Answer:

B.  4 Fe + 3 0₂---> 2 Fe₂O3        

Explanation:

(A) Ir + O₂--> IrO₂                                 No:  Ir is iridium

(B) 4 Fe + 3 0₂---> 2 Fe₂O3                Yes:  Fe is iron and O is oxygen,                  and the equation is balanced.

(C) I+ 0₂ ---> 10₂                                  No:  I is iodine

(D) 3 Ir + 0₂ -> 6 Ir₂03                         No:  I is iodine

You wish to make 250. mL of 0.20 M KCl from a stock solution of 1.5 M KCl and DI water.
Nitella [24]

The question requires us to use the dilution formula M_iV_i=M_fV_f, where M_i and V_i are the stock concentration and volume respectively, then M_f and V_f are the dilute concentration and volume respectively.

a. C_s_t_o_c_k= 1.5 M KCI, C_d_i_l_u_t_e=0.20M KCl, V_d_i_l_u_t_e=250ml KCl

b.M_iV_i=M_fV_f\\\implies V_i= \frac{M_fV_f}{M_i} = \frac{0.20M \times 250ml}{1.5M} = 33.3\ ml

To prepare the solution 33.3ml of 1.5M KCl is diluted to a total final volume of 250ml.
