PPRR, PpRR, PPRr, and PpRr
Answer: 78.54 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
According to stoichiometry :
2 moles of 
react with 1 mole of 
0.98 moles of react with =
moles of
Mass of 
Thus 78.54 g of are required to react completely with 29.5 g of NO.
I believe the first one is correct
Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
It is group 16. That is, Chalcogens. They call it the oxygen family.
