Answer:
0.245 moles
Explanation:
moles of lithium = 2*moles of Li2SO4
so moles of LI2SO4=2.94*10^23/(2*6*10^23)=0.245
Answer: 2-Benzyloxyethanol is produced reaction in the fig. below.
Explanation:
Answer:
The answer to your question is:
Explanation:
e) 9.10 x 10³ + 2.2 x 10⁶ = 2.2091 x 10⁶
f) 1113.0 - 14.6 x 10² = -347 = -3.47 x 10²
g) 6.18 x 10⁻⁴⁵ + 4.72 x 10⁻⁴⁴ = 5.338 x 10⁻⁴⁴
h) 4.25 x 10⁻³ - 1.6 x 10⁻² = -0.01175 = -1.175 x 10 ⁻²
5.- Calculate ...
a) 2.63 x 10⁻⁴
b) 2.26 x 10¹³
c) 1.97 x 10²
d) 1.65 x 10⁻²³
e) 2.5 x 10⁻⁸³
f) 1.61 x 10¹⁴
g) 2 x 10⁷⁹
h) 2.37 x 10⁻⁷
°C + 273.15 = K. The basic formula for converting Fahrenheit into Celsius is (°F − 32) × 5/9 = °C. To convert Fahrenheit degrees into Kelvins, (°F − 32) × 5/9 + 273.15 = K.
Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Isotopes have the same number of protons and having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
number of atoms = 11
mass number = 23
number of neutrons=23-11=12
number of atoms = 11
mass number = 24
number of neutrons=24-11=13
