Answer:
Hey
You.
You emit infered light via heat.
The sun
The sun emits <em><u>all</u></em> frequincies of light, but mostly yellow light.
Your microwwaves
As your food gets hotter the microwwaves shake up the water molecules because they are the perfect frequincy to do so.

Answer:
Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M
Explanation:
Considering
Given that:
So,
<u>Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M</u>
Answer:
<em>C</em> H2SO4 = 9.79 M
Explanation:
- molarity (M) ≡ # dissolved species / V sln
- H2SO4 ↔ H3O+ + SO4-
∴ %w/w H2SO4 = 960% = g H2SO4 / g sln * 100
⇒ 9.6 = g H2SO4 / g sln
calculation base: 1000 g sln
⇒ g H2SO4 = 9600g
⇒<em> </em>mol<em> </em>H2SO4 =<em> </em>9600 g H2SO4 * ( mol H2SO4/ 980g H2SO4 ) = 9.796 mol H2SO4
⇒ V sln = 1000g sln / 1000g/L = 1 L sln
∴ ρ H20 ≅ 1000 Kg/m³ = 1000 g/L
⇒ <em>C</em> H2SO4 = 9.796 mol H2SO4 / 1 L sln
⇒ <em>C</em> H2SO4 = 9.796 M
