Jus a quick question isn't it 10g of ca Because Ca+h20= Ca(OH)2 + h2 And balanced it's Ca+ 2H2O -> Ca(oh)2+H2 The equation 40g of ca->36gh20 X ->9gh20 X=10gof ca
I'm not good in chemistry... but am just curious on the h This part.... How can the number of moles of hydrogen (0.8 an element) in methane(0.2 a compound) be greater than number of the number of moles of a compound containing two different elements? So if we were to calculate the number of moles of carbon in methane and add it to the number of moles of hydrogen are we going to get 0.2 which is the number of moles of methane?
Ur teaching is quite unique sir❤️🙏but wen ever u are about to teach a topic u shud be making sure u tackle everything in it coz u just have done the 40 percent of mole concept not a full topic
1. X=20g of Ca
2.x=16moles of NH3
thank you so much sir
Your teaching is splendid
I love it
My God continue to bless you
AMEN 🙏

You are not called to be a teacher of chemistry but you are born to
Am really humbled 🙏 💓
Good teacher thank you so much sir
Thank you sir
Keep up with the good work Sir
I think I have found the science teacher I was looking for you are the best thanks
For science Tuitions WhatsApp 0971066747
How much per month
I have never seen such a great teacher like you
Wow am blessed to find this man elo on Wednesday am writing 🙏🙏🙏
Sir you're the best. From the day I learnt about mole concept I never understood until I came across your channel. I shall testify 🙏❤
Thanks so much
This really helps me to understand stoichiometric, cheers 🥂 Sir.🙏🙏🙏
Who watched this video before writing the science p2? This really helped ❤
You're just a wonderful teacher finally l have understand mole concept🙏🙏
you are the best teacher very clear and loud
Powerful explanation sir... May the good Lord bless you abundantly🎉🎉🎉
The best tutor of all time, a distinction waiting for me
Sure Exactly Stay Connected
@@HarrisonjzuluTutor I will always, help me out with organic chemistry
Really you are a teacher of science 💯💯💯☝️
Thanks so much
This is powerful, keep it up we are enjoying your work. God bless your work and life
Continue with your spirit You have Mr.
You make everything simple sir never thought will understand this topic thank you so much
Thanks so much am humbled too
I love your teaching
This is the teacher I waited for
Thanks so much ❤️
Well explanation sir thank you.
Wow this is great step by step very understanding
Thank you I really enjoyed learning🙏
Great sir work Sir... I found the Same answer by dividing 3.2/4. Coz the molar mass for H in this case is 4.
Have really enjoyed your teaching ❤
You help a lot may God bless you
AMEN 🙏🙏
U are a best one God bless you
❤ am enjoying your work
U are really helping me sir thank you very much may God bless you
Thank you so much sir you are the best

Have u done limiting reagents, if not do a video.
Excellent ❤
Do about percentage purity
You are doing better
Thank you 😊😊
Yeessss sir woohoo great job 😊👏👏
Thank u sir God bless you
Thank you sir❤❤❤❤
Thanks sir do also acids bases and salt
Ok noted I will do it 🥰🥰
you are a best teacher, but I need your help in chemistry, biologyand physics am a science student
This is well explained..
Thank you sir.
Thank you so much 🥰
Thank you Sir you have done it
Thank you very much sir
You are welcome ❤️🥰
Very clear.
You are welcome
Thank you ✍️✍️✍️✍️
Very impressive
You also define mole has this is the measurement of units represented by 6.02 x 10²³ of particles of atoms of molecules
Thank you so much I understand now
❤❤❤wonderful

You are a good person
Thanks so much 🙏
You’re welcome 😊
Now NaCl doesn,t have that Cl2 here
Thank you sir
Thanks alot
Can you please give the answers for the homework
We already uploaded on this same channel
Best of the best
Thanks so much
You're the best
Awesome
Interesting😊
Thanks so much ❤️
