Leona is making lemon pudding from "scratch." her ingredients include fat-free milk, corn starch, lemon juice, egg yolks, salt, sugar, and butter. when she added some of the ingredients together, little clumps formed in the mixture before she could heat it. what happened to those ingredients?

She added the ingredients in the wrong order, this will make the ingredients to mix in a different way and that can lead to different errors, formation of clumps is one of them.

Explanation:

The acid present in the lemon will react with the protein from the milk so it will clabben it forming this little clumps. It could be also the Corn Starch that will not dissolve correctly if add all in a go, due to the polarity.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
