Covalent bonds is your answer, have a good one.
Answer:
1. A
2. D
3. E
4. B
5. C
Explanation:
1. Plants are known as producers since they produce energy for themselves through photosynthesis.
2. The rabbit is a primary consumer since it’s herbivore and only feeds on producers for energy.
3. The tiger is a carnivore, and preys on other consumers for energy.
4. A human is an omnivore since it can gain energy from both producers and consumers.
5. Bacteria are know as decomposers since such category of organisms break down other organisms to gain energy.
<span>*the ratio of moles of solute to liters of solution </span>
From the periodic table:
mass of oxygen = 16 grams
mass of carbon = 12 grams
mass of iron = 55.84 grams
Therefore:
molar mass of Fe3O4 = 3(55.84) + 4(16) = 231.52 grams
number of moles = mass/molar mass
number of moles of Fe3O4 = 23 / 231.52 = 0.099 moles
The balanced chemical equation that describes this reaction is:
<span>Fe3O4 + 2C --------> 2CO2 + 3Fe
From the balanced reaction above, we can note that:
one mole of Fe3O4 requires two moles of carbon to react with.
Therefore, to know the number of carbon moles required to react with 0.099 moles of Fe3O4, all you have to do is cross multiplication as follows:
number of carbon moles = (2*0.099) / 1 = 0.198 moles

PLEASE MARK BRAINLIEST!</u></h2>
Answer:
Yes; mayonnaise is a liquid.
Explanation:
This is because, when you smear it on a slice of bread, it moves freely. Like ketchup, when you put it on your plate. Is ketchup a liquid? Yes, it is. So yes, mayonnaise is most definitely a liquid.
