Answer:

Petroleum, also called crude oil, is a fossil fuel.

petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria

Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use

Answer:

Aqua regia is a corrosive, fuming yellow solution that is a 1:3 mixture of concentrated nitric and hydrochloric acids.

Aqua regia is a mixture of hydrochloric acid (HCl) and nitric acid (HNO3) at a ratio of either 3:1 or 4:1. It is a reddish-orange or yellowish-orange fuming liquid. The term is a Latin phrase, meaning "king's water". The name reflects the ability of aqua regia to dissolve the noble metals gold, platinum, and palladium.

Explanation:

0.714g of Helium is contained in the balloon

STP stands for standard temperature and pressure. STP refers to a specific pressure and temperature used to report on the properties of matter.

According to IUPAC( International Union of Pure and Applied Chemistry), it is defined as -

It is generally needed to test and compare physical and chemical processes where temperature and pressure plays an important role as they keep on varying from one place to another.

One mole of a gas under STP conditions occupies a volume of 22.4L.

Given,

Volume = 4L

1 mole of a gas occupies 22.4L of volume at STP.

Thus, 1L of a gas occupies = 1 / 22.4 moles

so, 4 L will occupy = 4 / 22.4 moles

                               = 0.178 moles

Moles = mass / atomic mass

Mass =  moles × atomic mass of He

             = 0.178 × 4

              = 0.714g

Therefore, 0.714g of Helium is contained in the balloon.

Answer:

The sun, like all stars, is able to create energy because it is essentially a massive fusion reaction. Technically known as nuclear fusion, this process releases an incredible amount of energy in the form of light and heat.

Types of energy produced: Stars produce energy from nuclear reactions, primarily the fusion of hydrogen to form helium.

Answer:5 1/2. occurred the other day i think

Explanation:

Explanation:

the answer is D they both increase

When ethylene glycol (an antifreeze) is added to water, the boiling point of the water increases, and the freezing point decreases.

Antifreezers are the substance which on mixes with any other compound will decreases the freezing point of that compound.

When we add ethylene glycol which is an antifreeze substance in the water then depression in freezing point takes place but at the same time elevation in boiling point also happen, because they had a great attraction force within themselves.

Hence increasing in boiling point and decreasing in freezing point takes place.
