Answer:
The answer to your question is 1.2 moles of copper
Explanation:
Data
mass of copper = 75 g
moles = ?
Process
1.- Look in the periodic table for the atomic mass of copper.
Atomic mass = 63.55 g/mol
2.- Use proportions to determine the moles of copper in 75 g
63.55 g of copper -------------------- 1 mol
75 g of copper -------------------- x
Use cross multiplication
x = (75 x 1) / 63.55
x = 75 / 63.55
x = 1.18 moles ≈ 1.2 moles of copper
A bimolecular reaction can be kinetically first order in behaviour provided one of the reactants is taken in such a large excess that its concentration may hardly change. Such a reactant will not contribute to the order. Thus, a bimolecular reaction will be of first order. These reactions are known as pseudo chemical reactions.
Answer:
The products will be;
CO₂ + H₂O + NaC₂H₃O₂
Explanation:
We are given;
Two reactants NaHCO₃ and HC₂H₃O₂
We are supposed to determine the products;
- We need to know that hydrogen carbonates reacts with acids to give water, carbon dioxide and a salt as the products.
Therefore;
- In this case, sodium hydrogen carbonates (baking soda) reacts with acetic acid to form water, carbon dioxide and sodium acetate.
- The equation for the reaction is;
NaHCO₃ + HC₂H₃O₂ → CO₂ + H₂O + NaC₂H₃O₂
- Therefore, the products of the complete reaction between sodium hydrogen carbonate and acetic acid are CO₂ + H₂O + NaC₂H₃O₂
The solute normally doesn't dissolve and sinks to the bottom of the container. However, some saturated solutions can become super-saturated for a given temperature and pressure, by altering the conditions without allowing solute to precipitate.
Gases have three characteristic properties: (1) they are easy to compress<span>, (2) they expand to </span>fill<span> their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal</span>combustion engine<span> provides a good example of the ease with which gases can be compressed.</span>
