Answer:
26.9 L SO₂
Explanation:
Step 1: Write the balanced equation
S(s) + O₂(g) = SO₂(g)
Step 2: Establish the appropriate volume ratio
For gases at the same conditions, the volume ratio is equal to the molar ratio. The volume ratio of O₂(g) to SO₂(g) is 1:1.
Step 3: Calculate the liters of SO₂ produced from 26.9 L of O₂
We will use the previously established volume ratio.
26.9 L O₂ × 1 L SO₂/1 L O₂ = 26.9 L SO₂
Let's assume ideal gas behavior for simplicity. We could use the equation below:
PV=nRT
Solve for n or the number of moles.
n = PV/RT = (3×10⁻³ atm)(1 L)/(0.0821 L·atm/mol·K)(250 K)
n = 1.462×10⁻⁴ moles ozone
For every 1 mole of any substance, Avogadro stipulated that there is an equivalent of 6.022×10²³ molecules. Thus,
# of ozone molecules = 1.462×10⁻⁴ mol * 6.022×10²³ molecules/1 mol
<em># of ozone molecules = 8.8×10¹⁹</em>
The B. atomic mass of an atom is based on the mass of an atom of carbon-12.
The <em>ionic charge</em> depends on the number of <em>electrons</em>.
The <em>atomic number</em> depends on the number of <em>protons</em>.
<em>Isotopes</em> depend on the number of <em>neutrons</em>.
I believe the answer is C. Does not touch it
Someone please correct me if I am wrong.
Answer:
<em>In the given question Brianna is trying to make a </em><em>whole figure by combining different single elements.</em>
Explanation:
Here are the different coloured that are used to join and make one piece this method that Brianna is following is called synthesis.
The combination here is of simple substances that are combined directly to make a complex compound. The compound formed is complex while the substances that combined together can be element or compound or a combination of both.
