n = 5 --> n = 4
n = 4 --> n = 3
n = 3 --> n = 2
n = 2 --> n = 1
<span>So we can see that there are 4 different wavelength of
light that can be emitted</span>
8moles of SO_2 need 11mol O_2
Moles of sO_2
So
Moles of O_2
We know
- 1mol at STP=22.4L
- 1.4mol=0.14(22.4)=3.13L O_2
Answer:
116.88 g
Explanation:
Step 1: Write the balanced equation for the synthesis of NaCl
Na + 1/2 Cl₂ ⇒ NaCl
Step 2: Calculate the moles corresponding to 45.978 g of Na
The molar mass of Na is 22.990 g/mol.
45.978 g × 1 mol/22.990 g = 1.9999 mol
Step 3: Calculate the number of moles of NaCl formed from 1.9999 moles of Na
The molar ratio of Na to NaCl is 1:1. The moles of NaCl formed are 1/1 × 1.9999 mol = 1.9999 mol.
Step 4: Calculate the mass corresponding to 1.9999 moles of NaCl
The molar mass of NaCl is 58.443 g/mol.
1.9999 mol × 58.443 g/mol = 116.88 g
The spaceship does not have any gravitational pull. A spaceship can not produce its own gravity like Earth does.
6. V = IR= 1.2×100= 120 V
