According to Law of conservation of matter," matter can neither be created nor destroyed but is conserved and remains constant over time'.
In above picture let suppose the Blue balls represent N₂ molecule and White balls represent H₂ molecules.
So, left picture represent reactants,
2 N₂ + 6 H₂
And , right picture represent products,
4 NH₃
So, there are 4 N atoms and 12 Hydrogen atoms in reactants and 4 N atom and 12 Hydrogen atoms in products. Means the mass of elements is conserved. The overall reactions is as follow,
2 N₂ + 6 H₂ → 4 NH₃
Result:
Yes! This reaction follow Law of conservation of Matter.
Answer:
I don't even know tbh but maybe we could be friends
Answer:
H2CO3 = 2H+ + CO3-
Explanation:
It is simply what carbonic acid breaks down into when placed in water. Since carbonic acid is made up of H and CO3, these are the products.
Answer:
1.2 × 10^22 atoms.
Explanation:
Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.
Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mole = mass/molar mass
Mole = 1.17/58.5
Mole = 0.02moles
Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.
In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+
0.1204 × 10^23 atoms
1.2 × 10^22 atoms of Na+ (cation)
