Blance equation __CaBr2 (aq) + ___Li3PO4(aq) → ___Ca3(PO4)2(s) + ____LiBr (aq)
QveST [7]

Answer:

3CaBr2 + 2LI3PO4 - > Ca3(PO4) 2 + 6LiBr

Explanation:

The first one I did was PO4. There are two on the right side, so I added 2 to Li3PO4 on the other side. That balanced the PO4s and then gave me 6 Lithiums so I balanced that one next on the right side. I added 6 to LiBr which balanced the Li but then gave me 6 Br, so I finished it off by adding 3 in front of CaBr2 which balanced the calcium and bromines.

Here was the process:

CaBr2+2Li3PO4 -> Ca3(PO4)2+LiBr

Balances PO4 (2on both sides)

CaBr2+2Li3PO4 -> Ca3(PO4)2+6LiBr

Balances Lithiums (6 on each side)

3CaBr2+2Li3PO4 -> Ca3(PO4)2+6LiBr

Balances Calciums and Bromines (3 Calciums and 6 Bromines each side)

Hope this helped!

Describe 3 everyday situations in which it would be useful to identify unknown substances and explain how you would identify the
andrew-mc [135]

The three situations can be described as

a) If we have two white powders and wish to distinguish between the two : the combinations can be sugar / salt or sugar / baking soda or salt / baking soda

all are kitchen items so we can either taste them

or in case of baking soda we can add it in water and it will produce brisk effervescence.

b) IF we have to distinguish in a given set of two transparent liquids which appear to be water (example water and vinegar)

we can identify them with the taste

we can identify them based on pH (vinegar will be acidic)

c) We have to find adulteration in a given sample of food

like adulteration in milk

for example presence of soap in milk

We can add indicator like phenolphthalein which will bring a pink colour in milk if soap is present

deff fn [24]
You can tell that a crystal is a crystal if it creates a rainbow prism effect. Or you can tell by tapping the crystal. If he crystal makes a musical ring noise (like how a glass cup would sound) it’s a crystal.
