Taking into account the definition of density and Archimedes' principle, the beginner bowling ball will float on the water.
But first it is neccesary to know that density is a quantity referred to the amount of mass in a certain volume of a substance or a solid object.
In other words, the density is the relationship between the weight (mass) of a substance and the volume that the same substance occupies.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
In this case, a beginner's bowling ball has a mass of 4.9 kg and a volume of 5.4 liters. This is:
mass= 4.9 kg= 4900 g (being 1 kg= 1000 kg)volume= 5.4 L= 5400 mL (being 1L=1000 mL)Replacing in the definition of density:
[tex]density=\frac{4900 g}{5400 mL}[/tex]
Solving:
density=0.907 [tex]\frac{g}{mL}[/tex]
On the other hand, Archimedes' principle says that an object immersed in a liquid experiences an upward vertical force equal to the weight of the volume of the dislodged liquid.
The sinking or floating of an object is determined by its density with respect to that of the liquid in which it is submerged.
Considering water as the liquid where the object is submerged in this case, an object with a higher density than water will sink. In contrast, an object with a lower density than water will float.
In this case, considering that water has a density of 1 [tex]\frac{g}{mL}[/tex], the bowling ball for beginners has a lower density. This indicates that, having a lower density than water, the object will float.
In summary, the beginner bowling ball will float on the water.

How many cm of a solution of 0.100 mol dm NaOH are required to completely -3 neutralize 25.0 cm of 0.250 mol dm H3PO4?. a) Write a balanced equation for the reaction (4 marks) b) How many moles of H3PO4 need to be neutralized? (1 marks) c) How many moles of NaOH are needed to neutralize the H3PO4? (1 marks) d) How many cm of 0.100 mol dm NaOH contain the moles in question 5(©) above? (1 marks)
Answer:
Explanation:
How many cm of a solution of 0.100 mol dm NaOH are required to completely neutralize 25.0 cm of 0.250 mol dm H3PO4?.
a) Write a balanced equation for the reaction NaOH to neutralize (4 marks
?. ) 25.0 cm of 0.250 mol dm H3PO4
H3PO4 + 3NaOH----------> Na3PO4 +3 H2O
b) How many moles of H3PO4 need to be neutralized? (1 marks)
25.0 cm3 of 0.250 mol dm3 H3PO4: 1 liter has 0.25 moles. 100 ml has 0.025 moles 25 ml has o.025/4 molea or 0.00625 moles)
c How many moles of NaOH are needed to neutralize the H3PO4? (1 marks)
for every moles of H3PO4, WE NEED 3 MOLES OF NaOH. FOR 0.00625 MOLES WE NEED 3X 0.00625 =0.01875 MOLES OF NaOH
d) How many cm3 of 0.100 mol /l NaOH contain the moles in question 5(©) above? (1 marks)
1 L CONTAINS 0.100 Moles
100 ml contains 0.010Moles
we need 187.5 ml since (187.5 X 0.100)/1000=0.01875

Studying the brightness of a star can help scientist determine what part of the life-cycle a star is in. Is this true or false
Answer:
what do you mean?
Explanation:
Studying the brightness of a star can indeed help scientists determine what part of the life-cycle a star is in. The brightness of a star is directly related to its stage in the life cycle.The statement is true.
During the early stages of a star's life, it is formed from a cloud of gas and dust. As the star contracts under its own gravity, it starts to heat up and emits light. This is known as the protostar stage.
As the star continues to contract, it reaches a point where the core temperature becomes hot enough for nuclear fusion to occur. At this stage, the star enters the main sequence phase, where it will spend the majority of its life. The brightness of the star in this phase is determined by its mass. More massive stars are brighter than less massive ones.
As the star ages, it exhausts its hydrogen fuel in the core and begins to evolve. Depending on its mass, a star can become a red giant, a white dwarf, a neutron star, or even a black hole. Each of these stages has a different brightness profile.
By observing the brightness of a star over time, scientists can gather information about its age, mass, and evolutionary stage. This can provide insights into the star's life cycle and help in understanding the processes occurring within it.
Thus, studying the brightness of a star is an important tool for scientists to determine what part of the life cycle a star is in. By analyzing its brightness profile, scientists can gain valuable information about the star's age, mass, and evolutionary stage.The statement is true.

the mixing of which pair of reactants will result in a precipitation reaction?
Answer:
NH4Br and NH4I are both soluble in water, and they don't react with each other. So this pair will not form precipitation.
NaClO4 and (NH4)2S are both soluble in water. While in water, they dissociate into Na+, ClO4-, NH4+ and S2- ions, which don't react with each other. So this pair will not form precipitation.
Ni(NO3)2 and Na2CO3 are both soluble in water. When the 2 solutions combine, NiCO3 forms. NiCO3 is not soluble in water, so it will precipitate out from the solution. This pair will result in precipitation.
K2SO4 and Cu(NO3)2 are both soluble in water. While in water, they dissociate into K+, SO42-, Cu2+ and NO3- ions, which don't react with each other. So this pair will not form precipitation.
