Water is H2O, so 2 molecules of Water will be 2H20
mario62 [17]4 years ago
4 0

Answer: 2H2O

Explanation:

Water is made up of Hydrogen and Oxygen. The symbol of Hydrogen is H but it cannot exist as monoatomic gas when combined with oxygen but diatomic therefore it is represented as H2. The symbol of Oxygen is O.

Combining both will give us the chemical symbol of water which is H2O(which is just one molecule of water)

2 molecules of water will then give us 2H2O.

A laser emits a green light with wavelength of 515 nm. Calculate the frequency of this light.
pentagon [3]

Answer:

Frequency=5.83\times 10^{14}\ Hz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 515 nm

Also, 1 m = 10^{-9} nm

So,  

Wavelength = 515\times 10^{-9} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{515\times 10^{-9}}\ Hz

Frequency=5.83\times 10^{14}\ Hz

These are the photos for part A
Alla [95]

Answer:

Explanation:

For part C, this should be what the graph looks like.

The reactants should have higher energy that the products so that it can release energy. Recall the reaction is N2 + 3H2 => 2NH3 + energy, making it exothermic. Apparently, you are supposed to adjust the energy diagram on the simulation so that 20% of the reactants become the products.

amm1812

Answer:

294,3

Explanation:

E=m*g*h

While g = 9,81 m/s^2 then:

E=2[kg]*9,81[\frac{m}{s^2} ]*15[m]=294,3 [J] [J]
