A net worth: $79.0 billion.
Value of stock : $3.20 billion.
New net worth:
$79.0 + $3.20 = $82.20 billion = $82.20 * 10^9 = $8.20 * 10^10
Answer:
1. Hot water
2. A pile of wood shavings
Explanation:
Sugar can dissolve more quickly in hot water than in cold water because there is more energy in hot water molecules. Because they are moving faster, they have more energy to break the bonds that hold sugar together. There is also more energy available to break the hydrogen bonds that hold water together.
Wood shavings have a greater contact surface than the solid hunk of wood, which is why they have a higher calorific value and then they will catch fire more easily.
Answer:
Explanation:
1. Change object motion - unbalanced force
2. Push or pull - Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces. So if object move it is unbalanced.
3. Have direction - unbalanced force
4. Do not change objects motion - balanced force
5. Net force does not =0 - unbalanced force
6.net force =0 - balanced force
<h3>Answer:</h3>
Option-C: HCl + H₂O → H₃O⁺ + Cl⁻
Explanation:
Bronsted-Lowery concept of Acid and Base defines Acid as that specie which tends to donate H⁺ (Hydrogen Ion) and bases are those species which accepts H⁺ from Acids.
In selected option, HCl is reacting as Acid as it donates H⁺ to water (lowery bronsted base).
Also, the correspong acid is converted into conjugate base (i.e. Cl⁻) and base is converted into conjugate acid (i.e. H₃O⁺)
