Answer:
METAL: found in periodic table, lithium, shiny, lose electrons easily, good conductor, elements
NONMETAL: brittle, ductile, semimetals, found in periodic table, often gain electrons, semiconductors, carbon, shiny, poor conductor, elements
METALLOID: solid, non- ductile, malleable, found in periodic table, silicon, shiny, can be liquids, elements
An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect. From 1990 to 2015, the total warming effect from greenhouse gases added by humans to the Earth's atmosphere increased by 37 percent.
Answer: 1.4 moles
Explanation:
I can only assume you are looking for the amount of moles in 0.4M. the capital M means Molarity.
Molarity=moles of solute/liters of solution
Since we know the molarity is 0.4, we can plug this into our equation
moles= 1.4
