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.

electronegativities of the elements be, mg, ca, and sr follow a specific trend within their group. based on this trend, the atoms of which element will have the least attraction for an electron?
Based on the trend of electronegativities values of the elements Be, Mg, Ca, and, Sr within their group (increasing from bottom to top), the atoms of the element Sr will have the least attraction for an electron.
We need to remember that electronegativity indicates the affinity or attraction of an element for an electron. Hence, the higher the electronegativity, the higher the attraction of that element for an electron.
The values of electronegativities of the given elements are the following:
Be = 1.57
Mg = 1.31
Ca = 1.0
Sr = 0.95
We can see that the increasing trend of electronegativities in this group is from the bottom to the top, having the Sr with the lowest electronegativity value and the Be with the highest.
This trend is related to atomic size, the larger the atomic size, the lower the electronegativity because the electron in the outermost shell will feel less attraction towards the nucleus of an atom. In a group of the periodic table, the size of an atom will increase from top to bottom.
Therefore, according to the said above, the atoms of the Sr will have the least attraction for an electron (it has the lower electronegativity value).

Which choice is an element? carbon dioxide water carbon air
Answer:
carbon
Explanation:
Considering the definition of elements ans compounds, carbon is an element.
Elements are simple substances that cannot be broken down by common chemical methods. The atoms in an element are the same as each other, yet they are different from those in other elements. In addition, the elements are represented by a symbol and can be found in the periodic table.
On the other hand, compounds are substances that are the result of the chemical union of two or more elements. This combination makes it impossible to identify each element by its individual and original properties. Compounds can be separated by chemical action.
In summary, the element is a pure chemical substance formed from an atom, which is characterized in that it cannot be divided or transformed by a chemical reaction. Whereas a compound is a pure chemical substance made up of a particular set of molecules or ions that are chemically bound together.
So, being:
carbon dioxide: composed of carbon and oxygen water: composed of two atoms of hydrogen and one of oxygenair: composed mainly of oxygen and nitrogenthen, carbon is an element.

at 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. what is the mass % of ammonium chloride in the solution? the formula weight of nh4cl is 53.50 g/ml.
At 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. The mass percent of the ammonium chloride in the solution is 2.003%.
The number of moles of a substance can be estimated as:
[tex]\mathbf{number\ of\ moles = \dfrac{mass}{molar \ mass}}[/tex]
Given that:
number of moles = 0.376 Mmolar mass of ammonium chloride = 53.50 g/mlMass = number of moles × molar mass
Mass = 0.376 × 53.50
Mass = 20.116 grams
In one mL of ammonium chloride; the grams of ammonium chloride is:
[tex]\mathbf{= \dfrac{20.116 \ grams}{1000 \ mL}}[/tex]
= 0.020116 g/mL
The mass of ammonium chloride in the solution can be computed as:
[tex]\mathbf{=(\dfrac{mass \ of \ NH_4Cl}{density \ of \ the \ solution})\times 100}[/tex]
[tex]\mathbf{=(\dfrac{0.020116 }{1.0045})\times 100}[/tex]
= 2.003%
Therefore, we can conclude that the mass percent of the ammonium chloride in the solution is 2.003%.

The element belongs to group 17 of the periodic table.
In the periodic table, elements are arranged in groups depending on their properties. Usually, elements whose atoms have the same number of valence electrons are placed in the same group.
All the elements in group 17 have seven electrons on their outermost shell. Since an ionization energies of the electrons on the valence shell of an atom are always close together, the ionization energies of the seven electrons as shown indicate that they must be on the same shell.
Hence, the new element must be a member of group 17 of the periodic table.

how are the light reactions and the calvin cycle connected?
Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.

Right a 5 sentence paragraph explaining this!!!
Answer:
,
Explanation:
Answer:
An atom is the smallest partical in the universe that makes up everything you see around you. Every chemical element is also made up of atoms. Since atoms are what give each element their defining characteristics, each element can be composed of multiple atoms but you must have all of the same type of atoms combined in order for it to be considered an element. For example the element gold can only contain gold atoms. If you mix the atoms of one element with the atoms of another your substance has then been changed from an element to a compound.

2. How many atoms of hydrogen do you have in the reactants? How many atoms of hydrogen to you have in the product?
3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?
1. No, it doesn't.
2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.
3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.
But on balancing the eqn,
CH4 + 2O2 > CO2 + 2H2O
The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.
