Answer:
Carbon has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
Answer:
It results from microscopic bumps and ridges
It causes a change in motion
It is opposite to the direction of the motion.
It is parallel to the surfaces that rub together.
Explanation:
Here is your answer:
Your answer is A decreasing.
Reason: That's because when your turning into a solid your not moving and kinetic energy is the around of movement an object is moving.
Your answer is A.
Answer:
The answer is Graph A, because there is a direct relationship between pressure and volume.
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure.
Answer:
B. CaCl₂ + H₂CO₃ → CaCO₃ + 2HC
Explanation:
A balanced reaction has the same number of atoms in the both sides of the reaction. In the options:
A. CaCl₂ + H₂CO₃ → 2CaCO₃ + HCI
In this reaction there is 1 Ca in reactants and 2 in products -<em>The reaction is unbalanced-</em>
<em />
<h3>B. CaCl₂ + H₂CO₃ → CaCO₃ + 2HCl
</h3>
There is 1 Ca is both sides, 2Cl, 2H, 1C and 3 Oxygens -<em>The reaction is balanced</em>
<em></em>
C. CaCl₂ + 2H₂CO₃ → CaCO₃ + HCI
There is 1 Ca in both sides but 2Cl in reactants and 1 in Cl -<em>The reaction is unbalanced-</em>
<em />
D. 2CaCl₂ + H₂CO₃ →CaCO₃ + HCI
There are 2 Ca in reactants and 1 in Ca -<em>The reaction is unbalanced-</em>
