Answer: Option (d) is the correct answer.
Explanation:
Since the given formula is 
. According to cross method formula, magnesium has +2 charge so, 
is multiplied by 2.
Thus, 1 molecule of magnesium phosphate will contain 2 atoms of phosphorus.
Therefore, three molecules of magnesium phosphate contains following number of atoms.
Hence, we can conclude that there are 6 atoms of phosphorus in three molecules of magnesium phosphate, .
Answer:
The answer to your question is V = 0.108 L or 108 ml
Explanation:
Data
Volume = ?
mass = 0.405 g
Temperature = 273°K
Pressure = 1 atm
Process
1.- Convert mass of Kr to moles
83.8 g of Kr -------------------- 1 mol
0.405 g ------------------- x
x = (0.405 x 1) / 83.8
x = 0.0048 moles
2.- Use the Ideal gas law to solve this problem
PV = nRT
- Solve for V
V = nRT / P
- Substitution
V = (0.0048)(0.082)(273) / 1
- Simplification
V = 0.108 / 1
- Result
V = 0.108 L
2) carbon and hydrogen only.
Answer:
1. The balanced equation is given below:
C4H6O3 + H2O → 2C2H4O2
The coefficients are: 1, 1, 2
Explanation:
C4H6O3 + H2O → C2H4O2
The above equation can be balanced as follow:
There are 4 atoms of C on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of C2H4 O2 as shown below:
C4H6O3 + H2O → 2C2H4O2
Now, the equation is balanced as the number of atoms of the different elements present on both sides of the equation are equal.
The coefficients are: 1, 1, 2
