Explanation:
Fossil fuel is an overall term for covered ignitable geologic stores of natural materials, framed from rotted plants and creatures that have been changed over to unrefined petroleum, coal, flammable gas, or weighty oils by introduction to warmth and weight in the world's outside more than a huge number of years.
The consuming of petroleum products by people is the biggest wellspring of emanations of carbon dioxide, which is one of the ozone depleting substances that permits radiative compelling and adds to an unnatural weather change.
A little bit of hydrocarbon-based powers are biofuels gotten from climatic carbon dioxide, and consequently don't build the net measure of carbon dioxide in the environment.
Answer:
by having positive and negative ends and stronger intermolecular forces of attraction.
Explanation:
hope this helps
plz mark brainiest
and im sorry if the answer is wrong
Explanation:
The given data is as follows.
Air is at and 14.6 psia.
= 0.00015 ft, Flow rate, (Q) = 48000
(a) Formula to calculate hydraulic radius is as follows.
=
= ft
Formula for equivalent diameter is as follows.
=
= ft
(b) Formula for velocity floe is as follows.
Q = VA
V =
= ft/min
= 24000 ft/min
(c) Formula to calculate Reynold's number is as follows.
=
= (as and = 0.0443 lb/ft. hr)
= 53742.66 hr/min
As 1 hr = 10 min. So,
= 3224559.6
(d) Formula to calculate pressure drop is as follows.
Putting the given values into the above formula as follows.
=
= 6.238
The symbols for three different cations with 14 protons are Si²⁺, Si⁴⁺, and Si³⁺.
An element with 14 protons must be <em>silicon, S</em>i.
Its electron configuration is [Ne] 3s²3p², so it could lose up to four valence electrons.
The most likely cations are Si²⁺, Si⁴⁺, and Si³⁺ (or Si⁺).
Answer:
6.022 × 10²³ molecules of B₂H₆
Explanation:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
B₂H₆ molecules:
21.63 g = one mole of B₂H₆= 6.022 × 10²³ molecules of B₂H₆
