Sodium hydroxide (like soda)
Reason - has strong alkaline sodium hydroxide and hydrogen gas when reacted. This is an exothermic reaction-Sodium is heated and may catch on fire and burn with a orange flame.
Answer:
0.058 g of Al₂O₃
Explanation:
Al₂O₃ → Aluminum oxide
The molar mass is 101.96 g/mol. Therefore 1 mol (NA molecules) are contained in 101.96 grams
NA = Avogadro's number → 6.02×10²³
We make a rule of three to determine the grams we were asked for.
6.02×10²³ molecules are contained in 101.96 g
3.45×10²⁰ molecules will be contained in (3.45×10²⁰ . 101.96 g ) / NA = 0.058 g
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Answer:
P₂ = 450 kiloPascals
Explanation:
Boyle's law :))
P₁V₁ = P₂V₂
300*75 = P₂*50
P₂*50= 300*75
P₂ = 300*75/50 = 450
P₂ = 450 kiloPascals
<em>The weight has expanded because of pressure of gas.</em>
