Hey there!
AlCl₃ + NaOH → Al(OH)₃ + NaCl
Balance OH.
1 on the left, 3 on the right. Add a coefficient of 3 in front of NaOH.
AlCl₃ + 3NaOH → Al(OH)₃ + NaCl
Balance Cl.
3 on the left, 1 on the right. Add a coefficient of 3 in front of NaCl.
AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl
Balance Na.
3 on the left, 3 on the right. Already balanced.
Balance Al.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation: AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl
Hope this helps!
Answer:
It is called Sulfur dichloride
Answer:
4000 L
Explanation:
Step 1:
Data obtained from the question. This include the following:
Initial volume (V1) = 2000 L.
Initial temperature (T1) = 100 K.
Initial pressure (P1) = 100 kPa.
Final temperature (T2) = 400 K.
Final pressure (P2) = 200 kPa.
Final volume (V2) =..?
Step 2:
Determination of the new volume of the gas.
The new volume of the gas can be obtained by using the general gas equation as follow:
P1V1/T1 = P2V2/T2
100 x 2000/100 = 200 x V2/400
Cross multiply to express in linear form.
100 x 200 x V2 = 100 x 2000 x 400
Divide both side by 100 x 200
V2 = (100 x 2000 x 400)/(100 x 200)
V2 = 4000 L
Therefore, the new volume of the gas is 4000 L
Only in case if there are impurities are present in other sample of that substance.
Answer:
Copper sulphate is an acidic salt: It is the product of the reaction between a weak copper base and a strong acid , H2SO4
Litmus has a red colour in acidic solutions:
Conclusion: Acidic copper sulphate solution turns blue litmus to red
Baking soda is a basic salt : It is the reaction product of a weak acid , CO2 and a strong base , NaOH
Litmus has a blue colour in basic solutions:
Conclusion: basic baking soda solution turns red litmus to blue
