<u>Out of all given options, Hubble's findings supported the big bang theory are as follows: </u>

  • The universe formed from a central point.
  • Most galaxies in the universe are moving away from Earth.
  • There are billions of galaxies in the universe, not just one.

Option C, D, and E

<u>Explanation: </u>

According to big bang theory, the universe is increasing its region of occupancy in free space. As it is known that the universe is composed of several galaxies. So this spreading of the universe is nothing but spreading of galaxies.

And this is confirmed from Hubble’s findings using Hubble’s telescope.  As they have observed that the speed at which the galaxies are travelling in free space has been increased at a faster rate.

So, the galaxies are used to move away from Earth with time at a faster rate which confirms the big bang theory of universe formation. Also, in simple words, universe started from big bang according to cosmology' standard theory, it’s just moves from everything else.

It is likely the neutral atom has 6 protons and 6 electrons; while the negatively charged atom has 7 or more electrons.

The mass of an atom, commonly known as the atomic mass is determined by the number of protons and neutrons as electrons have a very low mass.

This means two atoms can have the same number of protons and neutrons, but a different number of electrons, which would make the atom be charged negatively or positively.

Based on this, if there are two atoms, each with 6 protons but one of these is negatively charged it is because the second atom has 1 or more extra.

Neutral atom:

  • This atom has 6 protons and an unknown number of neutrons located in the nucleus.
  • This atom has 6 electrons that orbit the nucleus.
  • The first energetic level will include 2 electrons while the second energetic level will include the 4 remaining electrons.

Negatively-charged atom:

  • This atom has 6 protons and an unknown number of neutrons located in the nucleus.
  • This atom has 7 or even more electrons that orbit the nucleus.
  • The first energetic level will include 2 electrons while the second energetic level will include up to 8 electrons.

What determines the temperature of an object at the molecular level?
Temka [501]
At the molecular level, temperature is related to the random<span> motions of the particles (</span>atoms<span> and molecules) in </span>matter<span>. Because there are different types of </span>motion, the particles' kinetic energy (energy of motion) can take different forms, and each form contributes to the total kinetic energy of the particles.<span>

A sample of an unknown compound contains 82.63% C, and 17.37% H. Determine the empirical formula.
Leno4ka [110]

The actual amount of substance doesn’t matter for this problem, so assume an easy mass of compound using the percentages: 82.63 g C and 17.37 g H. There is also no need to worry about significant figures in an empirical formula problem.

Find the number of moles of each element:

(82.63 \text{ g C})(\frac{1 \text{ mol C}}{12.011 \text{ g C}} )=6.88 \text{ mol C}\\(17.37 \text{ g H})(\frac{1 \text{ mol H}}{1.0078 \text{ g H}} )=17.2 \text{ mol H}

Find the ratio of the elements, and simplify until there are whole numbers that you can put into the empirical formula.

\frac{17.2 \text{ mol H}}{6.88 \text{ mol C}} =\frac{2.5 \text{ mol H}}{1 \text{ mol C}}=\frac{5 \text{ mol H}}{2 \text{ mol C}}

There are 5 mol H for every 2 mol C, so the empirical formula should be {\text{C}}_2{\text{H}}_5.
