The bond formed when electrons are shared is called a(n) _____.
zhuklara [117]

Answer : Option D) Covalent bond.

Explanation : The bond formed when electrons are shared is called a covalent bond.

A covalent bond which is also called as molecular bond, is a chemical bond which involves mainly the sharing of electron pairs between atoms. These electron pairs are called as shared pairs or bonding pairs, which are stable balance of attractive and repulsive forces between atoms, when these bonding pairs share electrons, it is called as covalent bonding.

Covalent bonding is usually seen in non-metals which share their electrons while bonding.

A space probe on the surface of mars sends a radio signal back to earth,a distance of 7.19 ×10⁷ km. Radio travel at the speed of
lys-0071 [83]

Answer:

240 seconds

Explanation:

Data Given:

Distance Radio travel to earth = 7.19 ×10⁷ km

Speed of this radio signal = 3.00 ×10⁸ m/s

Solution:

First convert Km to m

1 km = 1000 m

7.19 ×10⁷ km = 7.19 ×10⁷ x 1000 = 7.19 × 10¹⁰m

Formula used to calculate time

            Speed (S) = distance (d) / time (t)

rearrange above equation for time

            time (t) = distance (d) / Speed (S) . . . . . . . . .(1)

Put values in equation 1

            time (t) = 7.19 × 10¹⁰/ 3.00 ×10⁸ m/s

            time (t) = 240 s

So 240 seconds it take for the signal to reach the earth

Consider the following reactions and their respective equilibrium constants: NO(g)+12Br2(g)⇌NOBr(g)Kp=5.3 2NO(g)⇌N2(g)+O2(g)Kp=2
maxonik [38]

Answer:

Equilibrium constant of the given reaction is 1.3\times 10^{-29}

Explanation:

NO+\frac{1}{2}Br_{2}\rightleftharpoons NOBr....(K_{p})_{1}=5.3

2NO\rightleftharpoons N_{2}+O_{2}....(K_{p})_{2}=2.1\times 10^{30}

The given reaction can be written as summation of the following reaction-

2NO+Br_{2}\rightleftharpoons 2NOBr

N_{2}+O_{2}\rightleftharpoons 2NO

......................................................................................

N_{2}+O_{2}+Br_{2}\rightleftharpoons 2NOBr

Equilibrium constant of this reaction is given as-

\frac{[NOBr]^{2}}{[N_{2}][O_{2}][Br_{2}]}

=(\frac{[NOBr]}{[NO][Br_{2}]^{\frac{1}{2}}})^{2}(\frac{[NO]^{2}}{[N_{2}][O_{2}]})

=\frac{(K_{p})_{1}^{2}}{(K_{p})_{2}}

=\frac{(5.3)^{2}}{2.1\times 10^{30}}=1.3\times 10^{-29}
