Answer:
Below are some patterns in the charge for elements in each group.
Group 1 elements : 1 valence electron and form ions with charge +1
Group 2 elements : 2 valence electrons and form ions with charge + 2
Group 3 elements : 3 valence electrons and form ions with charge + 3(there are some exceptions as well)
Elements in groups 4 and 5 are unpredictable also the D block elements consist of multiple oxidation states..
Group 6 elements : 6 valence electrons, form ions with charge -2
Group 7 elements: 7 valence electrons, form ions with charge -1
The octet rule is being followed, the elements form either ionic bond or covalent bond to fulfill it.
eg: when a K atom forms a K+ ion, the ion has the same electron configuration as the noble gas Ar (argon).
When an O atom gains 2 electrons to form the O²⁻ ion, the ion has the same electron configuration as the noble gas Ne (neon).
Note: Boron (B) is in Group 3 but doesn't form ions.
The shape of an igneous rock is based on the time it takes for the rock to cool. The quicker an igneous rock is formed, the smaller the rock is going to be. If an igneous rock cools down slowly, It will be larger. Therefore an igneous rock with large crystals cooled down slowly. Therefore the answer is choice 1.
Answer:
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
Explanation:
Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.
petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.
Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.
gas and oil are used to heat homes.
Hello!
The concentration of the final solution when a<span> chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water is
0,3 MTo calculate that, you'll need to use the dilution law, where initial and final concentrations are M1 and M2 respectively, and initial and final volumes are V1 and V2, as shown below.
Keep in mind that the final volume is the sum of the 200 mL of water and the 50 mL of H</span>
₂SO₄ that were added by the teacher. 
Have a nice day!
