Answer:
LIBs have had a huge impact on our society. They enabled modern portable electronics such as laptops and mobile phones. And they are now enabling clean and low-carbon transport, be it via electric cars or even flying taxis, and grid-scale storage of renewable energy
Explanation:
Answer:
1
Explanation:
N2 + 3H2 → 2NH3
From the above equation,
There are 2 atoms of N on both side of equation and also, there are a total of 6 atoms of H on both side of the equation. Therefore, the equation is balanced.
The coefficient of N2 is 1
The balanced equation for the burning of N-butane is;
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
stoi. ratio 2 : 13 : 8 : 10
molar mass 58 32 44 18
moles X 13 X/2 8X/2 10X/2
105.86 688.10 423.45 529.31
produced mass 18632.8 g 9527.6 g
moles of n-butane = X = 6.14 x 10³ g / 58 g mol⁻¹
hence other moles of compounds can be calculated.
Mass = molar mass * moles
mass fraction = mass / total mass
hence the mass fraction of
CO₂ = 18632.8 / 6.14 x 10³ = 3.03
H₂O = 9527.6 / 6.14 x 10³ = 1.55
the required mass of air = 688.10 x 32 = 22019.2 g = 2.20 kg
Answer:
A substance that can accept a hydrogen ion from another substance- a different type of base.
A substance that produces an excess of hydroxide ions (OH-) in aqueous solution- Arrhenius base
A substance that produces an excess of hydrogen ions (H+ ) in aqueous solution- Arrhenius acid
A substance that can donate a hydrogen ion to another substance.- a different type of acid.
Explanation:
Arrhenius defined an acid as any substance that produces hydrogen ion as its only positive ion when dissolved in water and a base as a substance which produces hydroxide ions as its only negative ion when dissolved in water.
This has informed the classification of definitions shown in the answer above.
