Answer:
6.12 L
Explanation:
Given that,
Initial volume, V₁ = 5 L
Initial temperature, T₁ = 7.0°C = 343 K
Final temperature, T₂ = 147°C = 420 K
We need to find its new volume. The relation between volume and temperature is given by :
So, the new volume is 6.12 L.
<span>You are given O2 and C3H8, this is a combustion
reaction. The chemical reaction is C3H8 + 10O2 à 3CO2 + 4H2O. You are also given the molar mass
of O2 which is 32.00 g/mol and C3H8 which is 44.1 g/mol. You are required to
find the mass of O2 in grams. Since you have the reaction, oe mole of C3H8 is
required to completely react 10 moles of O2. So,</span>
0.025g C3H8(1 mol C3H8/44.1 g C3H8)(10 mol O2/1
mol C3H8)(32 g O2/1 mol O2) = <u>0.1802 g O2
</u>

Answer:
Number of mole in H2O = 5.4 moles
Explanation:
Given:
Mass of H2O = 97.3 gram
Find:
Number of mole in H2O
Computation:
We know that molar mass of H2O = 18 g/mole
So,
Number of mole = Given Mass / Molar mass
Number of mole in H2O = Mass of H2O / Molar mass of H2O
Number of mole in H2O = 97.3 / 18
Number of mole in H2O = 5.4055
Number of mole in H2O = 5.4 moles
Answer:
More electronegative element in each pair
O & F ⇒ Fluorine is more electronegative.
O & Br ⇒ Oxygen is more electronegative.
O & S ⇒ Oxygen is more electronegative
O & N ⇒ Oxygen is more electronegative
O & P ⇒ Oxygen is more electronegative
O & K ⇒ Oxygen is more electronegative
O & Ca ⇒ Oxygen is more electronegative
Explanation:
Electronegativity is the measure pf tendency to attract bond pair electrons towards itself in a covalent bond.
More electronegative element attract bond pair electron from less electronegative element.
Electronegativity increases along the peroid when we move from left to right in perodic table and decreses down the group or top to bottom in periodic table.
So Oxygen, Fluorine, Chlorine and Nitrogen are the most electronegative among the all elements in periodic table.
