4 0

Answer:

Explanation:

use the equation

moles = mass/mr

=19.9/79.5

=0.250moles of CuO

then do the same for

H = 2.02/1

=2.02

so CuO is the limiting reagent because there is less amount of it.

Hope this helps  :)

A radio station broadcasts at a frequency of 590,000 Hz. What is the wavelength of the radio waves?​
34kurt

Answer:

f = frequency = 590,000 Hz ===> 59×10^4 Hz

λ = Wavelength = ?

c = Speed of light in a vacuum = 3 × 10^8 m/s

** Hz = 1/sec

___o___o___

f =  \frac{c}{λ}  \\  \\ λ =  \frac{c}{f}  \\  \\ λ =  \frac{3 \times  {10}^{8} }{590000}  \\  \\ λ =  \frac{3 \times  {10}^{8} }{59 \times  {10}^{4} }  \\  \\ λ =0.0508  \times  {10}^{4}  \: m \\  \\ λ = 508 \times  {10}^{ - 4}  \times  {10}^{4}  \: m \\  \\ λ = 508  \: m

(35 points) ROCK TYPES. If you help me with this I'll love you forever
4vir4ik [10]

There are so many rock types around! Though, with all the rock types.. there are a few that we study within grade school and such. These types of rocks are,

-Igneous // Igneous rock is formed through the cooling and solidification of magma or lava.

-Sedimentary // Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

-Metamorphic //  The original rock is subjected to heat and pressure, causing profound physical or chemical change.
