Q no 4=BeO is amphoteric and Q no 25 =electronic conifiguration of Mn is [Ar]3d5,4s2 so when it is in +3 state so its electronic configuration would become as [Ar]3d2,4s2....
PLZ Mam pmc revised common syllabus sy mcqs bnwai... With out excluded topics.....means jo topics syllabus mai include nahi hai usy chor dy. Aap k bari mehrubani hogi
Sir I solved pmc paid practice test or Jo 1st wala McQ hai wahan uska right option d hai or mujhe bhi d hi lag rha hai kindly Bata den right answer konsa hai ???
Mg is component of chlorophyll. So it is essential for leaf development
BeO is amphoteric in nature. Base with (HCl) and acid with ZnSO4
excuse me woo Be(OH) hay janab dakiye
Be is acidic in nature
Yeh method mujhy boht acha laga, mcqs practice may kafi helpful sabit hua😍😘
Same 👌👌💯
Oxides of berylium amphoteric
is k kafi mcqs out of syllabus hy plz syllabus se banaye q k syllabus mei. sirf trends poche gye hy
Beo is amphoteric in nature and this is absolutely confirm
yeah
Beo is amphoteric
Yes beo is Amphoteric
Yes
Magnesium necessary for development of leaf
Element which are very abundant in earth crust is ca and mg not si and al
No dear
Silicon is second most abundant and Aluminum is third most abundant in earth crust
@@Mirah168yes exactly
Bahooot khob Maza aya ❤❤
26?
27 mai tho c option hai
reason:large cation stabalize large anion
Nitrates of Na and K give different products not Li or Na
The oxide of BeO is amphoteric
Mam 33 ka A hoga
Bcoz down the group ionic character increase hota ha aur coveland character decrease hota ha
Kia ye mcqs Sindh agriculture uni or gcuh me askte hn mdcat K ilawa plzz tell me
Kindly doosaray chapter k b banayay..
Especially organic chemistry k ..
Hn ak batt national mdcat New syllabus k mutabik banayay... thanks
oxides of BeO are amphoteric in nature not acidic.Please confirm it
No BeO is purely acidic in nature
Out of 40 mcqs i correct only 32
mam ques no 3 may B hay agar app janna chahtay hu jab group 2A start hooga Ru ye waha par wazih hay

mcq 20 ka exact answer 2000C ha or us ky mutabik to hmy in options ma sy 2500C select krna chaye
Q no 4=BeO is amphoteric and Q no 25 =electronic conifiguration of Mn is [Ar]3d5,4s2 so when it is in +3 state so its electronic configuration would become as [Ar]3d2,4s2....
No correct option D he hai
2 S orbital se jaienge or 1 D se
4 = C it act as both acid or base
Most abundant in earth crust mg and ca
dear most abundant in earth crust oxygen
2nd most abundant silicon
BeO is an amphoteric oxide
mam beo is amphoteric according to book plz confirm it
Yes amphoteric
Jazak Allah mam
Beryllium is amphoteric not acidic
Ye to outof syllabus he n pmc ke learning objectives me toh sirf properties prhni hai na or trends ???

Beo is ampoteric in nature.this mcqs is so reapted in etea .I am highlight this mcqs in chemistry book.
Yeah its amphoteric
But Google ma acidic lika ha
Can you tell me the explanation of mcq 26?

Plzz mam upload the one other video of p block for more practice
sure, we will upload
LiOH is least ionic in nature
Beo is amphoteric in nature

Abundant elements Ca and Mg hai ya Si and Al?
si and Al
Plzzzz upload videos for organic chemistry
mam kia ye mcques common syllabus se bnaye hain????
Bilkul nii😆😂
@@rubabbatoolqureshi1442 KAASH COMMON SYLLABus pta hota
Mam Beo is amphoteric and Mg is required for leaf beacause it present in chloriphyll
mcq 12 answer should be B

be is amphoteric
12 B
Question 38k magnesium h
Mcq nmbr 12 main option B correct hain, Q k Na atomic nmbr 11 hain .
But it is sodium + 1 it's mean lose one electron and having electronic configuration 10
Someone please explain mcqs 17

Basic
jb metal oxide ka water ky sath reaction krwaty hn to hydroxides ki formation hoti ha iss liyay ye basic hoty hn.......
