Explanation:
Copper has an atomic number of 29, so it contains 29 protons and 29 electrons. ... The atomic weight of copper is 64; it has 29 protons and 35 neutrons.
I think the correct answer from the choices listed above is option A. It is by the process of photosynthesis that would help counteract with human interactions. The carbon dioxide emitted by human activities can be used by this process to produce more oxygen.
Answer:
C6H14O3F
Explanation:
The first step is to divide each compound by its molecular weight
Carbon
= 39.10/12
= 3.258
Hydrogen
= 7.67/1
= 7.67
Oxygen
= 26.11/16
= 1.63
Phosphorous
= 16.82/31
= 0.542
Flourine
= 10.30/19
= 0.542
The next step is to divide by the lowes value
3.258/0.542
= 6 mol of C
7.67/0.542
= 14 mol of H
1.63/0.542
= 3 mol of O
0.542/0.542
= 1 mol of P
0.542/0.542
= 1 mol of F
Hence the molecular formula is C6H14O3F
Answer:
1) synthesis MgI2
2) double replacement CuS + (HCl)2
3) double replacement, not sure ab the formula sorry
Answer:
Magnetic property
Explanation:
Iron filling is a magnetic compound, unlike the salt crystals. This means they are attracted by magnets.
To separate a mixture of iron filling s and salt crystals, a magnet should be used to remove the iron fillings from the mixture.
