Answer:
Atoms form two types of bonds: ionic bond and covalent bond. In a covalent bond, valence electrons are shared; in an ionic bond, valence electrons are transferred.
Explanation:
Therefore, the answer is A
Answer:
The acceleration of the box is 2.
Explanation:
According to Newton's second law of motion, the acceleration of any object will be directly proportional to the net unbalanced force acting on the object and inversely proportional to the mass of the object.
Net force = Mass × Acceleration
So
Since in this case, the box is experiencing a force from east of magnitude 27 N and resisting force of about 17 N from west. So the net force will be the difference of acting and reacting force.
Net force = 27-17 = 10 N.
Thus,
So 2 is the acceleration of the box. Thus the magnitude of acceleration of the box is 2.
(2) moving and neutral
(3) stationary and charged
(4) stationary and neutral
Answer:
the correct answer is 1 moving and charged.
Explanation:
Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus.
Considering the definition of percentage by mass, the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 grams of water is 6.25 %.
The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:
In this case, you know:
Replacing:
Solving:
percent by mass= 6.25 %
Finally, the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 grams of water is 6.25 %.

Hello!
What the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 g of water?
We have the following data:
m1 (solute mass - iron II sulfate) = 5.0 g
m2 (solvent mass - water) = 75.0 g
m (solution mass) = m1 + m2 = 5.0 + 75.0 = 80.0 g
%m/m (percent mass by mass) = ?
We apply the data to the formula
Answer:
The percent by mass of solute and mass solution of Iron II Sulfate is 6.25%

water pressure
Answer: The potential of electrons in a circuit can be increased by the action of the battery.
Explanation:
A battery is a source of energy. It provides push to voltage so that the current can flow in the circuit.
For example, the electrical energy is used by the bulb connected in the circuit. The electrical energy is provided by the battery. If the energy of the battery is used up then no current will flow in the circuit. Then the bulb will not glow in this case.
Therefore, the potential of electrons in a circuit can be increased by the action of the battery.
