When does process of milk start

Marysya12 [62]

Answer:

Neutralization reactions

Explanation:

A neutralization reaction is a reaction between an acid and a base. Products of this type of reaction is water and a salt. The pH of the salt product would depend on how strong or weak the base and acid would be when they react with each other. Although the characteristics of bases and acids are practically polar opposites, when combined, they cancel each other our producing a neutralized product.

There are seventeen key nutrients essential for bone health. The ideal intake of calcium is approximately 1.75 g per day. How ma

baherus [9]

Answer:

2.63×10²² atoms

Explanation:

From the question given above, the following data were obtained:

Mass of calcium (Ca) = 1.75 g

Number of atoms of calcium (Ca) =?

From Avogadro's hypothesis,

1 mole of Ca = 6.02×10²³ atoms

Recall:

1 mole of Ca = 40 g

Thus,

40 g of Ca = 6.02×10²³ atoms

Finally, we shall determine the number atoms in 1.75 g of calcium. This can be obtained as follow:

From Avogadro's hypothesis,

40 g of Ca = 6.02×10²³ atoms

Therefore,

1.75 g of Ca = 1.75 × 6.02×10²³ / 40

1.75 g of Ca = 2.63×10²² atoms

Thus, 1.75 g of Ca contains 2.63×10²² atoms.

As you move down group one of the periodic table, what happens to the atomic radii? They increase, because of the higher number

Dennis_Churaev [7]

The correct answer is the atomic radius increase because of the higher number of occupied energy levels.

Atomic radius increases when going down a group. The valence electrons hold the higher levels because of the enhancing quantum number (n). As a consequence, the valence electrons get further away from the nucleus with the increase in n. The electron shielding inhibits these outer electrons from getting fascinated towards the nucleus. Therefore, they are held, and the resulting atomic radius is greater.

Why are phase changes horizontal on a heating curve

Marta_Voda [28]

Answer:

A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes.The second change of phase is boiling, as the temperature stays the same during the transition to gas.
