Cl2O5+H20-->2HClO3
Just remember to have the same number of each element on both sides of the equation.

Radium is used to produce Radon
Explanation:
Radon is a gas used to treat cancer (certain types).
Answer:
MgSo4 is the right answer
Answer:
3120.75J
Explanation:
So, we have the formula 
. For this example, q is the heat energy in Joules, m is the mass in grams, c is the specific heat capacity in 
, and 
t is the change in temperature. In this case, m = 47.5g, c = 0.9 , and t = 94-21 = 73°C. Plugging in the values, we get the joules of heat required to raise 47.5g of Al from 21°C to 94°C which is stated above. You can double check my answer but that should be it. An important thing to be aware of are the units. Sometimes, the heat capacity may not be . I may be in Kelvin or something. Anyways, hope this helps.
Answer:
A) Cations
Explanation:
a) Cations have a positive charge and are larger than their neutral counterparts!
b) Anions have a negative charge and are smaller than their neutral counterparts
c) Metals can have either a positive or negative charge making it either a cation or an anion
d) Carbon is an element and it can have a charge anywhere from +4 to -4
A good way to remember that cations are positive is to think that CATions are always PAWSitive! ^-^
