..hydrochloric acid is hcl(g) in water...metals more reactive than hydrogen like Fe,Mg,and Pb reacts with Hcl to form salt and h2 gas...The salts dissolves in the water of the acid...Pbcl2 is insoluble in water as it accumulates around the lead and stops the reaction...so only Fe and Mg dissolve in hcl

[quote author=Aybalance post=66615315][/quote]..bro,how r u doing..how is ur prep? .
It is supported at one end..not both end...in my earlier post,av stated that at the pivot..the force is Zero...the total force acting is in the middle( at the centre)...try to visualize it...let's talk 2ru email l8ta...

pls what are my chances 255 for pharmacy

A ball is thrown vertically upwards from the ground with an intial velocity of 50m/s. What is the total time spent by the ball in the air (g=100ms-2). Please i need the working.

...thanks..I don't know that....

Hi doc...thanks for checking by...anything for us??

..gracy, thanks for quoting me but u could av just posted the ques....quoting me may nt allow others to solve it...there are many bosses and guru on this thread...

.....this is a very simple free fall question...we can calculate it in 2 ways....one is 2 step way and other is simple one step way( using formula)..let's do it d simple way first.... The time it spent in air is the time of flight represented as T....T= 2u/g......2 * 50/ 10 = 100/ 10... = 10s...

..the other way..the concept is DAT the same time it takes to move to the maximum height = the same time it takes to fall...total time t = t1 + t2...since t1= t2..total time = 2t1...to calculate t1(time to reach maximum height)...v= u+ at...v= u+ gt..At maximum height..v = 0...and since the motion of ball is against the force of gravity "g" is negative.. So 0= u - gt..u = gt..t=u/g...t= 50/ 10..t=5..t1= 5s.....since t( time of flight)= 2t1...t= 2 * 5s = 10s...

Have seen my mistake tanks alot. Please i couldnt find lamlard physics here in niger state but have gotten comprehensive & essential physics but i dnt like the english is there any i can use to complement them

You need to check the question again. How can g=100ms^-2?

thats where i got confused. It from comprehensive physics

Alright. Damayogenius18 has explained better.

The average velocity of a car is 54km/h. What is the distance covered if the time taken is 10s ? (a)200m (b)150m (c)100m (d)50m (e)25m. I need the working please

To convert 54km/h to m/s: (54*1000)/(60*60)=15m/s Average Velocity=distance/time Distance=15*10=150m

..correct bro..not doing too know o bt wanna point out a subtle correction...Average velocity = total distance/ total time taken.....not distance/ time...though it looks minor...has a long way to go...

green plants synthesized fats and proteins from the sugars which are the first products of photosynthesis. Nitrogen is needed to make protein. mineral salts cannot be made by plant. Hope have been able to demystify it.
