To convert the formula unit to mass, we need to divide the given formula units by Avogadro's number, 6.022 x 10^23 and we get the mole of beryllium nitrate. To convert to mass, we need to multiply the number of moles with the molecular formula of the compound which is 133.022 g/mol.The answer is 0.006185 g or 6.185 mg.
Answer:
See explanation
Explanation:
Given that the formula of the compound is Fe2O3, if a coefficient of 2 is placed in front of the formula, that is, if we write 2Fe2O3 . Then;
The number of Fe atoms becomes 2 *2 = 4
The number of oxygen atoms becomes 2*3 = 6
That is why the total number of iron atoms were written down as 4.
Answer:
producer to decomposer
Explanation:
This is because in a food chain , energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun. Energy flow directly from the producer to the primary consumer which are heterotrophs that feed on plants. Energy flow from consumer to decomposer after the consumer died and it is decayed.
Explanation:
Equation of reaction:
CO + 2H₂ ⇒ CH₃OH + energy
a. An increase in pressure:
A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.
An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa
CO + 2H₂ ⇒ CH₃OH + energy
3 moles 1 moles
An increase in pressure will favor the forward reaction to be favored.
b. Addition of H₂:
An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.
Addition of hydrogen gas increases the concentration of amount of substances reacting.
To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.
