Answer:

1 O₂

Explanation:

In the combustion reaction of hydrogen, oxygen combines with hydrogen to form water as the product of the reaction

Equation of reaction:

2H₂ + O₂ → 2H₂O

From the equation of reaction, it is evident that 2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles of water.

Therefore the coefficient of oxygen in the equation is 1.

What is the correct defination for carbon tetrachloride
V125BC [204]

B - CCL4

This is because it doesn't say Dicarbon or any of that sort, so Carbon is alone. This immediately eiminates the option of C.

A is incorrect as it has Chlorine first rather than Carbon, so that's also incorrect.

D is incorrect as 7 is hepta rather than tetra.

The list is as so;

Mono - 1; Di - 2; Tri - 3; Tetra - 4; Penta - 5; Hexa - 6; Hepta - 7; Octa - 8; Nona - 9; Deca - 10.

Hope this helps!

What is the role of an indicator in an acid-base titration? In your answer, identify how an appropriate indicator is chosen and
Anton [14]
An indicator shows where the endpoint of a titration is.  Different indicators will change colors at different equivalence points.  Phenolphthalein will change colors at around pH7.5 or so, and others like Methylene Blue will change around a pH of 6.  Different titrations will have different pH's at different equivalence points.
