8_murik_8 [283]

Answer:

0.87708moldm-3

Explanation:

molar \: mass \: of \: cuso4 = 63.55 + 32.07 + 4(16.00) \\  =159.62gmol {}^{ - 1}   \\ mole(n) =  \frac{mass}{molar \: mass }  \\ n =  \frac{35}{159.62}  \\ n = 0.21927mol \\ molarity =  \frac{n}{v}  \\ molarity =  \frac{0.21927}{0.25} \\ molarity = 0.87708moldm {}^{ - 3}

What must be conserved in a balanced nuclear equation?
Law Incorporation [45]
There is nothing conserved<span> in this reaction. When writing a β </span>equation<span>, remember that in the nucleus, a neutron ( n ) decays into a proton ( p+ ) and a high energy electron which is known as the beta ( β ) particle. Because a new proton has formed, the atomic number of the original atom will increase by 1</span>

Aleksandr-060686 [28]
 The  formula  equation for  the reaction  between  hydroiodic  acid  and  beryllium  hydroxide      is as below

Be(OH)2  +  2 HI   =  BeI2 +   2H2O


Formula  of  hydroiodic is  =  HI
formula   of  beryllium hydroxide = Be(OH)2


1 mole  of  Be(OH)2  react  with   2  mole  of HI to form  1 mole  of BeI2  and   2   mole  of H2O
