We know that the oxygen (O2) causes a glowing splint to reignite, however, let us check what is missing on the products side of the chemical equation: <span>
KBrO3 → KBr + ? 
As we see, oxygen (O2) is the element missing from the other side. Therefore the balanced chemical equation for this decomposition is as follows: </span>
<span>2KBrO3 → 2KBr + 3O2 </span>

The iron with which they make the houses or bridges is the same as our blood?
Leviafan [203]

Explanation:

yes, they are the same.

"Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles."

Fun fact:

At 4 grams per person, you'd need at least 2,352 completely drained donors to make a iron longsword out of blood.

If a chemist has 17.8 moles of N2H4O3, what is the mass of the sample?<br><br> show work plz
harkovskaia [24]

(\frac{17.8mole}{1} )( \frac{66grams}{1mole} ) \:  \:  \:  \:  17.8 \times 66 = 1.17 \times  {10}^{3} grams
the way that you get 66 is by adding he atomic mass unit of each atom in the formula. so N2 is 14 + 14 H4 is 1 * 4 and 03 is 16 * 3

How do CFC’s illustrate that technical advances can be a “double-edged” sword?
hram777 [196]

Answer:

CFC’s illustrate that technical advances can be a “double-edged” sword as CFC's were made for the advantages but soon or later it came as a disadvantage for environment.

CFC's was discovered with many advantages such as they are stable, non-corrosive, and replacement of harmful ammonia used in refrigerators  and air conditioning systems. But soon it is also discovered that CFC's are destroying  the upper atmosphere layer called ozone, which is a very big disadvantage for us. CFCs are major contributor  to global warming after carbon dioxide.

Hence, it proves that CFC’s shows how technological advancement can be “double-edged” sword.
