Explanation:

organic food is farmed and manufactured per the guidelines put forth by the Department of Agriculture. Organic food is typically pesticide-free, GMO-free, and sustainably farmed.

Non-GMO food, or non-genetically modified food, has not been altered or engineered in any way. Non-GMO food doesn’t necessarily adhere to the same guidelines that organic food does.

GMO food has been genetically modified in some form, usually in a laboratory.

Answer:

1) H - hydrogen - 1.100797

2) HE - helium - 4.00260

3) LI - lithum -6.941

Explanation:

On the periodic table the mass of carbon is reported as 12.01 amu. This is the average atomic mass of carbon. No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu.

Answer:

Skittles are coated with sugar and food coloring. When you add warm water to the Skittles, the sugar and food coloring start to dissolve. They have similar amounts coated on them so they dissolve at similar speeds and stay in their lanes.

The sugar is moving to areas of water with lower sugar concentration. If the water is poured in the center, this is happening for each Skittle at relatively the same speed.

The bond angle obtained based on the geometry of the molecule alone is known as the predicted bond angle.

When a compound is formed, the less electronegative atom in the compound is called the central atom in the molecule. The angle formed by the nuclei of two surrounding atoms with the nucleus of the central atom in a structure is called a bond angle.

The bond angle is usually based on the geometry of the molecule. The expected geometry can be deviated for certain reasons such as the presence of lone pairs on the central atom in the molecule. The bond angle obtained based on the geometry of the molecule alone is known as the predicted bond angle.

Answer: B

Explanation:

I. Rusting is a chemical reaction which is oxidation of iron.

II. Boiling water is a physical change. There is no chemical change between H2O molecules. It only shifts to the gas state from the liquid state.

III. When egg is cooked proteins are denaturated so it changes interactions between molecules.

IV. Melting is also just a phase change like boiling.

Answer:

atomic weight or number of neutrons.

Explanation:

An isotope: is one of two or more forms of the same chemical element.

Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number.

A different number of neutrons giving each elemental isotope a different atomic weight.

Answer:

I think the answer is A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

Explanation:

Here the nuclear decay of phosphorous to give S-32 is an example of beta-decay. Hence, the emitted particle is an electron. Thus, option b is correct.

The heavy unstable radioactive isotopes undergo nuclear decay by the emission of alpha or beta particle. Thus, there are mostly two types of decays, alpha decay and beta decay.

In alpha decay, the isotope emits a helium nuclei. Hence, mass number decreases by 4 units and atomic number decreases by 2 units. In beta decay, mass number does not change but atomic number increases by 1.

Here, P-32 undergo beta -decay by emitting an electron to form S -32. Hence, atomic number is increased by one. Therefore, the mission product is an electron option b.

I think 1, 4, and 5 are the answers to this question. I am not sure about 4 though.

Explanation:

You have to have a power source (1), you also have to have a way to get that power somewhere else (5), and the reason for 4 would be that the power has to come back through the power source to remain working.

D: a heterogeneous mixture with components of varying sizes

Heterogeneous mixture is a combination of substances that doesn't have uniform composition and properties. Just by looking at the mixture you can differentiate the compounds because they are so different. Using a sieve, allows the components with different sizes to separate, while one is retained, the others can pass the holes in the sieve.

You can simply subtract the atomic number from the mass number in order to find the number of neutrons.

Answer:

There are four natural states of matter: Solids, liquids, gases and plasma. ... Solids have a definite shape, as well as mass and volume, and do not conform to the shape of the container in which they are placed. Solids also have a high density, meaning that the particles are tightly packed together.

In which one element replaces a similar element in a compound?

A single-replacement reaction

A single-replacement reaction is a reaction in which one element of a compound is replaced by another.

Answer:

34.9103 or 34.9 g

Explanation:

Remember Density is a broken heart: m/v.

In this scenario (Let x = # of grams in the sample of gasoline),

D = 0.7198 g/mL = x g / 48.5 mL

So,

(0.7198 g/mL) * (48.5 mL) = x g

x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
