Answer:

Hi Todoroki here!!!

Explanation:

Chlorine has the electron configuration [Ne]3s 2 3p 5, with the seven electrons in the third and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell.

Your welcome!!

If 455 J of heat is transferred to 25.0g of water at 45.0 degrees Celsius, what is the final temperature of the water?

masya89 [10]

Answer:49.3

Explanation:4.1j/g c * 25g * (t2-45c)=455j

T2-45c = 455j/4.1j/g c * 25g

455/104.6

45+4.3= 49.3 celsius

Consider this reaction: 6 CO2 + 6 H2O + light equation C6H12O6 + 6 O2 If there were 2.38 x 102 g of H2O, 18.6 moles of CO2, and

alisha [4.7K]

H₂O would be the limiting reactant.

Balanced chemical equation:

6CO₂ + 6H₂O + light equation → C₆H₁₂O₆ + 6O₂

The amount of product that can be created is constrained by the reactant that is consumed first in a chemical reaction, commonly referred to as the limiting reactant (or limiting reagent).

Given

No. of moles of CO₂ = 18.6

Mass of H₂O = 2.38 × 10² g = 238g

No. of moles of H₂O = Given mass/ Molar mass

= 238 / 18 = 13.22 moles

Moles of H₂O = 13.22

According to the balanced chemical equation

6 moles of CO₂ react with 6 moles of H₂O

So the reactant that has less number of moles will be consumed first.

As the No. of moles of H₂O < No. of moles of CO₂

So, H₂O is the limiting reactant with 13.22 moles.

Hence, H₂O would be the limiting reactant.

A fictional cubed-shaped bacterium, Bacterius cubis, occupies a volume of 2.0 femtoliters. This particular type of bacteria is k

umka2103 [35]

Answer:

There are $\mathbf{8.90172 \times 10^{-14}}$ moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells

Explanation:

Given that:

The number of molecules present in one bacterial cell is $7.140 \times 10^3$ molecules

and the sample contains $7.512 \times 10^6$ molecules.

Number of moles = number of molecules /Avogadro's number

where;

Avogadro's number = 6.023 × 10²³

Number of moles = $\dfrac{7.140 \times 10^3}{6.023 \times 10^{23}}$

Number of moles = $1.185 \times 10^{-20}$ moles

So; $1.185 \times 10^{-20}$ moles is present in one bacteria cell

Similarly; the sample contains $7.512 \times 10^6$ molecules.

Therefore; the number of moles present in the bactoX is = $1.185 \times 10^{-20} \times 7.512 \times 10^6$

= $\mathbf{8.90172 \times 10^{-14}}$ moles

A compound is formed when 12.2 g mg combines completely with 5.16 g n. what is the percent composition of this compound? please

Brums [2.3K]

To get the percent composition of an element in a compound, simply divide the mass of the element by the total mass of the compound. And since we're going to need to calculate the percentage a couple of times, let's first start by calculating the total mass of the compound:
M = 12.2 g + 5.16g = 17.36 g
Now the percentage of magnesium:
12.2 g / 17.36 g = 0.702764977 = 70.3%
And the percentage of nitrogen:
5.16 g / 17.36 g = 0.297235023 = 29.7%
Magnesium = 70.3%
Nitrogen = 29.7%
