KCIO3 → KCI + O2

First you have to count all the atoms of each element in both sides of the reaction, in this case:
Left side: there is one K atom, one Cl atom and 3 O atoms
Right side: there is one K atom, one Cl atom and 2 O atoms

K and Cl are balanced but O isn't
To balance O you can add a coefficient to O2 in the right side of the equation like this:

KCIO3 → KCI +3 O2

Now you have 6 oxygen atoms in the right side but only 3 in the left side, so you can add a coefficient to KClO3:

2KCIO3 → KCI +3 O2

And finally, Balance K and Cl again by adding a 2 as a coefficient for KCl

2KCIO3 → 2KCI +3 O2

Now both sides have the same amount of atoms of each element (2 K atoms, 2 Cl atoms and 6 O atoms)

kotegsom [21]
P1V1=P2V2, so P1V1/P2=V2.
2atm x 6.0 L/1.0 atm = 12.0 L
The new volume would be 12.0 Liters

Explain the difference between a base unit and a derived unit
Scrat [10]
<span>A SI base unit is the single and direct measurement unit for a physical entity. E.g. For mass it is kg, for time it is sec, A derived unit is determined by a physical equation with the base units, like for velocity equals distance divided by time, in SI units: unit of v (velocity)= m (meter) divided by sec (seconds).

Hope this helps!</span>

9. How many grams are in 2.0 x 105 molecules of carbon monoxide?
timama [110]

Answer: 9.3 x 10^ 18 g CO

Explanation:

Start by knowing that carbon monoxide is the compound CO. To convert molecules to grams, you first need to convert molecules to moles. This can be done using the conversion factor for Avogadro's Number:

(2.0 x 10^5 molecules CO) x 1 mol CO / 6.02 x 10^23 molecules CO

This cancels molecules CO.

Then, you can convert moles to grams, which is your desired quantity. You can find the number of grams for CO by looking at the periodic table and adding together their masses. C = 12 g and O = 16 g. Total of 28 g CO:

(1 mol CO) x 28 g CO / 1 mol CO

This cancels mol CO, which leaves grams CO.

A fluorine atom has 9 positive charge,9 negative charges and a mass of 19. Describe the structure of its atom.
Tanya [424]
The atomic structure of the atom contains 9 positively charged particles (protons) and 10 neutrally charged particles (neutrons) in the center of the atom in a clump called the nucleus. Those 9 negatively charged particles (electrons) are moving around outside of the nucleus.
There are 10 neutral charges, because the mass of 19 comes from the number of neutral charges plus the number of positive charges.
To calculate the number of neutral charges, subtract the positive charges from the mass (19 - 9), and you get the number of neutral charges (10).
