Answer: YY, Yy, and yy are genotypes. Green and yellow are phenotypes.

Explanation: Genotypes are the genes that cause phenotypes (YY, Yy, yy).

Phenotypes are the physical changes caused by a gene, like Blond hair.

Example: If I had recessive blond hair (lowercase genotype), then the genotype is maybe ww, as the dominant trait is white. The phenotype, or physical change is blonde hair.

Britney added 0.05 moles of copper(II) nitrate solution to 0.1 moles of sodium hydroxide solution and

Rama09 [41]

The percent yield of copper hydroxide is 84%

<h3>Stoichiometry</h3>

From the question, we are to determine the percent yield of copper hydroxide

First, we will determine the theoretical mass

From the given balanced chemical equation, we have

Cu(NO₃)₂ + 2NaOH -- Cu(OH)₂ + 2NaNO₃

This means,

1 mole of copper(II) nitrate reacts with 2 moles of sodium hydroxide to produce 1 mole of copper hydroxide

Therefore,
0.05 mole of copper(II) nitrate reacts with 0.1 mole of sodium hydroxide to produce 0.05 mole of copper hydroxide

The theoretical number of moles of copper hydroxide that is produced is 0.05 mole

Now, for the theoretical mass

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of copper hydroxide = 97.56 g/mol

Then,

Theoretical mass = 0.05 × 97.56

Theoretical mass of copper of hydroxide produced is = 4.878 g

Now, for the percent yield of copper hydroxide

Percent yield is given by the formula,

$Percent\ yield = \frac{Actual\ yield}{Theoretical\ yield} \times 100\%$

Then,

$Percent\ yield\ of\ copper\ hydroxide= \frac{4.1}{4.878}\times 100\%$

$Percent\ yield\ of\ copper\ hydroxide= 84\%$

Hence, the percent yield of copper hydroxide is 84%.

Explain atoms contain positively charge protons and negatively charge electrons. why does an ordinary atom have no charge?

tatiyna

An ordinary atom is balanced for instance, lithium has 3 protons and 3 electrons the positively charged proton cancels the negatively charged electron.

Why is the use of inquiry process a practical way to approach science?

just olya [345]

Answer:

Explanation:

Inquiry making is one of the methodical approaches to scientific investigation. Inquiry basically deals with asking question and querying a certain procedure or observation. In almost all the phases of a scientific investigation, the scientist will not cease to keep on asking questions that are connected to the observations and how this can help to further broaden the scope of the experiment. In fact, every investigation in science is an inquiry into a phenomenon and this generates series of questions that need to be satisfied.

Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical for

sp2606 [1]

Answer:

(a) C5H8O2

(b) C2H2Cl2

(d) CH

Explanation:

We need to find the proportion of the atoms in whole numbers. Given the percentages we can calculate the number of moles and find their proportions.

Assume 100 g and given the atomic weights the moles are calculated.

(a) C = 59.9/ 12.01 = 4.98 ≈ 5.00

H = 8.06/1.007 = 8.00

O = 32/15.999 = 2.00

C5H8O2

(b) C= 24.8/12.01 = 2.06≈ 2.00

H = 2.0/1.007 = 1.99 ≈ 2.00

Cl = 73.1/ 35.453 = 2.06 ≈ 2.00

C2H2Cl2

H= 14/1.007 = 13.90

7.16:13.90 ≈ 1:2

CH2

(d) C = 92.30/12.01 = 7.68

H = 7.7 / 1.007 = 7.65

7.68:7.65 ≈ 1:1
