When a solution of beryllium sulfate and calcium hydroxide are mixed, what precipitate if any is formed
klasskru [66]

Answer:

CaSO₄ (calcium suflate) is the precipitate formed

Explanation:

We can think the reactants:

BeSO₄ → Beryllium sulfate

Ca(OH)₂ → Calcium hydroxide

The reaction is:

Be₂SO₄  +  Ca(OH)₂  →  CaSO₄ ↓  +  Be(OH)₂

We call it as a double-replacement reaction because two ions exchange places from 2 compounds to form two new compounds.

Sulfates can always make precipitate with the elements from group 2, Ca, Ba and Mg.  

Hydroxides from group 2 are solubles, so we complete states:

BeSO₄ (aq)  +  Ca(OH)₂ (aq)  →  CaSO₄ ↓ (s)  +  Be(OH)₂ (aq)

COMPLETE<br> How many grams of CaCl2 are in 250 mL of 2.0 M CaCl2?
saul85 [17]

Answer:

There are 55, 49 g of CaCl2

Explanation:

We calculate the weight of 1 mol of CaCl2:

Weight CaCl2=Weight Ca + 2x(Weight Cl)= 40,08g+ 2x 35, 45g=110,98 g/mol

1000ml-----2 mol of CaCl2

250ml------x= (250 ml x 2 mol of CaCl2)/1000ml= 0,5 mol of CaCl2

1mol -----110,98g

0,5mol ---x= (0,5molx110,98g)/1 mol= <em>55,49 g</em>
