Lavoisier is most noted for his discovery of the role oxygen plays in combustion. He recognized and named oxygen (1778) and hydrogen (1783), and opposed phlogiston theory. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. He predicted the existence of silicon (1787) and discovered that, although matter may change its form or shape, its mass always remains the same.<br></div><div><br></div><div><br></div><div>Ted</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Feb 12, 2023 at 6:42 PM Steve Isenberg <<a href="mailto:smisenberg@gmail.com">smisenberg@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif">Gentlepeople, especially any chemistry or physics experts:</span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif"><br></span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif">When I add 5 grams powdered fiber to almond milk, the added weight starts dropping immediately from 5 grams.<br></span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif"><br></span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif">Materials are powdered fiber supplement (Optifiber from Costco, wheat dextrin) and unsweetened almond milk (also from Costco).</span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif"><br></span></div><div class="gmail_default" style="font-size:small;color:rgb(11,83,148)"><span style="font-family:"comic sans ms",sans-serif">Procedure.
