Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction:
kondaur [170]

Answer:

4 Fe + 3 O₂ → 2 Fe₂O₃

Explanation:

Let's start with the oxygen.

Reactants - 2

Products - 3

What number do 2 and 3 have in common? 6.

Put a 3 in the reactants and a 2 in the products to balance the oxygen.

Fe + 3 O₂ → 2 Fe₂O₃

Now let's look at the iron.

Reactants - 1

Products - 4

Put a 4 in the reactants to balance the iron.

4 Fe + 3 O₂ → 2 Fe₂O₃

The equation is balanced. Hope that helps.

Why do warmer and wetter biomes have higher net primary productivity
Andrej [43]
<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available In general, warmer and wetter biomes have higher net primary productivity than colder and drier biomes. The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>

Beginning with a cell that just fertilized ( 1 cell ) how many times must it divide to become a 64 cell blastomere ?
natka813 [3]

A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.

<u>Explanation:</u>

Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.  

The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation 2^n  where n is the number of divisions.  in the question it is given that the blastomere has 64 cells.

2^n=64  

n=6

This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
