Can someone help. posted this same question 3-4 times. Alina wants to make some yummy sugar cookies. The recipe written in her book is: 2 3/4 cup flour + 1 cup butter + 1 1/2 cup sugar + 1 egg + 1 tsp baking soda + 1/2 tsp baking powder = 24 cookies But Alina has the following ingredients in her kitchen: 9 cups flour, 5 cups butter, 4.5 cups sugar, 8 eggs and a excess of baking soda and powder. 1. How many cookies can she make? 2. Which ingredient is her limiting reactant? 3. Besides, baking soda and powder, how many of each reactant will be left over in her kitchen?

(JSYK: this is all considering that only whole batches are included and fractional batches aren't)

3 batches (72 cookies), her limiting reactant should be sugar since she only has enough to make three batches exactly, and she will also have 3/4 a cup of flour left over, 2 cups butter, and 5 eggs, in addition to the excess of baking soda and baking powder.

Hope this helps, if not, comment below please!!!

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the answer is na (sodium)
