In the following reaction, what element is made?
2 answers:
Answer: The correct answer is option (A).
Explanation:
General representation of an element:
A= Atomic mass of the element of X.
Z = Atomic number of the element of X
X = symbol of the element.
According to Law of Conservation of Mass:
A = 244
Charge is balanced on both the sides:
Z = 97
The element with the atomic number 97 is Berkelium. Hence, the correct answer is option (A).

The volume in liters of 3245 aluminum cans is 24.8 L.
A recycling center collects 3245 aluminum cans and there are 22 aluminum cans in 1 lb. The mass of 3245 aluminum cans is:
To convert mass to volume, we need the density of aluminum (5.95 lb/L). The volume corresponding to 147.5 lb of aluminum is:

Answer:
Final volume is 3.50L
Explanation:
It is possible to find volume of a gas using combined gas law:
<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>
If initial state of the gas is:
1.75L of a gas is at 700K and is under 250kPa of pressure
And final state is:
298K and 53.2kPa.
Replacing:
0.625L = 0.1785*V₂
<em>3.50L = V₂</em>
Thus, <em>final volume is 3.50L</em>
