Answer:
D.<em>The</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>waves</em><em> </em><em>that</em><em> </em><em>pass</em><em> </em><em>a</em><em> </em><em>point</em><em> </em><em>in</em><em> </em><em>1</em><em> </em><em>(</em><em>per</em><em>)</em><em> </em><em>second</em>
Answer:
D= 5 g/L
Explanation:
M= D x Vm
M is the molar mass = 112g/mol
D is the density
Vm is the molar volume whuch is 22.4L at STP
now substitute;
112 = D x 22.4
D= 112\22.4
D= 5 g/L
Answer:
Explanation:
Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mass of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.
Answer:
B. hexane
Explanation:
Im not sure I just goggled it
The isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions because the nuclear reactions involve changes to protons and neutrons in an atom and isotopes differ in neutrons and so they react differently to nuclear changes. While for chemical reactions, the electrons in an atom are involved but the isotopes do not differ in electrons and so they react the same way during chemical changes.
Answer: Option A & C
<u>Explanation:</u>
The reactants of chemical and nuclear reactions are different. The reactants of chemical reactions are the electrons present in the outermost shell of the reactants, while the reactants of nuclear reactions are either the nuclei of reactants or a nuclei and any subatomic particles of other reactants.
Thus it can be understood that chemical reactions consider the electrons while nuclear reactions consider the nuclei or the number of protons and neutrons of the reactants.
The isotopes of elements contain different mass number or we can say different number of neutrons but the number of electrons are same, so they behave differently in nuclear reactions and similar in chemical reactions.
