Answer:

<u><em>The answer is</em></u>: <u>The chromosphere and the solar corona.</u>

<u />

Explanation:

<u>The chromosphere</u> <em>is the layer of the solar atmosphere located above the photosphere.</em> It is very faint and reddish in color when it becomes visible, <em>for a few seconds</em>, at the beginning and end of an eclipse of the Sun.

<u>The solar corona</u> <em>is the outer part of its atmosphere, which extends over a million kilometers, enters the interplanetary space and</em> can be observed in total eclipses of the Sun when the Moon covers the solar disk.

<u><em>The answer is</em></u>: <u>The chromosphere and the solar corona.</u>

Hydroelectricity and tidal energy are similar because
vovikov84 [41]

C.  both sources of energy rely on water.

Explanation:

Hydroelectricity and tidal energy are similar energy sources because they both rely on water.

They harness the power of moving water to produce their energy.

  • Tidal energy is the energy derived from moving water as crashing waves in an ocean.
  • Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
  • They are both renewable energy sources.

xenn [34]

Answer:Macaya (floruit 1802), was a Kongolese-born Haitian revolutionary military leader. Macaya was one of the first black rebel leaders in Saint-Domingue to ally himself with the French Republican commissioners Sonthonax and Polverel. He helped to lead forces that recaptured Cap-Français on behalf of the French Republicans.

Macaya was born in west-central Africa, probably in the Kingdom of Kongo, and taken to the French colony of Saint-Domingue as a slave. After the outbreak of the 1791 slave rebellion in northern Saint-Domingue, Macaya became a lieutenant of an elderly rebel commander named Pierrot. Pierrot's rebel forces were based in the hills outside of Le Cap (Cap Francaise), near Bréda plantation by 1793.

Consider the balanced equation below. 8H2 + S8 Right arrow. 8H2S Based on the mole ratios, what can most likely be predicted? 1
Arte-miy333 [17]

Answer:

8 mol of hydrogen will react with 1 mol of sulfur.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

8H2 + S8 —> 8H2S

Now, let us carefully observe the mole ratio of the reactants.

This is illustrated:

The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1

From the balanced equation above,

We can thus, concluded that:

8 moles of H2 will reacted with 1 mole of S8.

Hard water often contains dissolved Ca2 and Mg2 ions. One way to soften water is to add phosphates. The phosphate ion forms inso
MatroZZZ [7]

Answer:

mass of sodium phosphate required = 25.37 g

Explanation:

Equations of reactions:

3CaCl₂ + 2Na₃PO₄ ---> Ca₃(PO₄)₂ + 6NaCl

3Mg(NO₃)₂ + 2Na₃PO₄ ---> Mg₃(PO₄)₂ + 6NaNO₃

Number of moles of the ions = molarity x volume

Ca²⁺ : 0.052 M x 1.6 L = 0.0832 moles

Mg²⁺ : 0.093 x 1.6 L = 0.1488 moles

From the equations of reaction, number of moles of sodium phosphate required to react with each ion is given as;

For calcium: 2/3 x 0.0832 = 0.0555 moles

For magnesium: 2/3 x 0.1488 = 0.0992 moles

Total number of moles of sodium phosphate required = 0.0555 + 0.0992 = 0.1547 moles

Mass of sodium phosphate = number of moles x molar mass

molar mass of sodium phosphate = 164 g/mol

Mass of sodium phosphate = 0.1547 moles x 164 g/mol = 25.37 g

Therefore, mass of sodium phosphate required = 25.37 g
