1 L ------- 1000 cm³
1.45 L ----- ???
1.45 * 1000 = 1450 cm³ ( volume )
Density = 0.710 g/cm³
mass = in Kg
m = D * V
m = 0.710 * 1450
m = 1029.5 g
1 Kg ------- 1000 g
kg -------- 1029.5 g
mass = 1029.5 / 1000
mass = 1.0295 Kg
hope this helps!
Answer:
Percent yield = 57%
Explanation:
Given data:
Number of moles of propane = 4.50 mol
Number of moles of carbon dioxide = 7.64 mol
Percent yield = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of propane and carbon dioxide.
C₃H₈ : CO₂
1 ; 3
4.50 : 3×4.50 = 13.5 mol
Percent yield:
Percent yield = actual yield / theoretical yield × 100
Percent yield = 7.64 mol / 13.5 mol × 100
Percent yield = 0.57× 100
Percent yield = 57%
<em>grou</em><em>p</em><em> </em><em>4</em><em> </em><em>,</em><em> period</em><em> </em><em>4</em>
Explanation:
from the electron configuration,
the element is Titanium
and it's has 22 electrons on it's shells , so wen you place it on the periodic table, you will see that it's in group 4 period 4
Answer:
Explanation:
Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity values generally increase from left to right across the periodic table. The highest electronegativity value is for fluorine.
