Answer:
Cream butter and sugar. Beat in eggnog, baking soda and nutmeg. Gradually add flour and mix well. Cover and chill 1 hour. On a lightly floured surface, roll out half of the dough to 1/8-in. thickness. Using floured 3-1/2-in. cookie cutters, cut into desired shapes; place on ungreased baking sheets. Repeat with remaining dough.
Explanation:
eggnog crumble cookies they are so good
Explanation:
where's the question, please?
List of the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) is below,
Here , we have to list the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) and have to identify the group numbers of these metals.
- Hydrogen H+
- Lithium Li+
- Sodium Na+
- Potassium K+
- Rubidium Rb+
- Cesium Cs+
- Beryllium Be2+
- Magnesium Mg2+
- Calcium Ca2+
- Strontium Sr2+
- Barium Ba2+
- Aluminum Al3+
- Zinc Zn2+
- Scandium Sc3+
- Silver Ag+
Co is stable in both +2 and +3 oxidation state. So it can variable. Li only have +1 charge. So it is invariable from one compound to other.
