Answer:
i think interstellar dust......
Answer:
True
Explanation:
Resonance is a concept in chemistry that describes bonding in polyatomic molecules or ions whose structure cannot be efficiently described by a single Lewis structure. Individual resonance structures do not actually exist, that is, they are not real. None of the contributing resonance structures can be said to adequately represent the molecule or ion. However, the hybrid of all the possible resonance structures of the molecule or ion gives a holistic representation of the exact structure of the molecule or ion.
Answer:
6.0 L
Explanation:
For this question, we can use
P1×V1= P2 × V2
where
P1 (initial pressure)= 0.2 kPa
V1 (initial volume)= 15L
P2 (final pressure)= 0.5 kPa
V2(final volume)= ?
Since we are trying to find final volume, we can rearrange the equation to make V2 the subject.
V2= (P1 × V1)/ P2
V2= (0.2 ×15)/0.5
V2 =6 L
Answer:
16 g
Explanation:
Step 1: Write the balanced equation
2 Na + Cl₂ ⇒ 2 NaCl
Step 2: Identify the limiting reactant
The theoretical mass ratio (TMR) of Na to Cl₂ is 46:71 = 0.65:1.
The experimental mass ratio (EMR) of Na to Cl₂ is 10:10 = 1:1.
Since EMR > TMR, Cl₂ is the limiting reactant
Step 3: Calculate the mass of NaCl produced
The theoretical mass ratio of Cl₂ to NaCl is 71:117.
10 g Cl₂ × 117 g NaCl/71 g Cl₂ = 16 g NaCl
