Answer:

Cl2 + 2NaBr --> 2NaCl + Br2

Explanation:

This is a single displacement reaction where one side of the ionic compound switches with the other.

So, Cl2 + NaBr ---> NaCl + Br2

This isolates the Bromine and puts the Chlorine in it's place.

Then, balance out the equation like so and you should get

Cl2 + 2NaBr --> 2NaCl + Br2

Remember the acronym "Oil Rig". Oxidation is loss, Reduction is gain of electrons. Calcium is losing electrons so it's an oxidation reaction.

STatiana [176]

Answer:

Looking at the inside of the bowl

Explanation:

The curvature of the bowl would likely focus the light to a single point or area above it. This higher intensity area would be more dangerous to look at.

How are properties useful in classifying materials
lukranit [14]
S. Properties can be anything from composition to color to ductility. Without knowing an object's properties, it is impossible to characterize it. For example, looking at some common properties of metals helps to differentiate them from non-metals or metalloids.

For the reaction represented by the equation 2KClO3 → 2KCl + 3O2, how many grams of potassium chlorate are required to produce 1
Vikentia [17]

 The grams  of potassium chlorate  that are required  to produce 160 g of oxygen  is   408.29  grams

 

<u><em>calculation</em></u>

 2 KClO₃→  2 KCl  + 3O₂

Step 1:  find the  moles of  O₂

moles  =  mass÷  molar mass

from periodic table  the  molar mass of O₂  = 16 x2 = 32 g/mol

moles  = 160 g÷ 32  g/mol =  5 moles

Step2 : use the  mole   ratio to determine the  moles of KClO₃

from equation given KClO₃ : O₂  is 2:3

therefore the v moles of KClO₃  =  5 moles x 2/3 = 3.333  moles


Step 3:  find the mass  of KClO₃

mass= moles x molar mass

from periodic table  the molar mass of KClO₃

= 39 + 35.5 + (16 x3) =122.5 g/mol


mass  = 3.333 moles x 122.5 g/mol =408.29 grams
