Maria owns a bakery and bekes many different types of yeast breads. One day she notices that the bread she baked is flat and does not contain the air bubbles that are usually present. Which of the following would be a good explanation for what has
happened to her yeast
The yeast did not produce the carbon dioxide needed for the bread to rise.
The yeast were very active and produced too much energy
The yeast did not produce the alcohol needed for the bread to rise.
The yeast produced too much carbon dioxide.
Lo

you need to give more information

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
