(2)KClO3 = (2)KCl + (3)O2
you have 2 Potassium Chlorates for every 2 Potassium Chlorides and 3 Oxygen
Ponds are most likely to dry up
Answer:
103.6°C
Explanation:
We solve this problem, with the Ideal Gases Law. We know that moles of gas are not changed through time.
P . V = n . R . T
So n (number of moles) and R (Ideal Gases constant) are the same, they are cancelled. In the two different states, we can propose:
P₁ . V₁ / T₁ = P₂ . V₂ /T₂
We need to make some conversions:
100 mL . 1 L/ 1000mL = 0.1L
500 kpa . 1atm / 101.3 kPa = 4.93 atm
300°C + 273 = 573 K
We replace data:
4.93 atm . 10L / T₂ = 750 atm . 0.1L / 573K
4.93 atm . 10L = (750 atm . 0.1L / 573K) . T₂
(4.93 atm . 10L) / (750 atm . 0.1L / 573K) → T₂
T₂ = 376.65 K
We convert K to °C → 376.65 K - 273 = 103.6 °C
Answer: This animation explores water as a solid, liquid and gas. The water molecules stay the same, but they behave differently as they change from one form to another.
Explanation:
The correct answer is B, 'the same type of atom'. By definition, an element is a single type of atom. They are the most basic forms of matter, and so they cannot be more than one kind of atom, and they also cannot be a compound, since compounds are made up of multiple atoms.
Hope this helps!
