Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

$NH_4^++NO_2^-\rightarrow N_2+2H_2O$

$Rate=k[NH_4^+]^x[NO_2^-]^y$

k= rate constant

x = order with respect to $NH_4^+$

y = order with respect to A $NO_2^-$

n = x+y = Total order

From trial 1: $3.2\times 10^{-3}=k[0.0100]^x[0.200]^y$ (1)

From trial 2: $6.4\times 10^{-3}=k[0.0200]^x[0.200]^y$ (2)

Dividing 2 by 1 : $\frac{6.4\times 10^{-3}}{3.2\times 10^{-3}}=\frac{k[0.0100]^x[0.2000]^y}{k[0.0200]^x[0.200]^y}$

$2=2^x,2^1=2^x$ therefore x= 1

Thus order with respect to $NH_4^+$ is 1.

how does getting funding from the government affect scientific research?? a- the government helps the scientist decide what rese

sertanlavr [38]

Answer:

d- Scientists have to follow government rules made to protect people.

Explanation:

Scientific research fosters our understanding of the world around us. It helps people to learn to promote critical thought and problem-solving. Although there may not be an immediate practical use of the research, in the long term the study could benefit humanity. Scientific research is the product of creative ideas and collaborative communication that the proper role of government is often restricted to funding the research. The role of the government is to perform its reasonable and valid duties of defending human rights and enhancing the independence of the human.

Here you go! 50% of your writing piece

Explanation:

Foods produced from or using GM organisms are often referred to as GM foods.

GM foods are developed and marketed because there is some advantage either to the producer or consumer of these GM foods. GM seed developers wanted their products to be accepted by producers and have concentrated on innovations that bring direct benefit to farmers and generally the food industry.

One objective for developing plants based on GM organisms is to improve crop protection. The GM crops currently on the market are mainly aimed at an increased level of crop protection through the introduction of resistance against plant diseases caused by insects or viruses or through increased tolerance towards herbicides.

Resistance against insects is achieved by incorporating into the food plant the gene for toxin production from the bacterium Bacillus thuringiensis. GM crops that inherently produce this toxin have been shown to require lower quantities of insecticides in specific situations, where pest pressure is high.
