<u>Full Question:</u>
The list below includes some of the properties of butane, a common fuel. Identify the chemical properties in the list. Check all of the boxes that apply.
denser than water
burns readily in air
boiling point of –1.1°C
odorless
does not react with water
burns readily in air
does not react with water
<h3><u>
Explanation:</u></h3>
The type of alkane that is used in many products includes Butane. It is found as a natural gas in the environment. It is found on the deeper part of ground. It can be obtained by drilling process and gets used up in many of the products that is used for commercial purposes.
Molecular mass that is associated with butane is 58.12 g/mol. The boiling point of butane is -1 degree Celsius and -140 degree Celsius is its melting point. It is a liquefied gas and does not react with water. It will burn in air more readily.
<h3>
Answer:</h3>
1.265 g/mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of a rock as 43 g
- Volume of the rock as 34 mL
- Altitude of the rock as 4390 ft
We are required to calculate the density of the rock.
Density is the mass of an object per unit volume.
It is calculated by;
Density = Mass / volume
Therefore;
Density = 43 g ÷ 34 mL
= 1.265 g/mL
Thus, the density of the rock is 1.265 g/mL
Answer:
Sodium
Explanation:
Sodium is a pure chemical, hence it can be represented by the single chemical symbol Na.
Water has a chemical symbol of H2O, consisting of two, and not one, symbols, H and O.
Sulfate ion consists of a sulfide ion and four oxygen ions (SO4)2-. Hence, it does not fit.
Finally, potassium chloride has a chemical symbol of KCl. Consisting of two different chemical symbols, (K and Cl), it does not fit either.
Hope this helped!
Answer:
true
Explanation:
POPs bio-magnify throughout the food chain and bio-accumulate in organisms.
Answer:
Explanation:
The difference is in the amount of heat required to increase their temperature by 1 °C
It takes 4.19 joules to increase the temperature of water by 1 °C compared to Aluminium which is 0.900 joules to raise the temperature by 1 °C. Consequently, Aluminum will cool easily compare to water which will retain some of it heat longer because it does not heat up quickly like Aluminum.
