Satellite acts as a relay station for earth sources. A transmission station sends the information to the satellite, which in turn retransmits to the receiving stations. The original signal being transmitted from the earth station to the satellite is called uplink of 6 GHz The retransmitted signal from the satellite to the receiving station is called downlink of 4 GH frequency. The transponder is the transmitter-receiver combination in a transponder.

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dio

Sidana [21]

Explanation:

The glucose molecules changes as following:

C6H12O6 —> C2H5OH + CO2

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

A chemist is using a solution of hno3 that has a ph of 3.75. what is [h ] for the solution?

NemiM [27]

$\text{pH} = -\log[H^{+}]\\\\\implies \log[H^{+}] = -\text{pH}\\\\\implies [H^{+}] = 10^{-\text{pH}}}\\\\\implies [H^{+}] =10^{-3.75}=0.00017~M$

Identify the parts of the atom that are labeled in the diagram

baherus [9]

Answer:

A- Nucleus

B-Energy levels

Explanation:

An atom refers to the smallest particle of an element that can take part in a chemical reaction.
An atom is made up of two major parts namely; the nucleus and the energy shell or energy levels.
The nucleus of an atom contains the sub atomic particles, protons and neutrons while the energy shells contain the sub atomic particle electrons.
It is important to note that the protons in the nucleus are positively charged which makes the nucleus to be positively charged.
On the other hand, energy shells are negatively charged because of the negative charge of the electrons.
