Answer:

The correct answer is option C.

Explanation:

Atomic mass of iron =  55.845 g/mol

Atomic mass of oxygen = 15.999 g/mol

Mass of 1 mole of iron(III) oxide , Fe_2O_3:

2\times 55.845 g/mol+3\times 15.999 g/mol=159.687 g/mol

159.687 g/mol ≈ 159.70 g/mol

159.70 g/mol is the mass of one mole of iron(III) oxide.

If the atomic weight of nitrogen is 14.01, what is the mass of the nitrogen atoms in one mole of cadmium nitrate, Cd(NOÀ)
Nadya [2.5K]
The answer is 28.02.

The chemical formula for cadmium nitrate is Cd(NO₃)₂.

There are in total 2 nitrogen atoms in Cd(NO₃)₂. If <span>the atomic weight of nitrogen is 14.01</span>, the mass <span>of two nitrogen atoms in one mole of cadmium nitrate is 28.02:
2 </span>· 14.01 = 28.02

Which object can electrically polarized
kobusy [5.1K]

Answer:Static electricity works because objects which are otherwise "neutral" (in other words, objects with no net charge) can be polarized. An electric field, like one caused by a nearby charged object, can cause the charges inside of a neutral object — the protons and electrons — to move around a tiny bit.

How many electrons does carbon lack in its outer shell? biochemistry
tekilochka [14]
A neutral carbon doesn't lack any electrons. It has exactly the same number of electrons as it has neutrons.
However, it has four electrons in its outer shell in comparison with eight electrons for a noble gas.
In that sense, it needs four electrons to complete its second shell.<span />

What is the empirical formula for propene C3H6
USPshnik [31]

The empirical formula is the simplest formula attainable while maintaining the ratio so it will be CH2.

Explanation:

The empirical formula of a chemical compound is the simplistic positive integer ratio of atoms being in a compound. A simple example of this thought is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S2O2.
