Since protons are postive and neutrons are neutral. Then it is postive.
Answer is: c) CH₄.
<span>Average speed is inversely proportional to the molar mass, ligher molecules travel faster. Calculate molar mass of all molecules:
a) M(O</span>₂) = 2·16 = 32g/mol.
b) M(N₂) = 2·14 = 28 g/mol.
c) M(CH₄) = 12 + 4·1 = 16 g/mol.
d) M(SF₆) = 32 + 6·19 = 146g/mol.
e) M(CO₂) = 12 + 2·16 = 44g/mol.
Answer:
ionic, BRAINLIEST PLZ
Explanation:
ionic is slightly charged particles, and absorbing an o atom creates a slight negative charge, there are no shared atoms, so it is not covalent, and the other two are just add ons
The sun heats up the atmosphere at the equator. The dense water sinks under and forms deep water masses under the ocean current. Then it gets wind due to the air current and this brings currents at the surface if the ocean.
The concentration of a dextrose solution prepared by diluting 14 ml of a 1.0 M dextrose solution to 25 ml using a 25 ml volumetric flask is 0.56M.
Concentration is defined as the number of moles of a solute present in the specific volume of a solution.
According to the dilution law, the degree of ionization increases on a dilution and it is inversely proportional to the square root of concentration. The degree of dissociation of an acid is directly proportional to the square root of a volume.
M₁V₁=M₂V₂
Where, M₁=1.0M, V₁=14ml, M₂=?, V₂=25ml
Rearrange the formula for M₂
M₂=(M₁V₁/V₂)
Plug all the values in the formula
M₂=(1.0M×14 ml/25 ml)
M₂=14 M/25
M₂=0.56 M
Therefore, the concentration of a dextrose solution after the dilution is 0.56M.
