2 CuO (s) + C (s) -> Cu (s) + CO2 (g) Im not sure if that's it but yeah
Answer: i hope it helps or not
A car increases it's velocity from 0 m/s to 14 m/s in 2 seconds. Amis - Omls ... A racing car's velocity is increased from 44 m/s to 66m/s in 11 seconds. ... 25 km/hr. 1200 km/hr. 2 min. - Kinlarise. 6. A car accelerates from a standstill to 60 km/hr in.
Explanation:
Ok so 40 percent of 3000 grams which is 3 kg is 1200 grams
So you would need 1.2kg or 1200 grams to make a 40% solution
When answering this question, you must consider the reactivity series. Mg is much higher than Zn in the reactivity series, therefore it can displace the Zn from the solution - displacement reaction.
It seems odd that you'd react Magnesium nitrate with zinc nitrate. Maybe you meant magnesium with zinc nitrate or vice Versa. Because in your case each compound would remain as it is as both Mg and Zn are happy in a relatively stable compound.
As for magnesium nitrate and magnesium nitrate, you cannot achieve a reaction between two substances that are the same. The same applies for Mg and magnesium nitrate. No displacement happens.
Hope it helps!
