O
Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
In your case, the balanced chemical equation for this synthesis reaction looks like this
2
H
2(g]
+
O
2(g]
→

Notice that the reaction requires
2
moles of hydrogen gas and
1
mole of oxygen gas to produce
2
moles of water.
This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.
You know that your reaction uses
6.0
moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce
6.0

Explanation:
The lack of a spinal column is the distinguishing characteristic of invertebrates.
<h3>What is an Invertebrate?</h3>
These are organisms which lack a backbone(vertebral column) while vertebrates on the other hand have it.
This is why option C was chosen as the most appropriate choice in this scenario.

Answer:
The two samples have identical properties because they are the samples of the same element. Intensive properties are properties of matter that do not change depending on the amount of matter. Luster, reactivity, and ductility are all intensive properties. That is why the two samples can be different sizes or shapes, but have identical properties.
Answer:
2 electrons from magnesium (Mg) is transferred to oxygen (O2) to form Mg2+ and O2-
which combines by strong electrostatic force to form MgO
the equation is
2Mg + O2 -> 2MgO
