Answer:
Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2
Explanation:
1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios. This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction
2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.
3. A reaction with more reactants will need more care because more products are produced, which can be toxic
4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound
Answer:
The answer to your question is 6
Explanation:
Data
Cu + 2AgNO₃ ⇒
To find the answer, count the number of each element in the reactants
Element Quantity
Copper 1
Silver 2
Nitrogen 1
Oxygen 6
Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
Answer:- An empirical formula of adrenaline is 
.
Solution:- Convert given percentages to moles and then calculate the mol ratio to get the simplest whole number ratio of moles of atoms which is the empirical formula of the compound.
= 4.725 mol
= 6.56 mol
= 1.773 mol
= 0.591 mol
let's calculate the mol ratio now. To calculate the mole ratio, we divide the moles of each by moleso f N as it's the least one:
= 8
= 11
= 3
= 1
So, an empirical formula of adrenaline is .
