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

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
