eimsori [14]3 years ago
6 0

Answer:

-2

Explanation:

Consider object is starting 12 units right from the reference point which is 0.

Assign the right direction positive sign.

when object is moving 14 units on left direction the position of object will be two units to the left side of reference point.

Assign the left direction negative sign position will be -2.

When the following molecular equation is balanced using the smallest possible integer coefficients, the values of these coeffici
Sergio [31]

<u>Answer:</u> The molecular balanced equation is written below

<u>Explanation:</u>

A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the decomposition of bromine trifluoride follows:

2BrF_3\rightarrow Br_2+3F_2

By Stoichiometry of the reaction:

2 moles of bromine trifluoride produces 1 mole of bromine gas and 3 moles of fluorine gas

Hence, the molecular balanced equation is written above.

Give the chemical symbol for the element with the ground‑state electron configuration [ Ar ] 4 s 2 3 d 1 . symbol: Determine the
Rus_ich [418]

Answer:

Sc (Scandium) has the given electronic configuration.

Explanation:

The given electronic configuration is [Ar]4s^{2}3d^{1}.

The last electron enters the d-subshell and hence is a d-block element known as Scandium with chemical symbol Sc.

For 4s subshell

n=4,l=0 and m ranges from -l to +l so m=0.

For 3d subshell

n=3,l=2 and m ranges from -l to +l so m can take values -2,-1,0,+1,+2

Note:

l values for subshells:

s : 0

p : 1

d : 2

f : 3 and so on.

What is the ph of a solution with [h3o+] = 1 × 10-9 m?
FrozenT [24]
PH scale is used to determine how acidic, basic or neutral a solution is
pH can be calculated using the H₃O⁺
ph can be calculated as follows
pH = - log[ H₃O⁺]
[H₃O⁺] = 1 x 10⁻⁹
pH = - log [1 x 10⁻⁹]
 pH = 9
pH of solution is 9

Which of these molecular electron configurations describe an excited state?
kherson [118]
<span>We have ground strate configurations of electrons,if electrons are filled in order of increasing energy. When there are electrons are in higher orbitals, we have an atom in an excited state. B, and C are excited states. In B, 2 electrons can fit in the 4s orbital, and that should fill fully before the 4p orbitals. In C, the same is true for 5s and 5p In D, this is not an excited state because 4s fills before 3d</span>
