Answer: Homogeneous mixtures : food coloring dissolved in water, a cup of tea and sugar :
Heterogeneous mixtures : food coloring dissolved in water, a cup of tea and sugar
Explanation:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.
There is no physical boundary between the dispersed phase and dispersion medium. Example: peanuts and almonds mixed together in a bowl, a bucket full of sand and gravel
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.
There is a physical boundary between the dispersed phase and dispersion medium. Example: food coloring dissolved in water, a cup of tea and sugar
Answer:
0.642 g
Explanation:
La ecuación balanceada es:
- 2Mg + 2CuSO₄ + H₂O → 2MgSO₄ + Cu₂O + H₂
Primero <u>convertimos 1.89 g de Cu₂O en moles</u>, usando su <em>masa molar</em>:
- 1.89 g ÷ 143.09 g/mol = 0.0132 mol Cu₂O
Después <u>convertimos moles de Cu₂O en moles de Mg</u>, usando los <em>coeficientes estequiométricos</em>:
- 0.0132 mol Cu₂O *
= 0.0264 mol Mg
Finalmente <u>convertimos moles de Mg en gramos</u>, usando la <em>masa molar de Mg</em>:
- 0.0264 mol Mg * 24.305 g/mol = 0.642 g

Answer:
I think third C12/hv is right answer
Answer:
The carrying capacity of this population would be 125 we know this because we see that this number occur multiple times and seems to be the tipping point after which the number of the population always go down
