when balancing a chemical equation, which of the following is/are permissible? choose one or more: removing elements from a formula placing a coefficient in front of a formula adding or removing a substance changing a subscript in a formula part 2 (1 point) xef6 is a strong fluorinating agent. it hydrolyzes in water to produce xeo3, according to the unbalanced equation below: xef6(l) + h2o(l) → xeo3(s) + hf(g) which elements are currently not balanced? choose one or more: o f h xe

Answer

Explanation:

Step1: Recall balancing rules

When balancing a chemical equation, we can only change the coefficients in front of formulas. Changing sub - scripts, removing elements from a formula, or adding/removing substances is not allowed as it would change the identity of the substances involved. So for the first part, placing a coefficient in front of a formula is permissible.

Step2: Analyze element counts in the given equation

In the equation $XeF_{6}(l)+H_{2}O(l)\rightarrow XeO_{3}(s)+HF(g)$, for Xe, there is 1 Xe on both sides. For F, there are 6 F on the left - hand side and 1 F on the right - hand side. For H, there are 2 H on the left - hand side and 1 H on the right - hand side. For O, there is 1 O on the left - hand side and 3 O on the right - hand side. So F, H, and O are not balanced.

Answer:

Part 1: B. placing a coefficient in front of a formula Part 2: A. O B. F C. H
