Answer:

Explanation:

%mass of glucose =( mass of gucose /mass of solution )x100%

= 163 / (755+ 163 )

= 17.76 %

Balance the following reaction and use the equation to calculate the ΔHrxn. C3H8(g) + O2(g) → CO2(g) + H2O(g) Round your answer

gladu [14]

The reaction corresponds to the combustion of propane (C3H8). The balanced reaction is:

C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

The reaction enthalpy is given as:

ΔHrxn = ∑nΔH°f(products) - ∑ nΔH°f(reactants)

= [3ΔH°f(CO2(g)) + 4ΔH°f(H2O(g)] - [1ΔH°f(C3H8(g)) + 5ΔH°f(O2(g)]

= [3(-393.5) + 4(-241.8)] - [-103.9 + 5(0)] = -2043.8 kJ

The enthalpy for the combustion of propane is -2044 kJ

How many electrons are present in an uncharged atom with its 1s, 2s, 2p, 3s, 3p and 4s subshells filled and with five electrons

marshall27 [118]

25

Explanation

The orbital quantum number of an atomic subshell determines the maximum number of electrons it can contain. For example:

Each $s$ orbital $(l = 0)$ holds up to $4 \; l + 2 = 2$ electrons
Each $p$ orbital $(l = 1)$ holds up to $4 \; l + 2 = 6$ electrons
Each $d$ orbital $(l = 2)$ holds up to $4 \; l + 2 = 10$ electrons

The atom in question here contains four fully-occupied $s$ orbitals, two fully-occupied $p$ orbitals along with $5$ electrons in a partially-occupied $d$ orbital. It thus contains

$4 \times 2 + 2 \times 6 + 5 = 25 \; \text{electrons}$

A runner wants to run 10.4 km k m . She knows that her running pace is 8.0 mi/h m i / h .

mars1129 [50]

Answer:

Approximately 49 minutes.

Explanation:

1 mile = 1.6 km

So 8.0 x 1.6 km

Minutes required: $\frac{10.4 times 60 }{8.0 times 1.6}$ = 48.75 minutes

I hope this helped :)
