Which is the missing value that will balance the equation?
0-1
0 0
0 +1
O +2

+1

Explanation:

Let x be the missing value in the equation as shown below:

²²₁₁Na —> ²²₁₀Ne + ⁰ₓβ

The missing value (x) can be obtained as follow:

11 = 10 + x

Collect like terms

11 – 10 = x

1 = x

x = 1

Therefore, the missing value (x) is +1 and the balanced equation is:

²²₁₁Na —> ²²₁₀Ne + ⁰₁β

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
