There are 2 different types of atoms there, that's why
Answer:12 seconds
Explanation:the formula is s=d/t.
s= speed, d=distance, and t= time
Solve for t
Your new arranged formula is t=d/s
T=108/9
T= 12
Dii ok not forget your units
Answer:
Explanation:
To neutralize a chemical to a pH of 7 before discarding, one would require a significant amount of acids or bases. Our best guess is that the solution in itself is either an acid or a base. Neutralization with the right amount of a proper reagent can bring the pH of the solution to a neutral 7.
If the solution has a pH originally greater than 7, add a corresponding amount of acid to it. This will reduce the concentration and bring it to a neutral point. Provided one is dealing with a solution of pH less than 7, simply add a base to to bring the solution to neutrality.
I believe the answer is two
Molar Mass of 1 molecule of methane(CH4) = 12 + 4 = 16g/mol
That is, 16g if CH4 contain 1 mole molecule of it
= 6.022×10²³ molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.
=> 4 g of CH4 contains 1/4 × 6.022×10²³ molecules
= 1.5055×10²³ molecules of CH4
= 1.5055×10²³ C atoms and 6.022×10²³ H atoms
Note: the question should be how many atoms of hydrogen and carbon and not molecules.
Hope it helps…
