What is this element

Chemistry
1 answer:
ohaa [14]3 years ago
8 0

Answer:

Oxygen

Explanation:

From the question given above, the following data were obtained:

Number of electrons = 8

Number of protons = 8

Number of Neutrons = 8

Name of element =?

Next, we shall determine the atomic number of the element. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically, it is expressed as:

Atomic number = proton number

From the question given above,

Number of protons = 8

Therefore,

Atomic number = 8

Comparing the atomic number of the element (i.e 8) with those in the periodic table, we can conclude that the element is oxygen since no two elements have the same atomic number.

Which conversion factor do you use first to calculate the number of grams of CO2 produced by the reaction of 50.6 g of CH4 with
zlopas [31]

Answer:

This is the conversion factor, we have to use:

44 g / 1mol

Explanation:

The reaction for the methane combustion is:

CH₄ + 2O₂  →  CO₂  +  2H₂O

First of all we use this conversion factor to determine the moles of methane, we used.

50.6 g . 1 mol / 16 g = 3.16 mol

So ratio is 1:1, then 3.16 mol of methane will produce 3.16 moles of CO₂

To calculate the grams of produced dioxide:

3.16 mol . 44 g / 1mol = 139.04 g

Find w12, the work done on the gas as it expands from state 1 to state 2.
dem82 [27]
The equation for work is
W = PdV
and it is integrated and limits are the conditions of state 1 and state 2
If the gas is ideal and the expansion is isothermal, then P = nRT/V and the equation can be integrated with respect to V
If the process is adiabatic, the equation P1V1^g = PV^g can be used to substitue P in terms of conditions of State 1.
