Answer:

The characteristic of silicon that is most closely related to its chemical reactivity is that;

It is found in nature in mainly as oxides and silicates

Explanation:

Silicon, which is a member of group 14 of the periodic table has the electron configuration of [Ne]3s²3p² and has a high affinity for oxygen such that the the oxides are known as silicates and it is almost impossible to find pure silicon in nature and it is found in the universe as silica and silicates

Silicate minerals make up over 90% of the Earth's crust such that, by mass silicon is only surpassed by oxygen as the most abundant element found in the Earth's crust.

Answer:

The answer to your question is 0.005

Explanation:

Data

Volume of NaOH = 25 ml

[NaOH] = 0.2 M

moles of NaOH = ?

To solve this problem is not necessary to have the chemical reaction. Just use the formula of Molarity and solve it for moles.

Formula

Molarity = moles / volume

-Solve for moles

moles = Molarity x volume

-Convert volume to liters

          1000 ml ---------------- 1 l

              25 ml ---------------- x

               x = (25 x 1) / 1000

               x = 0.025 l

-Substitution

moles = 0.2 x 0.025

-Result

moles = 0.005

Can someone help with this please?
Aleks04 [339]
I think the answer would be yes. if my math is correct 84,596 divided by 29 equals 2,917 sickles. 2,917 sickles is equal to 172 galleon. therefore he would have enough to buy the 70 galleon broomstick. hopefully i did this right and it helped!
