Answer:

The bromine molecule, represented as Br2, is expected to interact with Sr in a manner akin to the chlorine molecule, Cl2.

Explanation:

Chlorine is found in group 7 of the periodic table, known as the halogens, where its molecular formula is Cl2. Bromine follows chlorine in the same group, yielding the molecular formula Br2. Due to their analogous characteristics, bromine is likely to react with Strontium similarly to chlorine.

Elements within the same group share comparable chemical traits because they possess an identical number of valence electrons. Both chlorine and bromine are in group 7 and each has seven valence electrons. Though chlorine is more reactive and thus has a more vigorous reaction with metals, both elements ultimately react to form salts, developing negatively-charged ions with a -1 charge.

Reactions of Strontium with halogens include:

With chlorine: Sr + Cl2 ---> SrCl2

With bromine: Sr + Br2 ---> SrBr2

These resulting salts are crystalline in nature, exhibiting high melting and boiling points.

What mass of carbon dioxide (co2) can be produced from 86.17 grams of c6h14 and excess oxygen?
lorasvet [2795]
2C6H14 + 13O2 ---> 6CO2 +14H2O

Calculating the molar mass of C6H14: M(C6H14)=12.011*6 +1.008*14 ≈ 86.17 g/mol

Thus, 86.17 g of C6H14 corresponds to 1 mole.

                                  2C6H14 + 13O2 ---> 6CO2 +14H2O
based on the equation        2 mol                            6 mol
according to the question    1 mol                            3 mol

To determine M(CO2): M(CO2)= 12.011 + 2*15.999= 44.009 g/mol
Therefore, 3 mol CO2*44.009 g/1 mol CO2 ≈ 132.0 g CO2
Final answer: 132.0 g CO2

If two solutions with concentrations of 0.4 M sugar and 0.7 M sugar respectively are separated by a semipermeable membrane, duri
lions [2927]

Response: Water molecules migrate from the dilute to the concentrated solution

Clarification:

During osmosis, when a solution is separated by a semipermeable membrane, the solvent (commonly water) moves from the less concentrated solution, regarding solute content, through the semipermeable membrane towards the solution with a higher concentration to balance the concentration levels between the two solutions.

Thus, in this scenario, water molecules flow from the 0.4M sugar solution to the 0.7M sugar solution through the semipermeable membrane.

A student reported to her instructor that her unknown contained salt, salicylic acid, and sand. In reality the unknown contained
lorasvet [2795]
From the provided data, the unknown mixture was composed of salt, salicylic acid, and sand. It is understandable that the student suspected the presence of sand, yet scientific experimentation must verify such assumptions. The test involving salt and salicylic acid reveals that salt dissolves in water, while salicylic acid is only slightly soluble, and sand does not dissolve at all. By introducing the unknown into water, the salt would dissolve first, followed by the partial dissolution of salicylic acid. Heating the mixture could allow for the evaporation of salicylic acid, resulting in the remaining salt. If traces of sand were observed in the dissolved sample, it could suggest contamination.
