2 mole Na needs 1 mole Cl2
4 mole Na = 2 mole Cl2
First, we write the reaction equation:
NiCO₃ + 2HBr → NiBr₂ + H₂CO₃
Now, writing this in ionic form:
NiCO₃ + 2H⁺ + 2Br⁻ → NiBr₂ + 2H⁺ + CO₃⁻²
(NiCO₃ is insoluble so it does not dissociate in to ions very readily)
Overall equation:
NiCO₃ + 2Br⁻ → NiBr₂ + CO₃⁻²
In areas where resistance is present, otherantimalarials<span>, such as </span>mefloquine<span> or atovaquone, may be used instead. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations.</span>
Answer:
ocean waves are converted to electricity with wave energy converter, or WEC, devices. ... The surface portion moves faster than the submerged part, and the WEC converts that relative motion into electricity
Answer:
The correct answer is beta decay
Explanation:
When a beta particle is emitted from a radioactive atom,at that time the daughter atom that is produced have atomic mass 1 unit more than that of its parental atom.
In the given reaction a beta particle is emitted from the carbon atom resulting in the formation nitrogen atom,The atomic mass of nitrogen atom is 7dalton which is one unit more than the atomic mass of carbon that is 6 dalton.
