Answer:
a. the 3 represents the principal energy level
Explanation:
3 is the principal energy level. The p is the sublevel. 4 is the possible occupying electron.
Answer:
V = 34.55 L
Explanation:
Given that,
No of moles, n = 1.4
Temperature, T = 20°C = 20 + 273 = 293 K
Pressure, P = 0.974 atm
We need to find the volume of the gas. It can be calculated using Ideal gas equation which is :
PV=nRT
R is gas constant, 
Finding for V,
So, the volume of the gas is 34.55 L.
M(H2SO4)=n*M=4.75*98=465.5g
Answer:
HCl
Explanation:
Given data:
Mass of Zn = 50 g
Mass of HCl = 50 g
Limiting reactant = ?
Solution:
Chemical equation:
Zn + 2HCl → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = mass / molar mass
Number of moles = 50 g/ 65.38 g/mol
Number of moles = 0.76 mol
Number of moles of HCl:
Number of moles = mass / molar mass
Number of moles = 50 g/ 36.5 g/mol
Number of moles = 1.4 mol
Now we will compare the moles of Reactant with product.
Zn : ZnCl₂
1 : 1
0.76 : 0.76
Zn : H₂
1 : 1
0.76 : 0.76
HCl : ZnCl₂
2 : 1
1.4 : 1/2×1.4 = 0.7
HCl : H₂
2 : 1
1.4 : 1/2×1.4 = 0.7
Less number of moles of product are formed by HCl it will act limiting reactant.
Lets go over what our properties are
-Mass is a measure of the amount of matter available.
<span>
-Density is the ratio of mass to volume. Density is determined to be a physical object</span>
<span>-Volume is the amount of space occupied by the object. </span>
<span>-Solubility is the amount of a substance required to form a saturated solution with a specific amount of solvent at a specified temperature.
</span>
-Mass is the same size and weight of an object for the most part which cannot be the same for a bigger or smaller object. Which means density cannot either since density has a direct correlation with mass. Volume is usually the size occupied at the current time. This means it cannot be the same for a large and small object. Note that! Then we have solubility which is the amount required or needed but since you are just crushing the solid it would wind up still being the same amount.
-With this all put together we can say your answer is probably Solubility and Desnity.
