The Reformed believe that the sacraments are a real means of grace in that they truly and physically represent God’s salvation to us. It confirms to those who truly believe that they are in a state of grace and can have assurance of salvation in this life.
The Reformed do not hold to a Roman Catholic concept of grace, which appears to be the presupposition behind these questions.
Define “means of grace.”
Are the sacraments salvific in any way? What is lost if one does not participate in baptism or communion?
We can therefore say, that in it the Lord displays to us all the treasures of his spiritual grace, inasmuch as he associates us in all the blessings and riches of our Lord Jesus. Let us recollect, then, that the Supper is given us as a mirror in which we may contemplate Jesus Christ crucified in order to deliver us from condemnation, and raised again in. order to procure for us righteousness and eternal life. It is indeed true that this same grace is offered us by the gospel, yet as in the Supper we have more ample certainty, and fuller enjoyment of it, with good cause do we recognise this fruit as coming from it.
As a Baptist we have communion in remembrance of our Saviour's sacrifice for us at Calvary. It is symbolic and does not impart Grace. If the Reformed believe communion imparts Grace this is an area where we differ.

I don't mean to come across as being snippy. It seems straight forward though, Communion and Baptism either are symbolic acts or they impart Grace to a believer.
