What is the name of the collection of elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence?
s-block elements
d-block elements
f-block elements
p-block elements
l-block elements

p-block elements

Explanation:

The periodic table is a display of known chemical elements arranged from left to right as well as top to bottom in the order of increasing atomic number. A total of 118 elements are known till date.

These elements are grouped into 4 different 'blocks'

s-block includes there first two groups on the left of the periodic table- the alkali (group 1) and alkaline earth metals (group 2. Here the s-orbitals get filled up sequentially

p-block includes groups 13-18 except helium. These elements are present on the right side of the periodic table with electrons sequentially filling up the p-orbitals

d-block includes groups 3-12, known as the transition metal series. These elements are present in the center of the periodic table with electrons sequentially filling up the d-orbitals

f-block includes the lanthanide and actinide series also known as inner transition metals. These elements are present in the bottom of the periodic table with electrons sequentially filling up the f-orbitals

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
