Answer:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂ . . . . . balanced combustion reaction
C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂ . . . . not balanced
The two reactions involving Ca are not combustion reactions.
The number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)
In order to determine volume (number of liters) one can make from 470 milligrams of table salt (NaCl)
First, we will convert the unit of concentration to grams per liter or grams per milliliter
From the question, the desired concentration is 0.90% NaCl (9 grams of salt per 1000 grams of solution)
Since the density of the NaCl solution is 1.0 g solution/mL solution, then
9 grams of salt per 1000 grams of solution means 9 grams of salt per 1000 mL of solution.
From the question, mass of the table salt = 470 milligrams = (470/1000) grams
∴ Mass of the table salt = 0.47 grams
Now,
If there are 9 grams of salt per 1000 mL of solution
Then, there will be 0.47 grams per mL of solution
∴ mL
mL
mL
mL
∴ There will be 0.47 grams per 52.22 mL of solution
Hence, the number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)

Answer:
2.7g/cm³
Explanation:
Given parameters:
Dimension of the aluminum = 10.5cm x 10.5cm x 0.1cm
Mass of the aluminum = 29.8g
Unknown:
Density = ?
Solution:
Density of a substance is its mass per unit volume;
Mathematically;
Density =
Volume of the aluminum = 10.5cm x 10.5cm x 0.1cm = 11.025cm³
So, insert the parameters and solve;
Density = = 2.7g/cm³
