Answer:

c. inertia.

Explanation:

According to Newton’s First Law of Motion or the Law of Inertia a body at rest continues to be at rest unless acted upon by some force. A body in uniform motion continues to move in uniform motion unless acted upon by some external force. The external motion may change the uniform motion of the object.

Ag(s)+CN−(aq)+O2(g)→Ag(CN)−2(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. Express

Lerok [7]

Answer : The balanced redox reaction will be,

$4Ag(s)+8CN^-(aq)+O_2(g)+4H^+(aq)\rightarrow 4Ag(CN)_2^-(aq)+2H_2O(l)$

Explanation :

The given chemical equation is,

$Ag(s)+CN^-(aq)+O_2(g)\rightarrow Ag(CN)_2^-(aq)$

In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.

The half reactions in the acidic medium are :

Reduction : $O_2(g)+4H^+(aq)+4e^-\rightarrow 2H_2O(l)$ ......(1)

Oxidation : $Ag(s)+2CN^-(aq)\rightarrow Ag(CN)_2^-(aq)+1e^-$ .......(2)

Now multiply the equation (2) by 4 and then added both equation, we get the balanced redox reaction.

Thus, the balanced redox reaction will be,

$4Ag(s)+8CN^-(aq)+O_2(g)+4H^+(aq)\rightarrow 4Ag(CN)_2^-(aq)+2H_2O(l)$

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.
