below left is a cylinder containing water. an ball with a mass of 21g and a volume of 15 cm3 is lowered into the water. sketch the object and the new water level in the cylinder on the right.

Answers

You didn’t show the cylinder containing water, so I created one that you can use as a model (see image).

The water level was originally at 37 mL.

Then you added the ball, and it displaced its volume of water.

The new volume reading is 52 mL, so

Volume of ball = volume of displaced water = 52 mL – 37 mL = 15 mL.

Lowering a 21g ball with a volume of 15 cm³ into water in a cylinder raises the water level due to the displaced water volume, illustrating Archimedes' principle.

When a ball is lowered into a cylinder of water, it displaces water equal to its own volume, based on Archimedes' principle. The principle states that the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.

In this scenario, a ball with a mass of 21g and a volume of 15 cm³ is immersed in the water-filled cylinder. Initially, the water level in the cylinder is at a certain height. As the ball is lowered into the water, it displaces an amount of water equal to its own volume, causing the water level in the cylinder to rise.

The sketch on the right would depict the ball submerged in the water, and the new water level higher than the initial level. The increased water level is a result of the volume of water displaced by the submerged ball.

This phenomenon is essential in understanding buoyancy and the principle behind why objects float or sink in fluids. The upward force exerted by the water (buoyant force) counteracts the weight of the submerged object, leading to changes in water levels.

The product of the reaction is MgO. Describe what you observed in the reaction. Then consider the general AB form of a synthesis reaction. Write the chemical reaction, balancing the equation so that there are an equal number of atoms of each type in both the reactants and the product.

Answers

Answer:

2Mg + O₂ ⇒ 2 MgO

Explanation:

When the MgO formation reaction is carried out experimentally, it can be seen that Magnesium a solid that has a metallic luster, when a flame is brought closer so that the oxidation reaction of the metal occurs, it is appreciated that a colored flame is produced white for a few moments (the duration of the flame depends on the initial amount of magnesium) and when the reaction finished, the magnesium became a white solid, opaque and very fragile. This is because Mg reacted with oxygen and magnesium oxide formed, which is the white solid.

Synthesis reactions are those in which two or more reagents combine to obtain a new product compound. The general formula for this type of reaction is:

A + B ⇒ C

In the case of the example of the statement, the reaction form of this synthesis would be:

2Mg + O₂ ⇒ 2 MgO

The equation is matched in such a way that there is the same amount of atoms of each species in both reagents and products, thus respecting the principle of conservation of mass.

Clarification: In the synthesis reaction, oxygen is placed in its molecular form (O₂), because the compound is naturally found, it is a simple substance. Magnesium, on the other hand, is found as a simple substance as atoms.

The reaction between Magnesium and Oxygen produces Magnesium Oxide. The balanced equation is 2Mg + O2 → 2MgO.

In the reaction, Magnesium (Mg) reacts with Oxygen (O) to produce Magnesium Oxide (MgO).

The balanced chemical equation for this synthesis reaction is:

2Mg + O2 → 2MgO

In this equation, there are an equal number of atoms of each type on both sides of the equation, which follows the principle of conservation of mass.

What does the letters say acnsrl spgei
clue: a tool used to measure force!

Answers

The answer is spring scale

Final answer:

The jumbled letters 'acnsrl spgei' can be arranged to make 'Spring Scale', which is a physics tool used for measuring the weight or force exerted by an object.

Explanation:

The jumbled letters 'acnsrl spgei' can be rearranged to form the term'Spring Scale'. A Spring Scale is a tool used in Physics to measure the weight or force exerted by an object. It utilizes Hooke's Law, which states that the force exerted on a spring is directly proportional to the amount it is stretched or compressed. Thus, when you hang an object on a spring scale, the spring stretches, and the amount of stretch can be calibrated to the force or 'weight' of the object. In real-life uses, you may see it in a grocery store for weighing produce for example.

What are the two important jobs of photosynthesis

Answers

1. Photosynthesis is important because oxygen is released as a byproduct. We need that oxygen to survive. 

2. Photosynthesis helps get rid of the carbon dioxide in the air. Carbon dioxide, as you may probably know, is necessary for this process to occur.

It converts solar energy into chemical energy that is stored for later use.

Oxygen is created.

Answer:it is not wet

Explanation: while many people believe it is, it is only our imagination of how our body think water would feel like.

Water is wet that is why you have to dry off after going swimming or after you wash your hands you have to dry them because they are wet. I don't understand how people think water is dry because water is a liquid and wet.
