Answer:
625=275
240=x
625x=275×240
625x=66000
x=66000/625
x=105 .6
Explanation:
If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625
Answer:
Explanation:
Hello there!
In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:
We are to calculate the specific heat of the ethanol as shown below:
Thus, by plugging it the given data we can obtain:
Regards!
Answer:
A
Explanation:
Remember the number of valence electrons represent the group number. As shown in figure, there is only one electron in the valence shell. Therefore, this element belongs to group 1 elements also called as Alkali metals.
Furthermore, the number of electrons in a neutral atom equals number of protons. Hence, there are 11 protons in this element.
Also, number of protons equal atomic number therefore, the atomic number of this element is 11. And, by checking periodic table, the element having atomic number 11 is Sodium (Na).
