Hey there!

B + O₂ → B₂O₃

Balance O.

2 on the left, 3 on the right. Add a coefficient of 3 in front of O₂ and a coefficient of 2 in front of B₂O₃.

B + 3O₂ → 2B₂O₃

Balance B.

1 on the left, 4 on the right. Add a coefficient of 4 in front of B.

4B + 3O₂ → 2B₂O₃

Our final balanced equation: 4B + 3O₂ → 2B₂O₃

Hope this helps!

The radioisotope that has the longest half-life is the best to use in powering planet and space exploration vehicles because the
Diano4ka-milaya [45]

Answer:

U-238

Explanation:

For a given radioisotope, half life can be defined as the time taken for the isotope to decay into one-half of its original amount. Mathematically, this is expressed as:

t_{1/2} = \frac{0.693}{k}

where k = rate constant for the radioactive decay process

Greater the t1/2 longer will be its stability.

Based on the given data, U-238 has the largest half life and therefore will be best suited for applications mentioned.

Consider the chemical equation below.
igor_vitrenko [27]

Answer : The net ionic equation will be,

2H^{+}(aq)+2OH^-(aq)\rightarrow H_2O(l)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

Mg(OH)_2(aq)+2HNO_3(aq)\rightarrow Mg(NO_3)_2(aq)+H_2O(l)

The ionic equation in separated aqueous solution will be,

Mg^{2+}(aq)+2OH^-(aq)+2H^{+}(aq)+2NO_3^{-}(aq)\rightarrow H_2O(l)+Mg^{2+}(aq)+2NO_3^{-}(aq)

In this equation, Mg^{2+}\text{ and }NO_3^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

2H^{+}(aq)+2OH^-(aq)\rightarrow H_2O(l)
