The balanced equation is as below
Na2CO3 +2 HCl → 2 NaCl +H2O + CO2
<u><em>Explanation</em></u>
step 1 : write the unbalanced chemical equation
that is Na2CO3 + HCl→ NaCl + H2O +CO2
Step 2: change the coefficient ( <em>number in front of chemical formula) </em>to make sure the number of atoms of an element are the same in both side.
By adding 2 in front of HCl and in front of NaCl balance the equation.
Therefore the balanced equation is as below
Na2CO3 +2HCl → 2NaCl +H2O +Co2
Answer:
i have the same paper im working on now taking me forever u got the answers?
Explanation:
Answer:
Explanation:
Based on the scenario being described it seems that this is due to the later ionization energies, namely the 2nd, 3rd etc... seem to be much higher than the first. Therefore this causes an excess amount of energy to be used in order to remove the electrons, thus causing less energy to be left after the process is over. This would be the best explanation for this behavior.
If egg is dipped in cylinder then the volume of egg will be difference in the volumes before dipping egg (initial volume) and volume after dipping egg (final volume)
Volume of egg= 58.5-50.0 = 8.5 mL
Hey there!
There are 6.022 x 10²³ atoms in one mole.
We have 2.50 moles.
2.50 x 6.022 x 10²³ = 1.51 x 10²⁴
There are 1.51 x 10²⁴ atoms of zinc in 2.50 mols of zinc.
Hope this helps!
