Answer:
Be^2+
Explanation:
The atomic number indicates the number of protons so the element is Be (beryllium)
So now we know that a neutral atom contains four electrons but there are 2 so that means two electrons were taken away, making it positive. It would be a 2+ charge.
The density will not change. Unless you change the mass as well, the volume changing will not change the density
<span>To
solve this we assume that the gas is an ideal gas. Then, we can use the ideal
gas equation which is expressed as PV = nRT. At number of moles the value of PV/T is equal to some constant. At another
set of condition of temperature, the constant is still the same. Calculations
are as follows:</span>
P1V1/T1 = P2V2/T2
P1 = P2V2T1/T2V1
P1 = (114)(1.32)(596)/(715)(.654)
P1 = 191.80 kPa
The phenotype for the genotype bb would be Purple and white
Answer:
The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
