Answer:
Control group
Explanation:
In an experiment, the group which receives the treatment (in this case injection of actual drug) is known as experimental group because the experiment is being conducted on it. While on the other hand the group which do not receive the treatment is known as control group. The results obtained from the experimental group are compared with the control group to determine the effectiveness of the treatment.
Answer:
Explanation:
The nitrogen cycle is an important cycle to the atmosphere. Nitrogen is an essential part of biological molecules such as proteins and nucleic acid, which makes nitrogen essential for all living organisms. Nitrogen makes up 78 percent of the atmosphere.
<span>It is linear, because using the VSEPR theory, when you draw its lewis structure, you get two bonded pairs of electrons, which signifies a linear structure.</span>
metals (left side of periodic table) become positive ions so calcium would be the answer
The part of the chemical equation is incorrect is The solution is 10 02, it ought to de 1302.For carbon, on each aspects, there are eight carbon atoms.For hydrogen, on each aspects there are 20 hydrogen atoms.
<h3>What a part of a chemical equation are you able to by no means alternate?</h3>
When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.
The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.
- To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.
- For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.
