Answer:
hi
Explanation:
chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Science the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
Volume = V = 250ml = 0.25 L
<span>M = 0.135M </span>
<span>Molar mass of AgNO3 = 108+14+3*16 = 170 </span>
<span>M = mole/V </span>
<span>mole = 0.135*0.25 = 0.03375 mole </span>
<span>mole = mass/molar mass </span>
<span>mass = 0.03375 * 170 = 5.7375 gr</span>
Answer:
Ionic bonds are made by a transfer of electrons. Covalent bonds are made by sharing electrons.
Explanation:
For ionic bonds, use the group number to help you determine how many electrons an element can give or receive (Group 1 gives 1 electrons, group 2 gives 2 electrons, group 3A gives 3, group 5A receives 3, group 6A receives 2, and group 7A receives 1).
Covalent bonds have to be worked out using the total number of valence electrons and the octet rule.
Sulfur dioxide(SO2)
Diphosphorus Pentachloride(P2Cl5)
Dinitrogen tetroxide(N204)
An ion is an atom with a net electric charge due to the loss or gain of one or more electrons.
An isotopeis each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.
