* "Viewing": While this could be understood in context, it's a bit vague. It's better to be more specific, like "After the viewing" or "After viewing the memorial."
* "Participate a ceremony": This is grammatically incorrect. You should use "participate in" or "attend" a ceremony.
* "Recognizes her passing": This is grammatically correct but could be more concise. Consider "honors her memory."
* "Celebrates life": This phrase is grammatically correct but could be more specific. Consider "celebrates her life."
Here are some corrected versions of the sentence:
* "After the viewing, we will attend a ceremony that honors her memory and celebrates her life."
* "Following the memorial, we will participate in a ceremony recognizing her passing and celebrating her life."
* "We will gather for a ceremony after the viewing, honoring her memory and celebrating her life."
These corrected versions use more specific language and proper grammar, making the sentence clearer and more impactful.
