Answer:
1 Hydrochloric acid is stored inside plastic containers.
Explanation:
Hydrochloric acid is a strong acid and is extremely reactive with metals, metal oxides, and skin. Proper storage is critical, because the acid can react with the storage container, and spillage can result in acid burns, particularly if the acid is extremely concentrated. That would be a chemical reaction.

5 To fight a bacterial infection, a patient was given an antibiotic to take for 10 days. After the
patient finished taking the antibiotics as directed, almost all the bacteria were killed. After
another 10 days, the patient was sick again with the same type of infection.
What most likely happened?
A A few bacteria survived the antibiotics and stopped reproducing.
B The patient’s high fever inactivated the antibiotic, allowing the surviving bacteria to grow rapidly.
C The antibiotic slowed the life cycle of the bacteria.
D Some of the bacteria were resistant to the antibiotic, and they reproduced.

Early one October you go to a pumpkin patch to select your Halloween pumpkin. You lift a 3.2-kg pumpkin to a height of 0.80 m to check it out. How much work do you do on the pumpkin when you lift it from the ground?
Answer:
2.56J
Explanation:
The work done in lifting up the pumpkin is 25.1 J.
We must know that the work done when the pumpkin is lifted up a distance of 0.8 m is obtained using the formula of work done under gravity. Hence, applying that formula;
Work done = mgh
m = mass
g = acceleration due to gravity
h = height
Work done = 3.2 Kg × 9.8 ms-2 × 0.80 m
Work done = 25.1 J

With electromagnetic induction, what are 3 things that can be done to increase the electric current?
-Use a stronger magnet.
-Increase the speed at which the magnet moves.
-Reduce the turns to the coiled wires.
-Add more turns to the coiled wires.
-Use a bigger magnet
Answer:
-Add more turns to the coiled wires.
-Increase the speed at which the magnet moves.
-Use a stronger magnet.
Explanation:
To increase the electric current in magnetic induction, add more turns to the coiled wires, use a stronger magnet, and Increase the speed at which the magnet moves, so options A, B, and D are correct.
What is electromagnetic induction?Utilizing the interaction between electricity and magnetism, electromagnetic induction creates a magnetic field around a single wire when an electric current flows through it. The magnetic field is substantially enhanced if the wire is twisted into a coil, creating a static magnetic field around itself in the shape of a bar magnet with a clear North and South pole.
As a result, a coil's ampere-turns are what decide how strong its magnetic field is. The coil's static magnetic field is stronger the more wire turns there are inside of it.
Therefore, to increase the electric current add more turns to the coiled wires, use a stronger magnet, and Increase the speed at which the magnet moves.

how many chickens would it take to ki ll an elaphant
??????????????????????????????????????????????????????????????????????????
Answer:
2207
Explanation:
A male elephant is about 6000kg, while the roosters of the golden comet chicken average on about 2,72kg. So if we divide 6000 by 2,72 we get about 2206 roosters for a draw. By this logic it would take 2207 chicken to kill an elephant

Humans are organisms that live on the surface of the Earth.
In recent years, many products that people use have released chemicals into the air. This has slightly changed the composition of the air that surrounds the planet.
Which statement describes this interaction?
A. The geosphere interacted with the hydrosphere.
B. The biosphere interacted with the atmosphere.
C. The hydrosphere interacted with the biosphere.
D. The atmosphere interacted with the geosphere.
Please answer fast! (^V^)
Answer:
the answer is c
Explanation:
The Biosphere interacted with the atmosphere. The biosphere represents the zone where all living organisms inhabit. Human beings are leaving organisms and they have released chemicals that change the composition of the atmosphere.
The hydrosphere represents the regions of the earth occupied by water and the geosphere is the solid layer that is the earth's crust.
