Fluorine + sodium chloride → sodium fluoride + __________. What is the missing chemical name?
Answer:
Chlorine (Cl)
Explanation:
The equation would be:
[tex]F+NaCl[/tex] → [tex]NaF + Cl[/tex]
This is because no atom is lost in a reaction. Chlorine would be the missing chemical as it is on the other side of the equation and needs to be accounted for on the products side.
The missing chemical in the reaction of sodium chloride with fluorine forming sodium fluoride is chlorine.
What is a chemical equation?The chemical equation is given as the representation of the reactants molecules and the product molecules in a chemical reaction.
The reaction follows the law of conservation and thereby no element will be lost in the reaction. Thus, the chemical reaction for the fluorine and sodium chloride is given as:
Fluorine + Sodium chloride → Sodium fluoride + Chlorine
Thus, the missing chemical in the reaction was chlorine.

Find the mass of iron that has volume of 111 ml.
Answer:8
842.46 or to the next whole number
Explanation:
just multiply the mass of iron with the volume mL you have.
The mass of the iron whose volume and density are 111 ml and 7.847 g/cm³ respectively is 871.01 grams.
Which term is equivalent to product of density and volume?
The product of density and volume of a substance represents its mass. Mathematically -
M = V x ρ
where -
ρ - density
M - mass
V - volume
Given is iron in liquid form. It occupies a total volume of 111 ml.
The mass of liquid iron can be calculated using -
M = V x ρ
Volume of iron [V] = 111 ml = 111 cm³.
Density of iron [ρ] = 7.847 g/cm³
Therefore, we can write -
M = 7.847 x 111
M = 871.01 grams
Therefore, the mass of the iron whose volume and density are 111 ml and 7.847 g/cm³ respectively is 871.01 grams.

describe in your own words the structure of solid sodium chloride and explain why it is formula is NACL
Answer:
Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond. By the way, chloride is the term used to designate the anion form of chlorine. The result is a crystallized salt that has properties that are different from the two parent elements (sodium and chlorine). The chemical formula for sodium chloride is NaCl, which means that for every sodium atom present, there is exactly one chloride atom.

Answer:
In fact, the moon is one of the least reflective objects in the solar system. The DSCOVER spacecraft captured this single photograph of the moon and the earth. Both the earth and the moon are illuminated by the same amount of sunlight coming from the same angle in this photo.
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
Allison adds ice cubes to water which is at room temperature. Over time, the ice melts.
Read the statement above. How does adding ice to the room temperature liquid change the average kinetic energy of the particles of the
liquid?
Adding ice to the liquid decreases the average kinetic energy of the particles of the liquid.
The temperature of a substance is defined as a measure of the average kinetic energy of the molecules of the substance. The average kinetic energy of the molecules of a substance is directly proportional to the temperature of the substance.
This implies that if I increase the temperature of a substance, the average kinetic energy of the molecules of the substance increases and vice versa.
Ice is at a lower temperature than water at room temperature. Thus, adding ice to water at room temperature decreases the temperature of the water and consequently decreases the average kinetic energy of its particles.

How are glucose and galactose epimers?
Kindly describe in brief how this epimer is different from manose and glucose one.
Help please and thanks!
Answer:
hehe I needed some brianliest plz OK
Explanation:
Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.
Glucose and mannose are epimers that differ at the C-2 carbon, while glucose and galactose are epimers that differ at the C-4 carbon, as shown below. When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1.

Answer:
The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2).
Why do scientists create proxies?
Answer:
Proxies enable scientists to recreate climate conditions in different parts of history.
Explanation:
Proxies are characteristics of the weather in a certain period of time that have been preserved for different weather measurements like temperature, humidity, wind direction, and amounts of precipitation. The reason scientists create proxies because it "enables them to recreate climate conditions from different parts of time to have a better understanding on what weather was like during that time period."

Based on location in the periodic table, which element has chemical properties that are most similar to iodine
xenon (Xe)
calcium (Ca)
Selenium (Se)
fluorine (F)
Answer:fluorine
Explanation:
Based on location in the periodic table, fluorine (F) has chemical properties that are most similar to iodine.
In the periodic table, elements are classified in groups and periods. The elements in the same group are chemically similar and they have the same number of valence electrons. Elements in the same period have the same highest energy level.
Hence, when looking for an element that is most chemically similar to iodine, we have to consider the element that is in the same group with iodine.
Both fluorine are iodine are both in group 17 hence, fluorine is most chemically similar to iodine.

Answer:
I think that it would be better to have smaller cells because smaller cells takes less energy to transport waste and generally more efficient to control than larger cells. It is better to have smaller cells because larger and fewer cells takes up more nutrients, but doesn't cover as many surface area. In the end, smaller cells are more efficient, cover more surface area, and moves faster than bigger cells.

Greenhouse gases such as N2O, CO2 and CH4 absorb heat. However, CH4 absorbs more heat than CO2 hence its emission must be controlled.
Green house gases are gases that when released into the atmosphere, can absorb infrared radiation and prevent it from escaping into outer space. This causes the temperature of the earth to increase steadily. Lately, the concentration of the greenhouse gases in the atmosphere has increased owing to anthropogenic activities such as burning of fossil fuels.
Green house gases include; N2O, CO2, CH4 etc. However, CH4 is capable of absorbing even greater heat than CO2. This makes it even more imperative to control the emission of methane gas.
