Answer from: itssmookie6540

The chemical formula of a compound formed between aluminium and chlorine atom will be AlCl_3

Explanation:

Aluminium is the 13th element of the periodic table with electronic configuration of 1s^22s^22p^63s^23p^1

As, this element will easily loose 3 electrons and hence will show an oxidation state of +3.

Chlorine is the 17th element of the periodic table with electronic configuration 1s^22s^22p^63s^23p^5

This element will easily gain 1 electron and shows an oxidation state of -1.

By criss-cross method, the oxidation state of aluminium and chlorine gets exchanged and thus they form the coefficients of the compound.

The compound formed by the combination of aluminium and chlorine will be AlCl_3

Hence, the chemical formula for the compound will be AlCl_3

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.

Answer from: Quest

answer: e. sour taste

explanation: acids are those substances which dissociates in water to give $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

$hcl\rightarrow h^++cl^-$

bases are those substances which dissociates in water to give $oh^-$ ions or accepts $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

$naoh\rightarrow na^++oh^-$

$nh_3+h^+\rightarrow nh_4^+$
