Answer:
The correct answer is a. chemical bond. See the explanation below, please.
Explanation:
The resulting electrostatic interaction is called ionic bond between ions of opposite charge (one negative and one positive). This allows the attraction between both charges, constituting a chemical compound. Eg the Sodium (Na +) ion combines with the Chlorine (Cl-) ion forming Nacl (sodium chloride, known as table salt).
The energy required to heat 40g of water from -7 c to 108 c is
1541000 joules
calculation
Q(heat)= M( mass) x c(specific heat capacity) xdelta t( change in temperature)
M= 40g= 40/1000= 0.04 Kg
C= 335,000 j/kg/c
delta T ( 108 --7= 115 c)
Q is therefore = 0.04 g x 335000 j/kg/c x 115 c = 1541,000 joules
Answer:
96.1 grams of percent yield
Did you mean NaCl + F2 = NaF + Cl2 ? Balanced equation: ... Units: molar mass - g/mol, weight - g
The number of protons is equal to the atomic number of every element in the periodic table.
Example: The atomic number of Niobium (Nb) is 41. Therefore, the number of protons is also 41.
