Answer:

Mainly It would start out on Jupiter, Then Saturn, Uranus, and finally Neptune. Maybe even the orginal planet that got ejected out of the solar system by Jupiter, Planet 9.

Explanation:

Mainly they are gas giants just because of their distance from the sun and the materials that they picked up at the dawn of the Solar system 3.3 billion years ago.

Orbits and sizes are not shown to scale. A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.

An isotope contains 56 protons, 54 electrons, and 74 neutrons. What is the identity of the isotope? Choose 1 answer:
Dovator [93]

Answer:

Barium.

Explanation:

Each chemical element is characterized by the number of protons in its nucleus, which is called the atomic number Z. But in the nucleus of each element it is also possible to find neutrons, whose number can vary. The atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.

The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element. Isotopes means "same place", that is, since all the isotopes of an element have the same atomic number, they occupy the same place in the Periodic Table. So if a neutron is added to an atom, it becomes an isotope of that chemical element.

The isotopes of an element have the same chemical properties, but differ somewhat in their physical properties.

Barium has an atomic number of 56 (number of protons). Also, the mass number of this barium isotope is 130 (56 protons + 76 neutrons). Finally, since it has 54 electrons, two negatively charged electrons less than the number of positively charged protons, this isotope is a cation with oxidation number +2.

Vaselesa [24]
<h2>A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical energy. nuclear energy.</h2><h2>ans: electromagnetic energy, thermal energy, solar energy, and mechanical energy.</h2>

Explanation:

Wind mill

It consist of shaft pole and blades that can rotate .

It converts wind energy into electrical energy .

The shaft of wind mill is connected to shaft of armature of generator .

When the fast moving wind rotates the blades of windmill its shaft rotates, armature rotates hence electricity is produced which is further used for various purposes .  

Advantage of using wing energy

it is natural renewable resource  

It is eco friendly  

Disadvantage :

1. It cant be established everywhere  

2. It requires large area  

3. It is an expensive project  

4. Wind dosen't blow all the time so win energy cant be produced every time  

5. Minimum speed of wind required is 15km per hour .

So, the wind turbine generating electricity involves mechanical energy of wing and blades .

Using the equation below, calculate the number of grams of CO that can react completely with 78.9 g Fe2O3
yulyashka [42]

Answer:

                       41.51 g of CO

Explanation:

                      The balance chemical equation for given double displacement reaction is,

                                     Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

Step 1: <u>Calculate moles of Fe₂O₃:</u>

Moles = Mass / M.Mass

Moles = 78.9 g / 159.68 g/mol

Moles = 0.494 moles

Step 2: <u>Calculate moles of CO:</u>

According to equation,

                   1 mole of Fe₂O₃ reacted with  =  3 moles of CO

so,

                 0.494 moles of Fe₂O₃ will react with  =  X moles of CO

Solving for X,

                      X  =  0.494 mol × 3 mol ÷ 1 mol

                      X =  1.482 moles of CO

Step 3: <u>Calculate Mass of CO as:</u>

Mass = Moles × M.Mass

Mass = 1.482 mol × 28.01 g/mol

Mass = 41.51 g of CO
