Answer:
If the reaction requires energy, it is often indicated above the arrow. A capital Greek letter delta (Δ) is written on top of the reaction arrow to show that energy in the form of heat is added to the reaction; hv is written if the energy is added in the form of light.
Answer:
Meteoroids are tiny asteroids or the broken-off crumbs of comets and sometimes planets. They range in size from a grain of sand to boulders 3 feet (1 meter) wide. When meteoroids collide with a planet's atmosphere, they become meteors
pls give me brainliest lol :)
Answer:
1.67 moles of N2 produce 2.5moles of NaN3
Explanation:
Equation of reaction:
2Na + 3N₂ → 2NaN₃
From the equation of reaction, 3 moles of N₂ produces 2 moles of NaN₃
How much is gotten from 2.5moles of 2NaN₃?
2 moles of N₂ = 3 moles of NaN₃
X moles of N₂ = 2.5 moles of NaN₃
X = (2.5 × 2) / 3
X = 1.67moles of N₂
1.67 moles of N₂ produces 2.5moles of NaN₃
Answer:
CH3COOH
Explanation:
that's the equation for acetic acid otherwise called ethanoic acid
And an endothermic reaction, always treat heat as a reactant
