8. An atom of element Z has the
electronic configuration 2.8.6. Which
one of the following statements
about element Z is correct? *
Answer:
See explanation
Explanation:
The question is incomplete but i will try to answer it to the best of my ability.
An element of configuration 2.8.6 is in group 16. This element will form a divalent anion Z^2-
Z is a nonmetal which combines with metals to form ionic bonds. Z can also react with other non metals to form covalent compounds.
Z is expected to have high electronegativity and electron affinity since it is a nonmetal of group 16.
The oxides of Z will dissolve in water to yield acidic solutions.

The temperature T in Kelvin is 273.15 more than temperature C in degrees Celsius. Use your function to find the equivalent temperature in Kelvin for 100*C.
Answer:
T(K) = 373.15 K
Explanation:
The kelvin is the base unit of temperature in the International System of Units (SI). The symbol used to express temperature in kelvins is K.
The temperature of zero kelvins is called the absolute zero. It is considered to be the lowest possible temperature, although nothing has reached it. The absolute zero (0K) is - 273.15 degrees Celsius.
This is the equation we can use to solve this question:
[tex]T(K) = T(C) + 273.15[/tex]
We have 100*C.
[tex]T(C) = 100 C[/tex]
[tex]T(K) = 100C + 273.15[/tex]
[tex]T(K) = 373.15 K[/tex]

What happens when A mixture of ammonia and oxygen is passed over platinum gauze heated to 800°C .
Answer:
The mixture forms nitrogen oxide and water upon reaction. However, 800 degree Celsius falls at higher limit of the process condition. It being an exothermic reaction, the reaction rate will be on the lower side than average.

2. An all natural mosquito repellent
is trying to make its way into the
market. One arm is sprayed with the
repellent and one arm is not sprayed
with anything. After 3 hours, the
number of mosquito bites is counted. What is the control group
Answer:
The arm that was not sprayed with anything
Explanation:
The control group would be the arm that was not sprayed with anything.
The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.

In the article, Invasion of the Periodical Cicadas, why do scienctists believe that cicadas only reproduce every 13 or 17 years? Explain your answer with evidence from the text.
Hi, you've asked an incomplete question. However, I assumed you are referring to the article found on the Scientific American website.
Explanation:
Remember, according to that article we are told that scientists notice that these insects have a long nymphal (immature form before becoming adults) stage, one that can last up to 13 to 17 years on the ground before they leave the ground looking for mating partners.
Because it is only after mating occurs at this point that their eggs are laid, that is why scientists believe that cicadas only reproduce every 13 or 17 years.

If a sample of nitrogen gas is compressed to fit in a smaller container, what happens to the
pressure, assuming the temperature remains constant?
Answer:
The pressure increases
Explanation:
In this action it is best to apply Boyle's law to resolve the problem. This is an interplay between Volume, Pressure and Temperature.
According to Boyle's Law "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant". Since the volume is being reduced to cram into the container, the pressure of the gases increases. In the smaller container, pressure rises and the volume reduces if temperature remains constant.Carbon monoxide (CO) burns readily in oxygen (O2), forming
carbon Dioxide (CO2). Which of the follow equations is shows

What is the molarity of a hydrochloric acid solution, when 30.0 mL is neutralized by 48.0 mL of 0.100 mol/L
calcium hydroxide?
The molarity of a hydrochloric acid solution : 0.32 M
Further explanationTitration is a procedure for determining the concentration of a solution by reacting with another solution which is known to be concentrated (usually a standard solution).
Titrations can be distinguished including acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases is used.
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence

According to the diagram which statement best describes what happens when two astronauts collide in space? Will give crown!!!!
Answer:
J. Their momentum is conserved
Explanation:
According to the diagram, the best statement that describes what happens when two astronauts collides in space is that their momentum is conserved.
The momentum before collision is 320kgkm/hr and after collision it is 320kgm/s
This collision is an inelastic collision;
momentum before = momentum after
m₁v₁ + m₂v₂ = v(m₁ + m₂)
m₁ = 80kg
v₁ = 4km/hr
m₂ = 80kg
v₂ = 0
v = 2km/hr
Insert the parameters;
(80 x 4) + (80 x 0) = 2(80 + 80)
320 = 320
Someone help me please i’ll give brainly
Answer:
Ionization
Melting
Vaporization
Explanation:
▶Ioniztion changes the charge of an electron, this usually happens between a chemical reaction. It takes a small amount of energy. Most of the time energy is absorbed instead of expelled!
▶ Melting changes the shape of the item and takes about 334 Joules/gram of energy.
▶ Vaporization changes the state of matter that the item is in and requires 2260 Joules/gram.

Consider the balanced equation below.
Upper P Upper C l Subscript 3 Baseline + Upper C l Subscript 2 Baseline right arrow Upper P Upper C l Subscript 5.
What is the mole ratio of PCl3 to PCl5?
Answer: The mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1
Explanation:
According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.
[tex]PCl_3+Cl_2\rightarrow PCl_5[/tex]
Thus in the reactants, there is 1 mole of [tex]PCl_3[/tex] and 1 mole of [tex]Cl_2[/tex] molecule. And thus there is 1 mole of [tex]PCl_5[/tex] in the product as well.
Thus the mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1
