Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
Where, the molar mass of each element are:
Calculating the molar mass of the compound, we have:
Now, calculating what is the mass of 6.78 of , we have:
So, there are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
Have a nice day!
Answer:
Yes
Explanation:
Thermal radiation is emitted by any surface having a temperature higher than absolute zero. So the short answer to your question is yes. Light (electromagnetic radiation) of any frequency will heat surfaces that absorb it.
I hope it helps.
Synthesis, decomposition, single replacement and double replacement.
Synthesis- two or more reactants unite to form a single product
S (Sulfur) + O2 (Oxygen) ——> SO2 (Sulphur dioxide)
Decomposition- A single reactant is decomposed or broken down into two or more
CaCO3 (Calcium Carbonate) ——> CaO (Calcium oxide) + CO2 (Carbon dioxide)
Single replacement- A single free element replaces or is substituted for one of the elements in a compound. The free element is more reactive than the one its replaces.
Zn (Zinc) + 2 HCI (hydrochloric acid) ——> H2 (hydrogen) + ZnCl2 (Zinc Chloride)
Double replacement- This reaction type can be viewed as an "exchange of partners." For ionic compounds, the positive ion in the first compound combines with the negative ion in the second compound, and the positive ion in the second compound combines with the negative ion in the first compound.
HCI (hydrochloric acid) + NaOH (sodium hydroxide) ——> NaCl (Sodium Chloride) + HOH (water)
Once reactants have absorbed enough heat energy from their surroundings to reach the transition state, the reaction will proceed. The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.

Ptolemy was an astronomer and mathematician. He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory.
