Answer:
A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations
Answer:
197.07 K
Explanation:
To solve this problem we can <u>use the PV=nRT equation</u>, where:
- P = 205 kPa ⇒ 205 * 0.00986 = 2.02 atm
- V = 0.0120 m³ ⇒ 0.0120 * 1000 = 12 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
We<u> input the data</u>:
- 2.02 atm * 12 L = 1.50 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
12/12= 1 mol
this is because: amount of moles=mass/relative formula mass and the relative formula mass of carbon is 12
Ionic bonds is formed between metal and nonmetal with opposite charges. Metal have (+) charge and nonmetals often have (-) charge.
Choice (a) is wrong because both charges are the same.
Choice (c) is wrong b/c same changes.
Si and O do not have charges for now. (d) is wrong.
Choice (b) is correct. Opposite charges and the ionic compound is BaCl2
