What is the correct name for the following compound? "Make sure you are using correct naming
rules"

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.

answer

The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to about 417 parts per million in the last 151 years. The panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50-plus years.

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.

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  ;

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 )

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.

Answer:

When sleeping the energy exhibited is Potential energy. When I wake up and I’m preparing for the day I use kinetic energy which is the energy exhibited during motion.

Eating before leaving the house means I used chemical energy for replenishment of nutrients to aid the performance of more activities for the day. The food eaten and the physical activities also give rise to thermal energy which is why we sweat.

Answer:

Aluminum(2)sulfur(3)

Explanation:

Answer: 2

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles[/tex]

[tex]3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)[/tex]  

According to stoichiometry :

1 mole of [tex]Fe_3O_4[/tex] are produced by = 4 moles of [tex]H_2O[/tex]

Thus 1.18 moles of [tex]Fe_3O_4[/tex] will be produced by=[tex]\frac{4}{1}\times 1.18=4.72moles[/tex]  of [tex]H_2O[/tex]

Mass of [tex]H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g[/tex]

Thus 85.0  g of [tex]H_2O[/tex] will be required and 2 steps are required to get the answer.

Answer:

PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.

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.

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
