What is the difference between a chemical formula and chemical equation?

A chemical formula is just one molecule. For example, the chemical formula for water is H2O. The chemical formula for ammonia is NH3

A chemical equation contains reactants and products, which are molecules or groups of molecules. For example, what is the chemical equation for the formation of water.

2H2 + O2 ---> 2H2O

What is the name of a twelve sides prism?

A twelve-sided prism is called a dodecagonal prism. The prefix "dodeca-" denotes twelve sides, while "gon" refers to a polygon. In geometry, a prism is a polyhedron with two parallel and congruent faces called bases, and its other faces are parallelograms. A dodecagonal prism would have twelve sides, twelve vertices, and twenty-four edges.

What is AgNO3 plus KCl equals AgCl plus KNO3?

It is a "double replacement" reaction between silver nitrate and potassium chloride, to yield silver chloride and potassium nitrate.

AgNO3+ KCl → AgCl + KNO3

What is b x b simplified?

Ah, when you have b multiplied by b, you are actually squaring b. So, b x b simplified is b^2. It's like painting a beautiful little square with sides of length b, isn't that just lovely?

How much is six dozen?

A dozen is 12, so six dozen is 6 x 12 = 72.

At $2.79 a dozen, it's $16.74 plus tax.

What is a gradient lens?

A gradient lens is tinted darker at the top and fades to clear at the bottom. It helps block out bright light from above while keeping the bottom clear for things like reading or using your phone. If you're looking for these lenses, Eyeglass Direct has a nice range of stylish options that are both practical and fashionable.

What is 10 to the negative 12th power?

10 to the negative 12th power is equal to 1 divided by 10 raised to the 12th power. This can be simplified to 1 divided by 1 followed by 12 zeros, or 0.000000000001. In scientific notation, this would be written as 1 x 10^-12.

How do you make 27 using 1 2 3 and 4 only once?

To make 27 using the numbers 1, 2, 3, and 4 only once, you can use the following mathematical expression: (3 * 4) + (2 * 1) = 12 + 2 + 1 = 27. This equation follows the order of operations (multiplication before addition) to correctly arrive at the desired result of 27.

What math equations equal number 63?

There are several math equations that equal 63. Some examples include: 9 x 7 = 63, 126 ÷ 2 = 63, and 63 = 63. These equations demonstrate different mathematical operations such as multiplication, division, and equality that result in the number 63.

What is the value of the digit 2 in 0.22?

Well, isn't that just a happy little question! The digit 2 in 0.22 is in the hundredths place. It's worth two tenths, which is a lovely little part of the whole number. Just remember, every digit has its own special place and value on the canvas of mathematics.

What are the positive and negative human impacts on a savanna?

Positive human impacts on a savanna may include sustainable agriculture practices that support local communities and biodiversity conservation efforts that protect the ecosystem. However, negative impacts can arise from deforestation for agricultural expansion, leading to habitat loss and fragmentation, as well as overgrazing by livestock, which can degrade the soil and reduce vegetation cover. It is crucial to balance human activities with the conservation of savanna ecosystems to ensure their long-term sustainability.

What is the sum of two consecutive even integers that equals to 60?

Let's denote the first even integer as x. The next consecutive even integer would be x + 2. Since they sum up to 60, we can write the equation x + (x + 2) = 60. Simplifying this equation gives us 2x + 2 = 60. Solving for x, we find x = 29. Therefore, the two consecutive even integers are 29 and 31, and their sum is 60.

IS 100000000000000000000000000000000000000000000000000 A NUMBER?

Yes. In fact, it would be impossible for it to not be a number, since you typed it. Indeed, any combination of numbers you ever type, will be "a number".

This one, though? It's called a sexdecillion.

What is the percent of prime numbers from 1-100?

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97 are the prime numbers in this range, and there are 25 of them. So, of the 100 numbers, 25 are pime, giving us 25%.

How many angles does an oval have?

Oh, dude, an oval has an infinite number of angles if you really think about it. But if you want to get technical, an oval technically has zero angles because it's a curved shape, not a polygon with straight sides. So, like, it's a trick question, man.
