Write skeleton equations for the following reaction. Write the correct formula in each blank. You do not need to make the subscripts small. For example for carbon dioxide, write CO2 barium chloride + potassium sulfate → barium sulfate + potassium chloride sodium+iron(III) chloride→iron+sodium chloride

Please help me!!

1. BaCl2+K2SO4⇒BaSO4+KCl

2. Na+FeCl3⇒Fe+NaCl

Given

Word equation

Required

Skeleton equation

Solution

A chemical reaction can be expressed in terms of:  

The skeleton equation is still in unbalanced form  

So only chemical formulas of reactants and products and the relative amounts of the reactants and products are not included

For example :

•word equation

Ethane + Oxygen ⇒ Carbon dioxide + Water

•skeleton equation

C₂H₆ + O₂ ⇒ CO₂ + H₂O

•balanced equation

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

1.

word equation

barium chloride + potassium sulfate → barium sulfate + potassium chloride

skeleton equation

BaCl2+K2SO4⇒BaSO4+KCl

2.

word equation

sodium+iron(III) chloride→iron+sodium chloride

skeleton equation

Na+FeCl3⇒Fe+NaCl

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
