Answer:

The rate would be higher, and the concentration of products would be lower.

Explanation:

The correct answer is The rate would be lower, and the concentration of products would be higher.

The rate of reaction refers to the speed with which reactants are converted into products.

The rate of reaction decreases as the reaction progresses because more reactants are being converted into products.

As such, the reactant concentration decreases and the concentration of products increases.

Hence, after three seconds, the rate would be lower, and the concentration of products would be higher.

From a chemicals standpoint, Student 2 contends that as global population grows, so does the need for water. This is the correct reasoning.

What is the purpose of chemistry?

Our basic needs of food, clothes, shelter, health, energy, and pure air, water, and soil are all met by chemistry. Chemical technologies improve our quality of life in many ways by offering fresh approaches to issues with health, resources, and energy use.

What subjects are studied in chemistry?

The study of matter, including its properties, behaviours, and structures, is known as chemistry. Chemists induce and monitor these reactions both in nature and artificially in a lab setting because they are interested in how materials behave and react in specific settings.

Answer:

Light Photons: Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more.

Infrared photons: Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.

On the electromagnetic spectrum, visible light has a wavelength that falls between 380 nm and 750 nm, whereas infrared light, which marks the beginning of the non-visible spectrum, has a wavelength that falls between 700 nm and 1 mm. Because of this, infrared can only be viewed with specialized tools like security cameras.

A type of radiant energy that we experience as heat, but that is invisible to human eyes is infrared radiation (IR), often known as infrared light. The sun and fire are two of the most prominent sources of IR radiation, however all objects in the cosmos release some of it.

The energy of the photons determines the various types of radiation, starting with radio waves with low energies. In comparison to visible, ultraviolet, X-ray, and gamma ray photons, which are the most energetic of all, microwave photons have somewhat higher energy. Infrared photons have even more energy.

Cooler objects produce lower energy, longer wavelength photons, while hotter ones release higher energy, shorter wavelength photons.

Thus, On the electromagnetic spectrum, visible light has a wavelength that falls between 380 nm and 750 nm, whereas infrared light.

Explanation:

Answer:

1. increase the temperature

2. increase the concentration of reactants

3. increase the surface area of the reactants

4. use a catalyst

5. remove the product as it's formed

Explanation:

for a chemical reaction to take place, the bonds between atoms in the reactants are broken, the atoms rearrange and new bonds between the atoms are formed to make the products.

Explanation:

What has changed in the atmosphere is that oxidation has occurred where an oxidizing chemical specie has reacted with an oxygen containing compound.

Now these chemicals when they react with rain and fall on rocks react with the rocks to weaken them in a process known as chemical weathering.

Now when this weathering from the oxidizing chemicals from the rain react with rocks that contain iron, it leads to the rock having an appearance of rust.

Explanation:

In this question ,I am going to assume that the acid is monoprotic acid(contains only one hydrogen) which I'll represent by HA.

Chemical equation:

NaOH(aq) + HA(aq)----->NaA(aq) + H2O(l)

The mole ratio of NaOH:HA is 1:1

1.25M NaOH=1.25 Moles/L or 1.25 moles /1000ml of NaOH

(1.25 moles /1000ml) x (24.65ml)=0.0308125 moles NaOH

Mole ratio is 1:1

So, moles of HA are also 0.0308125 moles

volume of HA  =15ml

To find molarity of HA:

=(0.0308125 moles x 1000ml)/(15ml)

~2.054M of HA

Sun and the stars, nothing humans don't use fusion at all

Explanation:

Nuclear fusion reactions  power the  sun  in space. Humans currently use fusion in nuclear weapons by means of nuclear reactions, but researchers are seeking more applications.

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:

[OH-] = 1.8 x 10^-7

Explanation:

pH + pOH = 14 --> 6.93 + pOH = 14 *subtract 6.93 from both sides

pOH = 7.07

-->

10^pH => 10^-6.93 => 1e - 6.93 [H+]

-->

H+ x OH- = 1 x 10^-6.93 *divide H+ from both sides

-->

[OH-] = 1.17 x 10^-7 or 1.8 x 10^-7

Mass of the liquid water in the container is 35 grams-

The mass of the liquid water in the container should be 35 grams.

Mass would not change during a change of state because the number of particles does not change during a state change. It does not matter if a substances freezes, boils, melts, sublimates.

So, the mass of liquid water in the container is the same as ice. Hence, the correct option is (A).

Answer:

A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection.
