Answer:
P₂ = 1.37
Explanation:
Given data:
Initial pressure = 1.15 atm
Initial temperature = 23°C (23+273= 296 K)
Final pressure = ?
Final temperature = 79°C (79+273=352 K)
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.15 atm / 296 K = P₂/352 K
P₂ = 1.15 atm × 352 K / 296 K
P₂ = 404.8 atm. K /296 K
P₂ = 1.37 atm
Answer:
the answer will be lithium bromide + sodium
Explanation:
because displace sodium from bromine there by liberating sodium as an element in the product side
I believe that the answer for this question would be option A. 8 HOURS. Based on the given scenario above about a certain radioactive isotope placed near a Geiger counter, the half-life <span>of the isotope 32 hours later would be 8 hours. Hope this is the answer that you are looking for. </span>
Answer:
If both fluorine atoms are combine than each atom have 8 valance electrons and total valance electrons in both atoms are 16.
Explanation:
Fluorine is halogen atom. The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements.
There seven valance electrons in each halogen atom. They need one electron to complete the octet.
Fluorine atom combine with its another atom through covalent bond and share its one of valance electron with other atom thus both have 8 valance electrons and total valance electrons in both atoms are 16.
