4 0

CH4O(I) + O2(g) = CO2(g) + H2O(g) 2 CH4O(I) + 3 O2(g) = 2 CO2(g) + 4 H2O(g) it is the double reaction. CH4O(I): Molar mass is 32.0419 g/mol C - Carbon; H - Hydrogen; O - Oxygen O2(g): Molar mass is 31.99880 Â± 0.00060 g/mol O - Oxygen CO2(g): Molar mass is 44.0095 g/mol C - Carbon: O - Oxygen H2O (g): Molar mass is 18.01528 Â± 0.00044 g/mol H - Hydrogen; O - Oxygen

The incomplete table below shows selected characteristics of gas laws.

Elenna [48]

Explanation :

In the given case different law related to gas is given. The attached figure shows the required solution.

Boyle's law states that the pressure is inversely proportional to the volume of the gas i.e.

$P\propto \dfrac{1}{V}$

$PV=k$

k is a constant.

Charle's law states that the volume of directly proportional to the temperature of the gas.

$V\propto T$

$V=kT$

Combined gas law is the combination of the pressure, volume and the temperature of the gas i.e.

$\dfrac{PV}{T}=k$

Hence, this is the required solution.

why does every human measurement have uncertainty associated with it? Why must we manage the uncertainty during calculations?

dimulka [17.4K]

Because there are many numbers of the human measurement . we must manage the uncertainly doing calculations because we can know what we are calculating.

A species has the following MO configuration: (σ1s)2(σ1s*)2(σ2s)2(σ2s*)2(σ2p)2(π2p)2. This substance is:_______.

Goshia [24]

Answer : The correct option is, (a) paramagnetic with two unpaired electrons.

Explanation :

According to the molecular orbital theory, the general molecular orbital configuration will be,

$(\sigma_{1s}),(\sigma_{1s}^*),(\sigma_{2s}),(\sigma_{2s}^*),(\sigma_{2p_z}),[(\pi_{2p_x})=(\pi_{2p_y})],[(\pi_{2p_x}^*)=(\pi_{2p_y}^*)],(\sigma_{2p_z}^*)$

As there are 14 electrons present in the given configuration.

The molecular orbital configuration of molecule will be,

$(\sigma_{1s})^2,(\sigma_{1s}^*)^2,(\sigma_{2s})^2,(\sigma_{2s}^*)^2,(\sigma_{2p_z})^2,[(\pi_{2p_x})^1=(\pi_{2p_y})^1],[(\pi_{2p_x}^*)^0=(\pi_{2p_y}^*)^0],(\sigma_{2p_z}^*)^0$

The number of unpaired electron in the given configuration is, 2. So, this is paramagnetic. That means, more the number of unpaired electrons, more paramagnetic.

Hence, the correct option is, (a) paramagnetic with two unpaired electrons.

A block of aluminum weighing 140 g is cooled from 98.4°C to 62.2°C with the release of 1080 joules of heat. From this data, calc

GrogVix [38]

Answer:

Specific heat of a substance is the value that describe how the added heat energy of substance has the impact on its temperature.

Unit is $(\frac {J}{Kg.K})$

C = Q/m. ∆T

C – Specific heat $(\frac {J}{Kg.K})$ 

Q- heat energy (J)

M – Mass (Kg)

∆T- change in temperature (K) 

Explanation:

Given data:

M= 140 g = 0.14 Kg

Q – 1080 Joules.

∆T – 98.4 – 62.2 = 36.2

Substituting the given data in Equation

Specific heat of Aluminium = $\frac {1080}{(0.14 \times 36.2)} = 213.10 (\frac {J}{Kg.K})$
