Answer:

<h3>it is hydrogen gas </h3>

3. the chemical equation is :

MgSO4 ( s ) + H2SO4 (aq)-->

MgSO4 (aq) + CO2 (g) + H2O (I)

THE IONISING OF H2SO4 IN SOLUTION IS CONPLEX

#A

Bubbles mean there is hydrogen gas popping up in tube.

#B

He should take a match stick and show it on the head of tube.If there is hydrogen it will be heared a popup sound and the flame will be over.

#C

Balanced equation given by

\\ \sf\longmapsto {2Mg\atop Magnesium}+{H_2SO_4\atop Sulphuric\:acid}\longmapsto {Mg_2SO_4\atop Magnesium \:sulphate}+{H_2\atop Hydrogen}

Which of the following solutions would have [Fe3+] = 0.020 M?
Shalnov [3]

Answer:

None of the given options

Explanation:

Let's go case by case:

A. No matter the volume, the concentration of Fe(NO₃)₃ (and thus of [Fe³⁺] as well) is 0.050 M.

B. We can calculate the moles of Fe₂(SO₄)₃:

  • 0.020 M * 0.80 L = 0.016 mol Fe₂(SO₄)₃

Given that there are two Fe⁺³ moles per Fe₂(SO₄)₃ mol, in the solution we have 0.032 moles of Fe⁺³. With that information in mind we <u>can calculate [Fe⁺³]</u>:

  • 0.032 mol Fe⁺³ / 0.80 L = 0.040 M

C. Analog to case A., the molar concentration of Fe⁺³ is 0.040 M.

D. Similar to cases A and C., [Fe⁺³] = 0.010 M.

Thus none of the given options would have [Fe⁺³] = 0.020 M.

1,5,25,125 what’s the pattern rule and extend by 3 more numbers
nika2105 [10]

For the first one the pattern is multiply the previous number by five as you see 1 x 5 = 5 and so on. To keep adding to it you would do

125 x 5 = 625     625 x 5 = 3125    3125 x 5 = 15625

Now for the second one the pattern is divide the previous number by three as you can see 2187 / 3 = 729 and so on. To keep going you would

81 / 3 = 27       27 / 3 = 9        9 / 3 = 3

I hope this helps you and if you have anymore questions i'll be  glad to answer them.
