Answer: The number of molecules of gas the flask contains is
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 2.50 L
n = number of moles = ?
R = gas constant =
T =temperature = 273K (STP)
According to Avogadro's law:
1 mole of gas at STP contains = molecules
Thus 0.112moles of gas at STP contains = molecules
The number of molecules of gas the flask contains is
Answer:
Total of all numbers added with the correct rounding and number of significant figures
Explanation:
1. Add up all the numbers
8.32+8.00+8.30+8.3
2. Determine how many significant figures should be in your final answer. When it comes to addition, it will be the fewest number of decimal places. since 8.3 has one decimal place, your final answer should only have one decimal place.
3. Round your final answer to the nearest tenths

Answer:
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Explanation:
The principle of writing balanced chemical reaction equations states that; the number of atoms of each element on the right hand side of the reaction equation must be equal to the number of atoms of the same element on the left hand side of the reaction equation.
The reaction is between aqueous aluminum phosphate reacts and solid magnesium to produce solid aluminum and aqueous magnesium phosphate. The equation is represented as follows;
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
