  Let $R$ be a reduced real affine algebra of (Krull) dimension $d \ge 2$ such
that either $R$ has no real maximal ideals, or the intersection of all real
maximal ideals in $R$ has a height of at least one. In this article, we prove
the following: (1) the $d$-th Euler class group $\text{E}^d(R)$, defined by
Bhatwadekar-R.~Sridharan, is canonically isomorphic to the Levine-Weibel Chow
group of zero cycles $\text{CH}_0(\text{Spec}(R))$; (2) the universal Mennicke
symbol $\text{MS}_{d+1}(R)$ is canonically isomorphic to the universal weak
Mennicke symbol $\text{WMS}_{d+1}(R)$; and (3) additionally, if $R$ is a
regular domain, then the Whitehead group $\mathrm{SK_1}(R)$ is canonically
isomorphic to $\frac{\text{SL}_{d+1}(R)}{\text{E}_{d+1}(R)}$. As an
application, we investigate some Eisenbud-Evans type theorems.
