Mass = moles x molar mass
molar mass of H2O is 18
therefore mass = 18 x 5
=90 g

Mass = Molar mass × No. of moles
Molar mass of Water(H2O) = 1+1+16 = 18 gm
No. of moles = 5
Therefore, total mass = 18 × 5 = 90 gm

How many joules are required to convert 16.5 g g of ice at 0.0 ∘C ∘ C to liquid water at 32.0 ∘C ∘ C ? The heat of fusion of wat
photoshop1234 [79]

Answer:

5511 J

Explanation:

Applying,

Q = Cm.................... Equation 1

Where Q = amount of heat required to convert ice, C = Heat of fusion of water, m = mass of ice

From the question,

Given: C = 334 J/g, m = 16.5 g

Substitute these values into equation 2

Q = 334(16.5)

Q = 5511 J

Hence, the amount of heat required is 5511 J

The combustion of ethane (C2H6)(C2H6) produces carbon dioxide and steam. 2C2H6(g)+7O2(g)⟶4CO2(g)+6H2O(g) 2C2H6(g)+7O2(g)⟶4CO2(g)
Vera_Pavlovna [14]

Answer:

11.9 moles of carbon-dioxide will produced.

Explanation:

Given moles of ethane = 5.95 mol

2C_2H_6(g)+7O_2(g)\rightarrow 4CO_2(g)+6H_2O(g)

According to reaction 2 moles of ethane produces 4 moles of carbon-dioxide.

Then, 5.95 moles of ethane will produce:

\frac{4}{2}\times 5.95 mol=11.9 mol of carbon-dioxide

11.9 moles of carbon-dioxide will produced.

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of xef2.
lys-0071 [83]

Answer: There are 4 bonding electrons and 18 non-bonding electrons.

Explanation: To determine the number of bonding and non-bonding electrons, we will use lewis dot structure for the molecule XeF_2

Lewis dot structure is the structure in which the valence electrons around an atom is shown in a molecule. It also tells us about the number of bonds present between the two neighboring atoms.

Valence electrons of Fluorine = 7

Valence electrons of Xenon = 8

In XeF_2

Total number of valence electrons  = [(1 × 8) + (2 × 7)] = 22 electrons

From, the structure attached below, the number of bonds present = 2. Hence, the bonding electrons will be = 4 electrons

  • Number of non - bonding electrons = Total valence electrons - Number of bonding electrons

Number of non-bonding electrons = 22 - 4 = 18
