Answer:C. to protect themselves

D.

Explanation:When an animal closely resembles the color of its surroundings, it is known as protective coloring. The color of the animal helps the animal blend in with the environment and makes it harder for predators to see it. This protects the animal from predators.

Plz help asap What can you conclude about the iron(ii) and iron(iii) ions?
zavuch27 [327]

Answer:

The chemistry of iron is dominated by the +2 and +3 oxidation states i.e. iron(II) and iron(III) complexes e.g. Fe2+ and Fe3+ complex ions with selected ligands, usually of an octahedral shape, a few tetrahedral iron(III) complexes are mentioned too. The reactions of the aqueous ions iron(II) and iron(III) with ammonia, sodium hydroxide and sodium carbonate are described and explained as are complexes of iron(III) with the chloride ion and cyanide ion.

principal oxidation states of iron, redox reactions of iron, ligand substitution displacement reactions of iron, balanced equations of iron chemistry, formula of iron complex ions, shapes colours of iron complexes, formula of compoundsExplanation:

How does liquid carbon dioxide connect to organic chemistry <br> please I need long answers
inessss [21]
Carbon dioxide can’t exist in three states; Gas, Liquid & Solid. At normal temperatures and pressures, CO2 is colorless with a slightly pungent odor at high concentrations. If compressed and cooled to proper temperature the gas liquifies. Solid CO2, (dry ice) sublimates back to the natural gaseous state.

Which explains the change in ionization energy that occurs between removing the first and second electron from an Atom
Mars2501 [29]
 The ionization energy increases because the ratio of the protons to electrons increases. It is quantitatively expressed in symbols as X + energy → X+ + e−.

How many grams of nicl2∙6h2o will be used to prepare a 0. 0350 m, 500. 0 ml of nicl2 solution?
marin [14]

The mass of NiCl₂•6HO₂ needed to prepare a 0.035 M 500 mL solution of NiCl₂•6HO₂ is 4.165 g

<h3>What is molarity? </h3>

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NiCl₂•6HO₂</h3>
  • Molarity = 0.035 M
  • Volume = 500 mL = 500 / 1000 = 0.5 L
  • Mole of NiCl₂•6HO₂ =?

Mole = Molarity × Volume

Mole of NiCl₂•6HO₂ = 0.035 × 0.5

Mole of NiCl₂•6HO₂ = 0.0175 mole

<h3>How to determine the mass of NiCl₂•6HO₂</h3>
  • Mole of NiCl₂•6HO₂ = 0.0175 mole
  • Molar mass of NiCl₂•6HO₂ = 238 g/mol
  • Mass of NiCl₂•6HO₂ =?

Mass = mole × molar mass

Mass of NiCl₂•6HO₂ = 0.0175 × 238

Mass of NiCl₂•6HO₂ = 4.165 g

Thus, 4.165 g of NiCl₂•6HO₂ is needed to prepare the solution

NASA's Parker Solar Probe is currently en route to the outer corona of the sun. At its closest approach it will be traveling at
Digiron [165]

Answer:

120.822\frac{mi}{s} will be the speed in \frac{mi}{s}

Explanation:

This is a unit conversion problem.

To solve it, we need the equivalences between km and ft, ft and mi and hr and s.

The equivalences are :

5280 ft=1 mi\\1km=3280.84 ft\\1hr=60 min\\1min=60s

If 5280ft=1mi then

\frac{5280ft}{1mi}=1\\\frac{1mi}{5280ft}=1

The trick is to multiply by one the speed given until to convert it in mi/s units

(7.00).10^{5}\frac{km}{hr}.\frac{3280.84ft}{1km}.\frac{1mi}{5280ft}.\frac{1hr}{60min}.\frac{1min}{60s}=120.822\frac{mi}{s}

Notice that km,ft,hr and min have been cancelled.

Be careful of the fraction order.

Multiply by ft/km is different that multiply by km/ft
