Answer:

a) gold - Solid

b) gasoline - liquid

c) oxygen - gaseous

d) olive oil - liquid

e) mercury (found in thermometers) - liquid

f) aluminum - solid

Explanation:

Matter exists in three states viz: solid, gas and liquid. Note that, room temperature is a neither hot or cold temperature, which is about 20-23°C.

A) Gold is a transition metal with the symbol Au. At a room temperature, Gold, like most metals are found as SOLIDS.

B) Gasoline is a liquid mixture of refined hydrocarbons majorly used as fuels.

C) Oxygen is a chemical element with symbol O. It is a constituent of natural air, which is a mixture of different gases including oxygen. Hence, at room temperature, Oxygen is a gas.

D) Olive oil is a vegetable oil got from olives. It is composed of fats and it's a liquid at room temperature.

E) Mercury is an element with symbol Hg. It is the only metallic element found naturally (at room temperature) as a liquid. It is used in thermometers.

F) Aluminum is another chemical element with symbol Al. It is a lustrous metal that occurs as a Solid in room temperature.

Answer:

Particles exchange energy through elastic collisions.  

All particles are in constant random motion.

Except during collisions, interactions between particles are negligible.

Temperature depends only on the average kinetic energy of the particles.

Answer:

A,B,D,E egd

Explanation:

Atoms are the building block of science for starters meaning that all solid and liquid thing will contain atoms. Matter is anything that has mass and takes up space. So, in order to prove that air is matter, we need to prove that air has mass and takes up space. To prove that a bicycle has matter, you would  need to show that it has a weight and will take up space.

Answer:

Lactic acid is used to prepare medicine. It is colorless, can be solid or liquid form.

Explanation:

Acids are sour in taste. It changes the color and taste of the chemical. It reacts with some chemicals metals and produce the hydrogen. It react with hydrogen. I also react with the bases and produce the salt. It also promotes some of the chemical reaction. For example nitric acid, phosphoric acid sulfuric acid and the organic acids.

The lactic acid is soluble with ethanol and water. It is produced by the reaction of two strategies, the synthetic method and biotechnological methods. It is produced at very large scale by the help of fermentation. Lactic acid is colorless, in liquid or solid form. It is a weak acid and can react in the way as the stronger acids react.

Answer:

(D) is the correct option.

Explanation:

Molar mass of NO = (14+16) g/mol = 30 g/mol

Molar mass of NO₂ = (14+16×2) g/mol = 46 g/mol

Molar mass of N₂O = (14×2+16) g/mol = 44 g/mol

Molar mass of N₂O₅ = (14×2+16×5) g/mol = 108 g/mol

Number of moles = mass/molar mass

mass = n × M, M = molar mass

n = 1 mol in each case

Higher the molar mass, greater is the mass of the compound. The molar mass of N₂O₅ is greatest of all other cases. It will have greatest mass.

I'm really sorry but you shouldn't be asking anyone this question. I know chem is hard so you should put a little effort into the class. Save the money that you would be using to pay people and save it up as a big reward for passing chem class. Chemistry is valuable information that could help you in your future life. Please dont hate me for this. just trust me. If you put in the extra work then you will feel good about it when you pass the class. If the teacher find out that you cheated, it would probably go on your permanent record. Hope this helps

Answer:

D . oxidation and reduction oxidation

The light reactions synthesize ATP, NADPH, and oxygen using oxidation and reduction. Therefore, option D is correct.

The term oxidation is defined as the loss of electron and tha term reduction is defined as the gain of electron. When oxidation and reduction takes place simultaneously is called as redox reaction.

In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, the formation of O2 from H2O.

During the light reactions, water is oxidized, electrons are shifted from water to NADP+, and ATP is compounded. The three components of the light reaction can be resumed with equations: Oxidation of water. 2 H2O 02 + 4e- + 4 H.

Thus,The light reactions synthesize ATP, NADPH, and oxygen using  oxidation and reduction, option D is correct.

Answer:A

Explanation:

Move the decimal forward 3 times.

Answer:

True

Explanation:

This is true because every chemical reacts differently

your answer is 0.00833M the volume was converted into liters

NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)

Using the molarity equation, we can find the number of moles of HCl that reacted:

molarity=mol soluteL soln

mol solute=(molarity)(L soln)

mol HCl=(0.105molL)(0.0250L)=0.00263 mol HCl

(volume converted to liters)

Now, using the coefficients of the chemical reaction, we can determine the number of moles of NaOH that reacted:

0.00263mol HCl(1lmol NaOH1mol HCl)=0.00263 mol NaOH

Lastly, we'll use the molarity equation (using given volume of NaOH soln) again to determine the molarity of the sodium hydroxide solution:

molarity=mol soluteL soln

Answer:

It gains electrons, reducing its overall charge

Explanation:

When an element is reduced, It means It gains electrons, reducing its overall charge. Hence the correct option is (B)

Redox is a type of chemical reaction in which the oxidation states of substrate change.

Oxidation is the loss of electrons or an increase in the oxidation state (Charge) of a chemical or atoms within it.

Reduction is the gain of electrons or a decrease in the oxidation state (Charge) of a chemical or atoms within it.

Therefore, When an element is reduced, It means It gains electrons, reducing its overall charge. Hence the correct option is (B)

Answer: Butane and benzene are both compounds. They contain multiple elements bonded together in a specific ratio. Kerosene and gasoline are mixtures because they are combinations of several compounds. Oxygen is an element because it is made up of only one type of atom.

Explanation: im doin edge 2020

Butane and benzene both are compounds. Gasoline and kerosene both are mixture and oxygen are an element.

A substance can not be broken into simple components by any chemical reaction is called elements.

A substance is from a combination of two or more different chemical elements is called compound.

Butane (C4H10) and benzene(C6H6) are both compounds. They contain multiple elements like carbon and hydrogen bonded together in a certain ratio.

Kerosene is a combination of hydrocarbons and basically it is made up of aromatic hydrocarbon and gasoline is a mixture of hydrocarbons, additives and blending agent so kerosene and gasoline both are mixtures.

Oxygen is an element because it is made up of only one type of atom.
