I believe an atom. may be wrong, science is not my strong suit
Answer:
Calcium bromide
Explanation:
When naming compounds, the use of prefixes depend on the type of bond made. In this case, calcium and bromine form a ionic bond because calcium is a metal and bromine is a non-metal.
Ionic bonds are not named using prefixes. So no matter how many atoms there are, you will simply write the name of the element for the first element.
For the second element, you name it as well, but only use the root name and end it with -ide.
Sodium hydroxide and bleach have several characteristics in common and that includes: both can conduct electricity in solution, both can be found in the cleaning products and they are able to produce hydroxide ions in solution. However, their pH are not less than 7. Sodium hydroxide has a pH of 13, while bleach has a pH of 11. Therefore, both of them has a pH greater than 7. So the characteristic that they don't have in common is letter A.
Answer:
The new volume of the gas is 4.74L
Explanation:
Data;
T1 = 14°C = (14 + 273.15)K = 287.15K
V1 = 4.5L
T2 = 29°C = (29 + 273.15)K = 302.15
V2 = ?
From Charles law,
The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT
k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.
V1 / T1 = V2 / T2
Solving for V2
V2 = (V1 * T2) / T1
V2 = (4.5 * 302.15) / 287.15
V2 = 4.735L
V2 = 4.74L
The new volume of the gas is 4.74L
