It is found that after 24!hours 1/8 of the mass of a sample of a radio-active isotope remains What is the half-life of this isotope?
Answer:7.72 years
Nuclear half-life expresses the time required for half of a sample to undergo radioactive decay.
Explanation:
0.01 = 67.0 ×[tex](\frac{1}{2}) ^{\frac{98.0} {1/2 } }[/tex] [tex]\frac{0.01}{67.0}[/tex] = 0.000149=[tex](\frac{1}{2}) ^{\frac{98.0} {1/2 } }[/tex]
[tex]^{\frac{98.0} {1/2 } }[/tex] =log[tex]_{0.5}[/tex] (0.000149)=12.7
[tex]^{\frac{98.0} {1/2 } }[/tex]=7.72 years

Similarities and Differences in the order in which electrons are filled in s and d subshells.
Answer: Each orbital is found on different areas of the periodic table. The s sublevels are found on the first(left) and last(right) columns of the period table which hold a maximum of two electrons since it only has one orbital. First, each orbital can hold a maximum of two electrons. The other three sublevels: p, d, and f respectively have more orbitals, which is why they can hold more electrons. These sublevels of orbitals stand for sharp(s), principle(p), diffuse(d), and fundamental(f) (these are simply the categories of orbitals).
p has 3 orbitals so it can hold 6 electrons max. d has 5 orbitals so it can hold 10 electrons max. f has 7 orbitals so It can hold 14 electrons max.
Here is a picture of these orbital groups so you can understand a little better:
Which element has 5 protons 5 neutrons and 5 electrons
Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.
What are subatomic particles?Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.
The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.
Therefore, the element is boron.

height and finds the following:
| = 17 cm
w = 7.5 cm
h = 0.8 cm
What is the volume of Dashawn's phone?
Answer: Volume of rectangle = L * W * H
Explanation: Multiply the 3 numbers together
Answer:
volume = L x W x H
V= 17 x 7.5 x 0.8
V = 102 cm^3

This reaction shows that when ammonia react with oxygen it form water and nitrogen gas.
There are two reactants on left hand side oxygen and ammonia. Ammonia is formed when nitrogen and hydrogen react. While on right hand side there are two products nitrogen and water. Water is formed by the reaction of hydrogen and oxygen.
The given reaction also shows that it follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

When bonding, what is most likely to happen between the atoms listed below?
A.) Atom X will donate electrons to Atom Y
B.) Atom X will accept electrons from Atom Y
C.) Atom Y will accept electrons from Atom Z
D.) Atom Z will donate electrons to Atom X
Answer:
atom x will accept electrons from atom y
Explanation:
in bonding the main purpose is to gain stable electronic configuration hence atom y will give out the two valence electrons to atom x
this kind of bonding where one of the atom is the one donating the electrons is known as ionic bond.

1 mole of a gas occupies 22.4 L at ________
Answer: At STP, one mole (6.02 × 1023 representative particles) of any gas occupies a volume of 22.4 L (Figure below). A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm).
Explanation:
That the answer
1 mole of a gas occupies 22.4 L at (0°C and 1 atm). It is the standard temperature and pressure.
What is Avogadro's hypothesis?Avogadro's hypothesis says that all gases have an equal number of particles at the same temperature and pressure.
The empty space between the particles makes up the majority of a gas's overall volume.
Due to this, the size of the particles themselves is nearly insignificant.
The volume of one mole of a gas at standard temperature and pressure is known as the molar volume.
Thus, the correct option is 0°C and 1 atm.

Mass percentage does not have any unit as numerator and denominator contains the same unit. The percentage of sulfuric acid in solid sample is 38.07%.
What is percentage by mass?Mass percentage represents the the percentage of each element that is making a particular compound.
Mathematically,
Percentage of mass = (component’s mass ÷ total mass) x 100%
[tex]\rm 2 NaOH aq + H _{2} SO _{4} aq → Na _{2}SO _{4}aq + 2 H _{2} O[/tex]
Volume of NaOH solution = 32.22 mL = 0.03222 L
Concentration or molarity of the NaOH solution = 0.2012 M
Moles of NaOH : 0.03222×0.2012=0.006444mol
2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid.
0.006444mol of sodium hydroxide reacts with =0.006444÷2=0.003222mol of sulfuric acid.
Mass of sulfuric acid neutralized = 0.003222 moles × 98.08 g/mol =0.31601376g
Percentage of sulfuric acid in solid sample= (0.31601376g÷0.8390g)×100=38.07%
Thus the percentage of sulfuric acid in solid sample is 38.07%.
