group VII) to form calcium chloride with a ratio of 1 calcium atom to 2 chlorine atoms.
What is NaCI made of?
NaCl, or table salt, is made of two elements: sodium (Na) and chlorine (Cl). These elements combine in a 1:1 ratio to form the compound sodium chloride.
What elements make up Na Cl?
Sodium (Na) and Chlorine (Cl) are the elements that make up NaCl, which is commonly known as table salt. Sodium has a positive charge, while chlorine has a negative charge, and they combine in a 1:1 ratio to form a stable compound.
How are sodium and chlorine alike to table salt?
Table salt is composed of sodium and chlorine ions held together by an ionic bond. Sodium and chlorine are both elements that combine in a 1:1 ratio to form sodium chloride, which is the chemical name for table salt.
What is the ionic formula for Rubidium and chlorine?
Rubidium is a group 1 metal with just one valence electron. It therefore forms the ion Rb+ as it loses the electron. The ionic formula is Rb+ Cl-
A notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
Represents a compound -how are the elements in the compound and the ratio of atoms?
A compound consists of two or more elements chemically combined in a fixed ratio. The ratio of atoms in a compound is determined by the chemical formula, which shows the types of elements present and their respective proportions. The elements in a compound are bonded together through chemical interactions to form a stable structure.
Elements combine in a specific proportion?
Chemical elements combine in specific ratios to form compounds. This is governed by the principles of stoichiometry and reflects the fixed ratio of atoms in a compound's chemical formula. The specific proportion of elements in a compound determines its properties and behavior.
What two elements produce the compound sodium chloride?
Sodium chloride is produced from the elements sodium and chlorine. Sodium is a highly reactive metal, while chlorine is a non-metal gas. When they combine, they form an ionic compound known as sodium chloride (NaCl).
What is the ratio of aluminium chloride?
The chemical formula of aluminium chloride is AlCl3; the ratio Al/Cl is 1/3.
