in the equation 2kclo3 → 2kcl + 3o2, how many moles of oxygen are produced when 3.98 mol of kclo3 decompose completely?

Answers

Answer 1

Answer: 2 KClO₃= 2 KCl + 3 O₂

2 moles KClO₃ -------> 3 moles O₂
3.98 moles KClO₃ -----> ?

moles O₂ = 3.98 x 3 / 2

moles O₂ = 11.94 / 2

= 5.97 moles of O₂

hope this helps!

The solution set of axequalsb is the set of all vectors of the form wequalspplusbold v subscript h, where bold v subscript h is any solution of the equation axequals0.

Answers

Answer : Incorrect

Explanation : In the given solution set of Ax = b;
is set of all vectors to form w= p + $V_(h)$
here $V_(h)$ is is any solution of the equation Ax = 0;

this stands to be incorrect, as the correct would only exists when some vector p is found to be like this Ap=b

What can the arrow in a chemical reaction be translated to mean?

Which statement regarding serum magnesium (Mg ++) is true? (Select all that apply.) Alcohol-related diseases frequently cause low Mg+ levels. Vomiting is not generally seen as a major cause of Mg+ loss. Mg++ levels present similarly to calcium (Ca++) levels in the blood. Mg+ deficiencies often result in low serum potassium (K+) levels. Mg+ deficiencies must be treated before potassium (K+) deficiencies.
