Answer:

yes.

Explanation:

If you have a liquid and you want to know if it is acidic, an easy way to tell is to mix in a little baking soda. The baking soda reacts with acids to produce bubbles.

You may be familiar with building a homemade kitchen volcano. You mix vinegar (an acid) with baking soda. It foams up as the baking soda reacts with the acid. This is in essence what you can do to test if a solution is acidic or not. If there is no acid present, the solution will not bubble when you add the baking soda.

What is the formula of a compound in which element y form ccp lattice and atom x occupy 1/3rd of tetrahedral voids

Kisachek [45]

Y : CCP : 4 atoms
X : tetrahedral voids would be 1/3 × 8 = 8/3

so formula would be Y12X8 or Y3X2 !!

how many ml of a 22.5% (v/v) ethanol solution would you need to measure out in order to have 12.5 ml of ethanol ?

Aleks [24]

Volume percent or volume/volume percent (v/v%) is used when preparing solutions of liquids. It will have units of volume of the smaller composition substance over the volume of the solution. We calculate as follows:

12.5 mL ethanol = .225 mL ethanol / 1 mL solution ( V )
V = 55.56 mL of the 22.5 % by volume ethanol solution is needed

Hope this answers the question.

The partial negative charge at one end of a water molecule is attracted to the partial positive

Neporo4naja [7]

Answer:

Hydrogen Bond

Explanation:

Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.

In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.

Use the solubility rules to determine if:

xenn [34]

Answer:

A reaction is said to occur if there is a formation of an insoluble solid or a precipitate(s) or a liquid (l) or a gas(g).

If both the reactants and products are in aqueous state, No reaction takes place.

$2 \mathrm{NaCl}(a q)+M g B r_{2}(a q)>M g C l_{2}(a q)+2 \mathrm{NaBr}(a q)(\mathrm{NO} \text { REACTION })$

All chlorides and Bromides are soluble except that of Ag, Hg and Pb.

Hence, No reaction takes place since all the reactants and products are in aqueous states.

${KOH}(a q)+{NaCl}(a q)>K C l(a q)+{NaOH}(a q)(\mathrm{NO} \text { REACTION })$

Salts of Group IA are soluble. Hence No reaction takes place

$M g S(a q)+2 {NaOH}(a q)>M g(O H)_{2}(s)+N a_{2} S(a q)$

(REACTION TAKES PLACE)

All hydroxides are insoluble except that of Group IA, ammonium ion and Group IIA down from Calcium.

Hence Reaction takes place with the formation of $Mg(OH)_2$ precipitate
