How are elements and compounds similar

2 answers:

6 0

I don't like to just give people the answer...so I'll explain what they are as well as differences and you should be able to deduce how they are similar. Compounds are basically a mix of atoms from different elements. An Element is a pure substance made up of one type of atom (you find them on the periodic table). Compounds can be broken down into similar forms...elements cannot. Compounds list is basically endless...so far there are only about 117 known elements. Compounds are expressed as a formula...Elements are expressed using symbols. Hope this helps get you on the right track!

Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl)

1.40 m3 is how many mL

Zarrin [17]

$\LARGE{ \boxed{ \rm{ \pink{Solution:}}}}$

We know, 1 m³ of space can hold 1000 l of the substance.

⇛ 1 m³ = 1000 l----(1)

And, 1 l is 1000 times more than 1 ml

⇛ 1 l = 1000 ml------(2)

So, From (1) and (2),

⇛ 1 m³ = 1000 × 1000 ml

⇛ 1m³ = 1000000 ml

We had to find,

⇛ 1.40 m³ = 1.40 × 1000000 ml

⇛ 1.40 m³ = 140/100 × 1000000 ml

⇛ 1.40 m³ = 1400000 ml

⇛ 1.40 m³ = 14,00,000 ml / 14 × 10⁵ ml / 1.4 × 10⁶ ml

☃️ So, 1.40 m³ = 14 × 10⁵ ml / 1.4 × 10⁶ ml.

How does a thermometer work

andrew11 [14]

This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Mercury is very reactive and works best. But mercury is also very a radioactive element. So, if you break the thermometer, you could get in trouble (radio active posoning) Alcohol work well, it is not radioactive and can't kill you.
Okay, hope I helped
