To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.
This name is made as follows:
The name of the metal is shown.The name of the non-metal is presented in abbreviated form.Add the suffix "ide" at the end.An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.
It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.

the bradford assay only works at low protein concentrations
Answer:
Dilute the sample
Explanation:
The statement is not entirely accurate. The Bradford assay is commonly used to determine protein concentrations in a sample.
However, it is true that the Bradford assay is more accurate and reliable for measuring protein concentrations at low to moderate levels rather than at very high concentrations.
The Bradford assay is based on the binding of Coomassie Brilliant Blue dye to proteins. The dye undergoes a color change from brown to blue when bound to proteins, allowing for the measurement of protein concentrations. At low protein concentrations, the binding of the dye to proteins is well-calibrated and results in a linear relationship between protein concentration and color intensity, making it suitable for accurate quantification.
At high protein concentrations, the binding capacity of the dye may become saturated, leading to non-linear and less accurate measurements. The excess protein can also cause interference and affect color development. In such cases, dilution or alternative protein quantification methods may be more suitable, such as the BCA assay or the Lowry assay.
Therefore, while the Bradford assay can be used to measure protein concentrations across a range of concentrations, it is generally more reliable for low to moderate protein concentrations.

the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emiting the excess energy as light which property of metals is explained by this?
Answer:
Lustrous
Explanation:
Metals are lustrous which gives them a property of having Shiny surfaces
The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.
What are valence electrons?Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.
When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.
Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.

How is a chemical equation different from mathematical equation?
Only chemical equation uses + sign
Only chemical equation uses arrow instead of = sign
Only chemical equation has numbers
Only chemical equation has minuses
Answer:
Only chemical equation uses arrow instead of = sign
Answer:
Only chemical equation uses an arrow instead of a = sign.
A chemical equation depicts a chemical reaction by utilising chemical formulae and symbols to depict the reactants, products, and chemical changes that take place. In a chemical equation, the arrow indicates the direction of the reaction and is commonly depicted as a single arrow pointing from the reactants to the products. In contrast, the equals sign (=) is commonly used in mathematical equations to indicate that two expressions have the same value.
While numbers are used to indicate the relative proportions of reactants and products and minus signs are used to indicate reactants or products in the form of ions, the arrow is the most distinguishing feature that distinguishes chemical equations from mathematical equations.

If 12.7 grams of hydrogen reacted with an unknown amount of oxygen, how many grams of water would be produced? (Write a balanced equation and show your work under the equation)
Answer:
2H2 + 1 O2 ------> 2H2O
m = 12.7g m = ?
Get the number of moles for Hydrogen gas (H2) by dividing the mass by the molar mass (1.01g/mol as listed in the periodic table for its atomic mass)
12.7/1.01 = 12.57 mol of H2
Now use the mole to mole ratio of Hydrogen gas (H2) and water (H2O).
From the balanced equation, we can see that 2 mol of H2 gives us 2 mol of H2O. Since both of the ratios are equal (2:2), the moles we have for hydrogen gas is the same as the moles we get for water.
12.57 mol of H2O
Now that we have the amount of mol for H2O produced in this reaction, we can convert it to grams by multiplying the moles by the molar mass.
Molar mass of H2O = (1.01 x 2) + (16) = 18.02g/mol
12.57 x 18.02 = 226.5g (rounded)
Therefore 226.5g of water will be produced in this reaction
According to law of conservation of mass and stoichiometry, 114.3 g of water are produced if 12.7 grams of hydrogen reacted with an unknown amount of oxygen.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
2 H₂ + O₂[tex]\rightarrow[/tex] 2 H₂O,according to this equation,4 g hydrogen reacts with 32 g oxygen to give 36 g water, thus 12.7 g of hydrogen will produce 12.7×36/4=114.3 g water and hence for this amount of water to be formed 12.7 g of hydrogen reacts with 101.6 g of oxygen which is obtained as 114.3-12.7=101.6 g
Thus, 114.3 g of water is produced.

Rubia was given a type of inclined plane called a ramp in her science class. Her teacher told her that the ramp should have a mechanical advantage of 3.
Rubia pulled a block up the ramp, but afterward she calculated that the mechanical advantage of the ramp was 2.8 instead of 3. Her teacher said she did not make a mistake. What did Rubia calculate?
A.
the actual operating power of the ramp
B.
the actual mechanical advantage of the ramp
C.
the ideal mechanical advantage of the ramp
D.
the ideal operating power of the ramp
Answer: B. The actual mechanical advantage of the ramp.
Explanation:
The professor saying that the ramp SHOULD have a mechanical advantage of 3 indicates that that would be the ideal mechanical advantage. Since Rubia calculated it to be 2.8, that means that it is the acutal mechanical advantage. The actual advantage will be reduced from the ieal due to things like friction.
