Element X has three electrons in its outermost orbit.
Element Y has seven electrons in its outermost orbit.
What is the chemical formula of the ionic compound formed by these elements when they react together? (Use X and Y as the chemical symbols.)
Answer: The chemical formula of the ionic compound formed by these elements when they react together is [tex]XY_3[/tex].
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here element X is having an oxidation state of +3 as it can lose 3 electrons from its outermost orbit called as [tex]X^{3+}[/tex] cation and element Y is having an oxidation state of -1 as it can gain one electron in its outermost orbit called as [tex]Y^{-}[/tex] anion. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]XY_3[/tex].

Can somebody help me?? “ what is the approximate frequency of this signal in this time window ?
Answer:
The approximate frequency of the signal is 12 Hertz
Explanation:
Frequency is defined as the number of complete cycles that passes a given point in a given time
One cycle is the motion that describes one complete rotation, such that one cycle is described by the region between successive crest or peaks
Therefore, we have from the diagram;
The number of cycles in 0.75 seconds ≈ 9 cycles
The number of cycles expected to pass in one second = 9 cycles/(0.75 seconds) = 12 cycles/second = 12 Hertz
The approximate frequency of the signal, f = 12 cycles/second = 12 Hertz.

The first inventors of the light bulb, Henry Woodward and Mathew Evans, faced which of the following problems?
The device was not very long lasting
The gas used in the light bulb was polsonous
The patent they tried to file for their invention was not accepted.
The nitrogen gas caused the light bulb to explode,
Answer:
The device was not very long lasting
Explanation:
Henry Woodward and Mathew Evans were two British scientist who invented first light bulb in 1860.
The challenge they faced while inventing light bulb was the log lasting light filament. Earlier filament was made up of carbonized paper which was not long lasting and has light for very less time period. Later they solve it by making carbon fiber filament derived from cotton and got patent for the same invention. But then because of financial issues they sold their patent to Edison.
Hence, the correct answer is "The device was not very long lasting".
Describe carbonation as it applies to the four-stroke engine.

why it is important to clean all mixing equipment out after mixing paint?
Answer:
Explanation:
It is important to clean your equipment to
1. Make it look good (like who wants dirty equipment right?)
2. You are at risk of leaving paint, which can get mixed into future paints, causing an ugly color.
3. If there are any toxic chemicals in the paint, it is good to clean them out just to make sure.
What is the structural stability formula?
Answer:
[tex]K=2J-R[/tex]
Explanation:
Let [tex]R[/tex] denotes the number of sides of a triangle.
Let [tex]J[/tex] denotes the number of joints.
Let [tex]M[/tex] denotes the number of members.
Let [tex]K[/tex] denotes the unknown to be solved.
Now write the structural stability formula:
[tex]K=2J-R[/tex]
Here, design is stable if [tex]M=K[/tex]
Design is unstable if [tex]M<K[/tex]
Design is indeterminate if [tex]M>K[/tex]

Which of the following sentences uses the word malleable correctly?
The gold wedding band was malleable, as it was shaped into a beautiful ring.
Functional designs are not malleable.
Plastic is a malleable substance that can conduct heat.
Ceramics are shaped by a malleable material.
Answer:
The sentence that uses the word malleable correctly is;
The gold wedding band was malleable as it was shaped into a beautiful ring
Explanation:
Malleability is the property of metal to have their shape changed by means of hammering, pressing or rolling so as to form sheets without them breaking such that the metals assume a new shape by compression
An example of a malleable metal is gold, which can be hammered into a gold leaf
Malleability in metals is due to their ability to have their nuclear shifted while maintaining their bonds due to the ability for electrons to move freely such that they are replaced with ease
Therefore, the sentence that uses the word malleable correctly is the gold wedding band was malleable such that it was able to be shaped into a beautiful ring.
1. How is high-speed internet typically transmitted around the world? over telephone wires b. through fiber optic cables c. beamed wirelessly to homes d via satellites
Answer:
High speed internet is typically transmitted around the world;
b. Through fiber optic cables
Explanation:
High speed internet is typically transmitted through fiber optic cables such as the Submarine Cables that makes connection through two cables that connects USA to Europe over the Atlantic Ocean, and the Middle East to Europe Terrestrial Cable Systems (MEETS) which is a cable network of 1,400 km and is being built to have an initial capacity of 200 Gbps
Other example of fiber optic cable assisted internet broadband transmission are the Diverse Route for European and Asian Markets (DREAM) terrestrial cable that connects Germany, Kazakhstan, Russia, and China, TEA NEXT that provides connection between borders on the East and West of Russia and Euro-Russia-Mongolia-China (ERMC) terrestrial cable
High-speed internet typically transmitted around the world through the use
of fiber optic cables.
Fiber optic cablesThese are connections which help transmit internet from one place to
another. It is a very fast method with a very low lag time. This is why it's used
for high speed internet transmission.
These cables are also able to withstand high traffic while other forms can't
do it thereby making option B the most appropriate.

Which of the following was one of the first uses of the electric light bulb?
as lights for Galloping Gertie
as searchlights at the New York World's Fair in 1893
as a searchlight at the Chicago World's Fair in 1893
as lights for the Tacoma Narrows bridge
Answer:
As lights for the Tacoma Narrows bridge
Explanation:
After Thomas Edison discovered electric appliances, light bulbs were produced for the streetlights as well. The first town in the United States to triumphantly display electric illumination was Cleveland, Ohio, with 12 electric lamps around the Public Square street system on April 1879. The light bulb served to stabilize social order after sundown.
