Choose the names of the substances for reactants of the equation
2H2 + O2—— 2H2O

Answers

the reactants are hydrogen and oxygen NOT water, WATER is the product

The names of the substances for the reactants in the chemical equation 2H₂ + O₂ → 2H₂O are; Hydrogen gas (H₂) and Oxygen gas (O₂). Option A and C is correct.

Hydrogen gas (H₂) - This is the molecular form of hydrogen, consisting of two hydrogen atoms bonded together.

Oxygen gas (O₂) - This is the molecular form of oxygen, consisting of two oxygen atoms bonded together.

In a chemical equation, the reactants are the substances that undergo a chemical reaction to form new products. In this case, the reactants are hydrogen gas (H₂) and oxygen gas (O₂). The arrow (→) in the equation represents the direction of the reaction, indicating that hydrogen gas and oxygen gas react to form water (H₂O).

The coefficient 2 in front of H₂ and H₂O indicates that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The balanced chemical equation shows the stoichiometry of the reaction, indicating the number of molecules of each reactant and product involved in the reaction.

Hence, A. C. is the correct option.

if 10.5 grams of liquid water is boiled how many grams of water vapor will then form ?

Answers

Answer:

It depends

Explanation:

This could vary depending on the exact temp, time and minerals. something with alot of salt boils quicker than something without it, so 10.5 grams?

The particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

What are minerals?

Minerals are defined as a naturally crystallized element or chemical compound that was created through geological processes. Natural materials are those that form on their own, such as minerals. Minerals don't droop, melt, or evaporate since they are solids. In contrast to the carbon compounds found in living organisms, minerals are inorganic. Minerals are crystalline: They have a unique atomic composition and arrangement.

Temperature is defined as a measure of hotness or coldness expressed in terms of any number of arbitrary scales that shows the direction that heat energy will naturally flow, i.e., from a hotter body to a colder body. The three temperature scales that are now in use are Kelvin, Celsius, and Fahrenheit. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature.

Thus, the particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

The city council of a small town wanted to add fluoride to their water so that all the residents would have healthier teeth. The mayor had read that ionic compounds must be used to get the fluoride into water. He looked up fluorine-containing compounds and came up with the following list. ​
NaF NF3 SiF4 CaF2 NH4F​

Using academic vocabulary in paragraph form, discuss the following: ​

Explain which compound(s) could produce fluoride ions in the water. In your response, be sure to include: ​
° which of the listed compounds are ionic and which are covalent. ​
° how ionic and covalent compounds are different. ​
° why only ionic compounds would produce fluoride in water.​

Answers

Answer:NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and  NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.

The compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

The ionic compounds are formed by the transfer of electrons between the atoms of the compounds. The ionic bonds are weaker and are easy to dissociate in the aqueous solution.

The covalent compounds are formed by the sharing of electrons between the atoms. Since there is sharing, there has been a strong bond, that has been hard to dissociate.

The Mayor has to release Fluoride in the water, thus ionic compounds are preferred that have the easy release of fluorine.

From the given compounds:

NaF = Ionic compound[tex]\rm NF_3[/tex] = Covalent compound[tex]\rm SiF_4[/tex] = Ionic compound[tex]\rm CaF_2[/tex] =  Ionic compound[tex]\rm NH_4F[/tex] =  Ionic compound

Thus the compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

How would you gather data to in order to determine the density of a marble

Answers

The average mass of a marble can be determined by dividing the total mass of the marbles by the total number of marbles: average mass of a marble.

To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.

Use the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).

To determine the density of a marble, we must know its mass and volume.

In order to determine the density of any substance we need to know its mass and volume.

Let's understand "Density".

The density of a substance is its mass per unit volume. It is represented with "ρ" this symbol.It can be given by the formula which is shown below: ρ= [tex]\frac{m}{V}[/tex] where m is the mass of the substance and V is the volume.Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure.

My parents had cautioned me so many times about wandering off and how easy it is to get disoriented. But, I wasn't planning to go very far. In fact, I kept looking back to make sure I could retrace my steps. Looking back didn't work. All of the trees began to look the same, and nothing looked familiar. It wasn't until I finally decided to make my way back that I realized I was lost! I had gone much farther, and for much longer, than I had planned.The warmth that the sun had brought to the forest in the daytime was now quickly disappearing. My parents' warnings came racing through my head. What did they tell me to do if ever I got lost? Over and over they drilled into me, "The most important thing to remember is S.T.O.P.!" It's an acronym for sit, think, observe, and plan. I stopped, sat down on the forest floor, and pulled my knees in close. It was cooling off, and a light drizzle was dampening the forest. I was lonely and scared. I knew that to survive, I had to stay warm, and I needed to drink water. Before I got any wetter, I made a very crude lean-to from the nearby branches and foliage. I managed to collect a bunch of dry leaves for a mattress. It was dark now. I took off my T-shirt and wrapped it around my legs, pulled on my hoodie, and curled up on the bed of leaves. I couldn't sleep. It was a cold, dark, and spooky night, and I was hungry.It felt like forever before the dawn filtered through the trees the next day. I knew I had to remain calm and make my whereabouts known. My family would be searching for me. I pulled out the only tool I had brought with me, my voice! I began to yell as loudly as I could,"Help!

I'm disappointed that you wandered off. I'm glad you told us where you were going, and I'm proud of you for remembering the survival techniques.

Captain Henry was directing all of his strength to hold the steering wheel and control the ship. The waves were the size of mammoths, and the boat continued to fill with angry water. Captain Henry yelled at his fellow sailors to scoop out the water that was weighing down the ship, but the sailors could not work any faster. "We are sinking! We are sinking!" shouted the sailors.Captain Henry knew that they were in trouble. With little time to spare before the ship began to sink into Lake Superior, Captain Henry made an urgent call to his older brother. His older brother had helped him with everything from cuts to broken bones all of his life. He was a father figure to Captain Henry. Coincidently, his older brother was also the strongest, bravest, and most dedicated coastguard in Bayfield, Wisconsin. Luckily, with Lake Superior just north of Bayfield, Captain Henry's brother would hopefully be able to rescue them soon. Captain Henry began to desperately flash the emergency lights on the boat so that his brother could find him. In the distance, the sailors pointed to a boat coming their way and tooting its horn. As Captain Henry's brother arrived, he threw a rope to the sailors and pulled them to safety. Standing on the boat, wrapped in blankets, the sailors, Captain Henry, and his brother watched the ship sink. "All good things must come to an end," stated Captain Henry, sadly. "But, hey!
