In a polyatomic ion, the ate ending indicates one more oxygen than the ite ending. D. more.
Answer:
Mg is oxidized and Pb is the oxidizing agent
Explanation:
Answer: C. The number of collisions of gas particles decreases
Explanation: As temperature decreases so does everything else same with increase.
Molarity is expressed as:
Molarity = moles / liter
Given that the cell is rod-shaped, its volume is calculated using the formula for a cylinder's volume:
V = πr²L
V = π * (0.6)² * 4.9
V = 5.54 μm³
1 Liter = 10³ mm³
1 mm = 10³ μm
1 mm³ = 10⁹ μm³
1 liter = 10¹² μm³
So the volume in liters is:
5.54 x 10⁻¹² L
Moles = molarity * liters
Moles = 0.0029 * 5.54 x 10⁻¹²
Moles = 1.61 x 10⁻¹⁴
To get the number of molecules, we multiply the moles by Avagadro's number
Number of molecules = 1.61 x 10⁻¹⁴ * 6.02 x 10²³
There are 9.69 x 10⁹ molecules in the cell
6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.
