Japan! :D is the correct answer :)
Cap and trade reduces emissions, such as those from power plants, by setting a limit on pollution and creating a market. ... It's a system designed to reduce pollution in our atmosphere. The cap on greenhouse gas emissions that drive global warming is a firm limit on pollution. The cap gets stricter over time.
Answer:
All answers are correct. The Global Reporting Initiative is a framework that sets out the principles and indicators for organizations to measure and report their economic, environmental, and social performance; It’s an initiative to lead multinational enterprises to report globally; and it’s a framework to help national firms to report globally to gain international investors.
The Global Reporting Initiative is a global organization, which aims to set reporting standards for companies, regarding sustainable development.
The innovative character of GRI is based on three principles. First, the standards are developed collaboratively, through the cooperation of a diverse range of actors, who normally would not have considered themselves members of the same network. Second, GRI is designed as a self-regenerating system, a design that is designed to ensure adaptability. Finally, the system is based on an organizational structure that acts as guarantor of the standards, that are designed as a public good.
Answer: composition in weight percent = 41.25% Cu and 58.75% Zn
Composition in Atom percent = 40.54% Cu and 59.46% Zn
Explanation:
Starting with the composition in weight percent.
Let Mcu= mass of cu and Mzn= mass of zn
%W= weight percent
%Wcu = (Mcu/(Mcu + Mzn)) × 100%
By substituting the values
%Wcu = (33/(33+47)) × 100%
%Wcu = (33/80) × 100%
%Wcu = 41.25%
%Wzn = (Mzn/(Mcu + Mzn)) × 100%
= 47/80 × 100%
%Wzn = 58.75%
Then we can proceed to composition in atom percent
Atomic mass of Cu= Ac = 63.5g/mol
For zn = Az = 65.4g/mol
Atom percent cu = {(%Wcu×Ac)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
Substituting the values
= {2619.375/6461.625}×100%
=40.54% Cu
Atom percent zn = {(%Wzn×Az)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
={3842.25/6461.625}×100%
=59.46% Zn
