Answer:
Ionic solid.
Explanation:
Ionic solid dissociated into free ions capable of conducting electricity in aqueous solution. Ionic solids are also characterised by high melting point due to strong ionic bonds. No free ions or electrons to conduct electricity in solid form.
Before you can identify how much you need, first you need to
solve and write the equation.
You need to know first that you need to convert grams of ZnO --> moles of ZnO
= 358.5 g ZnO x 1 mol ZnO / 81.39g ZnO
Solve and it will give you = 4.40 mol of ZnO
Next, multiply the answer above to 1 mol O2 / 2 mol ZnO
It will give you the answer of 2.20 mol of O2
Multiply the answer above to the molar mass. This will give
you the answer of what you’re looking for.
Molar mass: 32
= 2.20 mol O2 x 32g O2 / 1 mol O2
= 70.4g O2
The grams of O2 that are required to produce 385.5 grams of
zno is: 70.4 g O2
Answer:
The water cycle is driven primarily by the energy from the sun.
ANSWER; resultant.
When vectors are added or subtracted, the net force is called the RESULTANT
