Answer:

The answer to your question is:

1.- CO

2.- 0.414 moles of CO2

Explanation:

Data

                               2CO   + O2      ⇒    2CO2

CO = 0.414 moles

O2 = 0.418

 

Process

theoretical ratio   CO/O2 = 2/1 = 1

experimental ratio  CO/O2 = 0.414/0.418 = 0.99

Then the limiting reactant is CO

2.-

                    2 moles of CO ---------------  2 moles of CO2

                    0.414 moles of CO ---------  x

                   x = (0.414 x 2) / 2

                   x = 0.414 moles of CO2

The diameter of a carbon atom is 1.54 å. (a) express this diameter in picometers. (b) how many carbon atoms could be aligned sid
makkiz [27]

Answer: -

(a) 1.54 x 10² pm

(b) 1.3 x 10⁶ is the number of carbon atoms could be aligned side by side in a straight line across the width of 0.2 mm.

Explanation: -

1 å = 10² pm

Diameter of a carbon atom = 1.54 å = 1.54 x 10² pm

1 mm = 10⁹ pm

Total distance = 0.2 mm = 0.2 x 10⁹ pm

Number of carbon atoms could be aligned side by side in a straight line across the width = Total distance / Diameter of a carbon atom

= \frac{0.2 x 109 pm}{1.54 x 102 pm}

= 1.3 x 10⁶

What is formed when the number of electrons is changed?
aleksley [76]

Answer:

Explanation:

Whether the electrons are added or given away makes no difference to the name given to parent atom -- It is called an ion which means that it has a charge. The word atom is reserved for something on the periodic table that has no charge.

select the equations that are correctly balanced. h2o 2o2? h2o2 fe2o3 3h2? 2fe 3h2o al 3br2? albr3 caco3? cao co2 can you clarif
natta225 [31]
<span>The choices are as follows:
h2o + 2o2 = h2o2
 fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = </span><span>cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

</span> fe2o3 + 3h2 = 2fe + 3h2o 
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.
