Answer:
Explanation:
Hello!
In this case, since we can see that the heat released by the combustion of the mayonnaise is absorbed by the bomb calorimeter and water, we can set up the following equation:
Whereas q for mayonnaise stands for the heat due to its usage; thus, we plug in to obtain:
Now, if 10.0 g are eaten, the energy provided by it turns out:
And we need that value in dietary calories, 1 kcal:
Best regards!
Silver is Ag from the latin Argentum
Lead is Pb from the latin Plumbum
Answer:
Because they lack chlorophyll (a green pigment in plants that helps them trap sunlight, used to manufacture their food through photosynthesis)
Explanation:
Mushrooms are heterotrophs. They are not plants or autotrophs. Mushrooms, just like every living thing that exists need energy in order to live. Only plants, or autotrophs, can directly use energy from the sun (the ultimate energy) to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs. Mushrooms are fungi (belong to kingdom Fungi) and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesis due to lack of chlorophyll.
In chemistry, "chemical properties" of elements usually refers to the electron affinity of an atom (number of valence electrons) This is because atoms with the same number of valence electrons will form similar compounds with other atoms, and undergo the same types of reactions.
Out of this list: He, Ne and Ar are all group 18 elements (Noble gases)
Therefore they have similar chemical properties.
