Answer:

Atoms are the smallest particle that make up living <u>both</u><u> </u><u>living</u><u> </u><u>and</u><u> </u><u>non</u><u> </u><u>living</u><u> </u> things, they are made up of subatomic particles; protons, neutrons and electrons. Of these the electrons <u>protons</u><u> </u> and neutrons are in the nucleus and the protons <u>e</u><u>l</u><u>e</u><u>c</u><u>t</u><u>r</u><u>o</u><u>n</u><u>s</u><u> </u>orbit around the nucleus. Of the subatomic particles, the electrons have the largest <u>s</u><u>m</u><u>a</u><u>l</u><u>l</u><u>e</u><u>s</u><u>t</u><u> </u>mass and are negatively charged, the neutrons (negative charge) (<u>no charge)</u> and protons (positively charged) both have a relative mass of 1. Atoms contain an equal number of protons and neutrons <u>electrons</u>, so carry no overall charge. An element is a substance made up of only two <u>one</u> type of atom. Elements can be found in the Periodic table of elements, they usually have two numbers next to the chemical symbol, the larger number is generally the atomic <u>mass</u> number, which represents the number of neutrons and the number of protons. The smaller number is the relative atomic mass <u>atomic</u><u> </u><u>number</u> which represents the number of electrons or neutrons <u>protons</u>. In order to calculate the number of neutrons, you minus the atomic number from the relative atomic mass.

MakcuM [25]

The heat cause 300g water temperature increase from 20 to 26 celcius. The heat transferred would be: 300g * (26 °C -20 °C) *4.2 joule/gram °C= 7560J

The unknown substance is added to the water, so its final temperature should be the same as the water. The calculation would be:

7560J= 124g * (100-26)* specific heat

specific heat= 7560J / 124g / 74 °C= 0.8238 J/gram °C
