Answer: 1×10^11
Explanation:
<u>concept to know:</u> scientific notation must be written in the form of a × 10^b
where 0<a<10.
100 billion= 100,000,000,000
there are 11 zeros after 1
1 × 10^11
Hope this helps!! :)
Answer:
The balanced reaction is this:
2 C₄H₁₀ (g) + 13 O₂(g) → 8 CO₂(g) + 10 H₂O (g)
Explanation:
Combustion is a chemical reaction whose reagents are oxygen, usually in excess and a hydrocarbon to generate carbon dioxide and water in the form of steam, as products.
Butane is considered as a reactant and it is a sort of alkane, in this case with 4 C (prefix but).
O₂ is needed for the complete combustion of butane.
1. Translate, predict the products, and balance the equation above.
Li + Cu(NO3)2 = Li(NO3)2 + Cu
2. How many particles of lithium are needed to produce 125 g of copper?
125 g Cu ( 1 mol / 63.55 g ) (1 mol Li / 1 mol Cu ) ( 6.022 x 10^23 particles / 1 mol ) = 1.18x10^24 Li particles
3. How many grams of lithium nitrate are produced from 4.83E24 particles of copper (II) nitrate?
4.83E24 particles of copper (II) nitrate ( 1 mol / 6.022x10^23 particles ) (1 mol Li(NO3)2 / 1 mol Cu(NO3)2 ) ( 130.95 g / 1 mol ) = <span>1043.77 grams Li(NO3)2</span>
Answer:
The compound which will precipitate first will be AgI with 
Explanation:
In order to precipitate a salt solution the ionic product of salt must exceed the solubility product.
Given:
Ksp of AgI = 
Ksp of PbI2= 
As Ksp of AgI is very low it will precipitate faster than lead iodide.
Now, higher the concentration of AgI solution taken faster its precipitation.
In the given choice the highest concentration solution of AgI is
