Calcium Hydroxide (Ca(OH)2) can actually be formed by the
reaction of Calcium Oxide (CaO) with water (H2O). The complete balanced
chemical reaction is:
<span>CaO + H2O
--> Ca(OH)2</span>
<span>The subscript 2 in (OH) means that there are 2 O and 2 H
on the product side. Hence, the equation is balanced already.</span>
I am not sure about .030 but i would pick c
.025) b
26)c
27)d
28)d
Carbon dating has<span> given archeologists a more accurate method by which they </span>can<span> determine the age of ancient artifacts. The </span>halflife<span> of </span>carbon 14<span> is </span>5730<span> ± 30 </span>years<span>, and the method of dating lies in trying to determine how </span>much carbon 14<span> (</span><span>the radioactive isotope of carbon) is present in the artifact and comparing it to levels</span>
