Hot spot volcano is the type of volcano which is formed at a weak spot in

the middle of a plate.

Hot spot volcano is an area in the Earth crust which is characterized by large

amount of heat flow in the area due to the volcanic activity. Hot spot  

volcano is formed at the middle of the plate as against junctures in which

other types are formed.

The weak spot is what gives rise to the unusual heat flow which makes hot

spot volcano most appropriate.

I think. Protons and electrons share the same number as well as the atomic number.

Answer:

31 protons

Explanation:

Protons are positively charged and electrons are negatively charged so if it is a neutrally charged atom (which most are) the protons and electrons will be equal.

Answer:

When the drill hits oil, some of the oil rises from the ground high into the air. This immediate release of oil is known as a "gusher." Once a reservoir has been located, pumps are used to extract the oil.

Answer: The products will be copper and oxygen.

Explanation: Copper electorde is an active electrode so it constantly takes part in the electrolysis. Cathode is a pure copper negative electrode and anode is a impure copper positive electrode. So the copper present in the solution, along with the copper present in the anode will come off and go to the cathode. As a result, cathode gains copper. And the remaining impurities settle down in the bottom.

In the anode, oxygen will be given off because according to the order of discharge, if SO4 is present then the ions will stay in the solution and oxygen will be released. So at the end, solution of SO4 and H2O will be remaining while copper and oxygen is extracted.

The half equations are-

Cathode: Cu2+ + 2e- = Cu

Anode: Cu + 2e- = Cu2+

Something you might not know: The solution in electrolysis turns blue when copper goes to the cathode. So copper electrodes are also used in electroplating.

The position where the moon is located where its shadow may sometimes reach Earth is position A .

We know that in the outer space there are a lot of celestial bodies that can be found. Now we know that a celestial body is one that can be found in the outer space and the moon and the sun are all parts of the celestial bodies that we can find in the solar system.

In this case we  are being asked for the position of the moon that could lead to an eclipse where the moon would come between the earth and the sun and that is the position A.

Answer:

Only chemical equation uses arrow instead of = sign

Answer:

Only chemical equation uses an arrow instead of a = sign.

A chemical equation depicts a chemical reaction by utilising chemical formulae and symbols to depict the reactants, products, and chemical changes that take place. In a chemical equation, the arrow indicates the direction of the reaction and is commonly depicted as a single arrow pointing from the reactants to the products. In contrast, the equals sign (=) is commonly used in mathematical equations to indicate that two expressions have the same value.

While numbers are used to indicate the relative proportions of reactants and products and minus signs are used to indicate reactants or products in the form of ions, the arrow is the most distinguishing feature that distinguishes chemical equations from mathematical equations.

The hydronium ion concentration of a solution with a pOH of 6.90 is 7.94 × 10⁻⁸ M.

Relation between the pH and pOH will be represented by the below equation as:

pH + pOH = 14

Given that pOH = 6.90

So, pH = 14 - 6.90 = 7.1

Also we know that, pH = -log[H⁺]

[H⁺] = [tex]10^{-pH}[/tex]

[H⁺] = [tex]10^{-7.1}[/tex]M

[H⁺] = 7.94 × 10⁻⁸ M

Hence the concentration of hydronium ion is [tex]10^{-7.1}[/tex] M.

Answer:

A pH calibration is the process of adjusting your pH meter by measuring solutions of a known pH value. This is because the characteristics of your electrode will change over time and this needs to be compensated for. A calibration does this by matching your pH meter to the current characteristics of your pH sensor.

Rainforests are important due to the amount of oxygen the tree's produce. It also adds biodiversity and more balance in the food chain of animals.

2.

If we slowed transportation and agricultural farming, greenhouse gases and carbon monoxide would be reduced magnificently.

3.

One way is that Humans are supplying demand for animal agriculture for food (when not need to). The greenhouse gases created by the factories alone are creating much of the ozone's destruction. Also, another reaction to demand of meat is, The space needed for farmland. They burn down much of the rainforest for farmland and grass for the cows and other animals. Thirdly, traveling alone and having many household luxuries aren't helping either. Lowering the use of composite resources and more wind, solar, and water energy can help the earth in total.

4.

Introducing invasive species endangers many of the other species. They could have a advantage or disadvantage over the other species. causing either over, or under, population for many of the species. Throwing the balance of it all off.
