Answer:
The answer is "Red- Lithium and Green- Copper".
Explanation:
The RedLithium is using in the batterie, which substituted the M12 and M18 lithium-ion packs as were first introduced in 2010. Milwaukee RedLithium power generation, in a nutshell, combines electronic systems, temperature resilience, or control that produce reliable, consistent electricity. This device outlasts all the other skilled battery cells, thinks faster, and works harder.
Its greenish light is a natural hue of a patina that forms over the surface layer; the patina covers its copper and produces a beautiful bluish-green facade shown on many copper rooftops or structures.
6. What category of elements is found between the metals and nonmetals
on the periodic table?
A synthetic
B. metalloids
C. radioactive
D. noble gases
Answer:
B. metalloids
Explanation:
The metalloids are found between metals and non-metals on the periodic table.
Metalloids have properties between those of metals and non-metals. Under certain prevalent conditions, they exhibit a set of properties.
Synthetic substances are those artificially made, they are not found on the periodic table.
Noble gases are found in the last group on the periodic table.
Radioactive substances are found in the lanthanide and actinide series.
86.30 mL of an HCl solution was required to neutralize 31.75 mL of 0.150 M NaOH. Determine the molarity of the HCI.
Answer:
0.055M
Explanation:
Using the formula as follows:
CaVa = CbVb
Where;
Ca = concentration of acid (M)
Cb = concentration of base (M)
Va = volume of acid (mL)
Vb = volume of base (mL)
According to the information given in this question, Ca (HCl) = ?, Cb (NaOH) = 0.150, Va (HCl) = 86.30mL, Vb (NaOH) = 31.75mL
Using CaVa = CbVb
Ca = CbVb ÷ Va
Ca = (0.150 × 31.75) ÷ 86.30
Ca = 4.7625 ÷ 86.30
Ca = 0.055M

How does light behave when it is shined on an object?
Answer:
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. For a smooth surface, reflected light rays travel in the same direction.

Find the molecular formula for CH that has a molecular weight of 65g.
Answer: Molecular Formula is C5H5
Explanation: M(CH) = 13.018 g/mol
Empirical formula of compound is (CH)x in which x = 2,3,4,...
Molar mass of the substance is 65 g. x = 65 g/mol : 13 g/mol = 5
If you start with 6 moles of N2 and 6 moles of H2 (meaning you won't have enough of 1 of the ingredients), how many moles of NH3 would you be able to make?
Answer:
[tex]4molNH_3[/tex]
Explanation:
Hello there!
In this case, according to the given information it will be firstly necessary to set up the chemical equation taking place:
[tex]N_2+3H_3\rightarrow 2NH_3[/tex]
We infer we need to calculate the moles of NH3 by using both of the moles of N2 and H2 at the beginning, in order to identify the limiting reactant:
[tex]n_{NH_3}=6molN_2*\frac{2molNH_3}{1molN_2}=12molNH_3\\\\ n_{NH_3}=6molH_2*\frac{2molNH_3}{3molH_2}=4molNH_3\\[/tex]
Thus, since hydrogen yields the fewest moles of ammonia, we conclude that we are just able to yield 4 moles of NH3.

The temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air. Given this information, which storm do you predict will have the most rainfall, and why?
Answer:
Tropical storm
Explanation:
The tropical storm have the most rainfall because tropical winds will increase in strength as temperatures rise. With the increase in temperature, the tropical storms have stronger winds which leads to produce higher rainfall. There is a direct relationship between temperature and amount of rainfall. As the temperature increases, the tropical storms have stronger winds which leads to more rainfall while on the other hand, decrease in temperature decrease the strength of the tropical storm's winds that leads to lower rainfall.
The temperature given shows that the storm that will be predicted is a tropical storm.
What is temperature?It should be noted that temperature means the degree of hotness or coldness in a body.
In this case, since the temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air, the appropriate storm is a tropical storm.

Calculate the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH. Below is the unbalanced equation: ______ HCl + _____ NaOH →____ H2O + _____ NaCl
Answer:
.496 M .
Explanation:
15.5 mL of .8 M NaOH will contain .0155 x .8 moles of NaOH
moles of NaOH = .0124 moles
For neutralization, moles contained by 25 mL of HCl = .0124
Hence molarity of HCl = .0124 / .025
= .496 M .
0.496 M is the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH.
What is molarity?Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Molarity = [tex]\frac{Moles \;solute}{Volume of solution in litre}[/tex]
15.5 mL of 0.8 M NaOH will contain 0.0155 x 0.8 moles of NaOH
Moles of NaOH = 0.0124 moles
For neutralization, moles contained by 25 mL of HCl = 0.0124
Hence molarity of HCl = [tex]\frac{0.0124}{0.025}[/tex]
= 0.496 M .
Hence, 0.496 M is the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH.

Calculate the specific heat capacity of the unknown metal given the
following information; the mass of the metal is 225 g, the temperature
raises by 13C and the energy absorbed was 1363 joules.
A. 0.466 j/gC
B.1.02j/gC
C.0.96 j/gC
D.2.14 j/gC
Answer: The specific heat capacity of the unknown metal given is [tex]0.466 J/g^{o}C[/tex].
Explanation:
Given: Mass = 225 g
Change in temperature = [tex]13^{o}C[/tex]
Heat energy = 1363 J
The formula used to calculate specific heat is as follows.
[tex]q = m \times C \times \Delta T[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat
[tex]\Delta T[/tex] = change in temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times \Delta T\\1363 J = 225 g \times C \times 13^{o}C\\C = \frac{1363 J}{225 g \times 13^{o}C}\\= 0.466 J/g^{o}C[/tex]
Thus, we can conclude that the specific heat capacity of the unknown metal given is [tex]0.466 J/g^{o}C[/tex].

Given the balanced equation representing a reaction:
H2SO3 + H2O « H3O+ + HSO3-
According to one acid-base theory, the H2SO3 molecules act as (AKS 5g)
Answer:
An acid because they donate H^+ ions
Explanation:
Let us look at the equation again;
H2SO3 + H2O « H3O+ + HSO3-
An acid donates hydrogen ion while a base accepts hydrogen ion. Hence, we have to look at which species that acted as hydrogen ion donors or acceptors.
We can clearly see that H2SO3 acted as a hydrogen ion donor while H2O acted as a hydrogen ion acceptor.
Thus, H2SO3 acted as an acid by donating hydrogen ions.
