answer : the penguins do

Answer:

B. This is a decomposition reaction and the mass reading will stay the same as time progresses,

Explanation:

Decomposition reactions are when one reactant decomposes (breaks down) into two or more products. They follow the general form of:

AB --> A + B

The law of conservation of mass tells us that when a chemical reaction takes place, no mass is created or destroyed but transforms from one form to another. You can see from the diagram that you have the same number and type of atoms on each side of the reaction.

Answer:

B

Explanation:

Amount of moles of water is 4.36 mol

Explanation: M(C2H2) = 2·12.01 + 2·1.008 = 26.036 g/mol

Amount of substance is n= m/M= 56.8 g / 26.036 g/mol= 2.18159 mol

Water is needed 2·2.18 mol = 4.36 mol

The most controversial ethical issue surrounding modifying human DNA is, according to the text, is that it will lead to the creation of designer children with improvements in intelligence or physical performance.

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid.

The DNA of an individual can be found in almost all of their cells.

The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a small quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Other ethical issues include the possibility of an identity crisis for a person born with genes from three different people as well as the danger of making mistakes in the human genome that could lead to the spread of genetic illnesses in the population.

Thus, it can be concluded that there are various ethical issues of editing human DNA.

Answer:

0.854

Explanation:

The equation of its dissolution in water is: AgNO3 → Ag + (aq)  +  NO3- (aq)

and     AgNO3 →   Ag + (aq)  +  NO3- (aq)

         1 mol          1mol                1mol

            ?  --------   0.854mo

so for finding the value, it is sufficients to complute 1 x 0.854 mol =0.854 mol

so,  0.854 mol is required for the reaction to form 0.854 mol of Ag

Answer: The molar mass of [tex]BF_3[/tex] is 67.81 g/mol

Explanation:

Molar mass is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

Atomic Mass of Boron (B) = 10.81 g

Atomic Mass of Flourine (F) = 18.99  g

Molecular mass of  [tex]BF_3[/tex] = 1 (10.81)+3(18.99) g = 67.81 g

Thus molar mass of [tex]BF_3[/tex] is 67.81 g/mol

Answer: I want to say 1

Answer: 0.16 g H2

Explanation:

Mg+ H2SO4= MgSO4 + H2

Atomic massof Mg is 24

Molecular mass of H2 is 2

So,

24g Mg produce 2 g H2

1g Mg produce (2÷24)= 0.083 g H2

2.00g Mg produce (0.083×2) g H2

   = 0.16 g H2

 0.16g of hydrogen is formed when 2.00g of magnesium.

The mass of hydrogen gas formed when 2.00g of magnesium is equal to 0.165 g.

The chemical equation of a reaction is said to be a balanced equation when the number of atoms of substances is equal on either side of the equation.

Evergy balanced chemical equation must follow the law of conservation of mass according to which the total mass of the substances present on the reactant side should be equal to the total mass of substances present on the product side.

Given, the balanced chemical equation of the reaction of Mg and sulfuric acid:

[tex]Mg + H_2SO_4 \longrightarrow MgSO_4 +H_2[/tex]

One mole of magnesium produces hydrogen gas = 1mol

Given the mass of magnesium = 2g

The number of moles of Mg = 2/24.3 = 0.082 mol

Then the number of moles of hydrogen gas formed = 0.082 mol

The mass of the hydrogen gas = 0.082 × 2 = 0.165 g

Answer:

191.4 grams of cinnabar  are required to obtain 165 grams of mercury.

Explanation:

The balanced reaction is:

HgS + O₂ ⇒ Hg + SO₂

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

Being the molar mass of each compound:

the following mass amounts of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 200 grams of Hg are formed from 232 grams of HgS , 165 grams of Hg are formed from how many grams of HgS?

[tex]mass of HgS=\frac{165 grams of Hg*232 grams of HgS}{200 grams of Hg }[/tex]

mass of HgS= 191.4 grams

191.4 grams of cinnabar  are required to obtain 165 grams of mercury.

Answer:

What effect on the temperature of a boiling liquid and on its distillation temperature is produced by each of the following?(a)A soluble, nonvolatile impurity? It would cause the mixture to boil at higher temperature and increase the distillation temperature.

It would cause the mixture to boil at a higher temperature and increase the distillation temperature.

Distillation is a process involving the conversion of a liquid into a vapour that is subsequently condensed back to liquid form.

During distillation, substances separate based on their boiling points. The boiling point of the mixture varies as vapour rises in a distillation column, due to changes in temperature and pressure. This process divides distillation into stages.

Hence, It would cause the mixture to boil at a higher temperature and increase the distillation temperature.
