solar wind: gives comets their tail
solar flares: a big explosion on the surface of the sun
sunspots:every 11 years there is a peak in the number of them
2. 0.05733 mol CuCl2 (1 mol Cu(OH)2 / 1 mol CuCl2) = 0.05733 mol Cu(OH)2 <-- It's the same because there's a 1:1 ratio between the reactant and the product.
Answer: B
Explanation: The figure below shows the dot and resonance structure of ozone and the structures.
Answer:
Mass of arsenic chloride produced is 0.363 g
Explanation:
Given data:
Mass of arsenic chloride produced = ?
Mass of arsenic react = 0.150 g
Mass of chlorine = excess
Solution:
Chemical equation:
2As + 3Cl₂ → 2AsCl₃
First of all we will calculate the number of moles of arsenic.
Number of moles = mass/ molar mass
Number of moles = 0.150 g/ 75 g/mol
Number of moles = 0.002 mol
Now we will compare the moles of arsenic with arsenic chloride.
As : AsCl₃
2 : 2
0.002 : 0.002
Mass of arsenic chloride produced:
Mass = number of moles × molar mass
Mass = 0.002 × 181.28 g/mol
Mass = 0.363 g
