I think that scientist should build a habitat we’re the endangered animals could go free.By scientists building a habitat I mean giving the endangered animals a space to feel safe.Another way scientists could help endangered animals , would be to try and reproduce, the animal.For example scientist could help out with giving the animals hormones to be able to reproduce.And lastly scientists could do experimentation on the endangered animals to see if the animal ever were to go extinct how they could reproduce a new species.

Explanation:
El elemento que tiene el número atómico 56 en la tabla periódica del bario. El bario es un elemento del grupo dos.
Se combina con el cloro para formar cloruro de bario. que tiene la fórmula BaCl2 de acuerdo con la valencia de ambos elementos.
El cloruro de bario es un compuesto iónico.
Answer:
Final concentration of C at the end of the interval of 3s if its initial concentration was 3.0 M, is 3.06 M and if the initial concentration was 3.960 M, the concentration at the end of the interval is 4.02 M
Explanation:
4A + 3B ------> C + 2D
In the 3s interval, the rate of change of the reactant A is given as -0.08 M/s
The amount of A that has reacted at the end of 3 seconds will be
0.08 × 3 = 0.24 M
Assuming the volume of reacting vessel is constant, we can use number of moles and concentration in mol/L interchangeably in the stoichiometric balance.
From the chemical reaction,
4 moles of A gives 1 mole of C
0.24 M of reacted A will form (0.24 × 1)/4 M of C
Amount of C formed at the end of the 3s interval = 0.06 M
If the initial concentration of C was 3 M, the new concentration of C would be (3 + 0.06) = 3.06 M.
If the initial concentration of C was 3.96 M, the new concentration of C would be (3.96 + 0.06) = 4.02 M
The answer is either number one or two.
