Protons and neutrons, just like in the nucleus of every other element.
Answer:
f = 0.6× 10¹⁶ Hz
Explanation:
Given data:
Wavelength of radiation = 5.00 × 10⁻⁸ m
Frequency of radiation = ?
Solution:
Formula:
Speed of light = wavelength × frequency
speed of light = 3 × 10⁸m/s
Now we will put he values in formula.
3 × 10⁸m/s = 5.00 × 10⁻⁸ m × f
f = 3 × 10⁸m/s / 5.00 × 10⁻⁸ m
f = 0.6× 10¹⁶ s⁻¹
s⁻¹ = Hz
f = 0.6× 10¹⁶ Hz
Answer:
Concentration, pressure, and temperature are the three factors that affect chemical equilibrium
Answer:
We need 12.26 grams H2SO4
Explanation:
Step 1: Data given
Volume of a H2SO4 solution = 500 mL = 0.500 L
Concentration of the H2SO4 solution = 0.250 M
Molar mass of H2SO4 = 98.08 g/mol
Step 2: Calculate moles H2SO4
Moles H2SO4 = concentration * volume
Moles H2SO4 = 0.250 M * 0.500 L
Moles H2SO4 = 0.125 moles
Step 3: Calculate mass of H2SO4
Mass of H2SO4 = moles * molar mass
Mass of H2SO4 = 0.125 moles * 98.08 g/mol
Mass of H2SO4 = 12.26 grams
We need 12.26 grams H2SO4
The answer should be D, cells can only create an identical copy of the original cell.
