Answer:
B
Explanation:
conduction is the transfer of heat between objects that touch
Answer:
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
Use the ideal gas law PV = nRT and manipulate it to solve for n. PV/RT = n.
Convert to SI units:
660ml -> 0.660 L
27 degrees -> 300 K
Leave Pressure as is
Use 62.36368 for R becuase you are using mmHg for Pressure.
Now plug into the equation to get about 0.025928 mols. Divide the 3.30 grams by the mols to get about 127 g/mol.
False because they both have different properties
25
There are 25 protons in an atom of Mn-51 even if the atom has a charge of +1. The proton number also defines the atomic number of an atom.
Explanation:
The proton number of the atoms of an element never change without changing the type of atom/ element. Therefore, in other words, the atomic number (which is equivalent to proton number) remains the same across all isotopes of an element. Even when the atoms lose some electrons, the proton number remains the same.
Manganese (Mn) has atomic number 25. Meaning it has 25 protons. This proton number remains the same even if the Mn atoms are charged.
