iron Bars form a solenoid when wrapped in a coil by a current carrying copper conducting wire .
copper coils generate a magnetic field when a current is passed through the coil . according to the helmholtz law.
0.0760 m
do this by:
finding the moles of NaOH which will be <span>5.702 E -3 m
</span>
next find the moles of H3PO4 which will be <span>1.90 E -3 m</span><span>
calulcate </span>25 ml sample molarity = 0.07603 m, just put 0.0760<span>
</span>
Answer:
3.01×10²³ atoms of calcium
Explanation:
number of moles = number of atoms/Avogadro's constant
n = N/NA
N = n×NA = 0.500 mol×6.02×10²³ mol^-1
N = 3.01×10²³ atoms of calcium
Answer:
118
Explanation:
The discovery of the 118 chemical element known to exist us of 2021
And the answer is False,it does not have the same number with particles as the one mole of hydrogen.
