Answer:
A. it is the lowest at low temperatures
Explanation:
It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.
The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.
- Kinetic energy is directly proportional to the temperature of a substance.
- The higher the temperature, the more the kinetic energy of the molecules within a system.
- At low temperature, kinetic energy is the lowest.
- At the highest temperature, kinetic energy is the highest
Answer:
The elements in the reactants are the same as the elements in the products.
Explanation:
You can't have more or less elements or atoms, but you also can't just have the same number of atoms because then it could be different elements, which can't happen.
sodium chloride
and lead (II) acetate
potassium sulfate and strontium iodide
chromium (III) nitrate and sodium phosphate
1.
2NaCl + Pb(CH3COO)2 → 2NaCH3COO + PbCl2
2.
K2SO4 + SrI2 → KI + SrSO4
3.
Cr(NO3)3 + Na3PO4 →CrPO4 + NaNO3
Answer:
"please please help me" LOL
Explanation:
Answer:
6.5256×10¹⁴
Explanation:
n= v/24
v= n×25
v= 2.719×10¹³ × 24= 6.5256×10¹⁴ moles/dm³
