Answer 2

In this exercise, we have to use our knowledge of astronomy to identify the correct alternatives, so we find that:

1)C

2)B

3)A

4)B

5)D

6)C

Then, based on astronomy knowledge, we can identify that the true alternatives correspond to:

1)A meteor happen a streak of light above bring into being by a meteor superlative through Earth's general feeling or mood.

2)Meteoroids exist lumps of rock or iron that revolution the brightest star, just as celestial body orbiting a star, asteroids, and comets act.

3)A coma happen the fuzzy-anticipate glow that maybe visualize situated on sides the head of a comet.

4)Halley's Comet, that happen 8 kilometres (5 miles) expansive and 16 km long, travels around the Sun each 75 to 76 age in an lengthened circuit.

5)Shooting stars exist existent what astronomers call meteors. Most meteors upset fashionable the gases around the earth before they reach the ground.

6)The celestial body orbiting a star belt happen a torus-form domain in the Solar System, situated about middle from two points the orbits of the celestial body orbiting a star Jupiter and Mars.

What is the amount of diamine silver that can be formed when 10.00 g AgCl is mixed with 1.00 L of 0.100 M NH3?

Answers

The amount of diamine silver chloride = 8.87 g

Further explanation

Given

10 g AgCl

1.00 L of 0.100 M NH3

Required

the amount of diamine silver

Reaction

AgCl + 2 NH₃ → [Ag(NH₃)₂]Cl

mol AgCl :

= mass : MW

= 10 g : 143,32 g/mol

= 0.0698

mol NH₃ :

= M x V

= 0.1 x 1

= 0.1

NH₃ as a limiting reactant

mol [Ag(NH₃)₂]Cl based on NH₃ :

= 1/2 x mol NH₃

= 1/2 x 0.1

= 0.05

Mass diamine silver :

= 0.05 x  177.3822 g/mol

= 8.87 g
