The percent concentration of the Barium nitrate : 11.33%

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

\tt \%mass=\dfrac{mass~solute}{mass~solution}\times 100\%

mass solute=mass Barium nitrate(Ba(NO₃)₂)=46 g

mass solvent=mass water=360 g

mass solution=mass solute+mass solvent=46+360=406 g

\tt \%mass=\dfrac{46}{406}\times 100\%\\\\\%mass=\boxed{\bold{11.33\%}}

for example,

A-B + C -------> A-C + B

electropositive replaces only electropositive elements from compound. same is true for electronegative element

in first reaction I being electro negative replaces Br from KBr so this is a single displacement reaction

Satellites equipped with ultraviolet telescopes gather data about galaxies .<br><br> TRUE OR FALSE?
Anna71 [15]

Answer:

True.

Explanation:

Here is an example: Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes.

Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. Its gaze has helped determine the age of the universe, the identity of quasars, and the existence of dark energy.

Describe how the air pressure on Earth affects the weather.
11111nata11111 [884]

Answer:  

As the pressure decreases, the amount of oxygen available to breathe also decreases. Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather.
