igence and asked the assistants to assess the groups’ maze-solving abilities. The scientist had not actually sorted the mice by intelligence. The students rated the ""highest intelligence"" group of mice as the best maze solvers and the ""lowest intelligence"" group as the worst maze solvers. What was the scientist trying to demonstrate by doing this experiment?Experimental subjects should never be put into groups.Mice should not be judged by their intelligence.Higher intelligence mice are better maze solvers.People can introduce their own biases into an experiment.

Ammonia, NH3(g), can be used as a substitute for fossil fuels in some internal combustion
sammy [17]

Answer:

4 NH₃ (g) + 3 O₂ (g) ----> 2 N₂ (g) + 6 H₂O (g) + energy

Explanation:

The unbalanced equation:

NH₃ (g) + O₂ (g) ----> N₂ (g) + H₂O (g) + energy

<u>Reactants:</u> 1 nitrogen, 3 hydrogen, 2 oxygen

<u>Products:</u> 2 nitrogen, 2 hydrogen, 1 oxygen

The sort-of balanced equation

2 NH₃ (g) + 1/2 O₂ (g) ----> N₂ (g) + 3 H₂O (g) + energy

I first started by balancing the nitrogens. This then lead me to balance the hydrogens. When I went to balance the oxygens, only a 1/2 coefficient would work. However, 1/2 coefficients are technically incorrect. To get rid of this coefficient, you need to multiply each coefficient by 2.

The balanced equation:

4 NH₃ (g) + 3 O₂ (g) ----> 2 N₂ (g) + 6 H₂O (g) + energy

<u>Reactants:</u> 4 nitrogen, 12 hydrogen, 6 oxygen

<u>Products:</u> 4 nitrogen, 12 hydrogen, 6 oxygen

Now, all of the elements are equal on both sides and there are no 1/2 coefficients. These are the smallest whole-number coefficients because some of the numbers cannot be further simplified (3).

Bună ziua, mă poate ajuta și pe mine cineva, spunândumi din ce substanțe este formată cărămida și care este formula
Ne4ueva [31]

Answer: De câte cărămizi am nevoie? Pentru un perete de cărămidă cu strat singular, înmulțiți lungimea peretelui cu înălțimea pentru a obține zona. Înmulțiți acea zonă cu 60 pentru a obține numărul de cărămizi de care ar trebui să aveți nevoie, apoi adăugați 10% pentru risipă. Acesta este răspunsul scurt și presupune dimensiuni „standard” de cărămidă și mortar.
