Which of these is always equal to the molar mass of any element?its atomic number
its atomic weight
its atomic formula
its atomic structure

Answers

Answer 1

Answer:

Answer: Option (b) is the correct answer.

Explanation:

Atomic weight is also known as atomic mass or molar mass of an atom.

Atomic mass means the sum of total number of protons and neutrons present in an atom.

For example, atomic mass of HCl is atomic mass of hydrogen + atomic mass of chlorine.

That is, atomic mass of HCl is 1.01 g/mol + 35.453 g/mol = 36.463 g/mol

Thus, we can conclude that molar mass of any element is always equal to its atomic weight.

Answer 2

Answer: atomic weight, as it is essentially the same as mass

F(newtons)=m(kg) x a(m/s2) Please show work.

Answers

Well, you could get the mass as $m=(G_0)/(g_0)$ ad then $g_1=(G_1)/(m)$ , where $G_0$ is the sea level weight, $g_0$ the sea level accel., $g_1$ the accel. above while $G_1$ the weight above.

Answer:

Well, you could get the mass as m=\frac{G_0}{g_0} ad then g_1=\frac{G_1}{m}, where G_0 is the sea level weight, g_0 the sea level accel., g_1 the accel. above while G_1 the weight above

Please! Which statement correctly describes glucose (C6H12O6)?
A)It is made of matter and contains twenty-four molecules.
B)It is an element made of three types of atoms.
C)It is an atom made up of carbon, hydrogen, and oxygen.
D)It is a compound made of twenty-four total atoms of three different elements.

Answers

Answer:

The correct answer is D)It is a compound made of twenty-four total atoms of three different elements

Explanation:

Glucose (C₆H₁₂O₆) is a molecule (not an atom neither an element, so the options B and C are not completely correct). It is composed by three different elements (oxygen: O, carbon: C and hydrogen: H), and it has twenty-four atoms in its molecule: (6 x C) + (12 x H) + (6 x O)= 24. So, the option D is the one that best describes glucose.

C) it is made up of carbon, hydrogen, and oxygen

D) it is a compound made of twenty-four total atoms of three different elements

they are both right but I would go with D

Each sheet of metal on a roof is parallel to the rest of the sheets of metal. If the first sheet of metal is perpendicular to the top line of the roof, what can you conclude about the rest of sheets of metal? Justify your answer.a. The sheets of metal are all perpendicular to the top line of the roof by the Alternate Interior Angles Theorem.
b. The sheets of metal are all perpendicular to the top line of the roof by the Transitive Property of Parallel Lines.
c. The sheets of metal are all perpendicular to the top line of the roof by the Converse of the Same-Side Interior Angles Theorem.

Answers

B.

Because all of the lines are parallel, and the top line is perpendicular to them, all of the lines are perpendicular to the top line due to the transitive property of parallel lines.

Answer:

b. The sheets of metal are all perpendicular to the top line of the roof by the Transitive Property of Parallel Lines.
