Answer:

wavelength = 345.62 m

Explanation:

Given that,

Frequency of signal, f = 868 kHz

We need to find the wavelength of its signal.

The relation between wavelength and frequency is given by :

c=f\lambda

c is speed of light

\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{868\times 10^3}\\\\\lambda=345.62\ m

So, the wavelength of its signal is 345.62 m

Answer:

The answer to your question is given below

Explanation:

The balanced equation for the reaction is given below:

CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)

1. Writing an expression for the equilibrium constant, K.

The equilibrium constant, K for a reaction is simply the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.

Thus, we can write the equilibrium constant, K for the reaction as follow:

CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)

K = [CaCO3] [H2]⁴ / [CaO] [CH4] [H2O]²

2. Based on the value of K, more products will be in the equilibrium mixture since the value of K is a positive large number.

lesya [120]
Global warming affects many processes in biological ecosystems. Different species of flora and fauna change their habitats and geographical areas according to climate change and specific geographical environments. Areas of occurrence of specific species, for example insects in terrestrial areas and fish and arthropods in the seas and oceans, change. Bird habitats change, so migrations of some bird species may also be subject to modification. In the situation when forest areas dry out and turn into steppes and deserts, changes in natural habitats and areas of occurrence of species change and concern simultaneously many species of flora and fauna.

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5
djyliett [7]

Question:

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5 hydroxyl group?  

a. disaccharide

b. carboxylic acid

c. hemiacetal

d. ester

e. stereoisomer

Answer:

hemiacetal  forms in the intramolecular reaction between the aldehyde portion of the glucose molecule and its C-5 hydroxyl group

Explanation:

It is an alcohol also an ether that has been attached to the carbon molecule. Here the hydrogen has occupied the fourth bonding position. This hemiacetal has been derived from the aldehyde. Hence, hemiketal being an alcohol as well as ether has been attached to the same carbon and also to the two other carbon.
