Answer: 2.58L
Explanation:
We must convert the temperature from °C to Kelvin temperature
T1 = 40°C = 40 + 273 = 313K
V1 = 2.32 L
T2 = 75°C = 75 + 273 = 348K
V2 = ?
V1 /T1 = V2 /T2
2.32 / 313 = V2 / 348
Cross multiply to express in linear form
313 x V2 = 2.32 x 348
Divide both side by the coefficient of V2 ie 313. We have
V2 = (2.32 x 348) /313
V2 = 2.58L
Therefore, if the temperature is raised to 75°C, the volume of the gas will be 2.58L
The % mass/mass concentration of solute in the seawater sample is calculated as below
% mass = mass of the solute /mass of the solvent(sea water) x100
mass of the solute =1.295 g
mass of the solvent(sea water_) = 25.895 g
there the % mass = 1.295/25.895 x100 = 5.001 %
I think it is D but i'm not sure
hope I helped :)
The type of the bond is present Na₃PO₄ is the ionic bond. the Na₃PO₄ is the ionic compound. yes the Na₃PO₄ is the polyatomic ion.
The Na₃PO₄ is Na⁺ and PO₄³⁻. the phosphorus is the non metal and the oxygen atom is the non metal. the non meta and non meta form the covalent or molecular bond. the bond between the PO₄³⁻ bond is the covalent bond but the overall present in the Na₃PO₄ is the ionic bond . the bons in between the Na⁺ and PO₄³⁻ is the the ionic bond. the PO₄³⁻ id the polyatomic ion .
The bond between the positively charged ion and the negatively charged ion are called as the ionic bond and the compound form is the ionic compound.
