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.

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].

Answer:

false

Explanation:

i think the answer is false

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]

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.

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".

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.
