It's <em>True</em> very true darling

USPshnik [31]3 years ago

True
Explanation:
It is very true that pollutants can be created both naturally and man-made this is because that all animals produce or intensionally cause pollution, and not only animals there are many non natural causes for pollution too some examples of this is volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres, an example of pollution that animals make is the methane and co2 produced after the digestion of foods in animals such as cows.Alyought humans are the leading cause of pollution with the increasing usage of plastic and the gas emmited from factories it is true that pollution can be caused by animals and by other non living causes.

Which contribution added to rutherfords discovery of a positive nucleus atoms are invisible electrons are scattered in an atom n
dedylja [7]

Answer:

neutrons are inside the nucleus

Explanation:

The most significant contribution that added to Rutherford's discovery of a positive nucleus is that neutrons are also inside the nucleus.

  • The discovery of neutrons as a nuclear particle was instrumental to Rutherford's discovery.
  • Since during his experiment, the alpha particles were deflected partly, he suggested a massive nucleus made up of just protons.
  • With the discovery of the neutron, the mass of the nucleus was enough to cause the deflection.

How many moles of Fluorine (F2) are<br><br> needed to completely react 8.0<br><br> moles of NF3?
Anna [14]

Answer:

12 moles of F₂

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

N₂ + 3F₂ —> 2NF₃

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e

Xmol of F₂ = (3 × 8)/2

Xmol of F₂ = 12 moles

Thus, 12 moles of F₂ is needed for the reaction.

How many moles of oxygen are in 1 mole of iron (II) nitrate?
Alekssandra [29.7K]

Answer:

Explanation:

One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:

1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3

3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen

9 moles of Oxygen in one mole Fe(NO3)3

3. Theoretically how many grams of magnesium is required to produce to 5.0 g of
FinnZ [79.3K]

Answer:

3grams

Explanation:

The reaction for the production of Magnesium dioxide will be

Mg + O2  → MgO

we have 5g of MgO (molar mass 40g)

no of moles of MgO = 5/40 = 0.125

Using unitary method we have

1 mole of Mg require 1 mole of MgO

0.125 Mole of MgO = 0.125mole of Mg

n = given mass /molar mass

0.125 = mass / molar mass

mass = 0.125* 24 = 3grams
