What is an advantage of using natural gas rather than a coal burning power plant?
Olenka [21]

Answer:

I hope it helps u

Explanation:

The advantages of using natural gas rather than coal are the following,

  • Natural gas is present in large amount than coal.
  • Natural gas is less costly than other fossil fuel sources of energy.
  • It increases security by decreasing dependence.
  • Natural gas is more environmentally friendly.
  • Natural gas is much safer to store.
  • It is reliable.
  • Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
  • Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.

How many of each element are present in this compound 4C4HgCL​
frozen [14]

Answer:

Percent Composition of Compounds

The percent composition (by mass) of a compound can be calculated by dividing the mass of each element by the total mass of the compound.

LEARNING OBJECTIVES

Translate between a molecular formula of a compound and its percent composition by mass

  • The atomic composition of chemical compounds can be described in a variety of ways, including molecular formulas and percent composition.
  • The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound.
  • The percent composition of a compound can be measured experimentally, and these values can be used to determine the empirical formula of a compound.

  • percent by mass: The fraction, by weight, of one element of a compound.
  • The atomic composition of chemical compounds can be described using a variety of notations including molecular, empirical, and structural formulas. Another convenient way to describe atomic composition is to examine the percent composition of a compound by mass.

  • Percent Composition by Mass

Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.
