Explanation:
How many moles of NH3 can be produced from 3.76 moles of nitrogen
in the following reaction:
N2 (g) + 3 H2 (g) → 2 NH; (g)
The number of moles of NH₃ obtained from the reaction is 7.52 moles
The balanced equation is given below:
N₂ + 3H₂ —> 2NH₃From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Finally, we shall the number of mole of NH₃ produced by the reaction of 3.76 moles of N₂. This can be obtained as follow:
From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Therefore,
3.76 moles of N₂ will react to produce = 3.76 × 2 = 7.52 moles of NH₃.
Thus, 7.52 moles of NH₃ were obtained from the reaction.

A sample of a gas occupies 6.00 liters at a temperature of 200 K. If the pressure remains constant and the temperature is raised to 600 K, the volume of gas sample would be 1.)18.0 L 2.)2.00 L 3.)3.00 L 4.)12.0 L
Answer:
18
Explanation:
The volume of the gas should be 1. 18.0 L
Calculation of the volume of the gas;Since A sample of a gas occupies 6.00 liters at a temperature of 200 K. If the pressure remains constant and the temperature is raised to 600 K
So here the volume of the gas should be
= 600 * 6 /200
= 18.0 L

May I please have brainiest?
Answer:
The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1". In general it is known that nonmetals are very poor conductors of heat and electricity. The nonmetals that are solid are normally very brittle and has very little or no metallic luster at all. Nonmetals are highly reactive and show variety of chemical properties. It can also be pointed out that the nonmetals gain electrons very easily.

A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.
since 73% of the isotope is given, take 100%-73% to get the remaining % of the isotopes which is going to be 27%.
hence,
atomic weight= (73×59) + (27×62)
=4307+1302
=5609 amu

why does a liquid take the shape but not the volume of its container
Answer:
The attraction between the particles in a liquid keeps the volume of the liquid constant. The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume.

A.
The wind blew the freshly cleared dirt in the field away.
B.
The river was eroded the ground since the grasses and roots were removed.
C.
Animals dug into the freshly cleared dirt looking for food.
D.
The hot temperatures caused the ground to crack and fall apart.
Answer:
B, The river was eroded the ground since the grasses and roots were removed.
Explanation: when you have roots in the ground they would soak up the water but because he removed the roots, The water goes where it used to and it eroded the ground.

How is an atom’s atomic number related to its number of protons? To its number of electrons?
Answer:
The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.
Explanation:
make me as brain liest
Answer:Here u go!
Explanation:
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

The size of the gray circle represents atomic radius, or
the size of an atom. Which area of the periodic table
has elements with the largest atomic radius?
Answer: Here u go
Explanation:
Atomic radii varies in a predictable way across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

O It helps to break down food.
It surrounds and protects the brain.
It replaces the spinal cord in vertebrates.
O It allows for flexibility and movement.
It helps regulates water balance.
The answer is it supports body weight and it allows flexibility and movement
Answer:
A and E
Explanation:
Backbone is the part of skeletal system and is made of 26 vertebrae in total. The backbone and bones of lower limbs together serve to support the body's weight. Backbone surrounds and protects the spinal cord. Since the vertebrae of backbone are joints together by synovial joints, it allows the flexibility and movement of organisms.

A wireless server gives off 3.3 X 10-24 joules of energy. What is the wavelength of this server in meters?
Answer
A 22x10-57 m
B 60 X 10-52 m
5.0 X 100m
D 9.1 X1031m
Answer:
Wavelength = 0.06024 m
Explanation:
Equation of energy of wavelength from Einstein's relativity equation is;
E = hc/λ
Where;
h is Planck's constant = 6.626 × 10⁻³⁴ J. s
c is speed of light = 3 × 10⁸
We are given E = 3.3 × 10^(-24) J
Making wavelength λ the subject, we have;
λ = hc/E
Thus;
(6.626 × 10⁻³⁴ × 3 × 10⁸)/(3.3 × 10^(-24)) = 6.024 × 10^(-2) = 0.06024 m
Wavelength = 0.06024 m

The average mass atomic mass of neon is 20.179 u.
What is average atomic mass?
The total of an element's isotope masses, each multiplied with its natural abundance, equals the element's average atomic mass. The periodic table shows the average atomic mass.
Calculation of average atomic mass is shown as:
The average atomic mass will be calculated by the formula.
Average atomic mass = ∑ mass × abundance / 100
Given data:
neon-20 = 90.92%
neon-21 = 0.26%
neon-22 = 8.82%
Put the value of given data in average mass formula.
average mass formula = (90.92 × 20 ) +(0.26 × 21) + (8.82 × 22) / 100
average mass formula = (1818.4 + 5.46+ 194.04) / 100
average mass formula = 2017.9/ 100
average mass formula = 20.179
Therefore, the average mass atomic mass of neon is 20.179 u.
