6 0

1 mol of silver means 6.02 x 10²³ Ag atoms

number of moles of silver

= 2.408 × 10²⁴ Ag atoms x 1 mol Ag

6.02 x 10²³ Ag atoms

= 0.4 x 10

= 4 moles Ag

4 moles of silver are equivalent to 2.408 × 10²⁴ atoms

Is hydrogen the only non-metal positive ion?

rjkz [21]

Answer:

Why hydrogen is the only non-metal elements which loses electron to form positive ions ? ... When hydrogen bonded with most electronegative element then it forms a positive ions but when it bonded with less electronegative element then it forms a negative ion.

2 upper N upper O subscript 2 (g) right arrow 2 upper N upper o (g) plus upper O subscript 2 (g). Second: 2 upper N upper O (g)

The equation for the overall reaction obtained by adding these equations is; 2NO₂(g) ⇒ N₂O₄(g)

<h3>How to simplify chemical equations?</h3>

We are given equations;

2NO₂(g) ----> 2NO(g) + O₂(g) ---(1)

2NO(g) -----> N₂(g) + O₂(g) -----(2)

N₂(g) + 2O₂(g) ----> N₂O₄(g) -----(3)

Add eq 1 and eq 2 to get;

2NO₂(g) + 2NO(g) ⇒ 2NO(g) + O₂(g) + N₂(g) + O₂(g)

2NO will cancel out to get;

2NO₂(g) ⇒ N₂(g) + 2O₂(g) -----(4)

Add eq 3 to eq 4 to get;

N₂(g) + 2O₂(g) + 2NO₂(g) ⇒ N₂O₄(g) + N₂(g) + 2O₂(g)

This will reduce to;

2NO₂(g) ⇒ N₂O₄(g)

The correct question is;

Consider the chemical equations shown here.

2NO₂(g) ----> 2NO(g) + O₂(g)

2NO(g) -----> N₂(g) + O₂(g)

N₂(g) + 2O(g) ----> N₂O₄(g)

A team of geologists is surveying on a mountain. They come across a newly formed stream. The stream is flowing at an average rat

zhannawk [14.2K]

Answer:

35 minutes

Explanation:

The flow rate of the stream is the rate of volume of water with respect to time. It expresses the volume of water flowing per unit time.

Flow rate = $\frac{volume}{time}$

From the given question,

average flow rate of the stream = 420 cubic meters per minute, and the required volume = 14700 cubic meters.

So that;

time = $\frac{volume}{flow rate}$

= $\frac{14700}{420}$

= 35

time = 35 minutes

Therefore, with the given average flow rate, the steam will produce 14,700 cubic meters of water in 35 minutes.
