Answer;
Explanation;
-Hydraulic systems works on the idea that, unlike gasses, liquids cannot be compressed. Therefore, a system that transfers pressure through liquid to aid in the lifting of an object can be created.
-Force that is applied at one point is transmitted to another point using an incompressible fluid. This force is created on the piston which generates or creates a pressure that will be transmitted equally to all parts of the system, then to the load and this pressure creates a force that will lift the load on the load piston.
B) kinetic energy.
C) potential energy.
D) chemical energy.
Answer:
A) entropy
Explanation:
Answer:
Atomic Number = 3.
Explanation:
The number of protons determines the atomic number. Basically the number of protons is the exact same as the atomic number.
Protons 3 = Atomic number 3
Answer:
1. B Decantation. 2. D 3. B
Explanation:
This method is often used when dealing with mixtures of liquids or immiscible liquids with different densities
2. This is because the denser substance sinks to the bottom due to its higher density, while the less dense substance remains on the surface. It allows for the separation of the two substances based on their density.
3. The mixture is left undisturbed after the less dense substance has been poured off. This allows the denser substance to settle at the bottom while the lighter substance remains on top
4. It's a handy method for separating substances based on their density For example, if you have a mixture of oil and water, you can use decantation to separate the two. By letting the mixture sit undisturbed, the oil, being less dense, will float to the top, allowing you to carefully pour it off and separate it from the water.
Answer:
B. Lithium (Li)
Explanation:
Lithium forms an ionic compound with nitrogen with the general formula X₃N. When lithium and nitrogen react, they form a nitride called lithium nitride.
The Lithium nitride is actually prepared by the direct combination of elemental lithium with nitrogen gas. Below is the reaction equation:
6Li + N₂ → 2Li₃N
The reaction can occur when a solution of lithium in liquid sodium metal is treated with N₂. When the Lithium nitride reacts with water, it does that violently and produces ammonia.
(2) ionic and is formed by the transfer of two valence electrons
(3) covalent and is formed by the sharing of two valence electrons
(4) covalent and is formed by the transfer of two valence electrons
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.
In a covalent bond, atoms share electrons to complete their outer electron shell. In the case of a Br2 molecule, each Br atom has 7 valence electrons and needs 1 more electron to achieve a stable octet arrangement, so they share one pair of electrons to achieve this.
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.
