Answer:
gold i believe or possibly bromine
Explanation:
q- how does fluorine react with gold
a- this fluoride compound features gold in its highest known oxidation state. this red solid dissolves in hydrogen fluoride, but these solutions decompose, liberating fluorine.
q- how does chlorine react with gold
a- gold does react with halogens. it'll, for example, react very slowly with chlorine gas at room temperature to form gold chloride, AuCl3. if gold chloride is heated gently, it will decompose to release the pure elements again.
q- how does bromine react with gold
a- gold in bromine solutions dissolves according to electrochemical/chemical (EC) mechanisms. ... in the chemical composition of the mechanism, this monovalent gold bromide disproportionate into gold and stable AuBr −4 , which reports into solution. with respect to pH, there are two characteristic dissolution regions.

Fluorine will be most reactive with gold.
What is fluorine?
Of almost all of the elements, fluorine seems to be the most electronegative as well as reactive. Fluorine would be a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen would that be. It produces oxygen and even the incredibly corrosive hydrofluoric acid when it combines strongly with water.
What is reactive?Reactivity would be a substance's capacity to chemically combine with several other substances. Iron, for instance, reacts vigorously with oxygen.
As you move down the group, the halogens, which are non-metal elements in Group 7, become less reactive. In contrast to the alkali metals within Group 1 of the particular periodic table, this trend is the opposite. One of the most reactive elements in Group 7 was fluorine.

Europe and United States use geothermal power extensively.
True
False
Answer:
True
Explanation:
US. With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

Can carbon and hydrogen form double bonds between them?
Answer:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

A 4.00g sample of helium has a volume of 24.4L at a temperature of 25.0 C and a pressure of 1.00 atm. The volume of the helium is reduced to 10.4L, but the temperature and pressure of the gas are kept constant. What is the new quantity of the gas in moles
Answer:
0.852 mol
Explanation:
First we convert 4.00 g of helium (He) into moles, using its molar mass:
4.00 g ÷ 2 g/mol = 2 mol He
To answer this problem we can use Avogadro's law, which states that at constant pressure and temperature:
V₁n₂=V₂n₁
Where:
V₁ = 24. 4 Ln₂ = ?V₂ = 10.4 Ln₁ = 2 molWe input the data:
24.4 L * n₂ = 10.4 L * 2 molAnd solve for n₂:
n₂ = 0.852 molCan someone please please help me please
