Answer:
The molar mass of Gallium Sulfite is 379.6356
Explanation:
Molar Mass can often be found on the periodic table, however, this is specific to single elements. You can however find the molar mass by dividing the mass(g) by the amount of substance(mol).
Answer:
2 dozen of H₂ particles + 1 dozen of O₂ particles → 2 dozen of H₂O particles.
Explanation:
- For the reaction of water formation:
<em>2H₂ + O₂ → 2H₂O.
</em>
- It should apply the the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.
<em>So, every 2.0 moles of H₂ react with 1.0 mole of O₂ to produce 2.0 moles of H₂O.</em>
<em></em>
<em>So, the represented reaction of the problem is:</em>
2 dozen of H₂ particles + 1 dozen of O₂ particles → 2 dozen of H₂O particles.
Answer:
Explanation:
Hello,
At first, it turns out convenient to compute the total moles of sodium that will be dissolved into the solution by considering the added amounts of sodium bromide and sodium sulfate:
Once we've got the moles we compute the final volume via:
Thus, the molarity of the sodium atoms turn out into:
Now, we perform the same procedure but now for the bromide ions:
Finally, its molarity results:
Best regards.
Answer:
Siδ⁺ -- Pδ⁻⁻
Clδ⁻⁻ -- Pδ⁺
Siδ⁺ -- Clδ⁻⁻
Of the mentioned bonds the most polar bond is Si -- Cl
The polarity of the bond primarily relies upon the electronegativity difference between the two atoms that forms the bond. Therefore, if the electronegativity difference between the two atoms that forms the bond is more the bond will be more polar, and if it is less then the bond will be less polar. The electronegativity of the atoms mentioned is Si = 1.8 , P = 2.1 and Cl = 3.00.
Therefore, the Si - Cl atoms exhibit more electronegativity difference, thus, the Si - Cl bond will be the most polar bond.
Explanation :
It is given that,
Speed of the proton, 
Magnetic field, 
Magnetic force is given by :
q is the charge of proton, 
So,
The direction of force is given by using right hand rule. So, the force will act in upward direction.
Hence, the correct option is (a) " 
to the north".
