I have no idea how to do this, any help would be appreciated
aksik [14]
Proton number = the atomic number (which is the smaller number
neutron number = the mass number (the bigger number) - the atomic number
number of electrons = the atomic number - the charge (it depends on the element but group 1 is +1 group 2 is +2 group 3 is +3 group five is -3 group six is -2 group seven is -1


i would solve the whole thing but its unclear hope this helps tho

Most _______ rocks form under conditions found a few kilometers under earths surface
12345 [234]
Most metamorphic processes takes place few kilometers below the Earth's surface. Thus, "metamorphic rocks" are formed under conditions found few kilometers under the Earth's surface.
Sedimentary rocks are formed by the compaction of sediments. Two main groups of sedimentary rocks are clastic sedimentary rocks and chemical sedimentary rocks.
Metamorphism refers to the changes in the mineral composition of the rocks. The three agents of metamorphism are heat, pressure and water.
The conversion of one form of rock to another is referred as rock cycle. In a rock cycle, an igneous rock formed from the deposition of molten magma can get converted into sedimentary rock when igneous rock breaks down into pieces and sediments. Finally, the any sedimentary rock or igneous rock can undergo metamorphosis to form metamorphic rocks. Metamorphic rock can again form igneous rock by melting of magma followed by crystallization.

A sample of nitrogen gas had a volume of 500. mL, a pressure in its closed container of 740 torr, and a temperature of 25 °C. Wh
iren2701 [21]

Answer:  Thus the new volume of the gas is 530  ml

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas =  740 torr

P_2 = final pressure of gas = 760 torr

V_1 = initial volume of gas = 500 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 25^oC=273+25=298K

T_2 = final temperature of gas = 50^oC=273+50=323K

Now put all the given values in the above equation, we get:

\frac{740\times 500}{298}=\frac{760\times V_2}{323}

V_2=530ml

Thus the new volume of the gas is 530 ml
