Equal forces acting on one object in opposite directions are called balanced forces

Answers

Answer 1

Answer:

True

Explanation:

Forces, equal in magnitude and opposite in direction, and cancel each other out are called Balanced Forces.

Balanced Forces DO NOT cause any change in the velocity of the object, but the Object may correspond to a change in shape or size.

Example :

Blasting a balloon by compressing it tightly with both hands, roughly with an equal force, is a practical example of Balanced Forces. In this case, the balloon before the burst stays at a state of rest and same after the burst. But the burst or the compression, causes a change in the shape of the balloon.

Yule logs are commercially available that burn with a red and green flame. What two chemicals could produce this effect?

Answers

Answer:

Strontium chloride: Makes a red flame.

Strontium sulfate: Makes a green flame.

Copper salts (such as copper sulfate or copper chloride) and barium salts (such as barium chloride or barium nitrate) can produce a red and green flame when burned.

The colors of flames are often determined by the presence of specific chemicals or elements that emit characteristic wavelengths of light when heated. In the case of red and green flames, copper and barium salts are commonly used.

Copper salts, particularly copper sulfate or copper chloride, can produce a green flame when burned. This is due to the emission of specific wavelengths of green light by excited copper ions in the flame.

Barium salts, such as barium chloride or barium nitrate, can produce a red flame when burned. The red color is caused by the emission of specific wavelengths of red light by excited barium ions in the flame.

When these two chemicals are combined in a yule log or firework formulation, they can create a visually appealing display of red and green flames. The copper and barium ions are heated and excited by the flame, releasing their characteristic colors of light. It is important to note that the production of colored flames should be done with caution and adherence to safety guidelines to ensure proper handling and disposal of chemicals.

Many ladybird beetles live in Pedro's garden. He observed them one summer for a science project. Pedro noticed that all the ladybird beetles had red shells. Some of the beetles had many dark spots, some had only a few dark spots, and one or two beetles had no dark spots at all. Around the same time, Pedro's father replanted the garden using just red flowers. A few years later, Pedro observed the ladybird beetles again. This time he noticed that almost all the ladybird beetles had shells with more red visible. They had few or no dark spots on their shells. Pedro concluded that replanting the garden with red flowers caused a change in the ladybird beetle population. Which best explains Pedro's observations?

Answers

Answer:

No.

Explanation:

No, Pedro's observations does not suggest that replanting the garden with red flowers caused a change in the ladybird beetle population because the colour of flower has no effect on the change in the population of ladybird beetle, it must be occur due to the dominant genes present in the population of ladybird beetle. This dominant genes is responsible for the presence of more red colour on the ladybird beetles shells.

How many moles of H2 are produced when 2.54 moles of H2O reacted?

Answers

Answer:

2.54mole of H₂

Explanation:

The reaction expression is given as:

           2H₂O  →   2H₂  +   O₂

Given;

Number of moles of H₂O  = 2.54moles

Unknown:

Number of moles of H₂ produced  = ?

Solution:

To solve this problem, we use the concept of mole comparison. Now from the reaction expression, we know that;

                  2 mole of H₂O will produce 2 mole of H₂

                 2.54 mole of H₂O will then produce 2.54mole of H₂

Develop a relationship (in the form of a single sentence or equation) that can predict the charge based on the number and types of particle.

Answers

Answer:

The charge of an atom is determined by the ratio of protons to electrons

Explanation:

I hope this helps!!

A relationship showing the charge on an atom can be expressed as  ;

Types of particle are protons and electrons Charge on atom = ( Number of protons - Number of electrons )

The charge an atom posses depends on the particles/components of the atom which are protons and electrons. The protons are positively charged ions that are present in the nucleus of an atom while electrons are negatively charge ions present in the outer shell of an atom.  

To predict the charge on an atom we will determine the difference between the  number of protons and the number of electrons present in an atom.

Hence we can conclude that the relationship can be expressed as Types of particle are protons and electrons , Charge on atom = ( Number of protons - Number of electrons )

Impurities that evaporate easily and travel with the water vapor are not removed when using this type of distillation. Explain the reason for this.

Answers

Answer:

Please add as brainlist

Explanation:

Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.
