First of all, this is not how you buy memory. Memory should ALWAYS be purchased in kits that contain the full amount of memory you wish to run. Buying multiple kits, even if they are the same model, is asking for trouble.
Please read BOTH the section titled "Mixed memory (Or the odd man out)" at the following link in section II.
In the beginning, there was......BIOS Before you go ANY further, go to the manufacturer product page for your specific motherboard model AND revision. Revision is an important aspect because for any given motherboard there may be more than one version of that model which will be identified...
And this post, which further addresses the issues of using multiple memory kits. This should give you a better understanding of why you don't want to buy two separate sticks, but instead buy ONE kit that comes with MATCHED sticks in the same kit.
As to the memory being "compatible", it also depends highly on what CPU model is in use. AMD Ryzen platforms have wildly different memory support even on the same board depending on the CPU model so knowing that would be a requirement to even make a guess. Right up front I'll tell you that you should not be extremely hopeful about any Corsair Vengeance memory kit working well with any of the Ryzen platforms, especially if it is 3xxx series or older. Even on the 5xxx series like your 5600x it might be hit or miss.
I would highly recommend sticking to something more broadly compatible like the G.Skill Ripjaws series because even when the QVL says a given Vengeance kit is compatible a lot of users STILL have problems with them. For this kit, neither the Corsair memory finder NOR the motherboard QVL show the CMW32GX4M2D3600C18 memory kit being compatible with your B550M-Plus WiFi.
