The Empirical Formula is
<span>a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.</span>
The molarity of the acetic acid solution is calculated as below
calculate the moles of KOH used
moles =molarity x volume
= 20.9 x0.267 = 5.58 moles
write the reaction equation
KOH + CH3COOH = CH3COOK + H2O
since the reacting ratio between KOH to CH3COOH is 1:1 the moles of CH3COOH is also = 5.58 moles
molarity of CH3COOH = moles/volume
=5.58 /29.1 =0.192 M
Answer:
Around 129 galons
Explanation:
if you divied 3,241 by 4 you get 129 gallons but if you times that by 25 you get 3,225 so a little bit off but close.
The correct answer is option B, that is, an element.
A compound comprises of either more than one kind of atom or various similar atoms. They can be dissociated or can be converted into a simpler one. An element refers to a substance that comprises only one kind of atom. It cannot be dissociated further or can be converted into simpler substance by any chemical means.
Heterogeneous mixture refers to a non-uniform mixture of distinct atoms without any chemical bonding in between them. On the other hand, homogenous mixture refers to a uniform mixture of distinct atoms with the absence of any kind of chemical bonding in between them.
