Answer: stable unmetal
Explanation: if you count electrons, you get 35 and it is element Br
According to the electronic configuration , the element with the given electronic configuration is a unstable non metal.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

C9H20+14O2→9CO2+10H2O a. How many molecules of nonane will burn in a tank that has 770 mL of oxygen at STP? b. If the container were heated to 78O C before the combustion, what would the pressure be?
Explanation:
C9H2O + 14O2 → 9CO2 + 10H2O
a. How many molecules of nonane will burn in a tank that has 770 mL of oxygen at STP?
From the reaction;
1 mol of nonane reacts with 14 mol of Oxygen
At STP, 1 mol = 22.4 L
Converting 770 ml (0.77 L) to mol;
1 = 22.4
x = 0.77
x = 0.77 / 22.4 = 0.034375 mol
Back to the equation;
1 mol = 14 mol
x mol = 0.034375 mol
Solving for x;
x = 0.034375 * 1 / 14
x = 0.00245535714 mol
1 mol = 6.022 * 10^23 molecules
0.00245535714 mol = x
Solving for x;
x = 0.00245535714 * 6.022 * 10^23
x = 1.4786 * 10^21 molecules
b. If the container were heated to 78O C before the combustion, what would the pressure be?
Initial Pressure P1 = ?
Initial Temperature T1 = 780 +273 = 1053 K
Final Temperature (STP) T2 = 273 K
Final Pressure (STP) P2 = 1 atm
Using gay lusaac's law;
P1 / T1 = P2 / T2
Inserting the values;
P1 = T1 * P2 / T2
P1 = 1053 * 1 / 273
P1 = 3.857 atm
Find the net force on a rope which is being pulled by 2 groups of
students. The blue team is pulling with a force of 1500 N to the west and
the orange team is pulling with a force of 1300 N to the east.
Answer:
200 N to the west b/c we have 1500 to west and
1300 N to east . the forces have a opposite direction.
thus we add the force. and we gain 200N force.

How do mountains affect the climate of a region?
(Giving brainlist for a summary and correct answer)
Answer:
Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop
Answer:
Mountains effect them with contact
Explanation:
They are always pushing eachother and crash
From this list below, select the items which are properties of ionic compounds. * 5 points low melting point conductors of electricity when in liquid or aqueous state high melting point mostly liquids and gases at room temperature soluble in water
Answer:
conductors of electricity when in liquid or aqueous state
high melting point
soluble in water
Explanation:
An ionic substance is any substance that is composed of two ions of opposite charge.
In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.
All ionic substances have a very high melting point and dissolve in water easily.

If 4.36 mol of potassium phosphate react, how many grams of barium phosphate are produced?
Hello Mistyann!
First you need to know amount of barium phosphate is
Half of potassium phosphate, also 2.18 mol.
Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol
You can calculate it yourself dear.
Now mass is amount of substance · molar mass.
It has been an honour to teach you, dear,
God bless!
Identify at least four limiting factors in the local ecosystem and their impact on native populations.
4 limiting factors could be water, space, pollution, and access to mates, could all be factors in limiting the native population. Water, could be affected by pollution, and this would remove water, which means that no living things would be able to survive, or at the best be hindered in its growth. Space could be removed by deforestation, or simple water rising, and this could kill off the population, thus removing mates for the population. (hope this helped, if it did, please consider marking brainiest)
The availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.
What are the limiting factors?The limiting factors such as availability of food, water, shelter and diseases can change animal and plant populations because these factors has a direct impact on the organisms and the organisms is depend on these factors for their survival.
So we can conclude that availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.

1. A balloon has 1.55 L of air in it exerting a pressure of 105.2 kPa. At
constant temperature, if the pressure increases to 122.0 kPa, what is the
volume?
Answer:
[tex]V_2=1.34L[/tex]
Explanation:
Hello there!
In this case, since this problem is describing how pressure changes as a function of volume and vice versa, it is possible recall the Boyle's law as shown below:
[tex]P_1V_1=P_2V_2[/tex]
Whereas we are asked to compute the volume when the change is pressure is performed (V₂); thus, we proceed as follows:
[tex]V_2=\frac{P_1V_1}{P_2}\\\\V_2=\frac{1.55L*105.2kPa}{122.0kPa}\\\\V_2=1.34L[/tex]
