Answer:
All matter is made up of tiny particles called <em><u>a</u></em><em><u>t</u></em><em><u>o</u></em><em><u>m</u></em><em><u>s</u></em><em><u>.</u></em> Atoms are made up of three subatomic particles known as <em><u>proton</u></em><em><u>,</u></em><em><u> </u></em><em><u>neutron</u></em><u> </u>and<em><u> </u></em><em><u>electron</u></em><em><u>.</u></em> Protons and neutrons are located in the <em><u>nucleus</u></em><em><u>.</u></em>
The nucleus is dense and takes up very little space within the atom. All protons have a <em><u>positive</u></em><em><u> </u></em>charge and have a mass of about 1 amu. All neutrons have no charge or are <em><u>neutral</u></em> and have a mass of about 1 amu.
Electrons are located in the area known as electron cloud. Electrons orbit around the nucleus and have a <em><u>negative</u></em> charge
.90 dL is 90 mL because 1 dL is 100 mL
Answer:
10 electrons will be present in an O2-
Explanation:
The atomic nucleus of oxygen contains 8protons and 8 neutron. It ionizes by gaining two more electrons making the total number of electrons in a doubly ionized oxygen to be 10 electrons.
(2) Adding more O2(g) would shift the equilibrium to the right because a higher concentration of oxygen is offered than its initial position, therefore more products have to be yielded to maintain equilibrium.
