Answer:
The answer to your question is the letter A. 1
Explanation:
Data
Chemical reaction
(NH₄)₂CO₃ ⇒ NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 1
1 Carbon 1
8 Hydrogen 5
3 Oxygen 3
This reaction is unbalanced
(NH₄)₂CO₃ ⇒ 2NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 2
1 Carbon 1
8 Hydrogen 8
3 Oxygen 3
Now, the reaction is balanced,
The coefficient for Carbon dioxide is 1
Answer = C. As the temperature increases, the speed of gas molecules increases.
As the temperature increases, the gas molecules gain kinetic energy, therefore their speed increases.
<h3>Answer:</h3>
Cyclopentane (C5H10)
<h3>Explanation:</h3>
The molar mass of CH2 is about 14.3, Since empirical is a ratio just divide the given molar mass by the molar mass of the empirical. 70.15/14.3=5 So now multiple everything by 5 in the empirical equation.
So, a compound that has an empirical formula of CH2 and a molar mass of 70.15 will have molecular formula of" C5H10".
It is both a and b
nuclear rxns will ALWAYS have changes in both mass and some of that mass will be converted into energy.
