Q = 5637 J
C =4.814 J/KgºC
Temperature : 45.5ºC - 20.9º C = 24.6ºC
Q = m x C x T
5637 = m x 4.814 x 24.6
5637 = m x 118.4244
m = 5637 / 118.4244
m = 47.60 g
hope this helps!
In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.
Answer:
the answer is H ..............
Answer:
the answer is : true ice and snow melts into water in sublimation
Answer:
18
Explanation:
The atomic number of chlorine is 17 therefore the atom has 17 electrons, the ion however has 1 extra electron. The charge becomes negative because electrons have a negative charge. 17 + 1 = 18, therefore a chlorine ion with a charge of -1 has 18 electrons.
