Answer: the answer is b: sp3d
Explanation: BrF3 has a Bent T shaped structure with Br as a central atom bonded with three F atoms (three bond pairs) and two lone pairs. Hence , the hybridization would be sp3d. Br atom has 7 electron in its outer most shell. After the bond formation of BrF3 molecule we have 3 bond pairs+ 2 lone pairs
Answer:
long and confusing, but worth the watch
Explanation:
The answer would be:
<span>a microscope
a telescope
Both microscope and telescope make object become nearer and larger. This happens because both of them using a convex lens that will gather the light together. This kind of lens is used in eyeglasses with + diopter for hypermetropia patient. </span>
Answer: The definition of an endothermic reaction is that the products have higher energy than the reactants, resulting in a positive enthalpy of reaction.
Explanation:
Complete question:
A ball with a weight of 0.5 kg is sitting on a shelf that is 3 meters high. What is the gravitational potential energy of the ball ?
Help me! This is 8th grade sci btw
Answer:
the gravitational potential energy of the ball is is 14.7 J.
Explanation:
mass of the ball, m = 0.5 kg
height above the ground on which the ball is sitting, h = 3 m
The gravitational potential energy of the ball is calculated as follows;
P.E = mgh
P.E = 0.5 x 9.8 x 3
P.E = 14.7 J
Therefore, the gravitational potential energy of the ball is is 14.7 J.
