Answer:

The answer to your question is the letter d) 16700 joules

Explanation:

Data

mass = m = 86.8 g

temperature 1 = T1 = 40°C

temperature 2 = T2 = 86°C

heat capacity = 4.18 J/g°C

Process

1.- Write the formula to calculate Heat (Q)

        Q = mC(T1 - T2)

2.- Substitution

        Q = (86.8)(4.18)(86 - 40)

3.- Simplification

        Q = (86.8)(4.18)(46)

4.- Result

         Q = 16689.9 Joules ≈ 16700 joules

Fill in the blanks: Electrons are ___ in an ionic bond, whereas they are___ in a polar covalent bond, and ___ in a nonpolar cova
NNADVOKAT [17]

Answer:

The correct answer is "transferred; unequally shared; equally shared".

Explanation:

Ionic bonding occurs when a positively charged atom (cation) interacts with a negatively charged atom (anion). In ionic bonding, the cation transfers its electron to the anion. In polar covalent bonding, electrons are unequally shared. This means that the electrons spend more time in an atom than the other, which gives partial positive and negative charges to the atoms. On the other hand in nonpolar covalent bonding, the electrons are equally shared and no charges are created.

When nitrogen gas reacts with hydrogen gas, ammonia gas is formed. how many grams of hydrogen gas are required to react complete
aniked [119]
The balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ ---> 2NH₃
stoichiometry of N₂ to H₂ is 1:3
we need to find the moles of N₂, volume of N₂ has been given 
molar volume is where 1 mol of any gas occupies a volume of 22.4 L at STP.
if 22.4 L is occupied by 1 mol 
then 3.5 L of gas is occupied by - 3.5 L / 22.4 L/mol = 0.16 mol 
number of moles of N₂ present - 0.16 mol
1 mol of N₂ requires 3 mol of H₂
therefore 0.16 mol of N₂ requires - 3 x 0.16 = 0.48 mol of H₂
mass of H₂ required - 0.48 mol x 2 g/mol = 0.96 g
0.96 g of H₂ is required
