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:

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:

Metallic structure

Explanation:

They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.

[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]

Answer: Exothermic.

Explanation:

Exo means “outside” and the outside relates to surroundings so it’s my best choice.

Answer:

endothermic is the 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.

3 different elements are present in the compound.

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:

I hope this helps.

Answer:

Physical change is the same substance, while a chemical change is a new substance.

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)

Answer:

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.

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 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.

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.
