Answer:
0.895 g/mL
Explanation:
Step 1: Given data
Mass of liquid Z (m): 2.763 lb
Volume of liquid Z (V): 5.93 cups
Step 2: Convert "m" to grams
We will use the relationship 1 lb = 453.59 g.
![2.763 lb \times \frac{453.59 g}{1lb} = 1,253g](https://tex.z-dn.net/?f=2.763%20lb%20%5Ctimes%20%5Cfrac%7B453.59%20g%7D%7B1lb%7D%20%3D%201%2C253g)
Step 3: Convert "V" to milliliters
We will use the relationship 1 cup = 236.59 mL.
![5.93cup \times \frac{236.59mL}{1cup} = 1.40 \times 10^{3} mL](https://tex.z-dn.net/?f=5.93cup%20%5Ctimes%20%5Cfrac%7B236.59mL%7D%7B1cup%7D%20%3D%201.40%20%5Ctimes%2010%5E%7B3%7D%20mL)
Step 4: Calculate the density of the liquid Z
The density (ρ) of the liquid Z is equal to its mass divided by its volume.
![\rho = \frac{m}{V} = \frac{1,253g}{1.40 \times 10^{3}mL } = 0.895 g/mL](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D%20%3D%20%5Cfrac%7B1%2C253g%7D%7B1.40%20%5Ctimes%2010%5E%7B3%7DmL%20%20%7D%20%3D%200.895%20g%2FmL)
Answer:
coloumbs
Explanation:
the value of the charge on a proton is Coloumbs
Answer:
The coefficient for Al(s) is 2.
Explanation:
__ Al(s) __ O2(g) --> __ Al2O3(s)
__ Al(s) __ O2(g) --> 1 Al2O3(s)
1 Al(s) __ O2(g) --> 1 Al2O3(s)
1 Al(s) + 1.5 O2(g) --> 1 Al2O3(s) [Use a fraction to make it balance]
2 Al(s) + 3 O2(g) --> 2 Al2O3(s) [Convert the 1.5 fraction to a whole number by multiplying all coefficients by 2]
Answer:
The Bohr Model is very limited in terms of size. Poor spectral predictions are obtained when larger atoms are in question. It cannot predict the relative intensities of spectral lines. It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field.

Answer:
![^{32}_{15}P](https://tex.z-dn.net/?f=%5E%7B32%7D_%7B15%7DP)
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
However, when we talk about the atomic number of the ion, it is not equal to the number of electrons as electron can be gained or loosed.
This is why, more appropriately, the number of the protons which are present in the nucleus of the atom is called the atomic number.
Thus, atomic number of phosphorus = 15
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Given, Mass number = 32
Thus, the symbol of the isotope is:-
