Answer:

The ones with 8 protons

Explanation:

Since there are two of them with 8 protons, we can assume they are the same element. The first 8 proton element has 10 neutrons while the second has 11. This makes them isotopes of one another

The puppies have different colored noses because of reccesive and dominant genotypes.

Genotypes are represented by letters, capital being dominant and lowercase being recessive.

For example, lets say t = pink nose and T = black nose.

If the parents have black noses, then they will pass on T genotypes.

But, they also have hidden pink nose genotypes.

These hidden genotypes are passed on to the puppies, one of the puppies gets more black nose genotypes.

If a puppy gets tt, they will have a pink nose.

If they get TT, they will have a black nose

If they get Tt, they will also have a black nose.

Because the black nose is dominant, its more likley for the puppies to end up with a black nose.

How many grams of solute are dissolved in 125.0 mL of 5.00 M NaCl (MM = 58.45)?
Nookie1986 [14]

Answer: 36.53g

Explanation:

First we need to find the amount of NaCl that dissolves in 1L of the solution that produced 5M of NaCl

Molarity = 5M

MM of NaCl = 58.45

Molarity = Mass conc (g/L) / MM

Mass conc. (g/L) of NaCl = Molarity x MM

= 5 x 58.45 = 292.25g

Next, we need to find the amount that will dissolve in 125mL(i.e 0.125L)

From the calculations above,

292.25g of NaCl dissolved in 1L

Therefore Xg of NaCl will dissolve in 0.125L of the solution i.e

Xg of NaCl = 292.25 x 0.125 = 36.53g.

Therefore 36.53g of NaCl will dissolve in 125mL of the solution

Answer:

1. a = 2, b = 1 and c = 2

2. a = 1, b = 3, c = 2 and d = 2

Explanation:

According to law of conservation of mass, the mass can neither be created nor destroyed.

Hence, for a chemical equation the left hand side should be equal to the right hand side.

Therefore, the two balanced equations are;

2 CO + O₂ → 2 CO₂

C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O

Porque esta vivo un ser vivo?
Illusion [34]

Answer:

<u></u>

  • <u>Scientifically speaking, living things are alive because they have complex systems that allow them to be born, grow, reproduce and, when systems fail, die.</u>

Explanation:

The translation of the question is:

  • why is a living being alive?

<h2>Solution</h2>

Answering from a scientific point of view, not a philoshophical one, a <em>living </em>organism is differentiated from a non-living entity in that the <em>living being</em> is born, grows, has the ability to reproduce and dies.

All that is possible because the living beings posses a complex network of systems that sustain their life.

Those systems include the homeosthasis, the metabolism, the answer to external stimulus, the ability of adaptation, the development (growing) and the reproduction.

To be considered a living being the organism must count wiht all those systems.

It is important that you know that viruses are not living organisms: they are chemical molecules which do not have metabolism and do not grow.
