Answer:
Specific examples of electrical energy include:
Alternating current (AC)
Direct current (DC)
Lightning
Batteries
Capacitors
Energy generated by electric eels
Explanation:
Electrical energy used for electric power, such as wall current used to power a light bulb or computer, is energy that is converted from electric potential energy. This potential energy is converted into another type of energy (heat, light, mechanical energy, etc). For a power utility, the motion of electrons in a wire produces the current and electric potential.
A battery is another source of electrical energy, except the electrical charges may be ions in a solution rather than electrons in a metal.
Biological systems also use electrical energy. For example, hydrogen ions, electrons, or metal ions may be more concentrated on one side of a membrane than the other, setting up an electrical potential that can be used to transmit nerve impulses, move muscles, and transport materials.

A sample of neon gas occupies a volume of 752 mL at 25 degrees Celsius. What volume will the gas occupy at -10 degrees Celsius?
Answer:
New volume v2 = 300.8 ml
Explanation:
Given:
Old volume v1 = 752 ml
Old temperature T1 = 25°C
New temperature T2 = -10°C
Find:
New volume v2
Computation:
Using Ideal gas law formula
V1T2 = V2T1
(752)(-10) = (V2)(25)
New volume v2 = 300.8 ml

Ocean water is salty. There are many type of salts (ionic compounds), but the salt that causes most of the saltiness in ocean water is sodium chloride (NaCl). (This is the same chemical as the table salt in your salt shaker.)
Use the concept of polarity to describe in detail how sodium chloride (NaCl) dissolves in ocean water.
Answer:
H2O is a polar molecule
the H is slightly positive and the O is slightly negative so the Na is attracted to the O side of the water molecule and the Cl is attracted to the H side of the water molecule
Explanation:
Define unbalanced forces(giving Brainly)
Answer:
Unbalanced forces are forces whose net amount is not zero.
This can take place when two equal forces are acting in the same direction or opposite direction but with different forces.
Unbalanced forces make some change in the position of the object on which force is exerted.

Plz help how do I predict the shape of the molecule for GaBr3
Explanation:
GaBr3 is called gallium tribromide. It is composed of one gallium atom and three bromide atoms. Within a molecule of gallium tribormide, there are three bonding electron pairs and zero lone pairs of electrons. Such a configuration results in the trigonal planar molecular shape.

Which charge kept the electrons in the atom?
Enter the answer
Check it
Answer:
hope it helps
Explanation:
Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Magnesium bromide (one magnesium atom with two bromine atoms) has a
chemical formula of MgBrz. If you look at the total atomic mass of MgBr2,
does magnesium or bromine make up more of the mass?
they are exactly the same
it is impossible to tell
magnesium
bromine
Answer:bromine
Explanation:
The mass of magnesium is 24 whereas 1 bromine atom is 80 (rounded up from 79.9) and there is 2 bromine atoms which means you have to multiply 80 by 2, giving you 160.

An unknown substance with a mass of 83 grams absorbs 1,108 J while undergoing a
temperature increase of 11 °C. What is the specific heat of the substance?
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c*m*ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case:
Q=1108 J c= ? m= 83 g ΔT= 11 CReplacing:
1108 J= c*83 g* 11 C
Solving:
[tex]c=\frac{1108 J}{83 g* 11 C}[/tex]
c= 1.21 [tex]\frac{J}{g*C}[/tex]
The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]

What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.
Answer:
m = 1.5 gram
Explanation:
Given that,
Density of protein gelatin, d = 3 g/L
The volume of protein gelatin, V = 0.5 L
We need to find the mass of the protein gelatin. The density of an object is given by :
d = m/V
Where
m is mass
[tex]m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g[/tex]
So, the required mass is 1.5 gram.
