Answer:
2Ag + H2O -----> Ag2O + 2H
Explanation:
2Ag + H2O -----> Ag2O + 2H is the equation of the reaction between metal and steam. Silver reacts with water (steam) forming silver oxide and hydrogen gas. When the metals react with steam it produces the solid metal oxide and hydrogen gas. On the surface o metals, a protective layer of aluminium oxide is formed that keeps water away from the metal so we can say that silver oxide and hydrogen are formed from the reaction of silver metal and steam.
Answer:
See answer below
Explanation:
The picture below will show you the final product and mechanism.
In the first step, the NaNH₂ is a strong base, so, this base will substract the hydrogen from carbon 2, to generate a negative charge there, and then, carbon 2 becomes a nucleophyle.
As a nucleophyle it will attack to the CH₃I in the next step, and it will attach to the CH₃.
The second step is just a regular step to reduce the triple bond of the alkyne to alkane or alkene, this will depend on the quantity of the reactant. In this case, an alkene.

<h3>Answer:</h3>
3.7 Moles of Nitrogen
<h3>
Explanation:</h3>
On observing the chemical formula C₈H₁₁NO₂ (might be formula of Dopamine) it is found that one mole of this compound contains;
8 Moles of Carbon
11 Moles of hydrogen
1 Mole of Nitrogen and
2 Moles of Oxygen respectively.
<u>Calculate Number of Moles of Nitrogen:</u>
As,
1 Mole of C₈H₁₁NO₂ contains = 1 Mole of Nitrogen
So,
3.7 Moles of C₈H₁₁NO₂ will contain = X Moles of Nitrogen
Solving for X,
X = (3.7 Moles × 1 Mole) ÷ 1 Mole
X = 3.7 Moles of Nitrogen
The answer is d you are welcome
4.002602 u
Being one of the lightest elements in the world, Helium has an atomic mass of 4.0026 u. u means Unified Atomic Mass Units. 1 u equals to the mass of 1/12 of the mass of a 12C ( Carbon - 12 ) isotope.
