Student or Learner
I recently joined this forum and I need help with some grammar.
1. A has been recently created and it shows good electrical performance. ( In this sentence, both present tense: shows and present perfect tense: has been, are used. Is this sentence correct?)
2. For chemistry vocab, "compounds are all stoichiometric" , is this sentence correct?
I would really appreciate your help
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Thank you for your answers.
What I wanted to ask for the first question is
A substance has been recently created and it shows good electrical performance.
In that sentence, both present perfect tense and present tense are used. Is this right sentence?
