Rabbits are eaten by predators such as foxes and wild dogs. If rabbit number decline predators ( foxes ) compete for the rest of the resources in forest. This is the competition between the members of same species or : interspecific competition. Foxes compete for the same resource ( rabbits ).
Answer: Interspecific competition.
Letter d, because they are both alkali metals (group one)
First step is to balance the reaction equation. Hence we get
P4 + 5 O2 => 2 P2O5
Second, we calculate the amounts we start with
P4: 112 g = 112 g/ 124 g/mol – 0.903 mol
O2: 112 g = 112 g / 32 g/mol = 3.5 mol
Lastly, we calculate the amount of P2O5 produced.
2.5 mol of O2 will react with 0.7 mol of P2O5 to produce 1.4
mol of P2O5.
This is 1.4 * (31*2 + 16*5) = 198.8 g
The statement that describes a chemical reaction is the statement c. reactants form products when atoms are rearranged.<span> The atoms of the reactants are arranged is a specific position and number forming a determined compound. In a chemical reaction, the products are different compounds than the reactants, so the atoms have to rearrange to form these new compounds (the products).</span><span />
