<u>Answer:</u> The weight of the mouse on the Moon is 0.036 N

<u>Explanation:</u>

Weight is defined as the force exerted by the body on any surface. It is also defined as the product of mass of the body multiplied by the acceleration due to gravity.

Mathematically,

$W=mg$

where,

W = weight of the mouse

m = mass of the mouse = $22g=0.022kg$

g = acceleration due to gravity on moon = $1.625m/s^2$

Putting values in above equation, we get:

$W=0.022kg\times 1.625 m/s^2=0.036N$

Hence, the weight of the mouse on the Moon is 0.036 N

There are seventeen key nutrients essential for bone health. The ideal intake of calcium is approximately 1.75 g per day. How ma

baherus [9]

Answer:

2.63×10²² atoms

Explanation:

From the question given above, the following data were obtained:

Mass of calcium (Ca) = 1.75 g

Number of atoms of calcium (Ca) =?

From Avogadro's hypothesis,

1 mole of Ca = 6.02×10²³ atoms

Recall:

1 mole of Ca = 40 g

Thus,

40 g of Ca = 6.02×10²³ atoms

Finally, we shall determine the number atoms in 1.75 g of calcium. This can be obtained as follow:

From Avogadro's hypothesis,

40 g of Ca = 6.02×10²³ atoms

Therefore,

1.75 g of Ca = 1.75 × 6.02×10²³ / 40

1.75 g of Ca = 2.63×10²² atoms

Thus, 1.75 g of Ca contains 2.63×10²² atoms.

How many particles are in 1.40 x 10^7 mol of aluminum (Al)?

SpyIntel [72]

Answer:

<h3>Hlo there !! </h3>

<u>One mole of any substance contains 6.022*1023 structural units (atoms, molecules, ions, etc.). This number is known as the Avogadro constant.</u>

<u>One mole of any substance contains 6.022*1023 structural units (atoms, molecules, ions, etc.). This number is known as the Avogadro constant.So 1.04*107 mol of Al contains 1.40*107 * 6.022*1023 = 8.43*1030 structural units (in case of Al – atoms).</u>

<h3><u>8.43*1030 particles Al.</u></h3>

According to valence bond theory, which orbitals on N and H overlap in the NH3 molecule? 2p on N overlaps with 2s on H 2s on N o

Alecsey [184]

Answer:

$sp^{3}$ on N overlaps with 1s on H.

Explanation:

Hybridization of central atom generally can be found by finding the hybridization number.Hybridization number is the sum of number of lone pairs and number of sigma bonds.

If hybridization number is 2 then the central atom is sp hybridized.

If it is 3 it is $sp^{2}$ hybridized.

If it is 4 it is $sp^{3}$ hybridized and so on.

Here in $NH_{3}$ molecule there are 3 sigma bonds and one lone pair(see the figure attached).

Hence hybridization number is 4 and hence it is s $p^{3}$ hybridized.

And in case of hydrogen atom the only electron of it resides in the 1s orbital.

Therefore $sp^{3}$ on N overlaps with 1s on H.
