Answer:
A
Explanation:
bc inorganic compoud refers to all compound that do not contain carbons.
If we have two gram produce 2 grams were consumed
Due to the mass conversation law which state that the mass in a isolated is neither created nor destroyed by chemical reaction or physical transformation. Therefore the mass of the product must be equal to the mass reactant
Answer:
All are correct
Explanation:
This might be a little deceptive. The question shows H, O and N which would designate ELEMENTS.
However, all of these can also be considered compounds and molecules as well. BUT, they are H₂, O₂ and N₂ when they are molecules and compounds.
So it depends on the whether the question is being literal or not.
Use the 1st order decay equation
<span><span>Cfinal</span>=<span>Cinitial</span><span>e<span>−kt</span></span></span>
by filling in and doing the math you will get:
<span> </span><span>Cfinal</span><span> = 1.11 grams Rn-222 after 23 days.
hope this helps

Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in
the products
Explanation:
For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass
