Answer:

1019.27 g.

Explanation:

For the balanced reaction:

2Na + Cl₂ → 2NaCl,

It is clear 2 moles of Na with 1 mole of Cl₂ to produce 2 moles NaCl.

Firstly, we need to calculate the no. of moles of Cl₂ is needed to react with 57.5 mol Na:

2 moles of Na need → 1 mol of Cl₂, from the stichiometry.

57.5 moles of Na need → ??? mol of Cl₂.

∴ The no. of moles of Cl₂ is needed to react with 57.5 mol Na = (1 mol)(57.5 mol)/((2 mol) = 28.75 mol.

∴ the mass of Cl₂ is needed to react with 57.5 mol Na = (no. of moles of Cl₂)(molar mass of Cl₂) = (28.75 mol)(35.453 g/mol) = 1019.27 g.

Sugar is a covalently linked compound with many atoms. Water is able to dissolve sugar. What does this suggest about the atoms o

luda_lava [24]

Answer:

When you put sugar inside of a cup with water, the sugar is still visible because it's molecules have just gotten in touch with water molecules. The sugar molecules are still attracted to each other but as you stir it, it seems to disappear but not completely. When the water is stirred sugar mix with water and water molecules place themselves between the sugar ones.

Conclusion: It suggests that the sugar molecules are more attracted to water molecules which is why they easily separate from each other.

How many of each element are present in this compound 4C4HgCL

frozen [14]

Answer:

Percent Composition of Compounds

The percent composition (by mass) of a compound can be calculated by dividing the mass of each element by the total mass of the compound.

LEARNING OBJECTIVES

Translate between a molecular formula of a compound and its percent composition by mass

The atomic composition of chemical compounds can be described in a variety of ways, including molecular formulas and percent composition.
The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound.
The percent composition of a compound can be measured experimentally, and these values can be used to determine the empirical formula of a compound.

percent by mass: The fraction, by weight, of one element of a compound.
The atomic composition of chemical compounds can be described using a variety of notations including molecular, empirical, and structural formulas. Another convenient way to describe atomic composition is to examine the percent composition of a compound by mass.

Percent Composition by Mass

Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.
