Answer:
1. Mg(CH3CO2)2 - magnesium acetate
2. NH4CN - ammonium cyanide
3. NaClO3 - sodium chlorate
Answer:
Because looking at the reactivity series of both elements Calcium is more reactive than hydrogen.
by applying the equation :
n = N/L
where
n = mol
N = number of molecules
L = avagardro constant
therefore :
N = n × L
= 9.95mol × 6.022 ×10²³ mol-¹
= 59.9189
(this has no units)
Answer is: yes, <span>atomic emission spectra of cobalt be the same on Earth as on the moon.
</span>Differente gravity or no atmosphere on Moon don't affect emission spectra of elements,
Emission spectrum<span> of a </span>chemical element<span> is the spectrum of frequencies </span><span>emitted due to an </span>atom <span>making a </span>transition from a high energy state to a lower energy state. <span>Each element's emission spectrum is unique.</span>
