Answer:

The correct answer is 1 millon years.

Explanation:

Fossil rocks serve to study the evolution of species throughout history. Species usually adapt to survive the changing environment around them. Given this fact, we can deduce that the oldest species were very different from the way they are today. This means that the current species are more similar to those that preceded them more recently. The fossil of 1 million years ago is the most similar to today's horse.

Have a nice day!

seropon [69]
Upon a constant pressure (P), volume (V) of a gas will vary in direct proportion to changes in temperature (T). So V1/T1 = V2/T2
V2 = V1T2/T1 = (500)(300)/150
V2 = 150000/150 = 1000 mL

Perform the following conversion: 6.1 × 103 K (the surface temperature of the Sun) to °F and °C. Pay attention to the number of
Keith_Richards [23]

Answer:

\°C=5.8x10^3\°C

\°F=1.1x10^4\°F

Explanation:

Hello,

In this case, for the calculation of the temperature in degree Celsius we subtract 273.15 to the given temperature in kelvins:

\°C=6100-273.15\\\\\°C=5.8x10^3\°C

Next, by applying the following equation we compute it in degree Fahrenheit:

\°F=(5.8x10^{3}*9/5) + 32\\\\\°F=1.1x10^4\°F

Clearly, since the initial unit has two significant figures the computed units also show two significant figures.

Regards.

Llana [10]

Answer:

C₆H₅COOH Benzoic Acid

Explanation:

Here we are using the extraction method to separate  benzoic acid from naphtalene in the  ether solution  by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate  ( naphtalene remains in the organic layer )  .

The sodium benzoate  is completely soluble in the aqueous layer being a salt, and  reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid  since the it is insoluble in water hence  separating it.

Why would an atom with high electronegativity be a great match for an atom with low ionization energy?
nadezda [96]

Because the easier a metal donates an electron (Low Ionization Energy), the more readily a non-metal with high electromagnetically will accept it.  

Thus they match well, - one readily donates, the other readily accepts. This is how ionic bonding occurs.  

Hope this helps.
