What is the answer?
mixas84 [53]

Answer:

Cranberry juice is a homogeneous mixture.  

Explanation:

Cranberry juice is a clear, red liquid. It is a homogeneous mixture, because you can't see a boundary between the water and the dissolved red substances dissolved in the water.

A is wrong. In oatmeal with raisins, you can tell the raisins from the oatmeal (see below).

C is wrong. Milk is a suspension of fat globules in an aqueous solution of other substances

D is wrong. Pepsi in an unopened bottle is a homogeneous, clear brown aqueous solution of carbon dioxide, high fructose corn syrup, and other substances.

Displacement Reactions involving Acids Reaction Observations (Before mixing) Both clear Classify Reaction (Select all that apply
Soloha48 [4]

A reaction in which heat is evolved is an exothermic reaction while a reaction in which heat is absorbed is an endothermic reaction.

In the first case; Na2CO3 + H2SO4, we can see that this is an acid - base reaction therefore it is a neutralization reaction. Since the tube was hot after reaction, heat is given off so it is exothermic.

In the second case; NaOH + H2SO4, we can see that this is an acid - base reaction therefore it is a neutralization reaction. We are told that the tube is not hot but we don't know the initial temperature of the tube or if it was colder than it's initial temperature so we can not make any inference regarding whether the reaction is endothermic or exothermic.

Lastly, the reaction, NaCl + HC2H5OH does not occur so we mark "no reaction". We are told that the tube is not hot but we don't know the initial temperature of the tube or if it was colder than it's initial temperature so we can not make any inference regarding whether the reaction is endothermic or exothermic.

warm air rises because of convection.

A student holds the back of his hand near an iron to see if it's hot. The heat transfer is conduction.

Warm water moves throughout a mattress because of ... why is there warm water in a mattress again? Convection, I guess.

In a swimming pool, the water near the surface is warmer because of convection and solar radiation; it's closer to the Sun than the bottom of the pool, so it receives more thermal radiation, making it warmer.

Read the statement. Magnesium atoms have 12 electrons, with the configuration 2-8-2. If the first five ionization energies of ma
Rashid [163]

The electronic configuration of magnesium is:

1s² 2s² 2p⁶ 3s² = [Ne] 3s²

This means that for a magnesium atom, in order to have its outermost orbital full, the easiest way would be to lose the two outermost electrons. This is seen in its relatively low first two ionization energies. The third ionization energy is several times higher because the ion would move from a stable form to an highly unstable form. (Mg⁺² → Mg⁺³ + e⁻).

Sodium only has one electron in its outermost orbital, so its first ionization energy would be several times lower than the second.
