Barium fluoride(BaF2) is a chemical compound of barium and fluorine and is a salt. It is a solid which can be a transparent crystal.
Answer:
The distance traveled during its acceleration, d = 214.38 m
Explanation:
Given,
The object's acceleration, a = -6.8 m/s²
The initial speed of the object, u = 54 m/s
The final speed of the object, v = 0
The acceleration of the object is given by the formula,
a = (v - u) / t m/s²
∴ t = (v - u) / a
= (0 - 54) / (-6.8)
= 7.94 s
The average velocity of the object,
V = (54 + 0)/2
= 27 m/s
The displacement of the object,
d = V x t meter
= 27 x 7.94
= 214.38 m
Hence, the distance the object traveled during that acceleration is, a = 214.38 m
This path is called a circuit. Batteries<span> have three parts, an anode (-), a cathode (+), and the electrolyte. ... The chemical reactions in the </span>battery<span> causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode.</span>
If their average velocity is 55 mph Northwest, they won't arrive in Santa Fe.
First of all, the straight-line distance from Houston to Santa Fe is only 740 miles. And if the headed out from Houston going northwest and maintained that heading, then they passed about 135 miles north of Santa Fe.
Let's just work with SPEED, OK ?
If they drove 881 miles at an average speed of 55 mi/hr, then
the trip took them
(881 mi) x (hr / 55 mi) = 16.018 hours (16 hrs 1 min)
The valence electrons are the electrons in the outermost electron shell of an atom.
Explanation:
The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.
That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.
Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.
This tendency is called the octet rule, because the bonded atoms have eight valence electrons.
