Question

theory question is there can you give answer to me ​

Answer 1

Answer:

K2SO4(aq) + Ba(NO3)2(aq) →BaSO4(s) + 2 KNO3(aq)? This equation represents a double displacement (replacement) reaction, also called a metathesis reaction, in which the reactant ions exchange places to form new products.

Answer 2

$1) k_{2}so_{4} + ba(no_{3})_{2} = baso_{4} + kno_{3}$

$k_{2}so_{4} + ba(no_{3})_{2} = baso_{4} +( k_{2}no_{3})_{2}$

$The \: Equation \: is \: balanced \: \\ by \: K \: and \: 2$

$2) \: \: h_{2}o_{3} + h_{2}o = al(oh)_{3} + h_{2}$

$This \: Equation \: is \: Balanced$
