Nostrana [21]3 years ago
7 0

Answer:

Natural gas

Explanation:

Natural gas is a gaseous fossil fuel produced from organic matter that is used to heat homes and cook food.

Natural gas is one of the most volatile part of hydrocarbons that exist together with fossil fuel.

  • In a reservoir, natural gas is usually on top of the fossil fuel reserve.
  • It can also be distilled from crude oil as they rises up on top of the column first due to their low boiling point
  • The gas mixture is made up light hydrocarbons from methane to hexane.

Calculate the amount of carbon dioxid gas in 1.505x10^23 molecules of the gas.
Daniel [21]

Explanation:

  • We need to find the amount of carbon dioxide gas in 1.505\times 10^{23} molecules of the gas.
  • We know that, 1 mole weighs 44 gram of carbon dioxide which contains 6.022\times 10^{23} number of molecules. It means that, 6.022\times 10^{23} number of molecules present in 44 grams of carbon dioxide molecule. So,1.505\times 10^{23}  number of molecules present in :

=\dfrac{1.0505\times 10^{23}}{6.022\times 10^{23}}\times 44\\\\=7.675\ \text{grams}

  • Hence, 7.675 grams of carbon dioxide is present in 1.505\times 10^{23} molecules of the gas.

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to ? psi, the temperature changes from 110 degre
natta225 [31]
Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

I’m learning about heredity
Morgarella [4.7K]

Answer:

1. (See explanation)

2. 46. 23 from the mother’s egg and 23 from the father’s sperm.

Explanation:

ok for number one I am not entirely sure, but I am pretty sure that light, chemicals and temperature can all affect which genes get turned on and off. I am not entirely sure if the question is asking about the environment influencing inherited traits in the form of natural selection tho? If that is something you’re seeing right now, it might be a possible answer. But honestly I am not completely sure.

How do chemical and nuclear reactions differ in(c) Effect on rate of higher reactant concentration?
DochEvi [55]

Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.

<h3>What affects the rate of nuclear reactions?</h3>

Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

<h3>What is the main difference between chemical reactions and nuclear reactions?</h3>

Chemical reaction normally occurs outside the nucleus. Nuclear reaction happens only inside the nucleus. When chemical reactions occur elements hold their identity and the nuclei of atoms also remains unchanged. During nuclear reactions, the nuclei of atoms changes completely and new elements are formed.
