Answer: 3.61 L
Explanation:
To calculate the moles, we use the equation:
2 moles of produce = 3 moles of
0.1 moles of produce = moles of
According to the ideal gas equation:'
P = Pressure of the gas = 1 atm (NTP)
V= Volume of the gas = ?
T= Temperature of the gas = 20°C = (20+273) K = 293 K (NTP)
R= Value of gas constant in in kilopascals = 0.0821 Latm/K mol
Thus volume of oxygen at NTP obtained by decomposing 12.26 g of is 3.61 L
Answer:
The answer is
<h2>0.35 g</h2>
Explanation:
The mass of a substance given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 0.253 mL
density = 1.38 g/mL
Substitute the values into the above formula and solve for the mass
We have
mass = 1.38 × 0.253 = 0.34914
We have the final answer as
<h3>0.35 g</h3>
Hope this helps you
Element: is a pure substance with one type of atom, and what makes an element unique is its atomic/proton number
isotopes: is two or more species of atoms of a chemical element with the same atomic/proton number.(meaning in I should job has the same element but different neutrons)
ions: is a atom that has lost or gained electrons
Hopefully i could help(this was all from my notes so it’s a bit more simplified!!
