Are genders, race etc equal in Islam?

Are blacks and whites equal? Are women and men equal? By equal I’d say in terms of opportunity for reward or equal in terms of the mercy and love God has for them. I always had the idea that in Islam specifically men are superior to women and that Muslims are superior to other religions or that Arabs generally have it better than others. Are there any Quranic verses or anything that suggest otherwise for each of these categories?
