4.2 At 1 atm pressure, ice melts at 273.15 K. In addition, !:,J/ fus = 6.009 kJ/mol, density of ice = 0.92 g/cm3, and density of liquid water = 1.00 g/cm 3 • (a) What is the melting point of ice under 50 atm pressure? . (b) The blade of an ice skate is ground to a knife edge on each side of the Problems 117 ~kate. ! ~e :~d= ~f the knife edge is 0.001 in., and the length of the skate m con c WI e Ice is 3 in., calculate the pressure exerted on the ice by a 150 lb man. (Assume that the skater u . d ) . . ses one e ge. (c) What IS the melting point of ice under this pressure?

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
